GNEE is a professional exporter of ASTM A249 stainless steel pipes, with an annual export volume of 10,000 tons.
ASTM A249 TP321 stainless steel pipes are generally considered to have comparable weldability to 304 and 304L stainless steels, with the main difference being the addition of titanium, which reduces or prevents carbide precipitation during welding.
ASTM A249 TP321 ERW steel pipes are available in a variety of specifications, including different outer diameters and wall thicknesses. Custom sizes and shapes of stainless steel pipes can be provided according to customer project requirements.
During the production process of ASTM A249 stainless steel 321 welded pipes, quality control measures such as eddy current flaw detection devices, hydraulic units, physical and chemical laboratories, and ultrasonic flaw detection are used to ensure that the quality and performance of the products meet the standard requirements.
