                Heat Shrinkable Rolls

                Product details

                Heat Shrinkable Tape:

                This product is manufactured by compositing high-performance hot melt adhesive into a substrate in PE sheet extrusion process, and then by secondary processing after radiation cross-linking. The general thickness is 1.2 to 2.5mm, the tensile strength is generally about 15Mpa, the peel strength is higher than 70N/CM, and the sealing effect is good.


                Performance Features:
                Quick shrink, good water resistance, corrosion resistance, long service life, easy to transport and convenient for construction.
                 

                Scope of Application:

                For PE pipes, it is recommended to connect with tapes of the diameter between Φ200 to Φ1500mm.


                Purpose: 

                Mainly used for heat supply pipe networks, oil pipelines, natural gas pipelines, anti-corrosion and thermal-insulation steel pipes, chemical pipelines, sewage pipelines and other fields.



                Instructions for Use:

                ① Preparations for connection of heat shrinkable tape: gas tank, spray gun, horizontal bar, cleaning cloth and gloves.
                ② Arrange the pipes in a level position, wipe the connection positions with a clean rag.
                ③ Slightly preheat the pipe connection parts to 60°to 80°.
                ④ Wrap the heat shrinkable tape and fix it with a stainless steel fastening strip or fixing plate.
                ⑤ Firstly heat the sealing part with a gas spray gun, after slightly melting, heat a round of the central part of the heat shrinkable tape, and then slowly move downward. (It is better to wrap the fastening strip with a damp cloth, in case that the heat shrinkable tape is pulled open at the fastening strip section, because the thermal conduction of the stainless steel is very quick.)
                ⑥ Inspect the connection status, until there is a small amount of glue overflow on the edges, and reheat the bad parts for a reliable connection.
