Family-owned for three generations, JMW takes pride in delivering quality ASME Pressure Vessels and API Erected Tanks throughout the United States. ASME Pressure Vessels
JMW LLC was granted certification in the 1960’s to design and fabricate vessels in accordance with the A.S.M.E. As such JMW has extensive knowledge and experience utilizing and applying this code. JMW possesses both the A.S.M.E. “U and “R” stamps which grants certification to design and fabricate not only new vessels, but also allows for the modification of existing vessels. Review and re-certification of JMW’s “U” and “R” stamps is performed every three years by the governing authority of A.S.M.W. Boiler and Pressure vessels. Design
For over 30 years, James Machine Works has used the auto-cad design drafting program. Auto-cad is a proven industry standard for precise measuring and laying out of equipment and components in the chemical, pulp and paper, and petrochemical industries. JMW’s design staff is comprised of 5 engineers, 3 of which are registered professional engineers, and a team of design professionals. JMW's design fundamentals encompass engineering software that includes FEA analysis, COMPRESS, and RISA 3-D. Shop Fabrication
Even your largest projects can be handled in James Machine Works' 140,000 sq. fabrication facility. Shop fabrication is implemented using automated equipment. Two CNC Plasma Cutting Tables (20x80' and 12x40') are utilized to cut special shapes such as cone layouts, compression rings, and other miscellaneous items. Files are transferred to the computer-aided system from the engineering department. (The CNC files are generated on computer-aided systems by the engineering department.) The Messer Plasma Cutting Table is also used for squaring, cutting, and beveling shell cylinder plates. Plate rolling capabilities include materials up to 1 1/2" thick by ten foot wide. The roll capacity does not limit JMW from fabricating heavier wall vessels on tanks. We can subcontract the forming if necessary. A 750 ton by 10-foot long hydraulic press brake provides for the special forming of cones and transitions. Shearing capabilities are 3/8" thick by ten foot. Our JMW owned angle iron forming rolls can handle all sizes of angle, including pipe coils and heavy bar. Automatic submerged arc welding is utilized to weld longitudinal and circumferential seams of pressure vessels. Other welding processes include GMAW SMAW, FCAW, SAW, GTW, and EGW. Weld processes are selected as approved by the customer and as required by metallurgy. 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. From smaller vessels completely fabricated at our facility, to massive tanks requiring on-site erection, James Machine Works has the equipment and experience to get the job done right and on time. On-site Erection & Installation
Our field installation crews keep safety as their main concern as each component is skillfully erected and installed. Every aspect is checked and rechecked to ensure proper start-up and trouble free operation at your facility. Maintenance & Repairs
For repairs, retrofits, maintenance, and redesigns, James Machine Works is ready to respond quickly. JMW's reputation for service is unmatched. From the largest projects to the smallest, our goal is your complete satisfaction while keeping safety as our priority. Our mobile cranes and equipment, field crews, and full-time employees are geared to provide the highest levels of quality and customer satisfaction. JMW's staff includes API-653/CWI inspectors to verify quality assurance. Painting
James Machine Works applies the finishing touch with professional quality. A 20'X20'X60' metallic grit blast chamber is the cornerstone of JMW's 50'X200' state-of-the-art painting facility. An 80'X300' exterior lot is used for garnet and black beauty blast media. Two 20-ton overhead bridge cranes serve this facility. In House Machine Services
