API 5CT /5B seamless Casing and tubing, K55, OD 4 1/2″ STC oil and gas pipeline

Tube for conveying gas, water, and oil in both and natural gas industries etc. Casing:Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore.It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi. Tubing: Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer […]

API 5DP drill pipes

API 5DP drill pipe, Grade E75, OD 127mm , wall thickness 12.7mm

Drill pipe is hollow, thick-walled piping that transfers drilling fluid and torque through the wellbore to the drill bit on a drilling rig. It is made to endure serious internal and external pressure, distortion, bending, and vibration as it both rotates and lifts the bottom hole assembly (BHA). Drill pipe is threaded on each end in a section of pipe described as the tool joint. It is manufactured, sampled, tested, and inspected in accordance with basic specs such as the American Petroleum Institute (API). Drill pipe Grade: E75, X95, G105, S135 . The wear-resistant belt of tool joint: Arnco 100XT, 200XT, 300XT, 400XT Internal coating drill pipe: TK34, DPC, TC2000, TC3000 Drill pipe Drill pipe API SPEC 5DP defines the technical delivery […]
