Weld Neck Flanges

Long tapered hub is butt-welded to the pipe for a smooth, reinforced joint.

Best suited to high-pressure, high-temperature and cyclic-load applications.

Slip-On Flanges

Slides over the pipe end and is fillet-welded both inside and outside.

Quick and economical to align and install on low to medium pressure lines.

Threaded Flanges

Screws directly onto externally threaded pipe, with no welding needed.

Suited to low-pressure lines and hazardous areas where welding is unsafe.

Blind Flanges

A solid disc used to blank off the end of a pipeline or valve completely.

Ideal for pressure testing, line isolation and future extensions.

Socket Weld Flanges

The pipe is inserted into a machined socket and fillet-welded in place.

Gives a smooth bore, ideal for small-diameter, high-pressure piping.

Lap Joint Flanges

Rotates freely over a stub end, so bolt holes line up easily on site.

Perfect for systems that need frequent dismantling or inspection.

Reducing Flanges

Connects pipes of two different sizes within a single flange.

Removes the need for a separate reducer fitting in the line.

Forged Steel Flanges

Forged from a solid billet of steel for maximum strength and reliability.

Withstands high pressure, heavy loads and demanding service conditions.

Long Weld Neck Flanges

An extended hub reaches deep into a vessel, tank or nozzle wall.

Used where the flange must project through insulation or a nozzle.

Ring Type Joint Flanges

A grooved face compresses a metal ring gasket for a metal-to-metal seal.

Built for the most extreme pressure and temperature applications.

Orifice Flange Assembly

A paired flange set with tap holes for mounting an orifice plate.

Used to measure flow rate accurately at a point in the pipeline.

Pipe Flanges

A general term for flanges welded or fitted to the end of a pipe section.

Used wherever a pipeline needs a bolted connection point.

Welded Flanges

Any flange that is joined to the pipe by welding rather than threads.

Includes weld neck, slip-on and socket weld styles.

Plate Flange

A flat plate-style flange, often used as a low-cost slip-on connection.

Suited to lighter-duty, low-pressure piping runs.

Screwed Flanges

Another name for threaded flanges, screwed onto externally threaded pipe.

Used where welding on site isn't practical or safe.

DIN Flanges

Manufactured to the German DIN standard dimensions and PN pressure ratings.

Common on piping projects specified to European standards.

ANSI Flanges

Manufactured to ANSI/ASME B16.5 dimensions and class ratings.

The most widely used flange standard in oil & gas and process plants.

Metal Flanges

A general term covering flanges made from any metal, not just steel.

Includes stainless, carbon steel, alloy and nickel-alloy variants.

Welding Flanges

Covers any flange style that is attached to the pipe by welding.

Chosen based on pressure, temperature and maintenance needs.

ASME Flange

Manufactured to ASME B16.5 / B16.47 dimensional standards.

Ensures interchangeability across bolts, gaskets and mating flanges.

Steel Lap Joint Flanges

A lap joint flange in carbon or stainless steel, rotating over a stub end.

Simplifies alignment in systems that need frequent dismantling.

ASTM Flanges

Manufactured from steel meeting ASTM material specifications.

Defines the chemical and mechanical properties of the flange material.

PN Flanges

Rated to the European PN (Pression Nominale) pressure classes.

Used on pipelines built to DIN/EN dimensional standards.

Puddle Flanges

A flange with a solid plate section, cast or welded onto a pipe for embedding in concrete.

Prevents water seepage where a pipe passes through a wall or slab.

Round Flange

A standard circular flange, the most common flange shape.

Fits round pipes and matches round-pattern bolt circles.

Split Flange

Made in two half-sections that bolt around the pipe.

Allows installation or removal without disturbing the rest of the pipeline.

Cast Flanges

Produced by casting molten metal into a mould rather than forging.

An economical option for lower-pressure, non-critical applications.

PTFE Lined Reducing Flange

A reducing flange with a PTFE lining for chemical resistance.

Used to step down pipe sizes in highly corrosive process lines.

SO Flange

Short form for Slip-On flange, sliding over the pipe end before welding.

Quick to align and economical for low to medium pressure lines.

Flange Connector

A general term for any flange used as a connection point between pipe ends or equipment.

Selected based on the specific pressure, size and service conditions.
