Pipework and chimney fabrication can be carried out within our workshop or onsite utilising a variety of different materials including stainless and carbon steels and other specialist materials including high nickel alloys. We are also able to offer a pipework and chimney design service, which includes guidance on material specification, designing pipe routes, support requirements and advice on Pressure Equipment Directive (PED) implications.

Additionally we provide a number of services developed to facilitate a successful project. We carry out radiological, hydrostatic, hydraulic and pneumatic testing and inspection. Pipework and chimneys can be thermally insulated and electric trace heated, following installation if required. Projects can be fully documented to suit any requirements to include material and consumables' certification, weld procedures, welder qualification, pressure test certification and non-destructive testing.

The projects that we undertake range from small stand alone pipework fabrication pieces through to high and low pressure system packages including vessel manufacture, steelwork, access and safety systems and a full turnkey project management service if required. In addition we have experience in providing customers with modular pipework solutions such as pre-assembled pipe-racks (PAR’s), pre-assembled units (PAU’s), and skid or container mounted units. These can be manufactured from customer specific designs or developed by our in-house engineering resource liaising with our customer’s engineers.
