HDPE Pipe for Drawing Out Methane

HDPE Pipe for Drawing Out Methane

Tengyuan 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 MT588.1-2005 (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.

Looking for HDPE mining tailing pipe, HDPE Pipe for Drawing Out Methane, Mining Pipe and HDPE steel mesh reinforced pipe? We views innovation as the driving force of sustainable development and creates value for society, customers, shareholders, employees.
