Sandvik achieves NORSOK approval for its Alloy 625 Hot Isostatic Pressed (HIP) products
August 24, 2016
Sweden’s Sandvik AB has announced that it recently achieved NORSOK approval for its Alloy 625 Hot Isostatic Pressed (HIP) products. Sandvik is the only company to have achieved the NORSOK qualification for HIP products in this material.
“This is an important step towards providing customers with increased design flexibility and manufacturing advantages especially for subsea systems,” stated Mats Petersson, Sandvik Product Manager, HIP products, Oil & Gas.
In many oil and gas projects the NORSOK qualification is a prerequisite, “This qualification will drive product differentiation and means that customers in this sector will no longer have to seek other, less effective forms of manufacture. It opens up more opportunities where we can satisfy the complex nature of the products along with the exceptional corrosion resistance and inbuilt strength of the HIP process,” stated Petersson.
Hot Isostatic Pressing facilitates the manufacture of products with irregular shapes and complex geometries such as subsea wye pieces, manifolds, tees, swivels, valve bodies etc., to near-net-shape. Costly operations such as machining and welding are greatly reduced, process safety improved and material properties enhanced. It also results in products having isotropic properties, the ability to withstand complex multidirectional loads, contributing to a lighter, more precise and stronger product.
Sandvik advanced metal powder technology is available in a full range of stainless steels, duplex and super-duplex material grades. These offer excellent resistance to corrosion and hydrogen induced stress cracking (HISC) making them ideal for subsea offshore oil & gas operations.
“Sandvik’s industry-leading metallurgical competence can help create unique customer value, setting industry standards in Powder Metallurgy based applications,” added Petersson.
ONS 2016 Conference and Exhibition, August 29 – September 1, Stavanger, Norway
Sandvik will showcase its extensive range of complex components for oil and gas applications, using Powder Metallurgy HIP technology, on its stand at ONS 2016: Swedish Pavilion, Booth 6. The HIP products are part of the wide Sandvik portfolio of advanced materials for the oil and gas industry.
