Steel-Plastic Pipe Supplier-GNEE
Advantages and disadvantages of steel-plastic composite pipe
Advantages:
1, retains the traditional metal pipe steel and strength, far better than plastic pipe, aluminum-plastic pipe.
2, with a smooth inner wall, friction resistance of small non-scaling characteristics, the outer wall is more beautiful and luxurious.
3, light weight, good toughness, impact resistance, high compressive strength; applicable temperature wider -30 ℃ ~ 100 ℃.
4,Connections with fittings can be stranded, socket, flange, groove, welding, etc., a variety of ways, labor-saving.
5,The difference of thermal expansion coefficient of the connection parts with the guest parts is small, which is safer and more reliable.
6,Reasonable price-performance ratio, low overall cost, more economical than copper and stainless steel pipe.
Disadvantages:
1, High cost of construction.
2, installation time-consuming and laborious.
3, can not completely solve the problem of water pollution in the connecting part of the pipe fittings. The middle of the steel belt was punched a lot of holes, making the inner and outer layers of the PE organic combination into one, thus solving the problem of steel and plastic composite, but at the expense of steel-plastic pipe oxygen barrier properties, and, due to the presence of steel on the network of holes, largely reduces the pressure-resistant strength of this type of steel-plastic pipe, high-pressure working conditions, it is easy to appear pipe local bursting.
