91 Pipe fittings Loose flanges, SF flanges, HP flanges Flange joints are typically used to connect the pipe system to valves, pumps and other pipes. Extena supplies a wide range of flange joints such as loose flanges, SF flanges and HP flanges with different pressure classes and drill holes. The collars are made of polyethylene and are extended for optimal welding conditions. Products are available in dimensions from 63 mm up to 1200 mm. Arc welding parts made of PE100 RC Extena supplies a wide range of arc welding pipe fittings for jointing PE pipes. Our arc welding components represent high quality and reliability aimed at providing our clients with safe and efficient operation. Remember that for optimal welding results you will require tight tolerances between the pipe and pipe fitting, and problems often arise in larger dimensions when using pipes with a high degree of ovality. Thanks to our manufacturing process, Extena has been able to set higher requirements and significantly tighter tolerance levels for ovality than the standard allows. Extena arc welding parts are made of PE100 and PE100 RC according to ISO 11922. First class production ensures safe and efficient installations. Arc welding parts Flange joints
