What is The Most Common Types of Pipe Flanges?

Pipe flanges can be split into eight types based on design. These types are blind, lap joint, orifice, reducing, slip-on, socket-weld, threaded, and weld neck.

Blind Flange

Blind flanges are round plates with no center hold used to close the ends of pipes, valves, or equipment. They help in allowing easy access to a line once it has been sealed. They can also be used for flow pressure testing. Blind flanges are made to fit standard pipes in all sizes at higher pressure ratings than other flange types.

Weld Neck Flange

Weld Neck Flanges Manufacturers Exporters Suppliers Welding neck flanges have a long-tapered hub and are used for high pressure applications. The tapered hub conduct stress from the flange to the pipe itself and provides strength increase that counteracts dishing.

Slip-on Flange

Slip On Flange Exporters In India Slip-on flanges are designed to slide over the end of piping and then be welded in place. They supply easy and low-cost installation and are ideal for lower pressure applications.

Lap Joint Flange

Lap Joint Flange Exporters In India Lap joint flanges are used on piping fitted with lapped pipe or with lap joint stub ends. They can turn around the pipe to allow for an easy alignment and assembly of bolt holes even after the welds have been completed. Because of this advantage, lap joint flanges are used in systems need frequent disassembly of the flanges and pipe. They are similar to slip-on flanges, but have a curved radius at the bore and face to accommodate a lap joint stub end. The pressure ratings for lap joint flanges are low, but are higher than for slip-on flanges.

Threaded Flange

Threaded Flanges Manufacturers Exporters Suppliers Threaded flanges are special types of pipe flange that can be attached to the pipe without welding. They are threaded in the bore to match outer threading on a pipe and are tapered to create a seal between the flange and the pipe. Seal welds can also be used along with threaded bond for added reinforcement and sealing. They are best used for small pipes and low pressures, and should be avoided in applications with large loads and high torques.

Socket Weld Flange

Socket Weld Flanges Manufacturers Exporters Suppliers Socket weld flanges are perfect for small-sized, high-pressure piping. Their fabrication is related to that of slip-on flanges, but the inner pocket design allows for a smooth bore and better fluid flow. When internally welded, these flanges also have exhaustion strength 50% greater than double welded slip-on flanges.

If we don’t have your flanges in stock, we will make it to order. we are glad to consult on the categories of flanges and different pipe fittings required for your project. Please contact us therefore we are able to start building your custom fittings ASAP.

Each ISO Flanges is otherwise designed based on the characteristics of the applying and additionally the pressure. Consequently, different industries use different flange. We also produce customized industrial flanges at our factory as per our client’s requirements. For any types of Industrial Flanges Price List Call on +91 9152160158 or drop an Email to |
