Ultrasonic testing of ASME SA514 GR.A Normalized Pressure Vessel Steel plate material:
Testing requirements
When carbon steel and low-alloy steel plates (excluding laminates of multi-layer pressure vessels) with a thickness of ≥12mm are used to manufacture the main pressure components of pressure vessels, ultrasonic testing shall be carried out one by one if they meet one of the following conditions:

1) Steel plates for pressure vessels containing extremely or highly hazardous media;
2) Steel plates for pressure vessels used in wet H2S corrosive environments;
3) Steel plates for pressure vessels with design pressure ≥ 10MPa (high pressure vessels);
4) Steel plates for pressure vessels that are required by product standards or designers to conduct ultrasonic testing one by one.
There are many types of steel used in pressure vessels, including steel plates, steel pipes, castings and forgings, and various shaped steels. In order to control and guarantee the quality of these raw materials, the country has formulated a series of standards. Steel plates are the main materials for manufacturing pressure vessels. According to their rolling methods, there are cold-rolled thin plates and hot-rolled thick plates; according to the types of materials, there are carbon steel plates. , low-alloy steel plate, high-alloy steel plate 1 composite steel plate of stainless steel and carbon steel or low-alloy steel, and non-ferrous metal plates such as copper, aluminum, titanium; according to the use of materials, there are general plates, container plates, boiler plates, marine plates, etc. .
