Heat shrink sleeve for girth welding pipe
Heat shrinkable sleeves for girth welding pipe are the most widely used technology in the world for field girth-weld corrosion protection. Because they are easy to install, provide excellent protection and are cost-effective.With formula made of various raw materials and radiation,cross linking and other process techniques, heat shrinkable wrap sleeve with various size for various purpose are manufactured. They are widely used in joint corrosion prevention, leakage prevention, protection of petroleum, natrual gas and heat insulation pipelines, etc. Heat shrinkable sleeves for girth welding pipe are predominant in high mechnical strength, strong anti-aging capability, good sealing property, corrosion resistance, convenient construction, etc.
