A pipe flange is a disc, collar or ring that attaches to pipe with the purpose of providing increased support for strength, blocking off a pipeline or implementing the attachment of more items. They are usually welded or screwed to the pipe end and are connected with bolts. A gasket is inserted between the two mating flanges to provide a tighter seal. These flanges are either custom with dimensions provided by the customer or they are manufactured according to published specifications. Several organizations and associations have published specifications that provide dimensional information as well as pressure specifications at different temperatures. Our company manufactures custom designs and stocks six basic types of these products. Although, these are the six most common types, we are a custom manufacturer as well and are able to create just about any type of flange necessary for your requirements. Please click on one of the following pictures for a more detailed description of the item you are interested in. Each page also has a video that provides a better understanding of the installation process.
As made obvious by their name, these pipe flanges slip over the pipe. They're manufactured with an inside diameter that is slightly bigger than the pipe's outside diameter. These attachments are connected to the pipe via fillet weld at the top and bottom of the flange.
Slip on pipe flanges are typically provided with a raised or flat face. When a raised face is necessary for slip on pipe flanges, the standard height is 1/16" for slip on pipe flanges under 400#. For slip on pipe flanges of 400# and up, the standard slip on pipe flange raised face height is 1/4".
Coastal Flange manufactures slip on pipe flanges in all steel material grades, including carbon slip on pipe flanges, stainless steel slip on pipe flanges and alloy slip on pipe flanges. Coastal Flange also has many different slip on pipe flanges in stock and ready to ship. Slip on pipe flanges in stock include AWWA slip on pipe flanges, ANSI slip on pipe flanges, Pressure Vessel slip on pipe flanges and slip on pipe flanges that match the OD and drilling of ASME flanges.
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. Weld neck flanges are 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.
Weld neck pipe 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 weld neck pipe flanges under 400#. For weld neck pipe flanges of 400# and up, the standard weld neck pipe flange raised face height is 1/4".
Coastal Flange manufactures weld neck pipe flanges in all steel material grades, including carbon weld neck pipe flanges, stainless steel weld neck pipe flanges and alloy weld neck pipe flanges. Coastal Flange also has many different weld neck pipe flanges in stock and ready to ship. Weld neck pipe flanges in stock include ANSI B16.5 weld neck pipe 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. Coastal Flanges also manufactures custom weld neck pipe flanges per customer requirements.

Lap joint pipe flanges slide directly over the pipe and are most commonly used with stub end fittings. A pipe is usually welded to the Stub End and the Lap Joint pipe flange is free to rotate around the stub end. The benefit of this is that there will not be any issues with bolt hole alignment. Lap Joint pipe flanges are often used for applications that require frequent dismantling.
Slip on Pipe flanges with a hub have published specifications that range from 1/2" thru 24". Sizes above 24" are produced as lap joints to slip on dimensions. Coastal Flange provides Lap Joint pipe flanges in all material grades, specifications and sizes.
Coastal Flange manufactures lap joint pipe flanges in all steel material grades, including carbon lap joint pipe flanges, stainless steel lap joint pipe flanges and alloy lap joint pipe flanges. Coastal Flange also has many different lap joint pipe flanges in stock and ready to ship. Coastal Flange can also manufacture custom pipe flanges according to customer specifications.
