THE UNION IRON WORKS

The Union Iron Works specializes in the manufacturing and supply of high-performance plastic piping systems and fluid-handling components for critical infrastructure applications. Their core capabilities center on the production of C-900 DR-14 PVC pipes and fittings, stainless steel tubing, and stormwater management systems, with demonstrated expertise in fire suppression upgrades, water treatment infrastructure, and hydraulic fluid systems. They deliver engineered solutions tailored to military and defense environments, including precision-fabricated piping assemblies for harsh operational conditions and automated flush devices for fluid control systems. Their technical proficiency spans material specification compliance, pressure-rated system integration, and field-deployable infrastructure fabrication, with a focus on durability, leak resistance, and rapid installation in austere locations. The contractor maintains a consistent and exclusive relationship with the Department of Defense, supplying mission-critical piping and fluid system components for base infrastructure modernization, emergency response systems, and utility upgrades across multiple installations. Their work supports installation resilience, water quality management, and fire safety compliance in military facilities, indicating deep alignment with DoD engineering standards and logistical requirements. Industry focus is firmly rooted in plastics pipe and fitting manufacturing (NAICS 326122), with supplementary experience in plumbing fixture trim and fluid power pump systems. This positions them as a niche supplier of durable, non-corrosive piping solutions for defense and industrial applications where traditional metal systems are impractical. Their vertical specialization lies in replacing aging infrastructure with high-density polyethylene and rigid PVC systems engineered for long-term performance under extreme loads and environmental exposure. The Union Iron Works operates as a small, locally based manufacturer in McAlester, Oklahoma, with no federal certifications on record. Their business model emphasizes direct production, rapid turnaround, and tailored fulfillment for government infrastructure projects, establishing them as a reliable regional source for specialized piping components within the defense supply chain.
