We have been forging a variety of compression fittings for many years in a range of materials including carbon steels, stainless steels, nickel alloys and copper nickels. Forged elbows, forged tee pieces, forged cross pieces. Most of our fittings are produced as blank forgings for our Customer to finish machine.

In addition to compression fittings, our NORSOK QTRs cover us to manufacture a range of forged parts including flanges, nozzles, yokes and valve bodies.

W H Tildesley has been forging components under NORSOK qualifications since 2008.

We run a tightly controlled materials planning, scheduling and quality system that gives us complete traceability of all materials and processes with a minimum of fuss.

During their visit to our UK Forging site, Aker Solutions were very complimentary about W H Tildesley’s manufacturing forging facility and business systems.

W H Tildesley uses a closed die drop forged process to produce forgings at its site in the West Midlands, UK.

We have been serving the oil & gas market for many years and are particularly competitive on small and medium quantity runs. Our commitment to the principles of LEAN manufacturing helps to makes us proficient in setting up to produce just a handful of components, if required by our customer. We also produce higher quantity runs up to several thousand. For some customers, we hold stock at our site which then gets called off to schedule or order.

Parts can be supplied as-forged, proof machined or finish machined from a few grams up to 70kg finished forged weight.
