Electrothermal melting sleeve is a new type of connecting pipe fitting emerging in the anti-corrosion and thermal insulation industries in recent years. Its anti-aging property, connection strength, ring stiffness, etc. are obviously superior to the heat shrinkable belt. In addition, the electrothermal melting sleeve can weld the jacket pipe first, then polyurethane foam, and its construction speed is also significantly faster than the heat shrinkable belt. Therefore, the electrothermal melting sleeve is widely used for the joint repair and connection of heat pipes and oil pipelines.
The new type of insulation pipe interface auxiliary material, electric heating melting sleeve, is developed based on the many shortcomings of direct buried pipeline joint patching in previous engineering examples. It adopts the hot pressing pre embedded alloy electric heating wire process and is produced on an automated production line. The product has stable quality and strong adhesion. By using the matching electric heating melting machine to power the electric heating melting sleeve, welding can be automatically completed. The operation is simple and reliable, and the construction work surface can be large or small, which is convenient and fast. It is a replacement product for the previous direct buried insulation pipe joint patching sheet.

Mainly used for interface connection of thermal pipelines, oil pipelines, natural gas pipelines, and anti-corrosion and insulation pipelines. Features: High adhesive strength, good sealing performance, corrosion resistance, long service life, easy to use. The common product specifications of hot melt sleeve (can be customized according to customer requirements, with unlimited specifications, and the diameter of the outer sleeve: DN200-1880mm). The electric melt sleeve is a new type of connecting pipe fitting emerging in the anti-corrosion and insulation industry in recent years. Its aging resistance, connection strength, ring stiffness, etc. are obviously better than the heat shrinkable tape. In addition, the electric melt sleeve can weld the jacket pipe first, and then polyurethane foam, and its construction speed is also significantly faster than the heat shrinkable tape. Therefore, the electric melt sleeve is widely used in thermal pipelines. The PE pipe sleeve series products for joint coating and connection of oil pipelines are designed for anti-corrosion of buried and overhead steel pipe welded joints and thermal insulation joint coating of insulation pipes. It is composed of radiation cross-linked polyolefin substrate and special sealing hot melt adhesive. The special sealing hot melt adhesive can form good adhesion with polyolefin substrate, steel pipe surface and solid epoxy coating

In rare cases, the hot-melt sleeve also adopts a two-layer external anti-corrosion layer (two-layer PE anti-corrosion) on the steel pipe, with sealed hot melt adhesive in contact with the steel pipe and cross-linked polyethylene on the outer layer. Jacket anticorrosion is composed of foam jacket sleeve (inner layer) hot melt adhesive (middle layer) and base material (outer layer). See the oil and gas industry standard SY/T0413-2002 Technical Standard for Polyethylene Anticorrosive Coating of Buried Steel Pipeline (SY/T4054-2003) Radiation Crosslinked Polyethylene Heat Shrinkable Tape (Set) and SY/T0415-1996 Technical Standard for Rigid Polyurethane Foam Anticorrosive and Thermal Insulation Coating of Buried Steel Pipeline for technical requirements.

Suitable for various pipe anti-corrosion coatings: steel pipe bottom layer, two-layer polyethylene (2PE), three-layer polyethylene (3PE), three-layer polypropylene (3PP), epoxy powder (FBE), insulation jacket, coal tar enamel, petroleum asphalt, etc. The hot melt adhesive of this product has good bonding performance, and after heating and melting, it firmly combines with the above steel coating to form a good anti-corrosion sealing system. It has high peel strength, good anti-corrosion performance, fast shrinkage speed, good sealing performance, good waterproof performance, acid and alkali resistance, chemical corrosion resistance, and good mechanical protection performance. Its service life is the same as that of pipelines, and on-site construction operation is simple with low labor intensity.
