Forged Machined Flange

Forged Machined Flanges

We manufacture various type of steel flanges, pipe flanges, steel pipe flanges, stainless steel pipe flanges, stainless steel flanges as per customer recognized material standard (ASME/ANSI/DIN). The flanges are also manufactured as per customer specific requirement/ drawings.

Lap Joint Flanges

Lap Joint Flanges, while requiring a separate end connector, provides a joint in which the product does not come in contact with the flange. In addition the ability of the flange to rotate simplifies assembly and alignment of bolting on systems requiring frequent dismantling.

Slip-On Welding Flanges

Slip-On Welding Flanges are popular for normal service conditions because of the ease of fit up and alignment and the greater tolerance permissible in cutting the pipe to length.

Recommended fabrication practice is to weld at both the flange hub and the pipe end.

Socket Welding Flanges

Socket Welding Flanges are widely used for moderate services, particularly in the smaller sizes, because of the ease of fit-up and alignment. Although usually welded at the flange hub only, the pole end may also be welded without having to reface the flange. The end weld can be ground to provide a smooth bore.

Flanges Threaded Flanges

Threaded Flanges are widely used because no welding equipment is required for assembly and both the pipe and flange can be completely salvaged upon dismantling. Accurately cut, clean, tapered pipe thread dimensioned to ANSI A2.1 Pipe threads assure strong, tight joints.

Welding Neck Flanges

Welding Neck Flanges are designed to be butt welded to the pipe. The long tapered hub reinforces the flange, permits stress- relieving, magnafluxing or x-raying the weld, when required and removes the flange face from the heat affected zone.

These advantages make Welding Neck flanges particularly suitable for severe service involving high pressure, extreme temperatures or hazardous fluids. Production capability
