Even your largest projects can be handled in James Machine Works' 140,000 sq. ft. fabrication facility. Shop fabrication is implemented using automated equipment. Two CNC Plasma Cutting Tables are utilized to cut special shapes such as cone layouts, compression rings, and other miscellaneous items. The CNC tapes are generated on computer aided systems by the engineering department. The NCR Plasma Cutting Table is also used for squaring and cutting shell cylinder plates.
Plate rolling capabilities include materials through one inch thick by ten foot wide. The roll capacity does not limit JMW from fabricating heavier wall vessels on tanks. We can sub-contract the forming if necessary. Our shop capacity is limited only by the weight handling capabilities of our equipment. Usually this limit can be quickly forseen through our normal bid calculations.
A 400 ton by ten foot long hydraulic press break provides for the special forming of cones and transitions. Shearing capabilities are 3/8" thick by ten foot.
Angle iron rolls provide the forming of rolled angles up to 6"X6"X7/8" angle. Attachments are available for rolling flat bar the hard way and pipe coils through 3 inch Schedule 80 pipe.
Automatic submerged arc welding is utilized to weld longitudinal and circumferential seams of pressure vessels. Other welding processes include semi-automatic Gas Metal Arc and Flux-Cored Metal Arc welding. The conventional manual modes of welding include Shielded Metal Arc and Tungston Inert Gas welding. Weld processes are selected as approved by the customer and as governed by the part to be welded.
Turning rolls are utilized for the manipulation of vessel parts. Fit-up and welding is implemented by the use of turning rolls during each assembly.
