Pipe Hydrostatic Pressure Tester

The hydrostatic pressure resistance testing machine for pipes (also known as the hydrostatic testing machine for pipes) is an important testing device, mainly used to evaluate the performance and reliability of pipes under hydrostatic pressure conditions. The following are its main applications and applicable standards:

Main Applications

1. Determining Pipe Strength

The hydrostatic pressure resistance testing machine for pipes can simulate the pressure conditions in actual usage environments and conduct hydrostatic pressure tests on pipes, thereby determining the limit value of pressure that pipes can withstand. This helps to judge the strength and durability of pipes. 2. Detecting Pipe Reliability During the production and use of pipes, there may be manufacturing defects or installation problems, which may lead to leaks and other potential safety hazards in the pipeline system. Detection can be carried out through the hydrostatic pressure resistance testing machine for pipes. 3. Improving Pipe Sealing Performance In a pipeline system, the sealing performance of pipes is of great significance. The hydrostatic pressure resistance testing machine for pipes can detect leaks and problems at pipe connections, enabling timely repairs, improving the sealing performance of pipes, and ensuring the normal operation of the pipeline system.

Applicable Standards

The design and use of hydrostatic pressure resistance testing machines for pipes usually follow a series of national and international standards to ensure the accuracy and comparability of test results. The following are some common applicable standards: 1. GB/T 6111 - 2018 This is a regulation in China's national standards regarding the test method for internal pressure resistance of thermoplastic pipes for fluid transportation. This standard specifies in detail the testing equipment, specimen preparation, test methods, test conditions, and test results. 2. ISO 1167 This is a standard of the International Organization for Standardization on the test method for the hydrostatic pressure resistance performance of thermoplastic pipes. This standard is similar to GB/T 6111, but may include some internationally - commonly - used test methods and requirements. 3. Other Related Standards In addition to the above two main standards, the hydrostatic pressure resistance testing machine for pipes may also comply with other standards related to pipe performance, quality, and safety, such as GB/T 18477.2, GB/T 13663.2, and GB/T 13663.3.

Product Advantages:

1、Accurate Pressure Control: Provides precise control over the internal hydrostatic pressure applied to the pipe samples, as required by testing standards.

2、Simulates Service Conditions: Replicates the internal pressure pipes experience in real-world fluid transportation applications.

3、Objective Performance Data: Yields quantitative data on pressure resistance and time to failure, allowing for objective evaluation of pipe quality and reliability.

4、Detects Flaws and Weaknesses: Effective in identifying manufacturing defects, material inconsistencies, or issues with joints and seals.

Product Features:

1、A high-pressure pump or pressure generation system capable of producing the required hydrostatic pressure within the pipes.

2、A precise pressure control system to maintain the set pressure accurately for the duration of the test or increase pressure at a controlled rate.

3、Test stations equipped with end closures or fittings designed to securely seal the ends of pipe samples of various diameters.

4、Often includes a temperature-controlled water bath or chamber where the pipe samples are immersed during the test to maintain a constant test temperature, which is critical for the hydrostatic properties of many pipe materials (especially plastics).
