  • OCTG TUBING


    OCTG API 5CT Pipes – are used in oilfield industries. consisting of casing, tubing, drill pipe, conductor pipe, couplings, & pup joints. Most of them are Seamless Steel Pipes. Tubing, is used within the casing to convey the oil or gas to the ground surface, Tubing sizes from 1.050 to 4.5 inches O.D. inclusive, wall thickness from 3.18 mm to 10.54 mm.

  • OCTG CASING


    OCTG API 5CT Pipes – are used in oilfield industries. consisting of casing, tubing, drill pipe, conductor pipe, couplings, & pup joints. Most of them are Seamless Steel Pipes. Casing is the structural retainer for the walls of oil and gas wells, Casing size ranges from 4.5 to 20 inches O.D. inclusive, wall thickness from 5.21 mm to 15.88 mm.

  • TUBING & CASING COUPLING


    A range of fuel couplings includes: API dry disconnect couplings, API vapour recovery couplings and gravity drop couplings). They are common to the loading and unloading operations of fuel road tankers. ... API couplings are made of aluminium.

  • OCTG LINE PIPE


    OCTG Line Pipe is a high strength carbon steel pipe used for transporting crude oil, petroleum products, natural gas and water. It is a pipeline which carries only one type of fuel. These pipes are made as per metallurgical specifications developed by API (American Petroleum Institute). Line pipes are manufactured in a wide range of pipeline diameter size ranging from 2 inches to 48 inches.

  • OCTG DRILL PIPE


    API 5D OCTG Drill Pipe are seamless steel pipes used to drill oil well by transmitting power to a rotary drilling tool from the surface to below ground level, the drill pipes cover sizes form 2 3/8 to 6 5/8 inches O.D. inclusive, wall thickness from 6.88 mm to 12.7 mm.

  • OCTG PUP JOINT


    OCTG PUP JOINT: A pup joint is a pipe of non-standard length used to adjust the length of tubular strings to its exact requirement.

  • DRILL COLLAR


    OCTG Drill collars are extra-heavy integral tools used to concentrate weight onto the drill bit so as to produce sufficient force for the drill bit to break rock efficiently while drilling. They are made of AISI 4145H modified steel and are connected between drill pipes and drill bits.
