Pressure Testers are responsible for ensuring that vessels and pipelines are safe and leak-free. They use a variety of testing methods to identify and repair leaks.

1. Conduct pressure tests

Pressure Testers conduct pressure tests on vessels and pipelines to ensure that they meet safety standards. They use a variety of testing methods, including hydrostatic testing, pneumatic testing, and vacuum testing.

• Hydrostatic testing involves filling a vessel or pipeline with water and then pressurizing the water to a predetermined level.
• Pneumatic testing involves filling a vessel or pipeline with air or nitrogen and then pressurizing the air or nitrogen to a predetermined level.
• Vacuum testing involves evacuating all air or nitrogen from a vessel or pipeline and then sealing the vessel or pipeline and monitoring the vacuum.

2. Identify and repair leaks

Pressure Testers identify and repair leaks in vessels and pipelines. They use a variety of methods to identify leaks, including visual inspection, ultrasonic testing, and radiographic testing.

• Visual inspection involves looking for leaks in vessels and pipelines.
• Ultrasonic testing involves using sound waves to detect leaks in vessels and pipelines.
• Radiographic testing involves using X-rays or gamma rays to detect leaks in vessels and pipelines.

3. Maintain records

Pressure Testers maintain records of all pressure tests and repairs. These records are used to ensure that vessels and pipelines are safe and compliant with safety standards.

• Records of pressure tests include the date, time, location, and results of the test.
• Records of repairs include the date, time, location, and description of the repair.
