Forged flange, It is invented on the basis of the cast flange into production, its intensity to be higher than the cast steel flange many interconnected so that the tube with the tube parts, is connected to the tube end.

the forged flange has the higher production cost, but the lower carbon content, higher rust resistance, better seamline, intensive inner texture, and stronger mechanical property than the cast flange. The forging craft will not make the coarse or uneven-sized grains, so the crack caused by solidification will not happen on the forged flange.

We are a largest Manufacturer, Supplier and Exporter of Thread Flanges, ASME 16.5 Threaded Flanges. Threaded Flanges (Screwed flanges)are similar to slip-on flanges in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. Threaded Flanges may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing the flanges’ pressure applications. Threaded flange use in low press condition usually. These flanges are normally designed for low pressure, non-cyclic applications. They are also used in applications where welding is hazardous. Threaded flanges are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications. Threaded Flanges are available in following specifications:

We are Manufacturer, Supplier and Exporter of Slip-on pipe flange, ASME 16.5 Slip On Flanges / SORF Flanges. Slip-on pipe flange usually slips over the pipe. Slip-on pipe flanges are typically made with an inside diameter of the pipe flange slightly larger than the outside diameter of the pipe. This allows the slip-on flange to slip over the pipe. Slip-on pipe flanges are welded (usually both inside and outside) to provide strength and prevent leakage. Slip-on pipe flanges can sometimes also have a boss/ring or hub, and can be made with a bore to suit either pipe or tube. Ring pipe flanges and hub pipe flanges are both considered slip-on pipe flanges because they both slip over the pipe. Slip-on flanges are easy to use in fabricated applications. These flanges are attached to the pipe by fillet welding at the hub and at the end of the pipe inside the flange. These are available in wide variety of sizes and applications.

Slip-on flanges are generally preferred by users over weld neck flanges, as they are a cheaper option than weld neck flange and the fact that less accuracy is required when cutting pipe to length.

Slip-on flanges are available with raised, flat or RTJ faces, and are also available in orifice configurations.

We are largest Manufacturer, Supplier and Exporter of ASME 16.5 Flat Flanges. The Flat Face flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.

Flat face flanges are never to be bolted to a raised face flange. ASME B31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required. This is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange, Our flat flanges sit flat on the ground and have a neck. The flat face (full face) flange has a gasket surface in the same plane as the bolting circle face.

We are largest Manufacturer, Supplier and Exporter of high Quality Ring Type Joint Flanges / RTJ Flanges. Ring joint flange is a special type of flange connection in which a metal ring (resting in a groove in the flange) serves as a pressure seal between the two flanges. This jointing method can be employed on Weld Neck, Slip-on and Blind Flange.

RTJ flanges have grooves cut into their faces which accept steel Ring Gaskets. RTJ flanges seal when tightened bolts compress the gasket between the flanges into the grooves, deforming (or “Coining”) the gasket to make Intimate Contact inside the grooves, creating a metal to metal seal.

Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flange. Ring Type Joint Flanges / RTJ Flanges are available in following specifications:

We are Manufacturer, Supplier and Exporter of Slip-on pipe flange, ASME 16.5 Slip On Flanges / SORF Flanges. Slip-on pipe flange usually slips over the pipe. Slip-on pipe flanges are typically made with an inside diameter of the pipe flange slightly larger than the outside diameter of the pipe. This allows the slip-on flange to slip over the pipe. Slip-on pipe flanges are welded (usually both inside and outside) to provide strength and prevent leakage. Slip-on pipe flanges can sometimes also have a boss/ring or hub, and can be made with a bore to suit either pipe or tube. Ring pipe flanges and hub pipe flanges are both considered slip-on pipe flanges because they both slip over the pipe. Slip-on flanges are easy to use in fabricated applications. These flanges are attached to the pipe by fillet welding at the hub and at the end of the pipe inside the flange. These are available in wide variety of sizes and applications.

Slip-on flanges are generally preferred by users over weld neck flanges, as they are a cheaper option than weld neck flange and the fact that less accuracy is required when cutting pipe to length.

Slip-on flanges are available with raised, flat or RTJ faces, and are also available in orifice configurations.

Ring joint flange is a special type of flange connection in which a metal ring (resting in a groove in the flange) serves as a pressure seal between the two flanges. This jointing method can be employed on Weld Neck, Slip-on and Blind Flange.

RTJ flanges have grooves cut into their faces which accept steel Ring Gaskets. RTJ flanges seal when tightened bolts compress the gasket between the flanges into the grooves, deforming (or “Coining”) the gasket to make Intimate Contact inside the grooves, creating a metal to metal seal.

Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flange. Ring Type Joint Flanges / RTJ Flanges are available in following specifications:
