Flanges
Weld Neck Flange
We are certified to cater to the rigid and stringent requisites of the most critical of industries. Lap Joint Flanges are used with a stub end, which is welded to the pipe. Alloy Steel Lapped Joint Flanges are designed in a way that they swing over the pipe without the need to be welded. As they do not come in contact with the inner fluid, they do not corrode and can be re-used. Our ANSI B16.5 Stainless Steel Flanges are inexpensive and widely useful. In addition, they can be easily assembled and dismantled for quick inspection.

Frequenty Asked Questions
A flange is a protruding ridge or rim, often used to increase strength or spread the load. Pipe flanges form a rim that radially protrudes from the end of a pipe. They have several holes that allow two pipe flanges to be bolted together, forming a connection between two pipes. A gasket may be fitted between two flanges to improve the seal.
Pipe flanges are classified according to how they are attached to the pipe.
