Heavy Duty End Closure For Plastic Pipes Equipped with Silicone Rubber Seal and Vent Valve for Hydrostatic Testing Performance
Apply to:
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.
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.
And other models:
Other models include:φ8, φ10, φ16, φ25, φ32, φ40, φ50, φ63, φ75, φ90, φ110, φ125, φ140, φ160, φ180, φ200, φ225, φ250, φ280, φ315, φ355, φ450, φ500, φ560, φ630, φ710mm, etc.

FAQ:
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.
