Companies in the Pressure Testing industry perform tests on various materials and products to determine their ability to withstand high levels of pressure. This industry is essential for ensuring the safety and reliability of products that are used in high-pressure environments, such as oil and gas pipelines, aerospace components, and medical equipment. Pressure testing involves subjecting a product to a range of pressures to determine its strength and durability. This can include hydrostatic testing, which involves filling a product with water and pressurizing it, or pneumatic testing, which involves using compressed air or gas to pressurize a product. Companies in this industry may also provide consulting services to help clients design products that can withstand high levels of pressure.
