St Louis Pipe & Supply

What St Louis Pipe & Supply does

St. Louis Pipe & Supply is a privately held, family-owned industrial pipe, valve, and fittings (PVF) distributor headquartered in Chesterfield, Missouri, operating a second warehouse in Pasadena, Texas and leveraging a Houston-based sister company (Worldwide Pipe) for warehousing and global logistics. Founded in 1987, the company stocks carbon, alloy, chrome, stainless, and nickel-alloy pipe, fittings, flanges, valves, structural steel, tubing, OCTG, and fasteners in diameters from ⅛" to 60", meeting ASTM, ASME, ANSI, and API specifications, and supports this inventory with in-house fabrication, threading up to 12", and coating services (FBE, 3LPE, galvanizing, zinc plating).

The company's revenue model is project-based, one-time B2B sales priced via custom quote (US dollars, FOB shipping point), with goods purchased from global manufacturers and shipped to the customer's nearest port worldwide. The primary customer segment is the oil and gas industry (OCTG for drilling, casing, tubing meeting API specs), with secondary verticals including industrial plant and petrochemical processing and construction/infrastructure. Customer engagement is sales-led, driven by direct phone/email contact, website-driven quote requests, and a content library of technical specifications and grade charts, with no disclosed digital advertising or e-commerce channel.

Governance is family-controlled (CEO Gary Walshauser, President Tim Walshauser), with 51-100 employees and no external investors, public listing, or disclosed financial metrics. The firm self-describes as one of the largest international PVF suppliers in the United States, with operations active as of 2025 per current website content and specials.
