PPSU (polyphenylsulphone) belongs to the high-perfomance technical plastic materials and has been suc-cessfully used in the production of fittings for potable water supply sys-tems for many years.
It is resistant to high temperatures (high – temperature dimensional sta-bility> 200 ºC), corrosion and incrus-tation. It ensures long-therm stability even in pipes within walls. Due to the high impact value and insensitivity to stress cracking of the material, the fittings are highly robust and insensi-tive to shocks.

Poliphenylsulfone (PPSU), raw mate-rial of HTPpush fittings, generally is resistant to attack from many chemi-cals which make it suitable for use in many process applications. PPSU is inert to most acids, bases, salts and a variety of organic media, with certain limits of concentration and tempera-ture. Consequently:
• HTPpush fittings are used not only for drinking water, water for general use but also for the con-veyance of aggressive liquids.
• HTPpush fittings may be in con-tact with materials commonly used in indoor installations wi-thout chemical attack. It is very important to pay attention to the data sheet for the usual mate-rials used in contact with fittings (adhesive, PUR, thinners…). The data sheet of these chemicals usually specifies if their chemi-cal composition attack to poly-meric parts. The fittings with metallic threads should not be considered as metallic parts be-cause chemicals on the thread can affect to the PPSU due to the gases occasioned by the ad-hesive.
So, the Chemical Resistance Lists in this section serves as a useful guide in this respect. The information is ba-sed on experiments, immersion and, when available, on data from tests which include temperature and pres-sure as stress factors. The test refe-rred to have been carried out partly by Solvay and partly by the Internatio-nal Standardization (ISO) or National Standards Organization.
It is possible in especial cases to ca-rry out appropriate tests with specific
mixture. Suitable test equipment is available for this purpose, which we regard as part of our service to the customer. We are always willing to give individual advice at any time.
Following the assertions outlined be-fore the attached lists should be re-garded as a valuable tool for finding the most suitable material for a given application.
The lists have been compiled based on ideal and mostly simplified con-ditions of laboratory testing and field applications are subjected to wor-king conditions that might be defined by more complex factors. So, users must test materials in real operating conditions before subjecting them to potentially hazardous applications.
Thus, if it comes to material decisions and there is a need for checking a proper material, please do not he-sitate to contact with HTP, based on practical experience with polymer piping system applied in industry and chemical engineering.
The Chemical Resistance Lists, for PPSU, have the following sections:
• Adhesives• Antispotting • Descalers• Disinfectants• Food • Fuel• Grease• Oil• Inorganic products• Medical products• Organic Products• Others
When the chemical substance pas-ses inside the fitting, internal EPDM seal must be considered. EPDM is a termopolymer made from ethylene propylene monomer. EPDM has good abrasion and tear resistance and offer excellent chemical resistance to a variety of acid and alkalines. It is susceptible to attack by oils and is not recommended for applications invol-ving petroleum oils and gases. It has good ozone resistance and it is fairly good with ketones and alcohols and has an excellent range from -40ºC to 150 ºC.

6 INSTALLATION REGULATION
6.1 GENERAL INSTRUCTIONS
Observe the applicable national and international regulation on installa-tion, accident prevention and safety when installing piping systems, as well as the instructions in this Tech-nical Information.
Also observe the applicable laws, standards, guidelines and regulations (e.j. DIN, EN, ISO…) as well as regu-lations on environmental protection, provisions of professional associa-tions and regulations of the local pu-blic utility Companies.
The applicable technical regulation, standards and guidelines have to be observed during the installation of heating and potable water. Technical building Code (CTE, HS4) must be ac-complished in installations done in Spain.
Areas of application not contained in this Technical Information (special applications) require consultation with HTP. For detailed advice, please contact the HTP Technical Depart-ment. Installation must only be ca-rried out by specialists.
When using HTPpush system, the following instructions have to be observed:
1. For threaded connections, HTP recommends the use of sealing wire that meets the requirements of EN 751-2. If liquids thread sealants are used, it is very important to pay attention to its data sheet and to be sure about chemical compatibility.
2. Prevention of air locks. Pipes runs must be laid so that no air locks are possible. At the lowest point in the system, there must also be a way of draining the pipeline.
3. Protection against uv irradiation. Exposure to UV irradiation over an ex-tended period will damage the HTPpush system. For this reason, the pipes and fittings should not be stored outdoors. If necessary, they must protec-ted against UV-light.
4. Pipework may be laid in the ground (when the applicable national regula-tion allows it) under the following conditions:
• The pipes must be laid in a bed of sand.• The pipes must be covered with fine-grain sand to such an extent that
there is no danger of damage to the pipe when the later fill material is applied.
• There must be no moveable loads affecting the pipes laid in the ground.• The fittings and the pressure sleeves must be protected against direct
contact with the ground by a suitable corrosion protection agent.
5. Contact with solvents. Direct contact of HTPpush components with sol-vents or solvent containing varnishes, paints, greases, sprays, adhesive strips, etc. must be prevented. The solvents can attack the plastic compo-nents of the system.
6. Protection against frost. Filled HTPpush system must be protected against frost. The system is suitable for the following antifreeze agents and concentrations:
• Ethylene glycol (antifrozen N). May be used up to a concentration of 50 % maximum. This concentration is equivalent is equivalent to frost protection down to a temperature of 38 ºC.
• Propylene glycol. May be used up to a maximum concentration of 25%. It is used primarily by the food processing industry. A concentration of 25% provides frost protection down to 10 ºC.
• At higher concentration of both products, stress crack may occur in the system.

A pipe fastening system that is in ac-cordance with regulations is subject to the following requirements:
• The fastening system must ab-sorb all occurring forces.
• The loads upon the pipes (e.g. caused by deflection and elon-gation) must be kept as low as possible.
• The pipework must be held fir-mly in the intended position.
Fixed points. The fixed points must be calculated in such a way that all occurring forces, in particular tensile forces, can be absorbed without any ensuing damage. The arrangement of the fixed points divides the pipeli-ne system into separate sections, in which the linear expansion has to be absorbed.
Loose points. The loose points su-pport the pipes and must allow move-ments of the pipe in an axial direction without risk of damage to the pipe. Only the weight forces of the pipe sys-tem need to be included in the analy-sis.
∆L = α ∙ l ∙ ∆T∆L = Thermal lineal expansion of pipe, mm

l = Initial length of pipe,m∆T = Temperature difference,K
Thermal linear expansion. Materials expand when heated and contract again when cooling down . Due to the large differences in temperature in the system, the pipes in a hot water and heating system must be fixed in such a way that linear expansion in compensated for in curves or especial expansion bends. The thermal lineal expansion is calculated using the following equation.
Expansion compensation. The va-riation in length caused by tempera-ture differences must be taken into account during the planning phase. In order to keep the occurring stresses within acceptable ranges, the varia-tion in length must be compensated
appropriately. There are two options available to achieve this compensa-tion:
• Expansion compensation using bending legs and U-pipe bends.
• Expansion compensation using compensators.
In most cases, directional changes in the pipe routeing can be utilized to absorb the variation in length. Should the directional changes not be suffi-cient for this purpose, an U-pipe bend must be used.
lB=K∙ √(d∙∆l)lB = length of the bending leg, mmK = material-dependent constant
d = Outer pipe diameter, mm∆l = Variation in length, mm
Bending legs. In order to determi-ne the specific direction in which the expansion compensation is steered, the directional change is installed be-tween two fixed points. As a rule, the pipes are arranged in right angles at the directional changes. The variation in length of one leg produces ben-ding in the other leg. If all legs are of a sufficient length, ensuring that the emerging expansion tension does not become excessive, the system can flexibly absorb the variation in length.

Pretensioning. If, during installa-tion, an expansion bend is already pre-stretched by the length V against the subsequent length variation and is thus “pre-tensioned”, the length of the bending leg lBV can be reduced.
lBV = lB∙ √1 - ∆lv/∆l lB = llength of bending leg without
pre-tensioning, mm∆l = Variation in length, mm
∆lv = Pre-tensioning, mmlBV = length of bending leg with
pre-tensioning, mm
Expansion bends. Where it is not possible to achieve compensation by introducing directional changes into the pipe routeing, the use of a expan-sion bend becomes necessary. For the implementation of the expansion bend, the length lB of the bending length and the width bmin of the ex-pansion bend must be taken into ac-count. It is preferable to position the expansion bend in such a way that the lengths l1 and l2 are equal.
bmin = 2 ∙ ∆l + SAbmin = minimum width of the expansion bend, mm
∆l = Variation in length, mmSA= safety clearance (150 mm)

8.5 PEAK FLOW
Part 3 of DIN 1988 gives a simplified as well as a detailed calculation pro-cedure for determining pipe diame-ters. It is due to theses different ways of calculation that the suitable calcu-lation procedure can be found for all kinds of requirements. The calcula-tion steps are the following:
• Determination of total flow rates and allocation to pipe sections. From the farest tapping point to the supply line, all calculated flow rates are summed up and the total flow rates are allocated to the corresponding line sections.
• Determination of peak flow from total flow. For pipe system design pur-pose, all taps are generally assigned their rated flow values. Simultaneous water tapping depends on the type of use (e.g residence or communal ins-tallations). Generally it can be assumed that not all the taps will be open at the same time.

8.6 FLOW RATES
For sound insulation reasons and in order to limit water hammer, the cal-culated flow rate value must not ex-ceed the following values ( HS4, point 4.2.1).
• Metallic pipes: 0.5-2.0 m/s• Thermoplastic and multilayer
pipes: 0.5-3.5 m/s
8.7 RESISTANCE COEFFICIENTS
There are different criteria to calcu-late resistance coefficients. Besides when the liquid flow throws a pipe, it also looses energy when it chan-ges direction. The liquid must then overcome extra resistance. The table below gives an overview of the resis-tance coefficients of the different fit-tings and the corresponding number of meters of piping.

8.8 RADIATOR CONNECTION
HTPpush system allow the complete installation of heating facilities from the heat generator to the radiator. Both single pipe connections and two-pipes connections are possible. Not only in a new building, but also in the field of the reconstruction of old buildings the push-fit connection te-chnique, which allows an installation without soldering and welding, shows its clear advantages.
All installations must be carried out in line with the currently valid regu-lations and standards, inter alia ther-mal insulation, sound protection and fire protection.
Important information: Installations such as solar or long-distance ener-gy installations, which are operated with working temperature exceeding 95 ºC, must not be connected directly to PEX or multilayer PE/AL/PE pipes!
