PVC drainage pipe production line adopts special desgin for extruder screw, which ensures high productivity and good product quality. Material of screw is 38CrMoALA, with high quality alloy steel coating and nitriding treatment, which increases resistence against abrasion and corrosion, and ensures service life of machine. PVC drainage pipe line adopts air cooling for heating zone, which is faster for temperature adjusting. The finished pipe product has the advantages of high ring-stiffness, low weight, easy installation, etc, and has been widely applied in building construction, watering, and cable conducting projects.

Comparing with PVC pipe, PE pipe has no toxic content in formula additive, no incrustation after long term use, no bacteria breeding. Therefore, it corresponds to the sanitary requirements under national standard GB/T17219.

PE water supply pipe has good resistence against corrosion from many kinds of chemical medias. It also resists electrochemistry corrosion.

Inner surface of PE water supply pipe is smooth, with low friction index, which increases fluid flowability and abrasion resistence inside the pipe.

Other features: good flexibility, high impact strength, strong shock resistence, distortion resistence, low weight, easy transportation and installation.

PVC pipe is mainly used in building construction piping system for water supply, water drainage, air exhaust, sanitary pollution discharge, underground water drainage, storm sewer, and electric cable conduit.
