Product Q&A

Q:How are the pressure ratings of PE pipes classified? How to choose?

PE pipe pressure ratings (PN) are categorized into PN0.6, PN0.8, PN1.0, PN1.25, PN1.6, etc., indicating nominal pressure in MPa. Selection should consider the working pressure, flow rate of the medium, and the laying environment, such as burial depth and external load.

Q:If a PE pipe is damaged or leaking, how to repair it?

For minor damage, use PE repair patches (applied via hot-melt bonding) or special sealants for temporary fixes, suitable for low-pressure scenarios. Major damage or breakage requires removing the damaged section and re-connecting using hot-melt or electro-fusion fittings for a secure joint.

Q:What are the connection methods of PE pipes? Which one is the most reliable?

Hot melt connection involves heating pipes and fittings, melting contact surfaces, and butt welding. It is ideal for same-specification pipes, providing strong sealing and long service life, making it the most reliable and popular method.Electrofusion connection uses electricity to heat the resistance wire in the fitting, melting contact surfaces to join pipes. It suits complex conditions like tight spaces and varying specifications. Flange connection is used for transitioning to metal pipes or
