What's the End cap of pipe pressure test? 

Understand the pipe end cap for hydrostatic pressure test: 

The hydrostatic pressure test end cap is specialized equipment used to detect the pressure-resistant performance of pipes, primarily used for static hydraulic tests and burst tests of plastic pipes (such as PVC, PE, PPR, etc.). It conducts pressure testing by sealing the ends of the pipes to assess their long-term static hydraulic strength and pressure resistance. 

Core Functions:

Sealing Test: Achieved through silicone sealing rings and radial sealing design, firmly sealing the ends of the pipes to prevent liquid leakage during testing.

Specification Compatibility: Supports various diameters (such as Φ16-Φ1600mm), suitable for testing the requirements of different materials such as PVC, PE, PPR, and composite pipes.

Compliance with Standards: Adheres to national standards such as GB/T 6111 and GB/T 15560, as well as international standards like ISO 1167.

Main Structural Features of UnitedTest end cap:

Material: Typically made of 304 stainless steel, which is corrosion-resistant and has high strength.

Design: The split structure facilitates installation, achieving a sealing rate of 100%, and supports quick disassembly and assembly.

Stainless Steel End Caps For Pipe Hydrostatic Pressure and Burst Testing  are designed for internal hydrostatic pressure testing of pipes and fittings. It is used to seal the sample in order to generate internal pressure in the sample, with the characters: ISO 1167 Type A structure, External type: for diameter 16mm till 2000mm, three to six petals structure(not welding), no leakage under high pressure, Nickle coating, reliable and durable, 100% success installation.

The end caps without connecting rods are used for PE, PVC, and PP pipes. The depth of the end cap from the O-ring to the internal bottom is specific, ensuring that the cap is tight when pressure is applied to the edges and oval PE pipes. The UnitedTest end cap complies with ASTM D 1598, ASTM D 1599, and ISO 1167 standards.
