Compact transition fitting. HD-PE end with exposed heating coils for optimal heat transfer, large insertion depth, wide fusion zone plus cold zones at the end and in the transition area to prevent the flow of molten material, for use without holding devices. Steel end permanently anchored in the HD-PE. Self sealing patented sealing geometry without elastomer seal. For use in gas systems. Steel pipe sockets marked by restrutting (for use with gas up to 10 bar).

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
