Detailed Product Description: | Polyurethane insulation pipes for its excellent performance, easy construction and long service life (30 -50 years) and much people welcome their structure: the outer protective layer, insulation layer, anti-leakage layer of three parts, the outer protective layer material is polyurethane jacket tube or fiberglass or other materials. Laying methods are buried, aerial, trench three ways. Features: 1, reduce project cost. 2, low heat loss and save energy. 3, good anti-corrosion, insulation performance, long service life. 4, small footprint, fast construction, favorable environmental protection. 5, the safety. Polyurethane insulation pipes buried pipe insulation, also known by the transmission medium, working steel, foam insulation, polyethylene plastic outer sheath tube, followed by combination of equipment out. Three-tier structure from the inside to the outside of the first layer: Working pipe layer according to the requirements of customers design and selection generally seamless (GB8163-87) spiral welded pipe (GB9711-88; SY/T5038-92) and Longitudinal (GB3092 -93). Advanced steel surface after shot blasting process, steel rust rating of up to GB8923-1988 standard of Sa2 level, surface roughness up GB6060.5-88 standard R = 12.5 microns. Second layer: polyurethane thermal insulation in the cavity with a high pressure foaming machine pipe is formed between the outer sheath of the disposable liquid injected from a rigid polyurethane foam. Commonly known as "pipe-in-pipe foaming process." First, its role waterproof, and second insulation, three heating network is to support the weight. When the transmission medium temperature: -50 ℃ -120 ℃, the choice of rigid poly-ester foams do semicarbazide insulation. Third layer: High density polyethylene protective layer of a certain thickness preformed black (yellow) plastic pipe, its role first, polyurethane insulation protection against mechanical damage a hard object, the second is anticorrosion and waterproof. Polyethylene outer tube made of high-density polyethylene material with high mechanical strength and excellent corrosion resistance, can protect the pipe to avoid damage caused by external factors in the transportation, installation and use. Manufacturing jacket pipe should be added antioxidants, UV stabilizers and carbon black. Production 1, 2 feeding, extrusion 3, 4 molds, cooled 5, traction 6, 7 inner surface corona treatment, cutting 8, 9 inspection, product description A. polyethylene pipe easy to aging, such as open storage is appropriate canopy cloth and other objects covered dump should stay away from high heat and ignition sources, pipe insulation made after the ban exposure, quenching, otherwise polyethylene pipe easy to crack, affect product performance and service life. B. Transport and wear tube process, should avoid rough handling, hooks too small, tough, excessive force, otherwise easily lead to polyethylene pipe broke, scratched or torn. C. adjustable pipe wall thickness, thickness, color according to user requirements, due to different pipe wall thickness, insulation thickness is approximately the number of actual thickness should be calculated. D. supporting bracket and pipe, plastic plugs, two flanges, welding, torch, thermal belt complete. E. table allowable deviation is based CJ/114-2000 industry standards. The formula is: when the external diameter ≤ 400mm, and the upper and lower deviation = 0.1 × 0.2 nominal wall thickness outside diameter ≥ 400mm, and the upper and lower deviation of the nominal wall thickness = 0.15 × 0.2 |
