Steel sleeve steel insulated steel pipe and its application
Task Steel Pipe Type: Seamless steel pipe is used for diameter of DN150 and below under normal condition, and spiral welded pipe for diameter of DN200 and above is made of DN20-DN1020 material: seamless pipe is 20 # steel, spiral welded pipe is Q235B implementation specification: seamless steel pipe implements GB/T8163-1999 specification, spiral submerged arc welded pipe implements SY/T5037-2000 specification. GB/T9711.1 Specification Steel Tube Type: Spiral Welded Pipe Material: Q235B Execution Specification: Spiral Welded Pipe SYT5037-2000 Centrifugal Glass Cotton Product Characteristics: Inorganic Silicon Low Temperature Resistant Paint (Temperature Resistance (> 400 C) anticorrosive coating is selected for inner steel pipe to avoid corrosion of task steel pipe ineffectively and extend service life. The end of the pipeline is sealed with polyethylene film or three layers of PE cold wrapping tape to prevent the device from entering moisture or water during construction.
Polyurethane insulating steel pipe is suitable for various media in the range of - 50 ~150 C. It is widely used in central heating, cooling and hot oil delivery and heating room, cold storage, coal mine, petroleum, chemical industry, etc. Polyurethane foamed insulating steel pipe has the advantages of light bulk density, high strength, heat insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, non-water absorption, simple and quick construction, etc. It is suitable for various medium insulation and cooling engineering in the range of - 50 ~150 (?) It is widely used in urban central heating, heating room, cold storage, coal mine, petroleum port, chemical industry and other industries, and has become an indispensable product for insulation, waterproof, leak stoppage, sealing and other industrial sectors such as petroleum, chemical industry, power, construction, transportation, refrigeration, etc.
Polyurethane direct-buried insulating pipe is used in heating (cooling) project. Its insulation and sealing effect is obvious. It is used for buried laying. It not only wastes power and increases waste, but also occupies land and uglifies environment. When used in oil and gas delivery, it can meet the requirements of long-distance transportation, eliminates operation and maintenance, meets the requirements of heat preservation and freeze-proof to the greatest extent, increases heating equipment, and is particularly convenient to install, and prolongs the construction period. When used in geothermal and hot spring transportation, meet the cooling requirements and complete the long distance transportation. It is used for water conservancy and mining to meet the requirements of cold proof, antifreezing, heat preservation and anti-corrosion. In addition, there is wide application space for pipeline transportation of chemical materials.
