Triton Alloys Inc manufactures Weld Neck Flange in all steel material grades, including carbon weld neck pipe flanges, stainless steel weld neck pipe flanges and alloy weld neck pipe flanges. Triton Alloys Inc also has many different weld neck pipe flanges in stock and ready to ship. Weld neck pipe flanges in stock include ASTM A182 weld neck flanges, ASME B16.47 Series "A" weld neck pipe flanges, ASME B16.47 Series "B" weld neck pipe flanges, Pressure Vessel weld neck pipe flanges. Triton Alloys Inc also manufactures custom weld neck pipe flanges per customer requirements. A weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange. There are two designs.
The regular type is used with pipes. These pipe flanges attach by welding the pipe to the neck of the flange. This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Lap Joint Flangeare often used for applications where high pressure is a factor. The inside diameter of the flange is designed to match the pipe's inside diameter. Weld Neck Pipe flanges with a hub have published specifications that range from 1/2" thru 96". Our company provides these in all material grades, specifications and sizes. Stainless Steel Weld neck flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for weld neck pipe flanges, the standard height is 1/16" for Carbon Steel weld neck flanges under 400#. For weld neck pipe flanges of 400# and up, the standard weld neck pipe flange raised face height is 1/4".
