Stainless steel threaded elbow is a pipe fitting that connects and changes the direction of the pipeline through threaded connection. As an important component of stainless steel threaded fittings, it has excellent corrosion resistance, mechanical strength, and sealing performance. Therefore, it is widely used in various fields such as industry, chemical industry, oil and gas, food, etc. In the selection and use process, it is necessary to fully consider factors such as pipeline diameter, elbow angle, material quality, usage environment, and working pressure to ensure the safe, reliable, and efficient operation of the pipeline system.
Stainless steel threaded elbow shape is usually 45 degrees, 90 degrees. The production of stainless steel threaded elbows also needs to follow international production standards, such as GB/T14383, ASME B16.11, etc., to ensure that the quality and performance of the products meet the requirements.
ASME B16.11 Stainless Steel Threaded Elbow
ASME B16.11 is a production standard for forged fittings, which includes fittings with socket and threaded connections. It specifies requirements for material, size, shape, pressure rating, tolerance range, etc. to ensure their safety and reliability in the industrial field. This standard covers various types of forged fittings, such as forged elbows, tees, couplings, caps, plugs,etc.
