End Closure For Plastic Pipes designed to meet EN921 ISO1167 ASTM and GB T standards providing sealing for plastic pipe testing

The DN630mm stainless steel or carbon steel end cover assembly for hydrostatic testing apparatus is engineered to deliver hermetic sealing for plastic pipe specimens including PVC, PE, PP-R, ABS, and composite pipes during hydrostatic tests, bursting tests, negative pressure tests, and other related evaluations.

• Clamp-first, seal-later assembly mechanism with 100% one-time success rate for both clamping and sealing operations
• Radial sealing structure compatible with broad spectrum of pipe materials including PE, PVC, PP-R, and steel-lined composite pipes
• Assembly consists of semi-circular base, silicone rubber O-ring, follower ring, retaining clamp, fastening bolts, compression bolts, and vent valve

This fixture supports pipe specimens with diameters ranging from DN20mm to DN630mm, covering mainstream plastic and composite pipe specifications.

It employs a radial compression sealing mechanism, which ensures reliable hermetic closure for PE, PVC, PP-R and steel-lined composite pipes.

The core structural components are fabricated from high-strength stainless steel or carbon steel, featuring excellent corrosion resistance and pressure-bearing capacity.

The fixture's rated operating pressure reaches up to 16MPa, fully meeting the requirements of hydrostatic tests, bursting tests and negative pressure tests.

It consists of a modular base assembly, high-performance sealing gasket, pressure ring, locking clamp, compression fasteners and exhaust valve, with a detachable and easy-to-maintain structure.
