Can performance pipe polyethylene piping be joined?
CAUTION — Performance Pipe polyethylene piping products cannot be joined with adhesives or solvent cement. Joining by hot air (hot gas) welding or extrusion welding techniques and joining by pipe threading are not recommended for pressure service. Polyethylene plastic pipe does not readily conduct electricity.

What is polypropylene pipe?
Polypropylene Pipe shall be manufactured from natural virgin copolymer polypropylene material with no added plasticizers, pigments or re-grind, manufactured to Sch. 80 dimensions with a pressure rating of 150 psi when measured at 68°F (20°C). Pipe shall be capable of conveying fluids up to 176°F (80°C).

Does socket welding affect the chemical resistance of polypropylene?
Socket welding does not affect the chemical resistance of the polypropylene, nor does it influence the inner pressure resistance of the assembled pipes and fittings. The pipe to be welded must be cut, chamfered and peeled if necessary.

What type of fittings are used in a Hot Weld connection system?
Series of fittings FITTINGS, METRIC SERIES ISO-UNI designed for conveying fluids under pressure with a hot weld connection system (socket welding). Technical specifications Size ranged 20 ÷ d 110 (mm) Nominal pressurePN 10 with water at 20° C

welding method is documented in DVS 2207 Part 11 - Polypropylene. Butt fusion welding is most commonly used for larger size piping, especially on pipe sizes that are larger than 63mm outside diameter. However, spigot ended fittings for butt fusion welding are also available in smaller sizes and this jointing method will produce excellent ...

piping systems can use heating element socket welding, heating element butt welding or the no-contact infrared (IR-Plus®) fusion technology developed by GF. The internal pressure resistance is ensured through long-term testing in accordance with EN ISO 9080 and certified with the value of MRS 10 (minimum required strength).
