HUASHIDA HDPE Corrosion Resistant Waterproof Heat Shrinkable Sleeve for Pipeline Joints EN253 Certified

Product Description

HUASHIDA HDPE Corrugated Pipeline Joint Heat Shrink Sleeve

Corrosion resistant, waterproof, EN253 certified heat shrinkable sleeve for pre-insulation pipe joints.

Product Introduction

Developed and manufactured by Qingdao Huashida Plastic Co., Ltd., these heat shrinkable tubes are designed for pipeline anti-corrosion applications including oil & gas steel pipelines and metal reinforced HDPE corrugated pipelines.

Our company provides both heat shrinkable sleeves and heat shrinkable sleeve equipment.

The HSS (Heat Shrink Sleeve) is composed of radiation cross-linked polyethylene backing and high shearing strength adhesive.

Application Areas

Oil and gas pipelines
Inspection wells and drainage pipes (metal reinforced PE spiral pipe, hollow wall spiral pipe, etc.)
Thermo insulated pipes
3PE/2PE steel pipes
Pipe joint wrapping and anti-corrosion
Pipe repair applications
