Profile

Sandvik Powdermet focuses on materials technology. It develops, produces and supplies hot isostatic processed powder metallurgy components. The division employs 13 persons in Surahammar, Sweden.
Sandvik Powdermet is the world leading company to service you with Powder Metallurgy (PM) Hot Isostatic Processed (HIP) Near Net Shaped (NNS) components ranging from 100g to 15t
in high alloyed steels, stainless steels, Ni and Co
base alloys and Metal Matrix Composites (MMC).
Our business vision is to lead the expansion of HIPed NNS compo­nents through active developing and marketing components with complex geometry, short reliable delivery combined with design flexibility and tailor-made properties.
Sandvik Powdermet has achieved a foothold in the offshore components market, utilizing its net shape expertise to produce complicated parts for subsea development projects. Areas of importance are components for multi-fluid analysis, wye-pieces for pipeline installations, manifolds for topside and subsea installations, valve bodies for choke and control valves, and swivels for FPSOs.
The entire production flow is subjected to comprehensive quality assurance system in compliance with the ISO 9002 standard.
Sandvik Powdermet also operates an environmental management system in compliance with ISO 14001 2004 and occupational health and safety in compliance with OH SAS 18001.
MANIFOLDS
Manifolds are used for collecting oil/gas from well heads as well as for water injection. They are subjected to sour service and high pressure, and therefore high mechanical strength and corrosion resistance are required characteristics of the material used in the manufacturing of manifolds.
Sandvik Powdermet uses the P/M-HIP manufacturing method to ensure the required high mechanical strength of the components. The material used are duplex, super duplex, austenitic and Ni-based alloys, the best choice in our service.
FPSO SWIVEL COMPONENTS
Swivels components used in FPSO systems with internal passages for oil/gas, water injection and power connections are heavy-duty items with considerable added value.
Duplex stainless steel multi-phase swivel components use the versatility of the P/M HIP technique, which is capable of accommodating multiple flow paths.
WYE-PIECES
A 40% weight reduction was achieved on the wye-piece using Hot Isostatic Pressing (HIP). The virtues of hot isostatic pressing in the manufacture of high-grade steel components is winning the confidence of new offshore customers for Sandvik Powdermet, the recognized P/M-HIP specialist.
A large subsea wye-piece in UNS S31803 duplex stainless steel was a demanding order, requiring a great deal of design work, including
stress analysis and 3D finite element analysis.
Made conventionally by casting or forging, the piece would have had to be oversized and would have likely weighted some 3.5t to withstand the 250bar design pressure. But the P/M-HIP process permits a significant degree of optimization, and the finished piece weighed only 2t.
