Quality assurance

Certified,
then proven
again.

A certificate says what the metal should be. Our own lab checks that it is — chemistry, strength, alloy and pressure, on site — before anything leaves with a material test certificate raised against its heat.

In our own lab

Six things we
measure ourselves.

Testing on site means a result in hours rather than a queue at an outside lab — and the people who made the part are the people who have to answer for it.

Results reviewed at the lab workstation

Spectrometer, on site

Chemical analysis

Composition confirmed against the grade before the heat is released.

Method
Spectrometer, on site
It proves
The alloy is the grade on the order
When
Before the heat is released
A hand-held test instrument on the inspection bench

Tensile, hardness

Mechanical testing

Strength and hardness verified on samples taken from the same heat.

Method
Tensile, hardness
It proves
Strength and hardness meet the grade
When
On samples from the same heat
An operator at the process tank line

Intergranular, pitting

Corrosion testing

Resistance checked for the service the material is specified for.

Method
Intergranular, pitting
It proves
Resistance for the specified service
When
Against the service on the order
Bar stock checked against its paperwork in the raw material area

PMI, hand-held

Positive material identification

The part in your hand read directly, not inferred from a label.

Method
PMI, hand-held
It proves
The alloy of this exact part
When
On receipt, before the strapping comes off

Pressure holding

Hydrostatic & pneumatic

Joints held at pressure and watched for decay or leak.

Method
Pressure holding
It proves
The joint holds pressure
When
On the sampling plan
Dimensional inspection on the vision measuring machine

Gauges and CMM

Dimensional inspection

Threads, bores and faces measured against the drawing.

Method
Gauges and CMM
It proves
Every dimension to drawing
When
First-off, then every piece

With every consignment

The paperwork
travels with it.

A fitting nobody can trace is a fitting your inspector has to reject. Everything here leaves with the goods, so the consignment can be accepted on its documents alone.
