Our Stainless Steel/Duplex/Super Duplex and High Nickel Alloy seamless/welded pipes and tubes meet the most demanding technical specifications and are designed to withstand the most extreme conditions in fields like oil & gas exploration and production, hydrocarbon processing industries, power generation, aerospace, etc. We work with end-users, engineering companies, contractors, and manufacturers to find efficient and competitive solutions for challenging projects.

Applications for Gerab Stainless Steel and Higher Grade Pipes

Oil and Gas Industry

These pipes are used to transport crude oil, natural gas, and other petroleum products from offshore or onshore drilling rigs to refineries and distribution centers. The pipes function well in highly corrosive and aggressive environments such as sour gas and seawater.

Power Generation

They are used in power plants for the transportation of steam and other hot gases. They are also used in boilers, heat exchangers, and other components that operate at high temperatures.

Chemical Processing

In chemical processing, These pipes are used to transport corrosive chemicals and gases. They are resistant to a wide range of chemicals, including acids, alkalis, and solvents.

Food and Beverage Industry

Pipes are used to transport food products and beverages in the food and beverage industry. They are hygienic and resistant to corrosion caused by acidic or alkaline food products.

Marine Industry

Corrosion-resistant pipes are used in shipbuilding and offshore oil and gas production. They are resistant to saltwater corrosion, high pressure, and high temperatures.

Medical Industry

Used in medical equipment and devices requiring contact with bodily fluids or corrosive chemicals. These pipes are biocompatible and resistant to corrosion caused by body fluids and chemicals.

Water Desalination Industry

Stainless steel and higher-grade pipes are an ideal choice for the water desalination industry due to their high corrosion resistance, strength, and durability. They help ensure the efficient and reliable operation of desalination systems, which are essential for meeting the growing demand for fresh water in arid regions of the world.

To ensure a quality supply of pipes, we work with our manufacturers who follow the highest global standards, including:

  • Quality control of raw material
  • Proper melting and casting process
  • Precise rolling and welding process
  • The use of advanced technology
  • Proper annealing and heat treatment
  • Quality testing
  • inspection throughout the manufacturing and supply process

At Gerab, we enjoy close relationships with global manufacturers to supply high-quality stainless steel and all the above grades, including duplex/super duplex, high nickel alloy seamless, and welded pipes.
