ISO 1167 Pipe Hydrostatic Pressure Tester

HYD-B series Pipe hydrostatic pressure testing machine, Computer + LCD meter both way control.

HYD-B series Pipe hydrostatic pressure testing machine is designed according to ISO 1167, ASTM D1598, ASTM D1599. It's mainly used to test the plastic pipeline, compound pipeline, such as PP-R, PP-B, PP-A, PVC, PE, PE-X etc. Under a stipulated constant hydrostatic pressure force, keeping provision time; or inside the pipe, apply a constant and rapid hydraulic pressure to make the specimen broken in a short period time, check the max. pressure force, then calculate the ring stress. This tester is necessary equipment for plastic pipe manufacturer.

General introduction

UnitedTest Pipe hydrostatic testing machine is primarily used to simulate the pressure conditions that plastic pipes experience in actual use. By precisely controlling pressure and temperature, and conducting long-term or short-term tests, it comprehensively evaluates the pipe's pressure resistance, creep resistance, and service life, providing a scientific basis for product quality assessment, production process optimization, and safe usage. 


Principle:

Test pieces are subjected to a specified constant internal hydrostatic pressure for a specified period of time or until a test piece or pieces fail.

Throughout the test, the test pieces are kept in an environment at a specified constant temperature: this is commonly in water (“water-in-water” test).

The following test parameters shall be specified by the standard or specification making reference to this part of ISO 1167:

a) the type of end cap to be used (see 5.1 and ISO 1167-2:2006, 4.1);

b) the test temperature;

c) the number of test pieces;

d) the duration of the test under pressure and the criteria for a failure;

e) the test pressure, p, or the circumferential (hoop) stress, σ, to be induced by the test pressure.

What Is Hydrostatic Pressure Testing?

Hydrostatic Pressure Testing or hydrotest of pipes is a specialized testing method used to assess the pressure resistance performance of pipes under constant pressure and temperature, mainly applied to quality inspection of plastic, composite, and other types of pipes.

Testing Principle: By applying constant pressure inside the pipe and maintaining it for a specified duration (such as 24 hours or longer), the test simulates the stress state under actual working conditions, observing whether any cracking, leakage, or deformation occurs, thus evaluating the material's pressure resistance strength and sealing ability.


In What Application scenario you need use the Hydrostatic Pressure Testing Equipment?

The static Hydrostatic Pressure Testing of pipes is mainly used to assess the pressure resistance and sealing performance of pipes under constant pressure, and its application scenarios cover multiple fields:
Gas Pipeline Safety Testing:Used for strength verification of underground polyethylene gas pipeline systems, simulating actual working conditions to test the pressure resistance of the pipeline, ensuring gas transportation safety. 
Plastic Pipe Performance Testing:Applicable to long-term pressure resistance testing of thermoplastic pipes such as PE, PVC, and PP-R, conducted according to the national standard ISO 1167 to evaluate their cracking resistance and sealing performance. 
Automotive Component Testing:Can determine the pressure endurance time and burst pressure values of automotive hoses, rubber hoses, air conditioning pipes, etc., ensuring the safety of automotive hydraulic systems. 
Metal Pipe Verification:Conduct macro strength and sealing tests on metal pipes such as steel and aluminum pipes to ensure the stability of metal pipelines under high-pressure environments. 
Other Material Testing:Applicable to pressure resistance evaluation of non-metallic materials such as rubber hoses and geothermal pipes, by controlling pressure and temperature parameters to simulate actual use scenarios.
