Having a vast experience our company produces high quality heat shrinkable sleeves or so called tubes for repairing pipes sections and coating of pipes welded joints, cases   and equipment for manual and automatic coating by means of heat shrinkable and another cold applied tapes. Heat shrinkable sleeves/tapes are widely used in repairing of pipes areas, wrapping around uncoated pipes joints with outer diameter  57…1420mm. under conditions of underground and aboveground laying. For example, the tape is used for oil-gas-water pipelines and other drainage pipeline systems. Moreover heat shrinkable tape considered to be indispensible 2PE/3PE coating material for such pipe fittings as: elbows/bends, crosses, tees, reducers, caps etc. Due to high shrinkable characteristics of the tape it is mostly suitable for curved surfaces as pipe fittings. Operation conditions-40°С up to +70°С. Standard shinkable sveeles thicness is 2.0mm., 2.5mm., 3.0mm., 3.5mm.
