Slip-on flanges are primarily used for seamless pipes and have pressure classes from 150 to 2500. Pressure is also measured at pressure values ranging from PN6 to PN64. 304L stainless steel flanges produce less carbide precipitation during welding, reducing intergranular and localized corrosion. The SS 304L blind flange is used for pipes where connections need to be closed. There are types such as weld neck flange and socket weld flange. All have different uses.

UNS S30403 pipe flanges are used in a variety of industries, from pharmaceuticals to petrochemicals, oil and gas, food processing, heat exchangers, and power plant applications. There are a variety of design models featuring lap joints commonly used with stub ends, such as the 304L SS lap joint flange. Flat, raised and ring surface connections are also possible. 304L stainless steel RTJ flanges feature ring connections. The flange consists of two ring halves, which are first welded to the end of the pipe and then to each other to create a better connection. Please contact us for a full product catalog and pricing.
