Blind Flanges

A blind Flange is a flange which has no bore, and is used to close ends of piping systems. A blind flange also permits easy access to a line once it has been sealed. The blind flanges are sometimes machined to accept a pipe of the nominal Size to which reduction is being made. The reduction can be either threaded or welded.
Blind Flange manufacturer Landee supplies Blind Flanges, Industrial Blind Flanges, Blind Fittings in alloy steel, carbon steel, stainless steel, etc.

Lap Joint Flanges

Lap Joint Flanges (LJ Flanges) are used on piping fitted with lapped pipe or with lap joint stub ends the combined initial cost of the two items being approximately one-third higher than that of comparable welding neck flanges. Their pressure-holding ability is little, if any, better than that of slip-on flanges and the fatigue life of the assembly is only one-tenth that of welding neck flanges. The lap joint flange with the stub end assembly are normally used in systems requiring frequent dismantling for inspection and cleaning and where the ability to swivel flanges and to align bolt holes materially eases the erection of large diameter or unusually stiff piping. These flanges are also used in applications where there is a need to facilitate bolt alignment. Their use at points where severe bending stress occurs should be avoided.

Orifice Flanges

Orifice Flanges are used with orifice plate or flow nozzle for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Orifice flanges generally come with either raised faces or RTJ (Ring Type Joint) facings. Pairs of pressure tappings are machined into the orifice flange, making separate orifice carriers or tappings in the pipe wall unnecessary.

Orifice Flange manufacturer Landee supplies Orifice Flanges, Plate Flanges, Orifice Plates Fittings in alloy steel, forged steel, ductile iron, Stainless Steel etc.

Spacer Ring / Spade Flanges

In the oil and chemical process industries, a spade is a round piece of metal with a small tab that is placed in between two pipe flanges to give positive isolation from the centre; usually to prevent cross contamination between fluids or to allow work on the line.
Spacer Ring, Spade Flange, Special Flange manufacturer Landee supplies Spacer Rings Flanges, Spade Flanges, Special Flanges made in forged steel, Stainless Steel, alloy steel, etc.

Slip-on Flanges

Slip on weld Flanges are slipped over the pipe and welded (usually both inside and outside) to provide strength and prevent leakage. Slip-on Flanges are at the low cost end of the scale, and do not require high accuracy when cutting the pipe to length. These SO Flanges can sometimes have a boss or hub, and can be made with a bore to suit either pipe or tube.

Slip-On Flange manufacturer Landee supplies Slip On Flanges, SO Flanges, Slip-On Flanges in forged steel, Stainless Steel, alloy steel, etc.

Socket Weld Flanges

Socket Weld Flanges (SW Flanges) are similar to slip-on flanges in outline, but the bore is counter-bored to accept pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. The Socket Welding Flange is attached to the pipe by a fillet weld around the hub of the flange. An optional internal weld may be applied in high stress applications. The Socket Flanges' biggest use is in high pressure systems such as hydraulic and steam lines.

Socket Weld Flange / Fittings manufacturer Landee supplies Socket Welded Flanges, SW Flange, Socket welding Fittings, Socket Flanges in forged steel, Stainless Steel, alloy steel, etc.

Threaded Flanges

Threaded 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 manufacturer Landee supplies Threaded Flanges, Thread Fittings, Threaded Pipe Flanges in forged steel, Stainless Steel, alloy steel, etc.

Weld Neck Flanges

Weld Neck Flanges are flanges that designed to be joined to a piping system by butt welding. the WN Flange is relatively expensive because of its long neck, but is preferred for high stress applications. The neck, or hub, transmits stresses to the pipe, reducing stress concentrations at the base of the Welding-Neck flanges. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the Weld Neck flange. The bore of the Weld-Neck flange matches the bore of the pipe, reducing turbulence and erosion.
