Capstone Equipment

What Capstone Equipment does

Capstone Equipment, LLC is a Prospect, Kentucky-based engineering, fabrication, and field services company that delivers turnkey mechanical and structural projects for the power generation, oil and gas, and heavy industrial sectors. Its core offering is organized into four service lines: Field Services (on-site construction, maintenance, repair, and replacement for power and industrial plant equipment including gas turbine inlet and exhaust systems, stacks, silencers, power and process piping, and structural work); Engineering and Site Support (ASME Section VIII pressure vessel design, ASME B31.1/B31.3 piping design, ASME STS-1 steel stack design, modular skid and pipe rack design, and project and construction management); Steel Structures (pre-engineered metal buildings, conventional steel buildings, pipe rack enclosures, boiler and HRSG roof enclosures, aircraft hangars, manufacturing facilities, agricultural and custom structures via the Authorized Varco Pruden Builder network); and Fabrication (steel stacks, inlet and exhaust ducts, structural and access steel, pipe racks, acoustical silencers, ASME pressure vessels and heat exchangers, access doors, above ground tanks, and specialty equipment). Manufacturing execution leverages a global fabrication partnership with Forney Corporation's 100,000 sq ft ASME B&PV-certified facility in Monterrey, Mexico, supplemented by 3D engineering documentation and bilingual Chinese/English deliverables for international projects such as an Iraq combined cycle power plant.

The company is a 100% woman-owned LLC holding WBE and WOSB certifications, with professional engineering licenses in 13 U.S. States and Alberta, Canada. Its go-to-market is direct enterprise field sales targeting utility operators, project developers, and engineering firms in power, process, chemical, steel, pulp and paper, and manufacturing; named enterprise customers include Duke Energy, AFF, Braden, Ajax Tocco, Continum, Atlas Co, HRST, and Remington. Revenue is generated through project-based, quote-driven contracts for engineering services and one-time fabrication and construction engagements, with no publicly disclosed pricing tiers. Industry positioning is built on ASME, AISC, API, and AWS D1.X code compliance expertise, 40+ years of combined experience, and a turnkey delivery model spanning design through fabrication to field construction, complemented by MBCEA industry association membership and the Varco Pruden Authorized Builder relationship.

The company operates from a corporate office at 7013 Windham Parkway in Prospect, KY, and conducts field services across the United States with international engineering project capability. Predecessor entity Kapsalis & Kapsalis, Inc was founded in Augusta, GA on February 4, 1985; the business was acquired and rebranded to Capstone Equipment in November 2017 by Carol Kapsalis (CEO), with Stephen Kapsalis joining as President in November 2016. Headcount is reported in the 11-50 range, and no external institutional funding, parent company, or acquisition activity is disclosed.

Others

• Forney Corporation: Capstone's Monterrey fabrication partner producing ASME piping, skids, pressure vessels, stacks and AISC structures; an enabling supplier rather than a competitor, but core to the same product categories.

Broad incumbents

• Babcock & Wilcox Enterprises: Established supplier of boilers, pressure parts and environmental equipment for power and industrial plants; overlaps Capstone's boiler/pressure vessel and stack work but as a large diversified OEM.
• Team Inc. (Team Industrial Services): Provides industrial field services, inspection, repair and maintenance for power and process plants, overlapping Capstone's field services and turnkey maintenance offerings across a broad footprint.
• Matrix Service Company: National industrial engineering, fabrication and field-construction contractor serving power, energy and storage sectors — same turnkey mechanical/structural model as Capstone but at far larger scale.
• Matrix PDM Engineering / CB&I Storage Solutions: Engineers and fabricates heavy-gauge storage tanks and structural steel for energy and industrial facilities, overlapping Capstone's above-ground tank and fabricated structural metal lines at larger scale.

Direct peers

• Nooter/Eriksen: Engineers and fabricates HRSGs, pressure vessels and related power-plant heat-recovery equipment, directly overlapping Capstone's ASME pressure vessel and combined-cycle plant work.
• Braden (CECO Environmental): Designs and supplies gas turbine inlet and exhaust systems, filter houses, silencers and diverter dampers for power plants — the same GT inlet/exhaust and silencer scope Capstone provides. Braden also appears as a customer, underscoring category overlap.
• Hamon Group: Designs and builds industrial stacks, chimneys, cooling systems and air-quality equipment for power plants, directly overlapping Capstone's steel stack and ductwork design/fabrication niche.
• Vogt Power International: HRSG and power boiler design/fabrication firm serving gas-turbine combined-cycle plants; Capstone's President previously led it, and the two overlap in power-plant pressure-part fabrication.
• Graham Corporation: Manufactures heat exchangers, vacuum and heat-transfer equipment and fabricated pressure vessels for energy and industrial markets, overlapping Capstone's ASME vessel and heat-exchanger fabrication.
