Quality assurance

Our quality department does not report to production

That single structural decision is the whole of our quality story. Inspection sign-off is not made by the people carrying the delivery schedule, which is the only arrangement that survives contact with a tight programme.

The principle

An independent body, not a rubber stamp

Our quality assurance department is an independent body. It ensures that quality assurance, environment and safety procedures are respected and implemented throughout the entire cycle of the manufacturing process — not sampled at the end of it.

In practice that means the quality team can stop a job. When it does, the correction happens on our own floor, usually within the same week, because production and quality occupy the same building rather than the same email thread.

  • In-process inspection — a line inspector performs dimensional and visual checking during machining, not only at final stage.
  • Final inspection and test before any item is released to painting and despatch.
  • Certified to ISO 9001:2015 covering quality, environment and safety systems.
  • Client and consultant inspection welcome at our shop, on any working day.

Testing & examination

What we can prove, and how

The scope applied to your order is set by your specification. These are the methods available at our works, and the ones our records are built around.

Hydrostatic Testing

Pressure testing of bodies, vessels and assemblies to confirm integrity of pressure-retaining welds and joints before release.

Radiographic Testing (RT)

Volumetric examination of welds on pipe spools and pressure equipment, revealing internal defects that surface inspection cannot find.

Positive Material Identification (PMI)

Confirms the alloy actually in front of you matches the alloy on the purchase order — the check that catches substituted material before it reaches your plant.

Non-Destructive Testing (NDT)

Surface and sub-surface examination applied across fabricated scope according to the specification, with results recorded against the job.

Dimensional & Visual Checks

Performed in process by the line inspector during machining, and again at final inspection against the approved drawing.

Factory Acceptance Testing (FAT)

Skid packages undergo rigorous FAT including hydrostatic testing, electrical checks and instrumentation calibration before despatch.

Third-party inspection

Third-party inspection can be arranged for pressure equipment. If your specification names a particular inspection agency, tell us at enquiry stage so the cost and the hold points are written into the quotation rather than negotiated afterwards.

Designed in, not inspected in

Details that decide service life

Most strainer failures are not dramatic. They are a seat that never sealed properly, a cover nobody could lift safely, or a body that rusted because it left the shop unpainted.

Precision-machined seats

Y-strainers are built with precision machined seats. A seat that is nearly right is a bypass path, and bypass defeats the entire purpose of fitting a strainer.

Corrosion protection from day one

All cast iron and carbon steel units are epoxy painted to resist rust. Ductile iron valve bodies carry an epoxy powder coat on both internal and external surfaces.

Covers people can actually open

Bolted, hinged, clamped, davit lifting device or other lifting arrangements, so removal of large heavy covers is safe and efficient rather than a two-person struggle.

Installation-friendly ends

Threaded and socket weld end connections are given hex ends for easy installation, and many models carry gauge taps as a standard feature.

Blow-off drains

A standard blow-off drain connection extends the interval between cleanings, and on cone-bottom baskets allows clean-out without removing the screen or interrupting flow.

Material traceability

Castings drawn from our own stores with traceability maintained through machining, so PMI results and material certificates line up with the item on your dock.

Records

What travels with the equipment

Documentation is part of the product. An item that arrives without its records creates work for your QA team and delays your own handover, so ours goes out complete.

  • Nameplate and marking on every item, applied before painting and despatch.
  • Test records for the tests specified on your order.
  • Material certification as required by the specification.
  • Inspection reports where third-party or client inspection has been carried out.

If your project requires a specific documentation format, dossier structure or numbering convention, send it with the enquiry rather than after the order — retrofitting a dossier is the slowest part of any handover.
