Sumitomo Metals Develops New Oil Well Pipe for Deep Water

Sumitomo Metal Industries announced on Wednesday the firm developed c martensitic stainless steel oil well pipe with world top class corrosion resistance and strength. The firm already provides sample of the new pipe, SM17CRS-125 to oil major companies. The firm tries to commercialize the new products in a year to contribute to oil development activity in severe conditions.

The firm expects the new pipe is used for oil development in deep water and severe corrosive environment. The firm offers new option for the development while 13% chrome matensitic stainless seamless pipe is already used for development in severe conditions and dual phase stainless pipe is used for development in deep water. However, the dual phase products with expensive alloy needs cold rolling process for required strength.

The firm succeeded the development of the new 17% chrome stainless pipe 125 kilopounds per square inch of strength. The new pipe has better corrosion resistance in high temperature condition than 13 chrome stainless pipe while the new pipe uses less alloy than dual phase stainless pipe and needs no further process.

Oil and gas development condition gets severer when the resources development already covers almost all traditional fields with easy access. Sumitomo Metals tries to develop required steel pipe with reasonable cost for the development in severe conditions.
