Expense connected with thermowell selection does not end with the initial

purchase. Listed below are some of the reasons for the careful dimensioning of

the Thermowells in this catalog. Note the emphasis on standardizing of bore size,

element (or stem) length and other internal dimensions. You will discover other

benefits to using standard wells as time goes on.

Save On Initial InvestmentStandard wells are produced on a large quantity basis bringing about reduced

cost and improved delivery. Temperature sensing elements are lower in cost

since you are buying larger quantities of particular sizes.

Gain Overall FlexibilityA temperature sensing element in a threaded well also fits a flanged well

downstream, or a socket weld well on main steam. Pull out a Bi-metal thermometer

and insert a test thermometer or thermocouple in that same well. Since these

wells accept several types of sensing elements, instruments may be “swapped

around” to suit changing optional procedures or advancing technology.

Reduce Spare Instrument InventoryUse of standard wells throughout the plant can reduce the number of spare

instruments necessary to insure safe coverage. Less work is required by the

power plant designer in establishing a recommended spare list.

Minimize Down TimeEven if caught without a spare, chances are that an instrument, in a less critical

location can immediately be relocated to a measurement point where a failure

has resulted.

Lengths:± 1/16” on length 12” or less

Versatility and PriceALLOY has the capabilities of meeting all of your Thermowell requirementswhether they be a single piece or very large contract jobs at a competitive price.

SalesALLOY maintains ample finished and semi-finished stock levels to serve distributors,located throughout the USA and Canada. An expedited delivery service is availableupon request.

EngineeringThis catalog gives complete engineering information for the proper selection ofStandardized Thermowells. ALLOY’s engineers are willing and able to help withany design problems.

Manufacturing EquipmentAll wells are machined from solid bar stock on the most modern numerical controlmachines. Bores are produced on deep hole gun drilling machines which producesmooth true holes accurately centered in the sensitive part of the well.

Material - The Longevity FactorIn general, the thermowell material chosen for the installation is governed mainly

by the corrosion conditions the well will face. Recommended materials for various

services are given in the Corrosive Service Guide on page 23. The high polish

given to all stainless and monel wells provides maximum corrosion resistance

and strength. Occasionally, the material consideration is one of strength rather

than corrosion. For example, a stainless steel well may be required for high

pressure water service where otherwise a brass well would be satisfactory from

a corrosion standpoint. Consult the pressure-temperature ratings given for each

well type. The standard materials listed for each well series will cover most

requirements. Alloy carries a wide variety of special materials in inventory to

insure fast delivery of wells. Materials include special grades of Stainless Steel,

Chrome-molybdenum, Steel, Naval Brass, Hastelloy B&C, Nickel and Titanium.

Connection - The Installation FactorIn these pages you will find standardized wells of threaded, flanged (A.N.S.I. and

Van Stone) and socket weld types with standard bore sizes. Threaded wells are

all made in readily welded or brazed materials. This is important for installations

requiring seal welding or brazing. The pipe thread provides the mechanical

strength, the weld merely seals. Flanged wells (other than Van Stone type) consist

of a bar stock well which is solidly welded to a top quality flange. Standard

construction uses a primary “J” groove weld and a bevel groove secondary weld.

Both welds are machined to produce a clean fillet. This double welded construction

eliminates possibility of crevice corrosion and stress problems since no open

joints are exposed from either inside or outside the installation. Socket welding

types of wells are simple to install by merely welding into place. These wells fit

A.N.S.I. standard socket weld couplings or flanges. The resulting installation is

clean and tight.

Insertion Length - The Accuracy FactorThe distance from the end of the well to the underside of the thread, or other

connection means, (designated as “U”) is the insertion length. For best accuracy,

this length should be long enough to permit the entire temperature sensitive part

of the thermometer bulb to project into the temperature medium being measured.

A properly installed thermometer bulb will project into liquid an amount equal to

its sensitive length plus at least one inch. In air or gas, the bulb should be

immersed to its sensitive length plus at least three inches. Thermocouples and

thermistors have short sensitive lengths, therefore can use the smallest insertion

lengths. Bi-metal thermometers, resistance thermometers and liquid-in-glass

thermometers have bulbs with sensitive portions between one and two inches

long. Therefore, the minimum standard insertion length of 2 1/2” must be entirely

immersed in liquid for proper accuracy. Filled system thermometer bulbs may

have sensitive portions from one to several inches in length. Determine the

sensitive length of the bulb before choosing an insertion length. Above all - be

sure that dead length, ie. - that are required to pass thru walls, pipe fittings, etc.,

is taken into account when choosing the necessary well insertion length.

Bore Size - The Interchangeability FactorAlmost any installation uses several types of temperature measuring instruments.

The selection of a standard bore diameter can produce maximum flexibility within

the plant. The same well can accommodate either thermocouple, resistance

thermometer, bi-metal thermometer, or test thermometer. The bore size of wells

shown in this catalog cover the most commonly used temperature sensing

elements as follows:

.260 Diameter Bore: Bi-metal Thermometers (1/4” Stem)

Thermocouples - (#20 Gauge)

Liquid-in-glass Test Thermometers (unarmored)

Other elements having .252 maximum diameter

.385 Diameter Bore: Bi-metal Thermometers (3/8” Stem)

Thermocouples - (#14 Gauge)

Liquid-in-glass Test Thermometers (armored)

Other elements having .377 maximum diameter

Tapered or Straight Shank - The Velocity Rating FactorTapered shank wells provide greater stiffness for the same sensitivity. The higher

strength-to-weight ratio gives these wells a higher natural resonant frequency

than for an equivalent length straight shank well, permitting operation at higher

fluid velocities. Refer to “Velocity Ratings of Wells” on page 6.

Well failures, in most cases, are not due to the effect of pressure and temperature.

The calculations necessary to provide adequate strength, under given conditions,

are familiar enough to permit proper choice of wall thickness and material.

Less familiar, and more dangerous, are the vibrational effects to which wells

are subjected. Fluid, flowing by the well, forms a turbulent wake (called the Von

Karman Trail) which has a definite frequency based on the diameter of the well

and velocity of the fluid. It is important that the well have sufficient stiffness so

that the wake frequency will never equal the natural frequency of the well itself.

If the natural frequency of the well were to coincide with the wake frequency, the

well would vibrate to destruction and break off in the piping.

On the following pages, a recommended maximum velocity rating can be found

for every standard well length and material cataloged. To reduce the complexity

of presenting this information, the ratings given are based on operating temperatures

of 1000ºF for wells made of Carbon Steel (C-1018), A.I.S.I. 304 & A.I.S.I. 316.

Values for brass wells are based on 350ºF operation. Limits for Monel wells are

based on 900ºF service. Slightly higher velocity is possible at lower temperatures.

Where single values appear in the velocity tables, these may be considered

safe for water, steam, air or gas. In the shorter insertion lengths, consideration

is given to the velocity pressure effect of water flowing at higher velocities. The

values in parenthesis, therefore, represent safe values for water flow while the

unbracketted value may be used for steam, air, gas and similar density fluids.

It should be pointed out that the values given are extremely conservative, and

intended primarily as a guide. Wells are also safe if the resonant frequency is

below the wake frequency or if the fluid velocity is constantly fluctuating through

the critical velocity point. If the installation is not hampered by the use of a

sufficiently stiff well, we recommend the values given not be exceeded.

If you have operating conditions requiring special well designs, our Engineering

Staff is available to assist you.

Well failures, in most cases, are not due to the effect of pressure and temperature.

The calculations necessary to provide adequate strength, under given conditions,

are familiar enough to permit proper choice of wall thickness and material.

Less familiar, and more dangerous, are the vibrational effects to which wells

are subjected. Fluid, flowing by the well, forms a turbulent wake (called the Von

Karman Trail) which has a definite frequency based on the diameter of the well

and velocity of the fluid. It is important that the well have sufficient stiffness so

that the wake frequency will never equal the natural frequency of the well itself.

If the natural frequency of the well were to coincide with the wake frequency, the

well would vibrate to destruction and break off in the piping.

On the following pages, a recommended maximum velocity rating can be found

for every standard well length and material cataloged. To reduce the complexity

of presenting this information, the ratings given are based on operating temperatures

of 1000ºF for wells made of Carbon Steel (C-1018), A.I.S.I. 304 & A.I.S.I. 316.

Values for brass wells are based on 350ºF operation. Limits for Monel wells are

based on 900ºF service. Slightly higher velocity is possible at lower temperatures.

Where single values appear in the velocity tables, these may be considered

safe for water, steam, air or gas. In the shorter insertion lengths, consideration

is given to the velocity pressure effect of water flowing at higher velocities. The

values in parenthesis, therefore, represent safe values for water flow while the

unbracketted value may be used for steam, air, gas and similar density fluids.

It should be pointed out that the values given are extremely conservative, and

intended primarily as a guide. Wells are also safe if the resonant frequency is

below the wake frequency or if the fluid velocity is constantly fluctuating through

the critical velocity point. If the installation is not hampered by the use of a

sufficiently stiff well, we recommend the values given not be exceeded.

Staff is available to assist you.

A properly installed thermometer bulb will project into liquid an amount equal to

its sensitive length plus at least one inch. In air or gas, the bulb should be

immersed to its sensitive length plus at least three inches. Thermocouples and

thermistors have short sensitive lengths, therefore can use the smallest insertion

lengths. Bi-metal thermometers, resistance thermometers and liquid-in-glass

thermometers have bulbs with sensitive portions between one and two inches

long. Therefore, the minimum standard insertion length of 2 1/2” must be entirely

immersed in liquid for proper accuracy. Filled system thermometer bulbs may

have sensitive portions from one to several inches in length. Determine the

sensitive length of the bulb before choosing an insertion length. Above all - be

sure that dead length, ie. - that are required to pass thru walls, pipe fittings, etc.,

is taken into account when choosing the necessary well insertion length.

Bore Size - The Interchangeability FactorAlmost any installation uses several types of temperature measuring instruments.

The selection of a standard bore diameter can produce maximum flexibility within

the plant. The same well can accommodate either thermocouple, resistance

thermometer, bi-metal thermometer, or test thermometer. The bore size of wells

shown in this catalog cover the most commonly used temperature sensing

elements as follows:

.260 Diameter Bore: Bi-metal Thermometers (1/4” Stem)

Thermocouples - (#20 Gauge)

Liquid-in-glass Test Thermometers (unarmored)

Other elements having .252 maximum diameter

.385 Diameter Bore: Bi-metal Thermometers (3/8” Stem)

Thermocouples - (#14 Gauge)

Liquid-in-glass Test Thermometers (armored)

Other elements having .377 maximum diameter

Tapered or Straight Shank - The Velocity Rating FactorTapered shank wells provide greater stiffness for the same sensitivity. The higher

strength-to-weight ratio gives these wells a higher natural resonant frequency

than for an equivalent length straight shank well, permitting operation at higher

fluid velocities. Refer to “Velocity Ratings of Wells” on page 6.

Material - The Longevity FactorIn general, the thermowell material chosen for the installation is governed mainly

by the corrosion conditions the well will face. Recommended materials for various

services are given in the Corrosive Service Guide on page 23. The high polish

given to all stainless and monel wells provides maximum corrosion resistance

and strength. Occasionally, the material consideration is one of strength rather

than corrosion. For example, a stainless steel well may be required for high

pressure water service where otherwise a brass well would be satisfactory from

a corrosion standpoint. Consult the pressure-temperature ratings given for each

well type. The standard materials listed for each well series will cover most

requirements. Alloy carries a wide variety of special materials in inventory to

insure fast delivery of wells. Materials include special grades of Stainless Steel,

Chrome-molybdenum, Steel, Naval Brass, Hastelloy B&C, Nickel and Titanium.

Connection - The Installation FactorIn these pages you will find standardized wells of threaded, flanged (A.N.S.I. and

Van Stone) and socket weld types with standard bore sizes. Threaded wells are

all made in readily welded or brazed materials. This is important for installations

requiring seal welding or brazing. The pipe thread provides the mechanical

strength, the weld merely seals. Flanged wells (other than Van Stone type) consist

of a bar stock well which is solidly welded to a top quality flange. Standard

construction uses a primary “J” groove weld and a bevel groove secondary weld.

Both welds are machined to produce a clean fillet. This double welded construction

eliminates possibility of crevice corrosion and stress problems since no open

joints are exposed from either inside or outside the installation. Socket welding

types of wells are simple to install by merely welding into place. These wells fit

A.N.S.I. standard socket weld couplings or flanges. The resulting installation is

clean and tight.

Insertion Length - The Accuracy FactorThe distance from the end of the well to the underside of the thread, or other

connection means, (designated as “U”) is the insertion length. For best accuracy,

this length should be long enough to permit the entire temperature sensitive part

of the thermometer bulb to project into the temperature medium being measured.

Expense connected with thermowell selection does not end with the initial

purchase. Listed below are some of the reasons for the careful dimensioning of

the Thermowells in this catalog. Note the emphasis on standardizing of bore size,

element (or stem) length and other internal dimensions. You will discover other

benefits to using standard wells as time goes on.

Save On Initial InvestmentStandard wells are produced on a large quantity basis bringing about reduced

cost and improved delivery. Temperature sensing elements are lower in cost

since you are buying larger quantities of particular sizes.

Gain Overall FlexibilityA temperature sensing element in a threaded well also fits a flanged well

downstream, or a socket weld well on main steam. Pull out a Bi-metal thermometer

and insert a test thermometer or thermocouple in that same well. Since these

wells accept several types of sensing elements, instruments may be “swapped

around” to suit changing optional procedures or advancing technology.

Reduce Spare Instrument InventoryUse of standard wells throughout the plant can reduce the number of spare

instruments necessary to insure safe coverage. Less work is required by the

power plant designer in establishing a recommended spare list.

Minimize Down TimeEven if caught without a spare, chances are that an instrument, in a less critical

location can immediately be relocated to a measurement point where a failure

has resulted.
