End Closure For Plastic Pipes
Product Overview
End closure for plastic pipes featuring base clamp, sealing pressure plate, and fastening screws designed for internal pressure resistance during hydrostatic testing.
Intended Use
Designed to deliver reliable sealing for plastic piping specimens during hydrostatic pressure and burst testing, in full accordance with ISO 1167, ASTM D1598 and ASTM D1599 standards.
Construction
The end cap assembly consists of a support base, silicone sealing ring, connecting bolts, sealing platen and fastening jig.
Fastening screws are configured for the sealing platen. A medium overload protection structure is reserved in the mounting hole of the clamp base, and the inner side of the clamping jaw is precision-machined for the fastening jig.
