  • Casing

    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 well bore 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. Well Casing serves as well sidewall. Standards and Technical Conditions for Supply:API Spec 5CT ISO1...

  • Drill Pipe

    Drill Pipe

    Drill Pipe: Drill pipe includes pipe body and tool joints(box and pin) welded together, used to connect drilling rig surface equipment and bottom equipment or bottom hole equipment. Drill pipe can bear heavy internal and external pressure, and twist, bend and vibration which can be used more than one time during oil or gas production. Drill pipes are steel tubulars fitted with threaded ends called tool joints, which are commonly used in tension in the top part of the drill string to pump flui...

  • Pup Joint

    Pup Joint

    A pup joint is a casing or tubing of length shorter than Range 1 with the same thread connection, used to adjust the length of tubular strings to its exact requirement. Pup Joints are manufactured from AISI 4145H or 4140H-modified alloy, heat-treated to a Brinell Hardness range of 285-341 with a Charpy “V” notch minimum impact strength of 40 ft/lb at 70° F and one inch below the surface. Pup Joints are heat-treated to 110,000 PSI minimum yield. All connections are phosphate coated to impede g...

  • Slotted pipe

    Slotted pipe

    The slotted casing pipes using in oil exploration can prevent 99% sand, decrease 80% of oil well heavy maintenance, as well increase the strength of the oil well, integrality and stability of keeping sand off. Meanwhile, the laser incision tech can make the slot be smooth and precision. The structure of slotted casing pipe is sample, but it works highly efficient. Slotted tube processing is on high strength steel body with cold or hot working methods, cutting out hundreds of thousands of long...
