Product Description

Heat Shrinkable Sleeve for Mrp Pipe Joint Heat Shrink Wrapper


Radiation cross-linked Polyethylene (PE) Heat Shrinkable Sleeve is mainly used in anti-corrosion, repairing of oil gas pipeline,is fit for 3PE oil gas steel pipe, 2PE steel pipe, thermal insulating pipe, Epoxy powder coating, and PE drainage pipe etc. We have National Patent certifications.

Radiation crosslinked PE heat shrinkable sleeve is made by basic material and melt adhesive. Our product is with strong adhesion to make sure good quality of project; easier operation, quick shrinking, low cost, perfect anti-water permeating, anti-chemical corrosion, good insulativity and aging resistance, is ideal material of anti-corrosion and thermal insulating system.

EVA is imported. Brand Matsui Japan or Dupont USA
We sold it to Vietnam,Sudan, Kenya, Russia, Kazakhstan,Australia, Turkey etc.

Specifications
---3 Layer PE Coating Pipe
---Offeshore &Underground
---Oil, Gas,Water pipeline
---DIA2''-72''
---Pipeline size: from Ø 108 to Ø 1554 ( 4''---60'')
Sleeves width: 100mm, 150mm,200mm, 300mm,450mm,500mm,600mm,900mm
Closure patch: 100mm, 150mm,200mm (4'', 6'', 8'')

Product Structure
The inner layer is two-components epoxy primer which coated on steel pipe;
Intermediate level is special hot melt adhesive;
Outer layer is modified radiation crossing linking polyethylene backing.

Heat Shrinkable Sleeves provide great corrosion protection, Superior resistance to Cathodic Disbondment and excellent durability against abrasion and chemical attack. The result is effective, good performance of sealing, wide application, easy to operate and preheating temperature low (50 °C) ,long term protection against corrosion.
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.
