Pipeline Supports

Introduction

A pipe support is a device or assembly or structural component that is

used tosupport a set of pipe lines or duct lines. It transmits environmental loads

from the

piping systems to the attached building or structure. CADDS PipeSupports allows

you to create, modify, manipulate, report and draw pipe supports, shipand plantdesign projects.

Pipe Supports can be classified into two categories.

Standard catalog supports Fabricated supports

Standard Catalog Supports

Standard catalog supports consists of the following:

Hangers

Guides

Anchors Sliding supports

Constant and variable load spring supports and hangers

Sway struts (two way restraints) Snubbers (used to dampen vibration)

Fabricated Supports

Fabricated pipe supports are made up of one or more structural members

assembled together to support a set of pipe lines. A pipe support membercan be

made from various cross sections such as angles, flat bar, channels and I -beams.

Fabricated pipe supports can contain various ready made peripheral items

such as

clamps, u-bolts, sliding pads and attachment pads. Pipe supports alsoincludeinformation such as weight, material type, paint code, label and cross

sectiondimensions.CADDS Pipe Supports deals only with fabricated pipe supports. It allows

you to

create, modify, manipulate, report and draw two basic types of

objects.

Pipe support members

Pipe support units

For these objects you can

Establish pipe support environment parameters

List pipe support environment parameters

Create pipe support models

Modify pipe support models

Manipulate pipe support models Generate pipe support labels

Report pipe support attributes

Generate pipe support database

Produce installation drawings

CADDS Pipe Supports automatically calculates and checks the

dimensional parameters, such as cross section size, pipe support

width and height,

clamp type, tolerance and clearance distances.

Pipe supports can be modeled in stand-alone mode or related to

the pipe lines theysupport. Though, ultimately all the pipe supports should be

related to pipe lines, a

pipe support in stand alone mode is easier to manipulate while

modeling.

Pipes clamps help keep pipes in place whether on the ground,attached to the ceiling or up against a wall.

For pipes to stay where they are installed, they are usually

connected to support systems that keep them in place. Pipes can

be supported from below using brace supports, from above

using pipe hangers and, for pipes running up and down, with

clamps that adhere them to the wall. There are many different

types of pipe supports in these

categories.

The length of cradle bottom is

1/3 of pipe

It means the pipe of 24 inch, the

length of cradle will be 8 inch.

The angle of the support is 120

Definitions

Pipe Support Member

A member or pipe support member, is a structural element. It isrepresented by a

local nodal figure associated with related model graphics and

non-graphical

attributes. The model graphics representation can be any one of

the following:

Nspline projection axis

Nspline projection axis with related cross section profile

Set of NURB surfaces

Solid Set of closed co-planar strings representing the member

surfaces (SMS display

mode)

The various model graphics representations of a pipe support

member are illustrated.

Pipe Support Unit

A pipe support or a pipe support unit is a collection of one ormore pipe support

members that are related to each other, and comprise a single

logical unit. A pipe

support unit denotes all the members and attached components

such as pads,

snips, clamps, sliding pads, cable trays and tubestraps. A pipe

support unit with

pad and snip is illustrated.

Pad

A pad is a small planar plate that lies between the attachment member ofa pipe

support and the structural object on which the pipe support is erected.

Snip

A snip is a 45 degree cut at the end of a pipe support member.

Sliding Pad

A sliding pad is a small plate which lies between a pipe support member

and the

pipe line it supports. Optionally there should be only one sliding pad foreach pipeline. A sliding pad is stored as a non-graphic property on the related pipe

line.

Clamp

A clamp is a device used to fasten a pipe line onto a pipe support

member. A clampis stored as a non-graphic property on the related pipe line.

Cable Tray

A cable tray is a device that takes the weight of electrical or control

cables whichare routed in groups, from one connection point to another. A cable tray

is createdas a local nodal entity.

Tube Strap

A tube strap is a device used to fasten a tube onto a pipe support member.

Tubestrap is stored as a non-graphic property on the supporting member.

Attachment Points

An attachment point is the location at which a pipe support is attached to

anexisting structural object.

Types of Pipe Supports

For pipes to stay where they are installed, they are usuallyconnected to support systems that keep them in place. Pipes canbe supported from below using brace supports, from above using

pipe hangers and, for pipes running up and down, with clamps thatadhere them to the wall. There are many different types of pipesupports in these categories

Pipe Hangers

o Because most above-ground pipes in residential andcommercial buildings are installed overhead, pipe hangersare the most common form of pipe supports. These come innumerous styles; the most common types are strap-style,hook-style, channel-style and clamp-style. Strap-style pipehangers are made of a thin, flexible piece of metal or othermaterial that wraps around the pipe and is then attached tothe ceiling. Hook-style pipe hangers are made into a J-shape, the longer end of which is attached to the ceil ing; thepipe rests on the hook. Channel-style pipe hangers are very

wide J-hooks and can help conceal the pipe as it supports it.

Pipe Risers

o Pipes that rest against the ground typically rest on risers that

help keep them secure to the ground. Pipe anchors are risesthat rigidly restrict any vertical movement caused by thepipe's internal flow or external forces. Shock-absorbing pipesupports allow some movement by the pipe but swallow anyvibrations or excess movement; they are good for pipes thatmove a great deal as a result of high-feed or inconsistentflow. Insulated pipe supports minimize energy dissipation

and reduce the effects of differing temperatures that occur atthe support.

Vertical Clamps

o There are a number of different pipe clamps that can beused to attach vertical pipes to walls. Saddle clamps use topand bottom plates that are secured by bolts and aredesigned to absorb vibration and heat from high-pressurefeed. Gang clamps are made of an angled piece of strongmetal, the ends of which are bolted to the wall. They areuseful for attaching several pipes within close proximity ofeach other because of their minimal use of space. Strap-style pipe hangers can also be used to attach vertical pipesto the wall in the same way they can be used in overhead

areas.

General Pipe Clamps

o There are also hundreds of different types of pipe clampsthat can be used to adhere pipes to other objects. Thesepipe clamps typically use some kind of bolt mechanism; theymay support the pipe by attaching to themselves or they maybe bolted to a wall or elsewhere.
