| Stainless Steel Seamless Weld Fitting 90 Degree Elbow
Adhere to strict manufacturing standards, such as GB/T 12459, ASME B16.9, etc. The surface is polished and smooth without burrs, further improving the corrosion resistance and aesthetics. Stainless steel 90-degree elbows are available in a variety of sizes and pressure grades to meet different engineering needs.
Proper maintenance and adherence to strict manufacturing standards are crucial for the optimal performance of stainless steel 90-degree elbows. Regular inspection and cleanliness play a significant role in ensuring the longevity and efficiency of these components. By promptly addressing any abnormalities or signs of wear, potential issues can be prevented, ultimately enhancing the safety and functionality of the project. It is imperative for operating personnel to prioritize the inspection of transmission threads and internal parts to guarantee a seamless flow of fluids or gases within the system.

The welding process requirements for stainless steel elbows are very strict, and these requirements make sure the reliability and durability of stainless steel 90-degree elbows under various media and temperature conditions.
(1) Material selection: stainless steel butt weld elbow manufacturing material can be austenitic stainless steel, such as 304, 304L, 316, 316L, etc., the specific material according to the working conditions and the corrosion of the medium.
(2) Beveled end: The end of the connection between the 90 elbow and the seamless pipe needs to be beveled, so as to weld easier.
(3) Cleaning requirements: Before welding, it's necessary to thoroughly clean the surface of stainless steel elbow pipe fittings to remove the oil, rust and sust to ensure the quality of the weld.
(4) Welding process: High quality welding methods such as TIG (tungsten argon arc welding), or MIF (metal inert gas shielded welding).
(5) Welding parameters: Parameters such as current, voltage, speed and protective gas flow need to be precisely controlled to ensure the uniformity and quality of the weld.
(6) Preheat and post heat treatment: Depending on the thickness of stainless steel pipe elbow and welding requirements to do heat treatment. It can reduce heat affected zone stress and prevent intergranular corrosion.
(7) Welder qualification
(8) Non-destructive test: It's vital to conduct non-destructive testing after finishing welding process such as X-ray testing (RT) or ultrasonic testing (UT), to check whether there are defects inside the weld.
(9) Cleaning and passivation: Restore the corrosion resistance of stainless steel.
(10) Pressure test: Before installation, stainless steel seamless 90-degree elbows need to be pressure tested to ensure that their pressure resistance meets the design requirements.
