What Carpenter & Paterson does

Carpenter & Paterson, Inc. is a U.S.-based manufacturer of engineered pipe supports and pipe hangers, founded in 1908 in Boston and headquartered in Woburn, Massachusetts. The company designs, engineers, fabricates, and distributes pipe support systems including variable spring supports (five travel series, up to 10 inches of movement, up to 50,000 pounds of load), constant spring supports, static and dynamic restraints, pre-insulated supports, and custom-fabricated structural steel components. Manufacturing is conducted at two ISO 9001:2015-certified plants in Donora, Pennsylvania and Waggaman, Louisiana, with regional sales, engineering, and inventory held across nine North American branch offices. The company is a wholly-owned subsidiary of UK-listed diversified infrastructure group Hill & Smith Plc and operates alongside sister brands Bergen Pipe Supports (joined 1964) and FM Stainless under the umbrella brand "The Paterson Group." Additional proprietary product lines include the Witch brand of plumbing-specialty pipe hangers and MULTI-STRUT channel framing systems.

Carpenter & Paterson serves enterprise customers across commercial construction, water and wastewater treatment, oil and gas refining, power generation, data centers, and transportation infrastructure. Named end customers include NYC DEP (Newtown Creek and Croton water treatment plants), Marathon Petroleum, ExxonMobil, Shell, BP, Citgo, Calpine, Entergy, PSEG, Tampa Electric, and EMC Corp, plus landmark transportation infrastructure such as Boston's Zakim Bridge. Differentiated technical capabilities include Registered Professional Engineer-stamped designs, full pipe stress analysis using Bentley AutoPipe v9.3, and fabrication compliance with MSS-SP 58, ASME B31.1/B31.3/B31.9, and AWS D1.1 codes. Manufacturing capital equipment includes robotic welding cells and a Peddinghaus HSFDB-C plate processor capable of handling plate up to 4 inches thick with 45-degree beveling.

The company's revenue model combines one-time sales of manufactured pipe support products, project-based custom fabrication, and professional engineering services (estimating, design, pipe stress analysis, walkdown/inspection, and value engineering). Pricing is quote-based and project-specific; multi-year contracts are typical, and next-day delivery is available from all branch locations supported by company-owned delivery fleets and freight logistics. In 2023 the company shipped 50,223 engineered pipe supports, produced 11,330 unique detail drawings, and shipped 10.5 million pounds of material — up from 44,764 supports in 2022 and 38,721 in 2021 — indicating sustained volume growth in advance of its 2024 Waggaman facility expansion targeting EV, computer, and battery manufacturing customers.

Products and services

• Variable Spring Support A spring-loaded device used for the support of piping and equipment where normal vertical movement is anticipated. Manufactured in five different Travel Series allowing up to ten inches of movement and twenty-five different sizes allowing up to 50,000 pounds of load.
• Constant Spring Support Spring hangers used on systems where there are large vertical thermal movements, critical stress conditions, or a combination of both. Used at locations to avoid transfer of load from support to support, or to connecting equipment such as boiler nozzle or ductwork connections.
• Static & Dynamic Restraints High-quality restraint assemblies and devices in various types, sizes, and configurations designed to provide safe and efficient equipment operation with customizable options.
• Pipe Support Hardware Standard hardware components specified and installed on major water treatment, pharmaceutical, process piping, petro-chemical, hospital, and school building projects throughout the world.
• Pre-Insulated Pipe Support Insulated pipe supports designed to prevent direct heat transfer between pipes and their supports, reducing heat loss due to conduction at each support point. Available with HD PUF and Calcium-Silicate insulation for extreme temperature applications.
• Custom Fabrication Fully coordinated service including stress analysis of pipework, hanger selection, design and detailing, 3D CAD modelling, manufacturing and contract management for custom pipe support solutions.
• Pipe Shoes, Slides & Guides Pipe shoes, slides, and guide products for pipe support systems, including large-diameter Type 316 Stainless Steel slide supports and guides for wastewater treatment and process piping applications.
• MULTI-STRUT Channel Framing Systems Proprietary channel framing systems product line cataloged as Catalog 09MS, used for pipe support framing applications with customizable configurations.
