The trend in the O&G industry is for using higher strength materials for high pressure – high temperature service, however as strength increases materials may also become more susceptible to ambient temperature failure mechanisms...

... this frequently entails testing under conditions of High Pressure/High Temperature (HPHT) with sour gas to simulate a range of oil field environments and conditions to investigate blistering resistance, chemical compatibility and life prediction/ageing studies. The objective of this paper is to consider some...

... components in the Oil and Gas industry. The properties of most value of electroless Ni for the industry are the thickness uniformity, excellent corrosion resistance and abrasion/erosion resistance. In this article we demonstrated that Ni-based MMnCs outperform conventional electroless Ni and hard chromium...
