Tirupati Enterprises is a trusted manufacturer, exporter, and supplier of Lapped Joint Flanges and Stainless Steel Flanges (Grades 304, 304L, 316, 316L), available in various materials, finishes, and sizes in both metric and inch standards. Our Lapped Joint Flanges are manufactured in different materials, including:
These flanges conform to Slip-On specifications and are widely supplied across India and Asia.
Lap Joint Flanges are similar to other industrial flanges but do not have a raised face. They are designed to be used with a Lap Joint Stub End, which allows for easy alignment and rotation. While the initial cost of a Lap Joint Flange along with a stub end is higher compared to a welding neck flange, they are highly preferred in piping systems requiring frequent dismantling for inspection and cleaning.
The pressure holding capacity of Lap Joint Flanges is lower compared to other flange types, and the fatigue life of the assembly is approximately one-tenth of a welding neck flange. These flanges slip over the pipe and are not welded or permanently attached, allowing for easy adjustment. The bolting pressure is transferred to the gasket through the flange pressing against the stub end.
