Applications of Suntown PE(X)-AL-PE(X) pipe:

Underfloor heating is a hygiene and high-class heating system, which has been widely used in developed countries, and will be adopted gradually in other countries. Besides underfloor heating system, suntown pe(x)-al-pe(x)composite pipes can be used in areas as below:

l    Heating system of caliduct and wall, the equipment of snow melting in cold regions

l    Heat and cold pipes for life, solar energy water heater, irrigation engineer in agriculture

l    Pipes for coal gas and natural gas, air-condition and blower

l    Pipes for electric wire and cable

l    Pipes for oil and industrial liquids transportation
