Welding solutions for refineries, rigs and process plant

Oil and petrochemical work runs hot, wet and abrasive at the same time: reformer tubes creep at temperature, process streams eat valve seats and apparatus, and drilling tooling meets rock from the first metre. Pick an area of the refinery to see which components wear, how they fail, and the STANVAC range that puts them back in service.

How oil and petrochemical components fail
  1. Heat & creep

    Reformer tubes and furnace internals held at temperature until the wall sags and thins.

  2. Carburisation

    Hydrocarbon streams carrying carbon into hot tube and furnace metal until it turns brittle.

  3. Corrosion

    Sour, salt and chemical streams attacking valve seats, screws and process apparatus.

  4. Abrasion

    Rock cutting boring bits and drilling tooling away from size on every metre drilled.

We’ll send the procedure.

Base metal, service temperature and the stream it runs in — an application engineer comes back with the consumable, the parameters and the expected life gain.
