HDPE Pipe for Drawing Out Methane

RTF HDPE mining pipes are made of special polyethylene-based raw materials with flame. retardant and anti-static properties And all of the pipes are produced by advanced production equipments through extruding technique at high temperature. We arrange production and inspection in accordance with national coal industry standard MT5881-2005( the first part of plastic mining pipe: PE pipe),MT181-88 safety inspection specification of plastic mining pipes"and AQ1071-2009"safety technical requirements for non-metallic gas transmission mining pipe". We obtain the coal mine safety signs(MA)for polyethylene mining pipes.

Description

Application:

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