Large-diameter Carbon Steel Neck Butt-welding Flange, 304 Stainless Steel National Standard

Compared with ordinary flanges, large butt-welding flanges have significant structural advantages. It has a long neck, which plays a key role in pipeline connection, and can effectively disperse the pressure on the connection part, making the connection between the flange and pipeline more stable and reliable. The process of manufacturing large butt-welding flanges is complex and rigorous. First of all, the choice of raw materials, more use of high-quality carbon steel 20 #, 16MN 1CR13 2CR13, alloy steel 1CR13 2CR13 or stainless steel 316 304 and other materials, according to the specific application scenarios to determine. It is widely used in high-pressure pipeline systems, such as long-distance transportation pipelines for oil and gas, and high-pressure pipelines for large-scale chemical plants. In terms of high-temperature resistance, it can adapt to high-temperature environments of several hundred degrees Celsius, like steam transmission pipelines in thermal power plants, and protect the safety of pipelines in the fields of chemical industry and ocean engineering.
