Importance of non-destructive testing in pipe fitting production
Non-destructive testing is used to identify defects that may occur in materials or processing. The non-destructive testing requirements specified in different standards are inconsistent, and common methods include:
• Ultrasonic testing
• Radiographic testing
• Magnetic particle testing
• Penetrant testing
Manufacturers will also add testing steps based on internal quality control standards or customer requirements to ensure that the product meets the standards. Testing qualifications should be determined based on orders or relevant standards.

Why are elbows made of stainless steel?
Stainless steel stamped elbows are suitable for pipeline systems in petroleum, chemical, hydropower, natural gas, construction, and steam storage tank industries because they can be used directly as raw materials without the need for blanks. Large-diameter thin-walled carbon steel elbows can serve as low-cost pipe-making equipment and molds. By shortening the production cycle, production management costs can be significantly reduced. Especially for large steel elbows, the blank surface is smooth, with good ductility, and the stamping process is simple, precise, easy to operate, and assembly and welding processes are also very convenient.
