XPAP алюминия пластиковые композитные трубы

XPAPaluminum-plastic composite pipe, the middle layer is butt or lap welding aluminum layer. Inner and outer are both PEXb material, between layers we adpote special hot melt adhesive. Because of the structure of PEXb, Crosslinking Density is far higher than PEXa, which has improved the pressure resistant under the high temperature. Features: XPAPcomposite pipes implement GB/T 18997-1-2002,GB/T 18997-2-2002 standards. Long-term working temperature is 95 degrees. Long term working pressure is 1.25Mpa. Bursting pressure is 6-9 Mpa. Under 200 degrees, it will be never deformed. According to ISO/DIS9080 standard, we can use this pipes for 50 years. application cold or hot water pipe system Central air-conditioning piping system Solar pipeline system oil transportation sleeve of wire or cable heating installation on floor and wall,snow-melting devices for buildings in northern,park,air port
