Oil and gas parts,
machined to your standard.
Oil and gas equipment is specified by the operator, not by the machine shop. We machine shafts, flanges, seal seats, housings and non-standard parts to the customer standard — material, threads and sealing faces agreed before the first cut.

The customer standard comes first
Material grade, sealing surfaces and thread accuracy follow the specification you send, not a house preference. Where the standard and the drawing disagree, we stop and ask before cutting. That applies to the blank, the heat treatment and the final inspection alike.
Shafts for drilling and production
Stepped shafts, spindles and gear shafts are turned, heat treated and finished with the journals and threads referenced to one centre line. Long shafts are finished on a steady rest so the bearing and seal seats stay coaxial; threads are checked with the gauge agreed at drawing review.
Flanges and seal seats
A flange is judged by the bolt pattern, face flatness and the fit of the mating seal. We machine the face and the bore from the same set-up where possible, then check the bolt holes against the drawing. Seal seats are finished last so handling does not mark them.
Material verification
Where a mill certificate exists, the grade is read from it and checked on receipt. Where none does, a sample is tested for chemistry and hardness, and the substitute is agreed with you before machining. The certificate travels with the part.
What the shop can hold
Work up to 8 m in turning diameter, shafts up to 12 m between centres, gears up to 8 m outside diameter, and single castings or forgings up to 35 t. Heat treatment and inspection are in the same workshop as the machining.
Inspection and English reports
Dimensional records cover journals, threads, flange faces, bolt patterns and runout. Ultrasonic and hardness results are added where the specification asks for them. Reports can be issued in English for export, and a customer template can be followed if it is sent with the enquiry.
Replacement and one-off parts
Older rigs and production equipment often have no current drawing. Send the worn part or the mating part; we measure the unworn references and issue a drawing for approval. One piece is enough — there is no pattern charge and no minimum order.
Oil and gas questions
- Can you machine to an operator standard rather than your own?
- Yes. Send the standard and the drawing together. Material, threads, sealing faces and inspection are agreed against your document before machining starts.
- Can you work without a material certificate?
- Yes. A sample is tested for chemistry and hardness and the proposed substitute is agreed with you before cutting. The test result travels with the part.
- What is the largest shaft you can machine?
- Up to 12 m between centres, with turning diameter up to 8 m. Send the size and we will confirm the set-up before quoting.
- How long does a replacement take?
- Usually four to eight weeks from the approved drawing, depending on size, material and heat treatment. The date is confirmed with the quotation.
Send the standard, the drawing or the part.
Tell us the equipment, the part and the specification it has to meet. We reply with what we can measure, the material questions we still need answered, and a date.
