Stainless steel slip on flange (SO flange) manufactured in accordance with ANSI B16.5 standard. Available in SS304, SS316. Widely used in petroleum, chemical, water treatment and pipeline engineering. Stable structure, easy installation.
Weld neck pipe flanges attach to the pipe by welding the pipe to the neck of the pipe flange. The allows for the transfer of stress from the weld neck pipe flanges to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck pipe flanges are often used for high pressure applications. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe.
