TSD Heat Shrinkable Tape

 

 

 

 

TSD Heat shrinkable sleeves are the most widely used technology in the world today 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. They are predominant in high mechnical strength,strong anti-aging capability, good sealing property, corrosion resistance, convenient construction,  etc.

 

TSD wraparound heat shrinkable sleeve (HSS) with a separate closure patch is mainly used for field joint coating of underground 3LPE coated steel pipelines and thermal insulated pipelines.

TSD heat shrink sleeve bonds the steel substrate, FBE primer and plant-applied polyethylene coatings excellently to form a continuous and durable corrosion protection system on the pipeline.

 

The Advantages:

• Cross-linked backing provides superior abrasion, mechanical and chemical attack resistance.


• High performance adhesive provides excellent resistance to Cathodic   Disbondment to ensure long-term corrosion protection.


• Just-in-time customized lengths allow bulk rolls to be field cut to protect any pipe size


• Open sleeve configuration allows the product to be applied after the pipeline has been welded and cleaned.
