Hot water heating polyurethane anti-corrosion insulation steel pipe

& Hot water heating polyurethane anti-corrosion insulated steel pipe (Manager Bi) Cangzhou Tianze Pipeline Co., Ltd. is a Hebei hot water heating polyurethane anti-corrosion insulated steel pipe manufacturer, polyurethane directly buried insulated spiral steel pipe, black jacket polyurethane directly buried insulated steel pipe, polyurethane foam insulation Seamless steel pipe, polyurethane direct buried insulated steel pipe for central heating, direct buried polyurethane foam insulated steel pipe, black jacket foam insulated seamless steel pipe, black jacket polyurethane insulated spiral steel pipe, yellow jacket polyurethane insulated steel pipe, steel sleeve steel steam direct buried Insulated steel pipes, welcome to negotiate& Directly buried steel-sheathed steel insulated pipe structures are divided into two types according to different sliding methods: internal sliding type and external sliding type.
, Internal sliding type: The insulation structure consists of working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, heat insulation layer, stainless steel fastening steel strip, aluminum foil reflective layer, polyurethane insulation layer, outer steel pipe, Composed of outer anti-corrosion layer.
, External sliding type: The insulation structure is composed of working steel pipe, glass wool thermal insulation layer, aluminum foil reflective layer, stainless steel fastening belt, sliding guide bracket, air insulation layer, outer protective steel pipe, and outer anti-corrosion layer.
&The moisture drainage pipe on the steel casing can not only remove moisture gas in time, but also serve as an alarm signal pipe for daily operation. The thermal compensation of the pipeline adopts high-quality corrugated pipe compensator, which is installed in the casing and made into a directly buried form. There is no need to set up an observation well, and the construction operation is convenient and the construction period is short. Technical parameters: Working steel pipe Steel pipe type: Generally, seamless steel pipes are used for pipe diameters of D and below, and spiral welded pipes are used for pipe diameters of D and above. The specifications and models are DD. Material: seamless pipes are steel, and spiral welded pipes are QB. Implementation standard: Seamless Steel pipe execution standard, spiral submerged arc welded steel pipe execution/standard,. Standard steel casing Steel pipe type: spiral welded pipe material: QB execution standard: spiral welded pipe centrifugal glass wool Product features: The inner steel pipe is made of silicone high-temperature resistant paint (temperature-resistant &℃ ) anti-corrosion coating to effectively prevent corrosion of working steel pipes and extend service life. Pipe ports should be sealed with polyethylene film or three layers of cold-wrapped tape to prevent moisture from entering before installation or water from entering during construction.
At temperatures below ℃, centrifugal glass wool is the best thermal insulation material with light weight and stable geometric shape. It is wrapped with multiple layers of staggered seams, which effectively reduces heat loss. At the same time, the surface measures of the jacket are controlled to prevent the occurrence of cold bridges, thereby preventing the occurrence of cold bridges. The temperature control of the coat's anti-corrosion layer is guaranteed. And it has the characteristics that the physical properties and geometric shape can be fully restored after drying with water. This feature enables the pipeline to adapt to construction conditions in areas with high groundwater levels, bringing great convenience to construction and reducing construction costs.
&Utilizing the characteristics of high strength and good sealing of steel casing, it successfully solved the difficulty of waterproofing and leakage resistance. The steel pipe is used as the outer protective layer, which has the characteristics of high strength, not easy to be damaged and can withstand the load on the upper part of the trap. In order to achieve a long life, the steel outer pipe needs to be anti-corrosion treated to ensure the safety of the heating pipe and can be used in different temperature environments. It is safer and more widely used, especially suitable for high-temperature steam pipeline projects
