Given that polyethylene pipes are manufactured in 6- and 12-meter branches, and screw and O-ring fittings have high installation costs and low strength, PE welding machines were designed and built to speed up the work and enhance the installation quality of pipes and fittings. Our PE welding machines are produced based on ISO 12176-1, DVS 2201. After production stage, PE welding machines go through testing, experimentation and calibration stages.
