good raw material, good technique, high quality, good looking, manykinds of colours, long service
“Seher” aluminum-plastic composite pipes (butt & overlapwelding) are produced with advanced technology and scientificquality management, they meet the international standardGB/T18997.1-2003 strictly. All the production lines are worked bycomputer process, laser diameter survey and ultrasoundcontrol.
Feature of products
1, Innocuity, anticorrosion, light, good pressure resistance andheat resistance, low embrittlement temperature and long servicelife.
2, Little fluid resistance in pipe, no fouling, no pollution,and larger effective pipe diameter.
3, Completely insulate from oxygen, eliminate permeatethoroughly. Can be used to shield communication, defense from kindsof radio-frequency or magnetic interruption, and also be used totransport gas or oil. The pipes can be bended and recover verysoon.
aluminum plastic composite pipe>4)Corrosion Resistant: resistchemical matters or electron chemical corrosion
5)Lower Installation Costs: light weight and ease of installationcan reduce installation costs by as much as 50% over metal pipingsystem
6)Higher Flow Capacity: smooth interior walls result in lowerpressure loss and higher volume than metal pipes
7)Long Life: more than 50 years under normal conditions
8)Recycled and Environment-friendly

20-160mm ppr pipeat preservation and energy conservation of hotwater pipe.5, Light, high pressure resistance: the weight is just1/8 of that of metal, it can bear 5MPa or more in compression test,it also has good toughness and shock resistance.6, Beautiful andpractical: both inner and outer of the pipe is smooth, with littlefluid resistance.7, Easily fix and reliable: use fusing welding noneed to thread rolling, it can finish a joint in just a fewseconds. When it needs to connect with the metal pipe and waterequipment, you can use copper insert fittings.ate(%)
