How it works — bar to bundle

01 / 07

Reception.

BAR, HOLLOW AND FORGING STOCK BOOKED AGAINST AN APPROVED HEAT. MILL CERTIFICATES ARE READ BEFORE THE STRAPPING COMES OFF. HOLD · PMI ON RECEIPT

02 / 07

CNC.

THE FLOOR RUNS MULTI-AXIS TURNING AND MILLING CELLS UNDER ONE ROOF, SO A PART NEVER LEAVES THE BUILDING BETWEEN OPERATIONS.

03 / 07

Forged.

STOCK IS HEATED AND UPSET TO A NEAR-NET SHAPE, THEN NORMALISED. GRAIN FLOW FOLLOWS THE BODY RATHER THAN BEING CUT ACROSS IT.

04 / 07

Machined.

BAR IS TURNED, DRILLED AND THREADED ON CNC CELLS. FIRST-OFF IS GAUGED BEFORE THE RUN, AND EVERY PIECE AFTER IT AGAINST THE SAME SETTING. HOLD · FIRST-OFF

05 / 07

Inspected.

DIMENSIONAL CHECK AGAINST THE GAUGE, HARDNESS, POSITIVE MATERIAL IDENTIFICATION AND A PRESSURE TEST ON THE SAMPLING PLAN. HOLD · TPI WELCOME

06 / 07

Packed.

COUNTED, BAGGED AND BOXED; TUBE BUNDLED INTO ISPM-15 HEAT-TREATED CRATES. THE HEAT NUMBER AND ITS TEST CERTIFICATE TRAVEL WITH THE GOODS. HOLD · CERTIFICATE

Qualifications

Paper that
travels with it.

Certification is not a badge on a homepage. Every consignment leaves with the documents that let your inspector accept it without a phone call.

Mechanically attached fittings ASTM F1387-23 OTFI brand fittings tested to the 2023 standard for mechanically attached fittings — the performance the rest of the range is built to.

ISO 9001:2015 Quality management, audited annually.

Interchangeability with Swagelok® Double-ferrule fittings inspected against Swagelok® and found to interchange when assembled to the recommended instructions.

With every consignment EN 10204 3.1 material test certificate Raised against the heat the parts were made from. Full certificates on file and sent with the quotation on request.

Materials

Whatever grade
the spec calls for.

Standard fittings and tubing ship in 316/316L. The same tooling runs the rest of the range, with the same heat-traceable certificate trail behind every one. Hover a grade and the band takes its colour.

01 / 05 · The elbow

Skip story ↗

The OM6 fitting, part by part

Four parts. One seal.
Two of them are ferrules.

A ¼-inch OM6 union elbow in 316L, straight off the line. Follow this fitting from the outside in, then onto the test bench.

What is inside the nut

One connection.
Every part has a role.

Scroll to open one end of the elbow and reveal the two ferrules. Select a part to explore its role.

AssembledFour components. One connection.

04 / 04

The foundation.

The elbow body turns the flow through 90 degrees and provides the seat for the front ferrule.

Before the bench, the standard

A small fitting.
A demanding programme.

ASTM F1387-23 puts the connection through repeated assembly, pressure, bending and more. Explore what each test asks of the fitting.

Same elbow.

The connection is assembled onto the tube. Now the pressure rises. Watch the actual bench footage and follow what happens to the joint.

The connection, after the test

The tube let go.
The fitting didn't.

The wall failed away from the joint. The ferrules held the tube, and the connection stayed sealed.

Field deployments

Engineered for
severe-duty service.

Five sectors take the bulk of what leaves the plant. Each one sets its own corrosion, temperature and pressure case — and its own certificate trail.

Christmas trees, wellhead manifolds, top-side skids and subsea tie-backs — NACE MR0175 compliant.

02 / 05

Refining & midstream

Hydrocracking units, delayed coking, catalytic reformers and high-temperature flare lines.

03 / 05

Petrochemical & fertiliser

Ammonia, urea synthesis and aggressive acid process piping.

04 / 05

Power & steam generation

Boiler superheater tubes, high-pressure steam distribution and condenser lines.

05 / 05

Marine & subsea

Ballast water treatment, FPSO topside piping and high-salinity seawater intake.
