3 stations standard INTERNAL PRESSURE TEST MACHINE.

Standard

ASTM D1599 Pipe short-time hydraulic burst pressure test –

ASTM D1599 is titled "Standard Test Method for Resistance to Short-Time Hydraulic Pressure of Plastic Pipe, Tubing, and Fittings." It is a fundamental short-term, destructive pressure test used to determine the ultimate failure pressure (often called the "burst pressure") of thermoplastic pipe, tubing, or fittings under rapidly applied internal pressure at a specified temperature. Typically completed within 60–70 seconds, mainly for quality control and short-term design validation.

ASTM D1598 test for long-term hydrostatic pressure of plastic pipe –

ASTM D1598 is a standard test method that determines the time-to-failure of thermoplastic and reinforced thermosetting/resin pipes under constant internal pressure at a controlled temperature, which is critical for establishing hydrostatic design basis and ensuring long-term pipeline reliability.

ASTM D1598, D1599 Plastic Pipe Constant or short time pressure testing methods –

ASTM D1598: Standard Test Method for Time-to-Failure of Plastic Pipe Under Constant Internal Pressure.

ASTM D1598 test method covers the determination of the time-to-failure of both thermoplastic and reinforced thermosetting/resin pipe under constant internal pressure.This test method provides a method of characterizing plastics in the form of pipe under the conditions prescribed.

ASTM D1599: Standard Test Method for Resistance to Short-Time Hydraulic Pressure of Plastic Pipe, Tubing, and Fittings.

ASTM D1599 test method establishes the short-time hydraulic failure pressure of thermoplastic or reinforced thermosetting resin pipe, tubing, or fittings. Data obtained by this test method are of use only in predicting the behavior of pipe, tubing, and fittings under conditions of temperature, time, method of loading, and hoop stress similar to those used in the actual test. They are generally not indicative of the long-term strength of thermoplastic or reinforced thermosetting resin pipe, tubing, and fittings

ISO 1167 Thermoplastics pipes resistance to internal pressure test –

ISO 1167: 2006 Thermoplastics pipes, fittings and assemblies for the conveyance of fluids -- Determination of the resistance to internal pressure.

ISO 1167 test method specifies a general test method for determining the resistance to internal hydrostatic pressure at a given temperature of thermoplastics pipes, fittings and piping systems for the transport of fluids. The method accommodates water-in-water, water-in-air and water-in-liquid tests.

Hydrostatic pressure testing is a valuable method for assessing the strength and integrity of pressurized systems, ensuring that they can meet operational demands without failure. Hydrostatic pressure testing can evaluate these items by filling pipelines, tanks, or containers with water before pressure is applied to detect any potential leaks or issues.

Hydrostatic pressure tester is critical across multiple industries, from pipeline engineering to industrial piping. It helps prevent costly failures or leaks by verifying whether the system can safely reach the specified pressure levels.

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.
