Product Description:
PE Oil Gas Pipeline Field Joint Corrosion Protection Coating Heat Shrinkable Sleeve
INTRODUCTION
The Heat-Shrinkable Sleeve is composed of cross-linked polyethylene back and special heat melt adhesive. The heat melt adhesive has good bonding with PE back, steel pipe and Fusion bonded epoxy (FBE layer). When heating the sleeves, the PE back shrinks, the adhesive layer melts and closely wraps around pipe joints. It can form together with FBE a firm and continuous anti-corrosion body. It is resistant to corrosion, wear, impact, UV and aging, and is easy to be applied.
Our company has been working on this product for 18 years. We use high-quality raw materials for the production of Heat Shrink Sleeves, which can provide superior corrosion protection for the pipeline joints.
APPLICATION AREAS
The Heat-Shrinkable Sleeve is mainly used for pipeline corrosion protection, sealing and corrosion protection of pipeline joints, pipes repairing. For example Oil and gas pipelines, Pre-insulated pipes, water transmission pipelines.
Executive Standard
Products comply with national and international standards GB/T23257-2009, SY/T4054-2003, EN12068, DIN30672 etc.
Heat shrinkable sleeve for the pipeline, developed and manufactured by Qingdao Huashida Machinery Co., Ltd, is composed of cross-linked polyethylene backing and special heat melt adhesive. On the basis of the 2-layer heat shrinkable sleeve, we have developed a 3-layer structure by adding a glass fiber net between the backing and adhesive, which gives stronger tensile strength and shrinkage. It is resistant to corrosion, wear, impact, UV and aging, easy to be installed.
Application:
Heat shrinkable sleeve/belt is suitable for steel pipe anti-corrosion coating, field joint corrosion protection of steel pipe with 3-layer or 2-layer polyethylene anti-corrosion coating, pre-insulated pipe sealing and HDPE drainage pipeline, sewer pipeline jointing.
