Linepipe

Made for toughest requirements

voestalpine Grobblech GmbH is one of the world’s leading producers of linepipe plates. More than two million tons of sour-gas resistant linepipe plates and very tough linepipe plates for thick-walled deep-sea lines testify to the success of our high-quality products. As a partner to renowned pipe makers we provide outstanding product quality, reliable service and flexibility.

Sour service in deep ocean

Extreme pressures in the deep ocean or sour service - Our linepipe plates can stand even the most difficult conditions. Our products are found in depths of up to 3,000 meters meters below the sea surface and also in the form of sour-gas-resistant linepipes. 

Our linepipe plates provide excellent toughness at low temperatures, best weldability and high uniform elongation for strain-based design. Available up to 18.7 m in length and with a weight up to 20 tons per plate.

Extreme sour service and corrosion resistance for reeling

Roll-bonded clad plates are used for the manufacturing of clad linepipes. In many cases the mixture of oil, gas and a wide range of chemical elements in riserpipes or linepipes used for the transport of oil and gas formes a highly corrosive environment. Only the highest-quality materials are capable of withstanding this aggressive medium. Our roll-bonded clad linepipe plates with corrosion-resistant cladding meet these highest corrosion requirements. 

Extremely low arctic temperatures and harsh environmental conditions

We are there with land lines up to 48 inches (1,220 mm) in diameter.

We provide excellent toughness at low temperatures and our service is tailored to the individual customer from the time the order is received until the material is loaded for on-time shipment and delivery.

Clad linepipe plates

Sourgas resistant plates for tubes

Sourgas occurs in oil and gas production and is considered highly corrosive. Only the best materials can withstand this aggressive medium. As one of the leading suppliers of sourgas-resistant linepipe plates worldwide, we supply roll-bonded linepipe plates with corrosion-resistant cladding for this specific application.

Protective cladding

The base material is decisive in linepipe production. Our roll-clad plates exhibit high strength, good toughness and best corrosion protection as a result of the cladding material. The combination of the X65 product with nickel-based alloy 625 achieves these optimized properties in the material. Our partners process the material into metallurgically bonded linepipe.

Quality defies the elements

The metallurgical bond of the clad linepipe withstands the highest mechanical stress and dynamic loads. These pipes are ideally suited for use in deep-sea pipelines under corrosive conditions.

Reeling and riser pipes 

  • Roll clad plates for pipelines 
  • High corrosion resistance, even for the most demanding sourgas requirements 
  • Reeling of pipelines more efficient and cheaper than welding on board 
  • Roll-bonded plates for metallurgically bonded linepipe to vertical pipelines (risers) 
  • Excellent metallurgical properties of roll-bonded plates for highest compressive strength

Specializing in extreme conditions

Lowest arctic temperatures, highest pressure in the deep sea, acidic media: Even the most adverse conditions cannot harm our linepipe plates. Our plates can be found at depths of up to 3000 meters below sea level as sourgas-resistant linepipe plates or as land pipelines with a diameter of up to 48" (1220 mm). The highest sourgas requirements are met by our roll-bonded linepipe plates with corrosion-resistant cladding. As specialists in modern thermomechanical rolling processes with accelerated cooling, we are one of the world market leaders in linepipe plates. More than 2 million tons of sourgas-resistant linepipe plates and extremely tough linepipe plates for thick-walled deep-sea pipelines are ample proof of our product success.
