The special construct of three lays and steel wire can be adapted to dirrerent pressures by regulating the paramenters of the middle layer. Temperature for using is below +40 and the pressure is 1.0-3.5Mpa. performances: antistatic, fireproofing, wear-resistant,pressure-resistant,light,tough

The three-layer steel wire strengthened PE pipes are used in the mine for water supply and drainage,air with positive pressure,and for gas.this kind of pipe resistant,fire proofing,wear-resistant,corrosion resistant,light,reliable and easy to install.By the way of regulating the raw material ,the pipes can be used for different purposes in the mine.
