RSCY Heat Shrinkalbe Sleeve For Directional Drilling

RSCY heat shrinkable sleeve provides effective protection against abrasion and wear forces during the pull-through operation

RSCY

Directional Drilling Kit

 Multi-layer Heat Shrinkable Sleeve System for Directional Drilling

1.       Description

Construction: Three-layer system

First layer: Liquid epoxy, solvent-free two-component

Second layer: High shear strength copolymer adhesive

Third layer: Radiation cross-linked, high density polyethylene with or without fibre re-inforced composite structure

Additional component: Wear Cone as extra protection against pull-through forces, of the same construction as the main sleeve.

The RSCY system provides effective protection against abrasion and wear forces that occur during the pull-through operation. The system is fully compatible with cathodic protection systems, resists cathodic disbondment and is designed for a wide range of operating temperatures.

2.       Features

---Highly resistant to shear and peel forces induced by soil and thermal movements

---Superior cathodic disbondment and hot water immersion resistance

---Superior abrasion resistance

---Excellent adhesion performance

3.      Application

---Oil & gas pipelines for directional drilling

---Water pipelines for directional drilling

---Compatible line coating: PE, FBE, Coal Tar

---Pipe size: 50.8mm~1524mm(2"~6")

---Operating temperature range: up to 80oC
