On-Site & Shop Pressure Testing Services

Pressure Testing examines the integrity and strength of tubing, piping, pressure vessels, tanks and other components (e.g. heat exchangers, filters, valves) using a pressurized fluid (e.g. water, air or inert gas). The primary purpose of the test is to demonstrate the ability to meet project specification(s) without leaks, deformation, catastrophic failure, or rupture. It is especially essential for systems that operate under pressure, as these systems typically require validation prior to operations.

Astro Pak can provide both on-site and in-house shop based hydrostatic and pneumatic testing of piping, equipment and components for a wide range of industries including aerospace, industrial, biotechnology, chemical, food, beverage and other industrial plants.

Astro Pak went above and beyond and stayed well after normal working hours to ensure the job was completed. They kept me informed throughout the process and found solutions to issues as they arose.
