With decades of metallurgical expertise and in-house tooling capabilities, our Coatesville, PA facility produces manways built to withstand extreme pressure, temperature, and corrosive conditions. Discover why aerospace, defense, and energy sectors trust MTS Forge for critical access components.
Comprehensive forged manway solutions and complementary capabilities for industrial vessels across demanding sectors.
Manufacturing of forged manway hatches for industrial pressure vessels and containment systems. Produced to exact dimensional and material specifications for power generation, chemical, and nuclear applications requiring reliable access points.
In-house hot and cold plate forming services supporting manway hatch production. Internal tooling design capability enables a diverse range of shapes at competitive cost without outsourcing to third-party vendors.
Post-forging rough machining applied directly to manway components to achieve near-net shape, removing flash and surface irregularities. Reduces lead times and eliminates the need for a separate machining vendor.
In-house normalizing heat treatment for forged manway components, performed at our Coatesville facility. Produces refined, uniform microstructure with improved tensile strength, toughness, and machinability for downstream processing.
Contour forging services using specialty materials including duplex stainless steels like Ferralium 255, extending material options for manway hatches operating in highly corrosive or extreme-pressure environments.
Custom-forged manway configurations tailored to exact customer specifications. Combining cutting-edge technology and time-honored craftsmanship, every custom piece meets the highest standards of durability — Made in America.
Manway hatches must perform flawlessly in environments where failure is not an option — high-pressure vessels, nuclear containment systems, and chemical processing units across Pennsylvania and beyond. MTS Forge produces forged manways with complete traceability under a rigorous Quality Assurance Program, combining in-house tooling design, rough machining, and heat treatment to deliver components ready for immediate integration. Our metallurgical expertise ensures every hatch meets exact dimensional, material, and mechanical property requirements.
