End Closure For Plastic Pipes Pressure Test End Caps
Manufactured from stainless steel and carbon steel with durable nickel coating, these end closures provide reliable sealing solutions for pipeline hydrostatic test fixtures.
Product Overview
- Annual production capacity of tens of thousands ensures technical maturity and stable product quality
- Available in 45# carbon steel or 304# stainless steel raw materials
- Multiple configurations including end seal, external seal, and double seal types
- Compatible with pipes of various diameter specifications
End Seal Type
Designed for pipes with diameter less than 315mm, featuring triple-cap weld-free structure. Provides zero leakage under high-pressure conditions, nickel-plated surface, easy installation, superior sealing performance, and excellent long-term durability.
External Seal Type
Suitable for pipes with diameter ranging from 250mm to 2000mm, featuring four-to-six-cap weld-free structure. Maintains reliable leak-tightness under high pressure, nickel plating for corrosion resistance, stable and durable operation, and 100% installation success rate.

Frequently Asked Questions
Q1: What is the tolerance range of the raw material size for the pipe hydrostatic clamp end closure?
A1: The raw material (45# carbon steel or 304# stainless steel) of the end closure features a size tolerance of ±0.02mm, which ensures structural precision and avoids fitting errors during installation.
Q2: What is the thickness of the nickel plating on the surface of the pipe hydrostatic clamp?
A2: The nickel plating thickness on the clamp surface is controlled at 8-12μm, which effectively enhances corrosion resistance and prolongs service life in harsh test environments.
Q3: What is the maximum pressure that the pipe hydrostatic clamp can withstand without leakage?
A3: Regardless of end seal or external seal type, the clamp can withstand a maximum hydrostatic pressure of 30MPa without leakage, meeting high-pressure test requirements of various pipes.
Q4: What is the fitting tolerance between the pipe hydrostatic clamp and the tested pipe?
A4: The fitting tolerance between the clamp and the tested pipe is ≤0.1mm, which ensures tight connection, prevents pressure leakage, and guarantees test result accuracy.
Q5: What material is used for the sealing gasket of the pipe hydrostatic clamp?
A5: The sealing gasket uses high-temperature and high-pressure resistant fluorine rubber material, providing good elasticity and wear resistance for long-term test work under different temperature conditions.
Q6: What is the service life of the pipe hydrostatic clamp under normal use conditions?
A6: Under normal laboratory or factory test conditions, the service life reaches more than 8 years, thanks to high-quality raw materials and mature manufacturing processes.
