End Closure For Plastic Pipes With Hold Clamp Compression Bolts And Vent Valve For Secure Sealing In Pressure Equipment
Usage:
The DN710mm stainless steel end cover components for hydrostatic pressure equipment are specifically designed to seal non-metallic piping materials—including PVC, PE, PP-R, ABS, and composite pipe specimens—during hydrostatic pressure tests, burst tests, negative pressure tests, and other relevant testing procedures.
Features:
This structure adopts a clamp-before-seal assembly mechanism, boasting a 100% one-time clamping and sealing success rate.
Featuring a split-type clamping structure, it facilitates easy installation and enables automatic centering. Large-diameter clamps deliver broad compatibility with various pipe diameters.
Radial sealing technology is adopted, ensuring wide applicability to diverse pipe types, including PE, PVC, PP-R, steel-lined composite pipes, and more.
The unit is composed of a semicircular base, silicone rubber O-rings, a follower ring, clamping jaws, fastening bolts, compression bolts, and a vent valve.
Other models:
Applicable pipe diameters for the equipment include Φ8mm, Φ10mm, Φ16mm, Φ25mm, Φ32mm, Φ40mm, Φ50mm, Φ63mm, Φ75mm, Φ90mm, Φ110mm, Φ125mm, Φ140mm, Φ160mm, Φ180mm, Φ200mm, Φ225mm, Φ250mm, Φ280mm, Φ315mm, Φ355mm, Φ450mm, Φ500mm, Φ560mm, Φ630mm, Φ710mm, Φ800mm, Φ900mm, Φ1000mm, Φ1100mm, Φ1200mm, Φ1400mm, Φ1600mm, Φ1800mm, and other matching specifications.
