ASME Flanges
Manufacturing of forged flanges up to 14 inches in size with complete traceability and a rigorous Quality Assurance Program, primarily serving commercial nuclear and power generation applications requiring ASME compliance.
Precision-forged ASME flanges engineered for the uncompromising demands of pressure vessel connections in nuclear, power generation, and industrial applications. MTS Forge delivers full traceability, stringent quality assurance, and decades of metallurgical expertise — ensuring every flange meets code requirements and performs reliably under the extreme pressures and temperatures your systems demand.
Comprehensive forged flange and pressure vessel component solutions manufactured to the strictest ASME and industry standards.
Manufacturing of forged flanges up to 14 inches in size with complete traceability and a rigorous Quality Assurance Program, primarily serving commercial nuclear and power generation applications requiring ASME compliance.
Section III special forgings in 316-L Stainless Steel crafted to stringent standards under Mil I 45208, NCA 3800, and Mil Q9858, ensuring precision and reliability for critical pressure-boundary applications.
Forged manway components engineered for pressure vessel access applications across nuclear, power generation, and chemical processing industries, built to dimensional and material specifications your project demands.
Production of upset forgings, rings, and cylinders up to 26 inches in diameter and 1,500 lbs per piece across nearly all material grades, suitable for pressure vessel connection hardware.
In-house normalizing heat treatment that relieves internal stresses and refines grain structure in forged flanges and pressure vessel components, producing consistent mechanical properties for demanding service environments.
Post-forging rough machining services that bring flange and pressure vessel components to near-net shape, reducing lead times and eliminating the need for a separate machining vendor.
Pressure vessel connections leave no room for compromise. MTS Forge produces ASME-compliant forged flanges up to 14 inches that meet the rigorous quality and traceability requirements of the commercial nuclear, power generation, and chemical processing sectors. Operating from our Coatesville, PA facility since 1986, we combine metallurgical expertise with a comprehensive Quality Assurance Program — covering Mil I 45208, NCA 3800, and Mil Q9858 — to deliver flanges with documented traceability at every stage of production.
