Product Description

 Introduction

 LLDPE and HDPE pipes are based on steel pipes and pipe fittings, under a certain temperature, the high performance polyethylene materials will be coated on the inner wall of the steel pipes and pipe fittings, making the combination of plastic and steel matrix, because impoted coated level LLDPE or HDPE as coated plastics make the products with complex force strong, not to take off layer, good anti-corrosion performance, high impact strength, good permeability, rotomolding layer smooth level off, the friction coefficient is small, not easy to scale, in accordance with the convenience and other significant advantages, steel and plastic anti-corrosion steel pipes and pipe fittings can be widely used in the chemical industry, electric power, metallurgy, food, environmental protection and other industries.

 

Features:

1. The excellent physical properties

2. Good corrosion resistance

3. The anti scaling performance is good

4. Choose grade non-toxic plastic products can be used in food, pharmaceutical and other industries

5. Choose the compensation plug-in connector or flexible joints, pipe has the ability to compensate, provide free deflection Angle, easy installation

 

Classification:

Straight pipes, standard elbow, standard tee, standard cross, eccentric pipes.
