Heavy Duty End Closure For Plastic Pipes Equipped with Silicone Rubber Seal and Vent Valve for Hydrostatic Testing Performance
Equipped with silicone rubber seals, these DN500mm end caps for hydrostatic testing are engineered and fabricated specifically to deliver reliable airtight sealing for PVC, PE, PP-R, ABS, and composite pipe specimens. They are fully compatible with a comprehensive range of pressure performance evaluations, including hydrostatic pressure tests, bursting strength tests, and negative pressure tests.
Applications
Designed for PVC, PE, PP-R, ABS, and composite pipe specimens in hydrostatic pressure tests, bursting strength tests, and negative pressure tests.
Structural Features
This Casting A-type structural fixture eliminates intermediate tie rods in its design, boasting exceptional pressure resistance to withstand high-intensity testing conditions.
It comprises a full suite of precision-engineered components, including a semi-circular base, a silicone rubber O-ring, a follower ring, a holding clamp, fastening bolts, compression bolts, and a vent valve, all of which work in synergy to ensure stable sealing performance during high-pressure tests.
Meets the following standards: GB/T 6111, GB/T 18252, GB/T 15560, GB/T 18997.1, EN921, ISO1167, ASTM D 1598/1599.

Frequently Asked Questions
Q1: What material is adopted for the main body of the pipe hydrostatic testing fixture, and how does it perform in corrosive test environments?
A1: The fixture's main body is forged from high-strength carbon steel with anti-corrosive electroplating treatment on the surface. This design enables it to resist corrosion from water-based testing media and mild chemical solutions, ensuring a long service life even under frequent cyclic testing conditions.
Q2: How often should the sealing components of the hydrostatic fixture be replaced, and is the replacement process user-friendly?
A2: Under normal operating conditions, the silicone rubber sealing rings of the fixture require replacement every 6-8 months, depending on the frequency of use. The replacement process is tool-free; users only need to detach the pressure ring, take out the old seal, and fit the new one--no professional technical support is needed.
Q3: What range of pipe wall thicknesses can the hydrostatic testing fixture accommodate without affecting sealing performance?
A3: The fixture is adjustable to match pipe wall thicknesses ranging from 2 mm to 25 mm. Its flexible compression bolt system can compensate for minor thickness variations, maintaining a tight, leak-free seal for both thin-walled corrugated pipes and thick-walled pressure pipes.
Q4: Does the hydrostatic fixture feature a quick-connect structure, and how does it improve testing efficiency?
A4: Yes, the fixture is equipped with a snap-fit quick-connect structure. Unlike traditional bolt-fastened fixtures that take 5-8 minutes for installation, this design allows users to secure pipe specimens in 1-2 minutes, significantly reducing the downtime between consecutive tests.
Q5: What is the recommended method and frequency for calibrating the clamping force of the hydrostatic fixture?
A5: The clamping force of the fixture should be calibrated using a digital torque wrench every 3 months. The calibration process involves tightening the compression bolts to the specified torque value and verifying the clamping force with a pressure sensor, ensuring the fixture meets the clamping force requirements specified in ISO 1167 standards.
