P.E.S is a pioneer in improving PE welding techniques and technical and engineering support in the field of pipe design, static and hydraulic calculations, welding, installation and commissioning PE systems in Iran.
As the only Iranian company, P.E.S is active in the field of welding PE pipes under the license of SKZ German Plastics Center since 2005. All P.E.S welders participate in welding training courses for welders and welding supervisors under supervision of SKZ. After obtaining an internationally accredited certificate, P.E.S welders execute and supervise installation operation in accordance with SKZ standards and procedures. At customer’s request, P.E.S is able to use SKZ experts in its executive projects as supervisor and consultant.
Providing services to customers relying on 40-year experience in the production and installation of HDPE pipes utilizing experienced and trained technicians with an accredited certificate from the German SKZ Institute, P.E.S meets all of your needs regarding HDPE piping and installation.
Butt fusion of PE pipes is a cost-effective, fast and reliable method for joining and installing PE pipe systems, because weldments are very strong, flexible and leak-free like the pipe.
Butt fusion is the best choice and common method for joining PE pipes. In this method, joining surfaces (the pipe wall thickness) are heated by a hot plate up to welding temperature. The hot plate is then removed and melt surfaces are pressed for a certain time to complete welding operation.
For electrofusion of socket fittings, thermal coils are used to generate heat and join the pipes. In this method, a thin layer of the external surface of the pipe is involved in electrofusion connection. This limits application of this welding method.
In both methods, welding quality is dependent on welding machine, welder experience and skill, optimal use of welding machinery and equipment and welding procedures. A welder should participate in welding courses to receive an updated accredited certificate.
P.E.S welding manual has been prepared according to German Welding Society manual, DVS 2207-part 1.
