High Pressure Welding Sweden

What High Pressure Welding Sweden does

High Pressure Welding Sweden AB (HP Welding) is a Sundsvall-headquartered, specialized industrial manufacturer and service provider focused on the fabrication, maintenance, and assembly of pressure-bearing equipment for heavy industries. Founded in 2004 and operating as a wholly-owned subsidiary of Instalco since November 2020, the company employs 11-50 people and serves enterprise customers in pulp and paper, mining and metals, power generation, and industrial construction across Sweden, Norway, Finland, and selected international markets.

HP Welding's core technical capabilities span multiple certified welding methodologies — electrode (111), TIG (141), MAG, seal welding (136), and specialized Inconel 625 overlay welding for high-temperature applications — qualified under SS-EN ISO 3834-2, SS-EN 1090-1, ISO 9606-1, and PED 97-23-EG. In-house equipment includes a Pedrazzoli Bend Master 120 IMS CNC pipe bending machine and fully equipped rapid-response containers for global emergency deployment. The company manufactures boilers, tanks, piping systems, panel walls, super heaters, economisers, and steel structures, while also providing on-site construction, assembly, shutdown maintenance, and welding inspection services.

HP Welding operates a project-based B2B revenue model with quote-driven pricing, winning enterprise contracts through direct sales, competitive bidding, and long-term customer relationships. Named customers include Boliden Mineral (E-kaldo furnace hood), SCA (barkpanna panel walls), Norske Skog (Skogn mill pipelines), and ENCE (Huelva 195 t/h power boiler). Revenue is generated across four streams: manufacturing, construction and assembly, maintenance and repair, and inspection/quality services. The company opened a Norwegian branch in September 2024 to systematically serve the Norwegian pulp and paper market.

Partnerships

Four partnerships are on record, tiered core and minor.

• HighCon ABcoreStrategic or Co-development Partner · 27 February 2024HighCon AB collaborated with HP Welding on the SCA Östrand barkpanna project. HighCon handled scaffolding/stellningar while HP Welding managed manufacturing and installation of panel walls. This Instalco-inter-company collaboration demonstrates synergies available within the group for delivering comprehensive solutions to industrial customers.
• InstalcocoreOthers · 26 November 2020HP Welding became part of the Instalco installation group in November 2020. Through this acquisition, Instalco expanded its industrial business area and gained presence along the Norrland coast. HP Welding operates as a subsidiary with local autonomy while leveraging Instalco's scale and resources. Instalco consists of 150+ subsidiaries with 6000+ employees across Sweden, Norway, and Finland.
• European Manufacturing and Workforce PartnersminorStrategic or Co-development PartnerHP Welding has cooperation partners throughout Europe for manufacturing (e.g., subcontractor in Hungary for Boliden E-kaldo hood fabrication) and can mobilize several hundred welders and fitters when needed for large projects. They also have agreements with major manufacturers of boiler parts and steel constructions.
• KiwaminorOthersCEO Rickard Långh came from a role as head of Kiwa's Sundsvall and Östersund offices before joining HP Welding. Kiwa is a testing, inspection, and certification company, and Rickard had HP Welding as a customer in his previous role before transitioning to the manufacturing side.

Direct peers

• Caverion: Nordic/Baltic building and industrial technical installation and maintenance services provider. Comparable in service-led delivery model, presence in Finland/Sweden/Norway, and focus on industrial maintenance, shutdowns, and lifecycle services.
• AF Gruppen: Norwegian-based industrial and civil contracting group with operations in energy, environment, and construction. Comparable in delivering industrial installation and fabrication projects for energy and process-industry customers in the Nordics.
• Bravida: Nordic multi-disciplinary installation and services group operating in Sweden, Norway, and Finland. Closely comparable in business model (technical installation and service for industrial/commercial customers) and overlapping customer base, although Bravida is much broader in scope (electrical, HVAC, etc.).
• Assemblin: Nordic installation and service company operating across Sweden, Norway, and Finland with multi-trade technical services for industrial customers. Comparable to HP Welding as a peer Instalco subsidiary given similar geographic footprint and industrial customer orientation.

Others

• ESAB: Global welding and cutting equipment and consumables manufacturer. Comparable as a welding-industry participant, although ESAB supplies welding consumables/equipment while HP Welding is a downstream welding service provider using such products.
• Lincoln Electric: Global welding products and solutions company. Comparable as a leading welding industry participant; Lincoln Electric primarily supplies welding equipment and consumables, while HP Welding is a downstream service provider, making them adjacent ecosystem peers.

Broad incumbents

• Metso: Global leader in mining, aggregates, and metals processing equipment and services. Comparable because Metso's services business targets similar metals/mining customers (e.g., Boliden-type operators) for maintenance, rebuilds, and process equipment installation.
• Andritz: Global pulp & paper and metals processing equipment OEM that supplies recovery boilers and process equipment to many of the same customers (SCA, Norske Skog, mills in Sweden and Norway) that HP Welding serves with welding, fabrication, and installation services.
• Valmet: Leading pulp, paper and energy technology supplier with strong Nordic presence. Comparable because Valmet supplies and services recovery boilers and power boilers in the same pulp/paper and energy verticals where HP Welding provides fabrication, welding, and shutdown maintenance.
• Sandvik: Swedish industrial engineering group with materials technology, mining, and machining solutions divisions. Comparable due to Nordic industrial base, mining customer overlap, and broad fabrication/machining capabilities adjacent to HP Welding's specialty welding and pressure-equipment work.
