What ORAB does

ORAB Entreprenad AB is a Swedish industrial pipe installation, welding, and machine assembly contractor headquartered in Gävle and operating nationwide since 1996. The company serves large industrial customers (mining, steelmaking, paper/pulp, energy, and research) and Swedish municipalities, executing complex high-temperature and high-pressure pipe systems that require rare certified welding capabilities — including procedures for X10CrMoVNb9-1 low-alloy steel — backed by SS-EN ISO 3834-2 welding quality certification and European Pressure Equipment Directive (PED) Manufacturer status. Its technology stack centers on skilled welding labor (MMA, TIG, MIG, MAG, gas) and two in-house workshops for prefabrication of pipe, sheet metal, and beam structures, with over 5.5 million welding hours produced since founding.

ORAB generates revenue through project-based contracts — competitive tenders, direct negotiations, and repeat awards — covering pipe installation, welding, machine assembly, and prefabricated components. Contracts range from small maintenance jobs to multi-year, multi-tens-of-millions-SEK industrial assignments (e.g., BillerudKorsnäs ~40M SEK, ESS Stage 2 ~220M SEK shared). Go-to-market is enterprise field sales, supported by a network of department offices from Piteå in the north to Lund and Stockholm in the south, and reinforced by long-standing relationships with general contractors Skanska and NCC. Since February 2014, ORAB has been a wholly-owned subsidiary of Instalco AB, a Nasdaq Stockholm-listed installation group, positioning it within the parent's industrial division alongside ~140–180 other companies.

The company launched ORAB Pumpservice in June 2026, a Stockholm-based branch offering pump repair, rental, and service contracts — a recurring-revenue extension of the core project business. With ~130 employees (and equipment to staff ~300), operations span Gävle (HQ), Skellefteå, Piteå, Örnsköldsvik, Karlstad, Lund, Stockholm (Skarpnäck), and Sölvesborg, supported by ISO 9001, ISO 14001, and SS-EN ISO 3834-2 certifications.
