High Pressure Resistant Plastic Pipe End Caps
High pressure resistant Plastic Pipe End Caps ideal for sealing plastic pipes during hydrostatic and bursting tests.
Product Overview
The DN560mm Sealing Joint, available in Stainless Steel (SS) or Carbon Steel options, is purpose-engineered and precision-fabricated to deliver reliable sealing for plastic and composite pipe specimens during critical performance tests. It is specifically compatible with HDPE, PE, PVC, PP-R, ABS, and composite pipes, facilitating leak-tight sealing for hydrostatic testing, burst testing, negative pressure testing, and other related pipe performance evaluations.
Structural Features
The Casted Type-A Structural Fixture features a rodless design (devoid of intermediate tie rods) and exhibits exceptional high-pressure resistance, making it suitable for rigorous pipe testing scenarios involving extreme pressure loads.
Its component configuration comprises a semi-circular base, a silicone rubber O-ring, a follower ring, a clamping block, fastening bolts, compression bolts, and a vent valve—all engineered to work in synergy for reliable sealing and structural stability during testing.

Frequently Asked Questions
Q1: What materials are used in the manufacturing of the pipe fixture, and what corrosion resistance performance does it offer?
The pipe fixture is constructed from high-grade stainless steel (SS) or carbon steel, with all media-contacting surfaces featuring anti-corrosion treatment. This design ensures excellent resistance to chemical erosion and moisture, making it suitable for long-term use in hydrostatic, bursting, and negative pressure testing environments involving various pipe materials.
Q2: What is the applicable pipe diameter range of the fixture, and which international standards is it compatible with?
The fixture covers a wide diameter range from Ø10 mm to Ø2000 mm, including key specifications such as Ø50 mm, Ø110 mm, Ø315 mm, Ø630 mm, and Ø1600 mm. It is fully compatible with international standards including British Standards (BS), American Standards (ASTM/ASME), and ISO series, seamlessly adapting to global pipe production and testing requirements.
Q3: What is the maximum pressure-bearing capacity of the pipe fixture, and can it meet high-pressure testing demands?
The fixture boasts a maximum pressure-bearing capacity of up to 16 MPa (160 bar), which fully meets the pressure requirements of hydrostatic testing and bursting testing for most industrial plastic pipes (HDPE, PE, PVC, composite pipes, etc.). Its rodless structural design enhances pressure resistance stability, avoiding leakage or deformation under extreme pressure conditions.
Q4: What sealing mechanism does the fixture adopt, and how does it ensure leak-tight performance during testing?
The fixture utilizes a silicone rubber O-ring sealing system combined with a follower ring and clamping block design. The O-ring provides elastic sealing that closely fits the pipe inner wall, while the clamping block and compression bolts achieve uniform pressure application. This multi-layer sealing structure ensures zero leakage during testing, even under prolonged constant pressure.
Q5: What structural features does the fixture have to simplify installation and improve testing efficiency?
The fixture adopts a casted Type-A structural design without intermediate tie rods, featuring a compact and lightweight structure. It is equipped with standardized fastening bolts and compression bolts for quick assembly and disassembly—reducing pipe clamping time by 30% compared to traditional fixtures. The semi-circular base design also ensures stable positioning of the pipe specimen during testing.
Q6: Is the fixture compatible with different types of pipe materials and testing scenarios?
Yes, the fixture is universally compatible with plastic pipes (HDPE, PE, PVC, PP-R, ABS), composite pipes, and steel-reinforced polyethylene pipes. It is suitable for multiple testing scenarios including hydrostatic pressure testing, bursting strength testing, negative pressure tightness testing, and short-term pressure resistance testing, serving as a versatile accessory for pipe testing equipment.
