What Plant Maintenance Service does

Plant Maintenance Service Corporation (PMSC), founded in 1967 and headquartered in Millington, Tennessee (Memphis area), is a privately held industrial fabricator and field services provider. The company custom-designs and manufactures ASME Section VIII Division 1 process equipment, including shell-and-tube heat exchangers, pressure vessels, columns and towers, reactors (including clad and half-pipe jacketed configurations), and storage tanks. Its shop footprint spans 50 acres and more than 90,000 square feet of covered space across three manufacturing facilities, supported by a separate field services location. Engineering design relies on Aspentech (B-JAC) software for TEMA-type heat exchangers and CNC drilling centers, and quality assurance is backed by comprehensive non-destructive examination including helium mass testing, radiography, ultrasonic testing, and positive material identification. The company holds ASME U, S, and R Stamps, NBIC R certification, and TEMA Class B/C/R certifications, and has earned twelve consecutive Liberty Mutual Safety Awards.

PMSC's commercial offering combines one-time capital-equipment sales with professional services revenue from field construction and 24/7 emergency repair work for plant shutdowns. Customers are industrial operators and engineering, procurement, and construction (EPC) firms in chemicals, petrochemicals, power, agriculture and oilseed processing, pulp and paper, and water technology, with a named enterprise roster that includes BASF, DuPont, Cargill, Bunge, Conoco, General Electric, Bechtel, Jacobs Engineering, Fluor, and International Paper. GTM is enterprise field sales executed directly with plant operators and EPC intermediaries, with quote-based pricing on custom-engineered scope and no public pricing or revenue disclosure.

The operating model is anchored by a 57-year safety and emergency-response culture; the company highlights reference projects such as the world's largest unsaturated polyester resin reactor and a 28-day emergency VCM Column turnaround. Ownership is independent (President Jeff Turner, VP of Field Services Rusty Perry), with no institutional investor, parent company, or M&A activity disclosed in the source material. Service geography is concentrated in the Southeastern United States, and the company maintains dedicated job-listings infrastructure for ongoing workforce addition.
