Hystat now has over 50,000 sq ft of production floor at its disposal.

We now have over 50,000 sq ft of production floor at its disposal. Using a team of highly skilled engineers, a combination of state of the art three, four and five axis CNC machines and conventional machines, we are able to manufacture components in the most efficient method dependant on the complexity and batch size.

These machines are backed up by a CNC co-ordinate measuring machine (2m x 0.9m x 0.9m) and a three seat fully graphical computer programming system. Our lathes can turn in house from 1mm to 1200mm dia and up to 8000mm in length.

Our machining centres and Horizontal borers can handle prismatic parts up to 1.6m cube and 5 ton in weight.

Welding & Fabrication

Our in-house welding department features both MAG and TIG welding processes. We have a wide array of existing PQRs all tested in accordance to BS EN ISO 15614-1:2017 level 2 featuring IACs approval. Additional testing has also been undertaken to individual IACs rules, which tend to be more demanding than the ISO standard alone.

Boasting a multitude of material ranges for both carbon and stainless steels in a wide array of thicknesses and diameters. Including, but not limited to material groups 1, 2, 3, 8 & 11 within BS EN ISO 15614. Covering barrel diameters 20mm to unlimited with wall thicknesses ranging from 4 to 120mm. Plate thicknesses up to 300mm.

Our welders are tested in accordance to BS EN ISO 9606-1:2017 and compliment identical qualification to all of our PQRs. They hold qualification to our full PQR size range in butt, fillet and branch welds in PA, PB & PC positions.

Welding documentation is available upon request.

With use of overhead cranes, weld manipulators, bespoke handling equipment we have the ability to handle a vast range of projects.

Utilising both in house and external NDE, CSWIP qualified inspectors we are able to ensure our welding is of the highest quality.
