End Closure For Plastic Pipes With Hold Clamp Compression Bolts And Vent Valve For Secure Sealing In Pressure Equipment

This stainless steel end closure is designed for secure sealing of plastic pipes in pressure testing equipment, featuring hold clamp compression bolts and a vent valve for reliable performance in hydrostatic pressure tests.

The DN710mm stainless steel end cover components 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.

• Clamp-before-seal assembly mechanism with 100% one-time clamping and sealing success rate
• Split-type clamping structure for easy installation and automatic centering
• Large-diameter clamps with broad compatibility for various pipe diameters
• Radial sealing technology ensuring wide applicability to diverse pipe types
• Comprehensive component system including semicircular base, silicone rubber O-rings, follower ring, clamping jaws, fastening bolts, compression bolts, and vent valve

Applicable pipe diameters 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.

Manufactured and commissioned in strict accordance with international and domestic testing specifications including EN 921, ISO 1167, ASTM D1598, ASTM D1599, GB/T 6111, GB/T 15560 and other applicable standard protocols.

A1: It is compatible with all mainstream plastic piping products, such as thermoplastic pipes, modified engineering plastic pipes and polymer composite plastic pipes.

A2: It adopts circumferential differential sealing configuration, which forms a closed pressure boundary without damage to the conduit surface.

A3: The core load-bearing structural components are manufactured with high-quality stainless steel and carbon steel, delivering exceptional structural stiffness and working durability.

A4: It relies on the arc-shaped guide slots to realize passive self-alignment, keeping the conduit axis consistent with the pressure channel axis.

A5: Corresponding fixture dimensional options are supplied in full accordance with the outer diameter specifications of various pipes, covering all standard pipe sizes with dedicated and matched fixture models.

A6: It is applicable for long-term static pressure verification, instantaneous rupture evaluation and negative pressure tightness assessment of tubing products.
