Process piping contractor for all industries

What Is Process Piping?

Process piping contractor for diverse industries – HVAC, food & beverage, power generation, and more.

Process piping is a complex system of pipes designed to transport liquids, gases, or media used directly in industrial processes such as oil and gas, heating and ventilation systems HVAC, food production, energy generation, and others. Process piping operates under pressure and various temperature conditions and must comply with strict ISO and ASME standards depending on the region. A complete piping system includes pipes, flanges, valves, elbows, and other fittings made of carbon or alloy steel, selected according to the working medium and design pressure. A process piping contractor is responsible for the fabrication, installation, welding, and testing of these systems, ensuring their safe and efficient operation at industrial facilities.

Certified Process Piping Contractor with 23 Years of Experience

The reliability of any process piping system depends greatly on the experience and certification of the contractor. In industrial facilities, these systems are used to transport fluids operating under high-temperature and corrosion-prone conditions. Only certified specialists can ensure proper assembly , material selection, and installation according to recognized codes and standards such as ASME and ISO. Our company is certified according to ISO 3834-2, employs its own team of certified welders and an in-house welding engineer, and has over 23 years of experience in industrial pipe fabrication and installation. A qualified contractor directly contributes to power efficiency, plant safety, and the long-term performance of every pipe and component in the system.

Our Services within process piping 

1. Prefabrication and Installation We design and prefabricate different types of process piping in our own workshop, including stainless steel pipes, valves, and fittings. Our scope also includes the production of pipe supports and related steel structures. On site, our team performs precise installation, tie-ins, and modifications where existing piping is used or upgraded. All work is carried out by coded welders in accordance with EN ISO 15614, ASME B31.3, and PED standards. 2. Testing and Quality Control We ensure full compliance and reliability through:
  • NDT inspections (VT, RT, and others)
  • Pressure tests for all systems operating under high pressure
  • Complete traceability and welding logs for every pipe and weld joint
  • Pigging service for internal cleaning and system integrity checks
Our approach guarantees safe and efficient operation under demanding pressures and temperatures. 3. Industrial Applications Our process piping systems are used in a wide range of industrial sites, including:
  • HVAC and pump stations
  • Food processing plants, gas, water, and district heating systems
  • The energy sector and renewable energy projects
  • Gas and fluid transport and distribution systems
  • Cooling and cryogen
4. Insulation and Energy Efficiency We provide complete insulation solutions for all piping systems to maintain energy efficiency, reduce heat loss, and protect against corrosion and temperature fluctuations. 5. Rigging and Heavy Equipment Handling Our experienced rigging team performs safe lifting, positioning, and alignment of heavy equipment, skids, and prefabricated piping assemblies. We ensure all rigging operations meet strict safety requirements and support efficient on-site installation.

Prefabrication plays a key role in modern process piping projects.

By producing pipe spools and assemblies in a controlled workshop environment, prefabrication reduces overall project costs, improves weld quality, and significantly shortens installation time on site.

For carbon steel and stainless steel systems, maintaining strict separation between production processes is essential — especially for sanitary or hazardous applications where fluids at high temperatures are handled.
This approach ensures that every component of the process piping system is manufactured in a safe and reliablemanner, fully compliant with international standards.

Prefabrication not only enhances quality control but also guarantees consistent precision across all types of piping, from standard industrial lines to high-purity and pressure-rated systems.

Our Presence

While primarily operating in Scandinavia (Sweden, Norway, and Denmark), we have successfully delivered projects in Switzerland, Austria, and Malta.

Our piping pre fabrication takes place in Estonia, with installation services available across all of Europe.

In other words, we’re ready and equipped to take on projects anywhere in the world—no matter where they’re located!
