Anticorrosion heat shrink sleeve
- BrandDEEM
- TypeDM-HT
Mainly used for joint coating, damage repair of steel pipelines in petroleum, natural gas, chemical industry, urban gas pipeline networks, etc., as well as joint sealing and fixing of PE and PVC pipelines in engineering projects such as externally wrapped anti-corrosion and thermal insulation pipelines (clamped pipes) for joints, elbows, tees, and water supply and drainage.
Features
High mechanical strength, strong anti-aging ability, good sealing performance, corrosion resistance, convenient and fast construction, time and labor saving.
Notes
Materials can be customized according to different temperatures and regions.
