01

Overview

We supply a complete range of forged flanges and pipe fittings across every alloy grade we stock. Flanges are offered from 1/2" to 48" NB in all standard pressure classes, while our butt-weld and socket-weld fittings cover elbows, tees, reducers, caps and couplings for every piping configuration.

Every piece is manufactured to ASME B16.5 / B16.47 (flanges) and ASME B16.9 / B16.11 (fittings), with complete material traceability and Mill Test Certificates on every batch.

  • Flanges: ASME B16.5 & B16.47
  • Fittings: ASME B16.9 & B16.11
  • Size Range: 1/2" to 48" NB
  • Traceability: Full Mill Test Certificates (MTC)

Flange Types

A complete range of forged flanges to suit every piping connection, pressure rating and maintenance requirement.

Weld Neck Flange

Weld Neck Flange

Tapered hub welded to the pipe for high-pressure, high-stress applications with excellent stress distribution.

Slip-On Flange

Slip-On Flange

Slides over the pipe and is fillet welded top and bottom — economical and easy to align during installation.

Blind Flange

Blind Flange

Solid disc used to seal the end of a piping system or vessel opening, allowing future access.

Socket Weld Flange

Socket Weld Flange

Pipe inserted into a recessed socket and fillet welded — ideal for small-bore, high-pressure lines.

Threaded Flange

Threaded Flange

Screwed onto pipe with matching NPT threads — used where welding is impractical or hazardous.

Lap Joint Flange

Lap Joint Flange

Used with a stub end, allowing free rotation for easy bolt-hole alignment and frequent dismantling.

03

Pipe Fitting Types

Butt-weld and socket-weld / threaded fittings to change direction, branch, reduce or terminate a pipe run.

Elbow Fitting

Elbow (45° / 90°)

Changes the direction of flow — available in short radius and long radius, butt-weld or socket-weld.

Tee Fitting

Equal / Reducing Tee

Creates a branch connection at 90° to the main run, in equal or reducing outlet configurations.

Reducer Fitting

Concentric / Eccentric Reducer

Joins two pipes of different diameters, keeping the flow either centred or offset along one edge.

Cap Fitting

End Cap

Seals the open end of a pipe run — welded directly onto the pipe end.

Coupling Fitting

Coupling

Joins two pipes of the same diameter in a straight line — full and half-coupling options available.

Union Fitting

Union

Threaded three-piece fitting allowing quick disconnection of a line for maintenance without cutting pipe.

04

Surface Finishes

Pick the finish that matches your installation environment — from as-forged stock to a fully machined face.

Machined Finish

Smooth, precision-machined raised face or flat face — ready for direct gasket seating.

Black / As-Forged

As-forged surface with mill scale intact — the standard for further machining or coating.

Serrated / Smooth Face

Concentric or spiral serrated face for improved gasket grip, or smooth face for soft gaskets.

05

Grades Available

Flanges & fittings are stocked across all five alloy families, each manufactured to its respective ASTM standard.

Titanium
