Production

Drawings
Drawings can be accepted in any standard CAD format or on paper. They are then used to program our waterjet cutting equipment. Comprehensive quotations can be supplied on receipt of full drawings or assistance can be provided with tank design.

Fabrication
Waterjet cut sheet aluminium or 316 stainless steel are used for the main body and ends of the tank. Main corners are usually radiused for strength and CNC shaped. Baffles are made as required with punched holes. Sender and fill / pick-up / balance ports are CNC machined as required.
 
       
 

Welding
Tanks are all then individually hand welded, either TIG or MIG, by coded and time served welders in dedicated welding bays with cranes and other material handling equipment as required by the bulk of the tank. A rolling program of updating the welding equipment to the latest synergic MIG sets is now underway for those tanks that require MIG welding. One welder completes every tank thus ensuring pride in the finished article.

Quality Control
Dimensional checks are then performed and every tank is pressure tested to ensure that there are no leaks. After pressure and ‘drop’ testing, each tank is numbered, a full record of which has been kept since 1981 to ensure traceability and easy replication in the unlikely event of a replacement being required.

Finishing
Both aluminium and stainless steel tanks can be powder coated or painted as required in a selection of popular colours.

Carriage
Tanks are packaged as required complete with gauges, straps and any fittings specified. Carriage is either on one of our own vehicles or a Nationwide overnight pallet carrier.

 

The company has ISO 9001 accreditation and tanks are made to ISO 10088 and Lloyd's approvals, but we can also accommodate other standards such as CAP437 & 434 for Aviation Fuel Storage and Der Norsk Veritas.
