This product is suitable for the manufacture and inspection of high performance hard PVC pipes and ﬁttings for water supply in outdoor burial ground and pipe gallery where the water temperature is not more than 45 °C.
High performance hard PVC pipe
PVC pipe with minimum required strength (MRS) greater than or equal to 2.5 MPa is used as raw material, which is extruded into shape and has an integral steel framework sealing ring ring structure, referred to as "pvc-uh pipe".
Copper skeleton seal ring
Sealing ring with strip steel skeleton lining for PVC-UH pipes.
Note: Steel skeleton seal ﬂaring embedded at the same time expanding the pipe mouth, ﬂaring prefabricated directly by the sealing ring grooves structure forming, ﬂaring, after the completion of form into a type of steel skeleton seal socket structure. The damage cases, bearing the mouth of the sealing ring out.
