Product Description
End Closure For Plastic Pipes With O-Ring Seal and Clamp Mechanism
Factory-direct DN90mm 304 Stainless Steel Pipe Fitting End Closures are specifically engineered for sealing test pipes made of PVC, PP, and PE materials during pressure testing applications.
Working Principle
High-temperature resistant silicone sealing rings are embedded in the seal grooves of the end caps. The metal rings integrated with the end caps apply compression to the silicone sealing rings, creating a secure seal through deformation induced by external pressure.
Construction
This end closure comprises a base, sealing ring, pressing ring, and clamp, forming an integrated sealing structure specifically designed for pipe testing applications.
Application
Primarily intended for sealing PVC, PE, PP-R, ABS, and composite pipe specimens during hydrostatic testing, bursting tests, negative pressure tests, and other relevant pipe testing scenarios.
Fixture Structure
Adopting a semicircular pot structure, this end closure features easy installation, leak-proof performance, and user-friendly operation. Available in various diameter specifications to meet specific testing requirements, with the main body crafted from 304 stainless steel or carbon steel.
Standards Compliance
Executive standards: ISO1167, ASTM D 1598/1599
Available Models
Available diameter specifications include:
- Metric sizes: φ10, 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

Frequently Asked Questions
Q1: What is the temperature adaptability range of the fixture's sealing component?
A1: The built-in silicone sealing ring features high-temperature resistance, adapting to a working temperature range of -20℃ to 120℃, which meets most pipe hydrostatic test conditions.
Q2: How does the fixture ensure long-term leak-proof performance?
A2: The metal pressing ring exerts uniform pressure on the silicone ring, and the integrated clamp structure maintains stable compression, avoiding seal failure caused by pressure fluctuation.
Q3: Is the fixture compatible with both metric and ASTM standard pipes?
A3: Yes, it supports full-range metric diameters from φ10mm to φ2000mm and all listed ASTM standard sizes, realizing universal application for different specification pipes.
Q4: What is the service life of the fixture's main structural parts?
A4: Made of 304 stainless steel or carbon steel, the base and metal rings have strong corrosion resistance, with a service life of over 5 years under regular test frequency.
Q5: Can the fixture be quickly switched for pipes of different diameters?
A5: It adopts a modular design, allowing fast replacement of matching sealing rings and pressing rings, reducing diameter switching time to within 5 minutes.
Q6: Does the fixture require regular maintenance for sealing performance?
A6: Routine maintenance only involves checking the silicone ring for wear every 300 test cycles; replacement is simple and quick, without affecting overall test efficiency.
