    PIPE FLANGES
    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. Slip-On Pipe Flanges SLIP-ON Slip-on pipe flanges actually slide over the pipe. They are typically machined with an inside diameter slightly larger than the outside diameter of the pipe. This allows the flange to slide over the pipe but to still have a somewhat snug fit. Slip-ons are secured to the pipe with a fillet weld at the top and the bottom of the flange. These are further catagorized as a ring or a hub. Rings and hubs are both considered slip on flanges because they both fit over the pipe. Weld Neck Pipe Flanges WELD NECK Weld neck pipe flanges are installed by welding the pipe to the neck of the flange. This allows for the transfer of stress from the flange to the pipe itself. This also reduces high stress concentration at the base of the hub. Weld necks are
