It is mainly composed of base material and hot melt adhesive. Our company adopts unique hot melt adhesive formula to ensure the adhesive strength of the product in use and thus ensure the construction quality. Optimization of the design of the new heat shrinkable tape (set) is easy to site construction, fast shrinkage, short operating time, low construction costs, with excellent water vapor permeability, chemical corrosion resistance, insulation and aging resistance and other properties, is the ideal material for pipeline anticorrosion thermal insulation system. Among them, three layers of reinforced fiber type heat shrinkable tape (set) is in a layer of substrate, a layer of adhesive coating between a layer of reinforced fibers, adhesive strength and higher tensile strength, contraction faster, the effect is also better. Mainly used for oil and gas pipeline joints to fill the mouth of the anticorrosion, patching, can also be used for pipeline damage repair. This product is suitable for 3PE steel pipe, 2PE steel pipe, epoxy powder coating, thermal insulation pipe jacket skin and polyethylene drainage and sewage pipeline pipeline patching, patching.

Some customers react that the product does not shrink, and the contraction speed is slow
1, to consider whether there is a sequence error in the construction baking process, such as horizontal baking will appear similar phenomenon, should be longitudinal baking (above and below).
2, the head and tail of the product is about 300-400 meters a circle, due to the reason of irradiation dose, resulting in irradiation dose is too large or too small, resulting in shrinkage of the base material is too large or small, such a situation is a very rare phenomenon.
Solution: The correct use of shrink belt construction method, pay attention to observe the reaction when the shrink belt is baked and broken, in exchange for another product to continue testing, if it is really a quality problem, should immediately stop using, to the manufacturer contact, replace or return.
