Ball valve weld strength
Thread Content
How to calculate the weld strength of welded ball valves, including the weld strength of the valve body, the shaft sleeve welds, and the flange welds that connect to the turbine
The valve factory can perform strength calculations; the customer only needs to confirm the design. Similar to the Australian regulations, API600 valves require a corrosion allowance of 3 mm; I, as the pipeline representative, reviewed the detailed design drawings prepared by the company’s technical department, in accordance with standards such as ASME B16.34.
