13Cr Steel In Oil And Gas In most conditions when the partial pressure of CO2 is above 30psi, carbon steels present high corrosion rates. Steel grades alloyed with high contents of Chromium (Cr), Molybdenum (Mo) and Nickel (Ni) are able to effectively resist corrosion. 13Cr Steel OCTG Pipe made with 13% Chromium (13Cr) are
Differences between Oil Casing Pipe and Oil Drill Pipe There are two main differences between oil casing and oil drill pipe: 1. Different uses; 2. Different materials; 3. Different functions. Petroleum casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire

Duplex Stainless in Oil and Gas The oil and gas industry remains by far the largest user of duplex stainless steels. Standards such as Norsok and NACE (Appendix 1) provide detailed instructions for the selection of materials. They range from carbon steels, stainless steels (martensitic, austenitic, duplex, super austenitic) to nickel-base alloys depending upon
Pipe Coating, Lining and Cladding What is the difference between external pipe coating and internal pipe-lining and cladding? External pipe coatings are used to protect the metal from corrosive environments (3LPE coated pipes are the most common choice). Internal lining (example PTFE) protects the pipe from corrosive fluids. Clad pipes (CRA) have the inner
Drilling, covering, tubing the three phases of a wellbore Product of canvas or gas is a complex, time-and cost-ferocious undertaking, but in principle, every wellbore goes through three phases. Drilling with drill pipes Drill pipes are durable sword pipes that conduct the force to the drill bit. In numerous cases the drill pipe turns
Seamless Steel Tube Cold Treatment Cracks Preventive Ways The seamless steel tubes are mostly medium and high-carbon alloy steels. After quenching, a number of the subcooled austenite isn't transformed into martensite, and it remains within the service state to become retained austenite, which affects the service performance. If it's placed below zero to continue cooling,
Oil & Gas Well Screens Oil & gas well screens combine the hydraulic efficiency of wire-wound screens with the strength of pipe. Because of the strength of the pipe liner, the wrap wires can be smaller, producing a greater open area. The longitudinal support rods on the screen jacket create channels, which direct incoming
