The advantage of Steel plastic conversion heat shrinkable sleeve

Plastic-to steel transition fittings have good wear resistance, corrosion resistance, impact resistance and good protection against direct light and light aging.

Steel-plastic transition fittings are mainly used to connect PE pipes with other material pipes and pipe accessories.

Easy and fast connection. Transition pipe fittings varieties include straight, elbow, threaded, welded and other forms.

Working principle of Steel plastic conversion heat shrinkable sleeve

Steel-plastic transition anti-corrosion heat-shrinkable sleeve is a kind of steel pipe anti-corrosion heat-shrinkable tube, which is used for the protection of steel-plastic transition joints. It is composed of radiation cross-linked polyolefin base material and special sealing hot melt adhesive. Good bonds are formed on olefin substrates, steel pipe surfaces, and solid epoxy coatings. Exposed pipelines are susceptible to atmospheric corrosion, while buried pipelines are susceptible to soil corrosion and stray current corrosion. Corrosion shortens the service life of gas pipelines and reduces the transmission capacity of the pipelines.

Steel-plastic conversion anti-corrosion heat shrinkable sleeve is an integral structure, or "closed sleeve", which has stronger shrinkage force, creep resistance, aging resistance, impact resistance, heat resistance, and other properties. The hot melt adhesive used in the anti-corrosion heat shrinkable tube has high shear strength and peel strength, strong adhesion to steel pipes, epoxy, and PE coatings, and good sealing performance. The service life is the same age as the pipeline.

It is used for the protection of steel-plastic transition joints. During heating and installation, while the round sleeve shrinks radially, the internal composite adhesive layer melts and tightly wraps the steel-plastic transition joint, forming a firm anti-corrosion body with excellent performance. Excellent abrasion resistance, corrosion resistance, impact resistance, and good resistance to UV rays and light aging.

Steel-plastic transition anti-corrosion heat-shrinkable sleeve can choose a three-layer structure consisting of two-component liquid epoxy primer + inner-coated heat-shrinkable round sleeve. Because the heat-shrinkable sleeve is an integral structure, it has stronger shrinkage force and creeps resistance. , Aging resistance, impact resistance, heat resistance. Suitable for long-term use at a maximum temperature of 70°C. The gas inlet line is the key part for the gas to enter the user from the outdoors. The steel-plastic transition anti-corrosion heat-shrinkable sleeve is used for the protection, sealing, and anti-corrosion heat-shrinkable round pipe of the welding joint of the gas steel pipe and the entrance of the steel pipe through the wall.
