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

A steel tube and steel pipe seem like they might refer to the same thing to some folks, but in the oil and gas industry, we know better. In a nutshell, tubing is usually more of a structural element than pipe, which is, more often, used to transport liquids. With tubing, wall thickness (measured
API oil pipe specification and non-standard specification API oil pipe specification system API Standard is a general term for specification (SPEC), recommended practice (RP) and notification (BUL). "Specification" To facilitate communication between purchasers and manufacturers, to provide interchangeability between the same equipment and materials purchased from different manufacturers and produced at different times; and
What is the API standard for petroleum steel pipe? Petroleum steel pipe Petroleum pipe is the general name of oil-specific pipe (casing, oil pipe, drill pipe, square drill pipe, weighted drill pipe, drill collar, etc.) and pipeline pipe for oil and gas transmission, which runs through all aspects of oil drilling, well completion, oil
