Composite Insulation Steel Pipe

Spiral welded steel pipe is a steel strip coil plate of raw materials, often warm extrusion molding, with automatic double wire welding double-sided submerged arc welding technology with spiral seam pipe. Thermal insulation pipe refers to after processing the heat preservation technology, in different working conditions and medium to ensure work steel pipe under the action of outside temperature and surface temperature meet or meet the use requirements of steel pipe.

Steel  composite insulation steel pipe is one of the underground buried pipes, with the absence of concrete structures can also be buried underground, the work carbon steel pipe thermal expansion of the outer tube, reducing the cost of materials, shorten the construction date, and to ensure the safety of the heating pipe, can be in different temperature environment safer is widely used, especially suitable for high temperature steam pipeline project. The temperature can reach 150 ℃ to 450 ℃. Three layer PE pipe port generally choose polyethylene film or cold wind belt sealing, prevent before installation or construction into the moisture or water. Heat preservation material multi-layer emperical bandage, effectively reduce the heat loss, at the same time adopt measures to control the coat surface, prevent cold bridge, so that the coat anticorrosive layer are obtained by temperature control. Bandaging with heat preservation material layers of aluminum foil reflector, effectively reduce the heat loss, make steam pipeline more economic and reasonable. Hydrophobic system adopt totally closed form, flexible layout, reasonable structure, safe and reliable. Moisture removal on the coating steel pipe can both wet gas generated in time, and can be used as daily operation of the alarm signal pipe. Pipeline thermal compensation using high-quality bellows compensator, and should be installed to the casing, make form of directly buried, do not need to set up the observation well, convenient operation, short construction period. 2.5 MPa, below 350 degrees Celsius is suitable for conveying steam or other medium, this product is made from steel tube outer protective layer, has high strength, not easy to damage, maintenance is simple construction, long service life.
