Sandvik achieves NORSOK approval for Alloy 625 hot isostatic pressed (HIP) products

Having recently achieved NORSOK approval for its Alloy 625 hot isostatic pressed (HIP) products Sandvik will showcase its expertise in the production of complex components for oil and gas applications, using powder metallurgy HIP technology, on its booth at ONS 2016.

Sandvik is the only company to have achieved the NORSOK qualification for its HIP products in Alloy 625, explained Mats Petersson, Sandvik Product Manager, HIP products, Oil & Gas. This is an important step towards providing customers with increased design flexibility and manufacturing advantages especially for subsea systems. 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.

In many oil and gas projects the NORSOK qualification is a prerequisite, the only options being to use other manufacturing methods, such as forging where there are few qualified operators, or to seek a complex deviance. Working with Sandvik makes the process straightforward and can accommodate the most complex of designs using HIP technology, added Mats 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 and gas operations.

Sandvik’s industry-leading metallurgical competence can help create unique customer value, setting industry standards in powder metallurgy based applications, concluded Mats Petersson.

HIP product examples will be displayed in the Swedish Pavilion, Booth 6, at ONS 2016. The HIP products are part of the wide Sandvik portfolio of advanced materials for the oil and gas industry. Sandvik works with all major oil and gas companies and fabricators to solve challenges relating to deep, hot and sour wells where corrosion, cost-efficiency, weight savings and safety are critical.
