What are the advantages of plastic steel composite pipes?
The thermal expansion coefficient of the connection part with the pipe fittings is small, and the utility model is safer and more reliable;
And the pipe can be connected by means of wire cutter, socket, flange, welding groove, etc., a variety of ways, and labor
The utility model has the advantages of smooth inner wall, small frictional resistance and no fouling, and the outer wall is more beautiful and luxurious; 3, light weight, good toughness, shock resistance and high compressive strength; applicable temperature is wider from -30 DEG C to 100 DEG c;
Retains the traditional metal pipe steel and strength, far better than plastic pipes, aluminum pipe;The fire inside and outside the plastic pipecoating plastic steel pipe
