AR-20

20 litre stainless steel air reservoir

Twenty litres, stainless, and deliberately left uncoated, because on this vessel the weld is the finish. Nothing is filled, painted or hidden. What you see is what came off the bench.

A dash means we have not published that figure yet — not that it does not exist. Ask and we will send the drawing and the test record for the exact build you need.

WHERE IT IS USED

  • Compressed-air systems where the vessel is washed down or works in a corrosive atmosphere
  • Rail and road vehicle air-brake reservoirs
  • Instrument air on packaging and process machinery
  • Air suspension reservoirs on buses, trucks and trailers

HOW IT IS MADE AND PROVED

Welded to a qualified procedure

Every joint runs to a qualified welding procedure — WPS and PQR — by a welder qualified to run it. Welding is carried out under ISO 3834.

Inspected and tested before it ships

Visual inspection of every weld, dimensional inspection against your drawing, and leak and pressure testing on vessels. The result is recorded against the job number, and the documentation pack ships with the goods.

Traceable to your job

Plate and fittings are booked in against the job, not against a shelf, so what went into your vessel stays traceable to your vessel.

BEFORE WE QUOTE

Send what you have. We can help clarify the remaining details.

  • Your drawing or installation envelope, intended use and quantity.
  • Required material, finish, connections and mounting arrangement.
  • For pressure vessels: working pressure, operating temperature and applicable design or inspection requirements.
  • Target delivery date and the documents your purchasing team needs.

Frequently asked

Is the 20 L reservoir supplied uncoated?
Yes. It is deliberately left bare, because on this vessel the weld is the finish. Nothing is filled, painted or hidden, so the girth and longitudinal seams can be inspected directly.
What working pressure is it built to?
It is built to the pressure you specify. Send the working and test pressure with your enquiry and we will confirm plate thickness, head form and test regime before quoting.
Can you supply a test certificate?
Yes. Every vessel is leak and pressure tested in house and the result is recorded against the job number. The documentation pack ships with the vessel.
