Gas fitting USTR

screw-inPEsteel

Transition fitting, steel pipe USTR Material; PE 100 and steel [EN 10220 / EN 10216-1 - P235TR2] Safety technology Note: Anchored the steel side non-detachable and non-rotatable in the PE. Self-sealing, patented sealing geometry without elastomeric gasket for use in gas applications. Steel pipe batch characterised by re-stamping of the pipe connection. Areas of Application FRIALEN-Transition Fittings USTR are used for connection of HD-PE house connection pipe to the steel pipe of the house entry fitting. The larger dimensions connect an HD-PE pipeline to a steel fitting or steel pipeline. Assembly Instructions Due to heat dissipation only arc welding is permissible. The fusion of the HD-PE side takes place by FRIALEN-fusing – leakproof and longitudinally strong. Welding of the steel end and fusion of the HD-PE side have to be prepared according to the general installation instructions (see ”Transition Fittings” in ”Assembly Instructions” for ”FRIALEN-Safety Fittings for house connections and distribution pipes up to d 225”). This involves removing the oxide skin and cleaning the pipe ends. Good reasons for using the FRIALEN-USTR: Compact construction HD-PE side with exposed heating element for optimal heat transfer Cold zones at the end to prevent the flow of molten material No holding clamps required Large insertion depth, extra wide fusion zones Steel end permanently anchored in the HD-PE and will not distort Self sealing patented sealing geometry without elastomer seal Additional barcode for tracing back the underground fitting (Traceability-Coding)
