Flange Manufacturing
We produce a comprehensive range of carbon steel pipe flanges up to 14 inches, manufactured to ANSI/ASME B16.5 standards with a rigorous Quality Assurance Program ensuring complete dimensional and material traceability.
MTS Forge manufactures carbon steel pipe flanges to full ANSI/ASME B16.5 compliance, backed by nearly 40 years of metallurgical expertise and in-house forging capability. Serving power generation, commercial nuclear, chemical processing, and industrial manufacturing sectors from our Coatesville, PA facility — we deliver dimensionally precise, fully traceable flanges engineered to perform in the most demanding pressure and temperature environments.

From forging and heat treatment to rough machining and full traceability, we deliver complete flange solutions under one roof.
We produce a comprehensive range of carbon steel pipe flanges up to 14 inches, manufactured to ANSI/ASME B16.5 standards with a rigorous Quality Assurance Program ensuring complete dimensional and material traceability.
In-house normalizing heat treatment refines the grain structure of forged flange components, delivering improved tensile strength, toughness, and uniform mechanical properties required for high-pressure piping applications.
Post-forging rough machining brings flanges to near-net shape, removing flash and surface irregularities to reduce downstream processing costs and lead times without requiring a separate machining vendor.
Beyond standard flange profiles, MTS Forge produces custom-forged carbon steel components tailored to exact engineering specifications, supporting special bore sizes, pressure classes, and non-standard geometries for critical applications.
Special forgings crafted to stringent industry standards including Mil I 45208, NCA 3800, and Mil Q9858, supporting nuclear, defense, and high-integrity piping systems requiring full QA program compliance.
Contour forging capability supports complex flange profiles and transition geometries across a wide material range, enabling cost-efficient shape production versus machining from solid bar stock.

We begin by verifying raw material certifications and chemical composition for carbon steel stock, ensuring full compliance with ANSI/ASME B16.5 material requirements before any forging operation commences. Traceability is established at this stage.

Co-Founder
Edward Waddell co-founded MTS Forge in 1986, partnering with Stephen Carr to establish a forging company rooted in technical excellence and long-term customer relationships. Edward brings a metallurgical background and comprehensive knowledge of forging practices that spans nearly 40 years of active industry experience. His expertise spans carbon steel, stainless steel, and high-performance alloy forgings, with particular focus on components destined for high-integrity applications in power generation, commercial nuclear, and defense. Edward's commitment to precision and compliance has been a driving force behind MTS Forge's Quality Assurance Programs, certified to Mil I 45208, NCA 3800, and Mil Q9858, which underpin the company's reputation for fully traceable, specification-conforming flange products.
ANSI/ASME B16.5 is the governing standard that specifies dimensions, pressure-temperature ratings, materials, tolerances, marking, and testing requirements for pipe flanges from NPS 1/2 through NPS 24. A compliant flange is manufactured, documented, and dimensionally verified to meet these requirements, ensuring safe and interchangeable assembly in pressurized piping systems across industrial and commercial applications.
