first layer: steel pipes, according to the design and the customer's requirements the General selection of seamless pipe (GB8163-87) of spiral welded pipe (GB9711-88; SY/T5038-92) and longitudinal welded pipe (GB3092-93). its core tube tube trail for "φ 22, and 25, and 32, and 38, and 45, and 57, and 76, and 89, and 108, and 133, and 159, and 219, and 273, and 325, and 377, and 426, and 478, and 529, and 630, and 720, and 820, and 920, and 1220"; pipe surface after advanced of threw pills except rust technology processing Hou, pipe except rust grade can up GB8923-1988 standard in the of Sa2 level, R=12.5 surface roughness of GB6060.5-88 standard micron.

second layer: polyurethane insulation layer, with high-pressure foaming machine in protective coverings in steel pipe cavity formed between one-time injection of rigid polyurethane foam in the liquid. commonly known as "pipe in pipe foam technology". their role is a waterproof, thermal insulation, three are supporting hot net weight. "its insulation layer thickness for 30mm-150mm"; when the medium temperature:-50 ° c-120 ° c, use rigid polyurethane-urea acid ester foam insulation.

third layer: protective layer of high density polyethylene, prefabricated wall thickness of a certain black (yellow) plastic pipe, after corona treatment, in reserve. its role is the protection of polyurethane insulation layer from damaged mechanical hard objects, the second is anticorrosive waterproof. FRP pipe and pipe.
