The first layer: the seamless pipe (GB8163-87) spiral welded pipe (GB9711-88; SY / T5038-92) and straight seam welded pipe are generally selected according to the design and customer requirements (GB3092-93). After the surface of the steel pipe is treated by advanced shot blasting process, the steel pipe can reach Sa 2 in GB8923-1988 standard, and the surface roughness can reach R=12.5 Microns ukax GB6060.5-88 estándar. ukankiwa.
The second layer: polyurethane insulation layer with high pressure foam machine in the cavity formed between the steel tube and the outer protective layer once injected into the rigid polyurethane foam plastic stock solution. Namely commonly known as the "tube in the tube foaming process". Its role is waterproof, two is heat preservation, three is to support the weight of the heat net.
