Product Description

Oil Gas 3LPE Pipeline Girth Welding Coating Heat Shrink Sleeve

INTRODUCTION 

PE heat shrinkable tape (sleeve) is composed of cross-linked polyethylene back and special heat melt adhesive. Heat melt adhesive has good bonding with PE back, steel pipe and Fusion bonded epoxy (FBE layer). By heating PE back shrinks, adhesive layer melts, and closely wraps around pipe joints, then it forms together with FBE a firm and continuous anti-corrosion body. It is resistant to corrosion, wear, impact, UV and aging,easier to be operated.

Wrap around products
Application area:
It is mainly used for wrapping around pipe, anti-corrosion of kinds of pipe joints, and repairing pipes. 
For example: Oil and gas pipe, PU insulation pipe, 3PE/2PE steel pipe. 

TEST PROCEDURE AND TEST RESULT                              

TEST PROCEDURE

1.  Clean the steel pipe and heat it by fire till over 80 ºC

2.  Paint the steel pipe with Primer (mixed with A&B)

3. Fire heat the heat shrink sleeve, be attention to start heating from middle of the sleeve, but act from up and down, and gradually move from middle to two sides of sleeve, in order to drive air out of the sleeve, after finish heating, the good result is that there is about 1-2mm hot adhesive melt at the edge of sleeve.

TEST RESULT

1. Test result after cooling about 40 minutes.

  Peel strength to primer is over 100N per 2cm(till the end of the spring balance). at 30.7ºC

  Co-adhesive: Half-half.


 

2. Test result after cooling about 24hours. 

  Peel strength to primer is over 172N per 2cm at room temperature about 30.7ºC

  Co-adhesive: Half-half. 
 

Application:

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

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

EVA is imported. Brand Matsui Japan or Dupont USA
The heat shrinkable sleeve has been exported to Vietnam, Sudan, Kenya, Russia, Kazakhstan, Australia, Turkey etc.

Features & Benefits

Heat Shrinkable Sleeves provide great corrosion protection, superior resistance to cathodic disbandment 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.
