The company is a full turnkey contractor offering engineering, fabrication, coating, erection, and startup under a single contract. MMI's tank capabilities span API 650 field-welded oil storage tanks, AWWA D-100 water storage tanks, NFPA 22 fire protection water tanks, factory-coated bolted tanks for remote sites, API 12F and UL 142 shop-built tanks, and ASME pressure vessels holding S, U, and National Board R stamps. They also fabricate clarifiers, thickeners, hydro-pneumatic tanks, silos, hoppers, and bins for water and wastewater treatment. Their fabrication shop houses plasma cutting tables up to 13x60 feet, plate rollers handling 1-7/8-inch thickness, a 750-ton press brake, and overhead cranes to 7.5 tons. In-house coating application covers epoxy, polyurea, glass-fused-to-steel, zinc-rich primers, NSF/ANSI 61 potable water coatings, and high-temperature systems. MMI crews hold OSHA, MSHA, and HAZWOPER certifications with AWS-certified welders qualified in all processes and positions.
Key Products
Field-welded steel storage tanks designed to API 650 standards for crude oil, produced water, and hydrocarbon storage in petroleum and energy applications.
Inspection, repair, and rehabilitation services for existing aboveground storage tanks to bring them into API 653 compliance and extend service life.
Welded carbon steel water storage tanks designed to AWWA D-100 standards for potable water, fire protection, and process water in municipal and industrial applications.
Dedicated fire water storage tanks designed to AWWA and NFPA 22 standards for fire suppression systems at industrial, commercial, and municipal facilities.
Factory-manufactured bolted steel tanks for rapid field assembly at remote sites, available in epoxy-coated and glass-fused-to-steel options for water, wastewater, and industrial storage.
Shop-fabricated steel storage tanks built to UL-142 standards for aboveground storage of flammable and combustible liquids at fixed locations.
Code-stamped pressure vessels designed and fabricated to ASME standards with R, U, and S stamps for applications requiring pressure containment in process industries.
Pressure vessels that combine water and compressed air to maintain system pressure in water distribution and booster pump applications.
Custom-fabricated bulk storage vessels for dry granular materials, powders, and aggregates used in industrial, agricultural, and mining operations.
Circular or rectangular sedimentation tanks for water and wastewater treatment that allow suspended solids to settle by gravity for removal from the process stream.
Gravity thickening tanks that concentrate wastewater sludge by allowing solids to settle and compress, reducing sludge volume for downstream processing.
