PRODUCT DESCRIPTION

Introduction

Winbel HDPE mining pipes are made of special polyethylene-based raw materials with flame-retardant and anti-static properties. And all of the popes are produced by advanced production equipments through extruding technique at high temperature.

We arrange production and inspection in accordance with national coal industry standard MT588.1-2005(the first part of plastic mining pipe: PE pipe), MT181-88 "safety inspection specification of plastic mining pipes" abd AQ1071-2009 "safety technical requirements for non-metallic gas transmission mining pipe". We obtain the coal mine safety sings (MA) for polyethylene mining pipes.


Application

The products are widely used as coal mine's water supply and drainage pipe, mining positive and negative pressure ventilation pipe, mining spray pope, mining gas drainage pipe and so on.
