End Closure For Plastic Pipes
Manufactured to comply with EN921, ISO1167, ASTM D1598 and ASTM D1599 standards for industrial applications.
Product Overview
As a key accessory for pipe testing, the DN560mm seal joint—available in stainless steel (SS) or carbon steel—is professionally designed and manufactured with precision. It is engineered for sealing HDPE, PE and PVC pipes, and is compatible with various plastic pipe and composite pipe specimens including PVC, PE, PP-R, ABS and composite pipes. This joint provides reliable sealing for multiple testing scenarios, including hydrostatic test, bursting test, negative pressure test and other related pressure-based tests.
Structural Features
The Casting Type-A Structural Fixture adopts a design without intermediate tie rods, boasting exceptional high-pressure resistance. It is composed of:
- Semicircular base
- Silicone rubber O-ring
- Follower ring
- Holding clamp
- Fastening bolts
- Compression bolts
- Vent valve
All components are precision-machined for reliable performance in pipe testing.
Available Models
The seal joints and structural fixtures are compatible with a wide range of pipe diameters, including: φ10, 12, 16, 25, 32, 40, 50, 63, 75, 90, 110, 125, 140, 160, 180, 200, 225, 250, 280, 315, 355, 400, 450, 500, 560, 630, 710, 800, 900, 1000, 1100, 1200, 1400, 1600, 1800 and 2000mm. They also support British standard, American standard and other international pipe specifications to meet diverse testing needs.

Frequently Asked Questions
Q1: What pipe materials are compatible with this hydrostatic fixture?
A1: It is well-suited for clamping thermoplastic pipes, composite pipes and rigid plastic pipes, including HDPE, PE, PVC, PP-R, ABS and other analogous pipe materials.
Q2: What is the maximum pressure-bearing capacity of the fixture?
A2: Thanks to its tie-rod-free casting structure, the fixture can withstand ultra-high pressure, fully matching the 0-10MPa test demand of hydrostatic and bursting tests.
Q3: Does the fixture support precise adjustment for different pipe diameters?
A3: Yes, it is compatible with pipe diameters ranging from φ10mm to φ2000mm, and can be fine-tuned via fastening bolts and compression bolts for tight clamping.
Q4: What material is the sealing component of the fixture and its service life?
A4: The sealing part adopts a silicone rubber O-ring, which features good pressure resistance and corrosion resistance, with a normal service life of 800-1000 test cycles.
Q5: Is special tooling required for fixture installation and disassembly?
A5: No special tooling is needed. It can be quickly installed and disassembled by operating the integrated fastening bolts, improving test efficiency.
Q6: Which hydrostatic test standards does the fixture comply with?
A6: It conforms to international standards such as ISO 1167, ASTM D1598 and GB/T 6111-2018, ensuring consistency with mainstream pipe test requirements.
