Plastic steel composite pipe what are the disadvantages?
Retains the traditional metal pipe steel and strength, far better than plastic pipes, aluminum pipe;The fire inside and outside the plastic pipe plastic composite pipe
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, -30 DEG C, ~100 DEG c;
In the middle of the strip is playing a lot of holes, making the PE organic combination of the inner and outer layer as a whole, so as to solve the problem of composite steel and plastic, but at the expense of the oxygen barrier property, steel plastic tube and, due to the presence of hole net strip, greatly reduced the compressive strength of this type of steel tubes, conditions working under high pressure, prone to local pipe burst.
And the pipe can be connected by means of wire cutter, socket, flange, welding groove, etc., a variety of ways, and labor;5, and the pipe fittings connecting parts, thermal expansion coefficient is small, more safe and reliable;6, the price performance ratio is reasonable, comprehensive cost is low, more economical than copper tube and stainless steel tube.
