Casing pup joints are essential components in the construction and operation of oil and gas wells. They allow for precise adjustment of the casing string length, ensuring proper placement of downhole equipment and alignment with wellhead components. Selecting the appropriate pup joints based on diameter, material grade, and thread type is crucial for maintaining well integrity, safety, and efficient operation.
Couplings are short lengths of pipe used to connect 2 joints of tubing or casing. They come with painted colour codes on their external surface to indicate their grades. Couplings are manufactured according to API 5CT and 5B specifications.
Drill pipe is a steel pipe with thread at the end, which is used to connect the surface equipment of the drilling rig to the drilling and grinding equipment or the bottom hole equipment at the bottom of the drilling. Drill pipe can be divided into three categories: kelly, drill pipe and heavy drill pipe. Drill collar is located at the bottom of the drill string and is the main component of the lower drill tool assembly. Its main feature is that the wall thickness is larger, and it has greater gravity and rigidity. In order to facilitate tripping work, elevator grooves and slip grooves can be processed on the outer surface of the inner thread of the drill collar. Drill collars are generally divided into three types: spiral drill collars, non-magnetic drill collars, and integral drill collars.
Slotted pipe are used for oil and gas wells. Steel casing pipes and tubing are applied to furnishing and installing cased tunnels, where they indicate to pass other utilities or obstructions without open excavation. Steel casing pipes and tube have smooth wall and a minimum yield strength of 35,000 psi. Corrosion-proofing water-based paint is applied on the outside pipe surface to protect against atmospheric corrosion during transportation and storage.
Petroleum special pipes are mainly used for drilling oil and gas wells and oil and gas transportation. Oil casing is mainly used to support the wellbore during driling and after completion to ensure the normal operation of the wholewell, Oil casing is the lifeline to maintain oil well operation. Because of the different aeolodical conditions.the stress state of underground is complex, and the comprehensive action of tension, compression, bending and torsion stresses acts on the pipe body, which puts forward higher requirements for the quality of casing itself.
API 5CT Q125 oil well casing pipe and tubing is a type of steel pipe with special threads that are used in petroleum well drilling. The API 5CT Q125 oil well casing pipe and tubing is mainly used to protect the well wall from damage in order to ensure the normal operation of the well. The API 5CT Q125 oil well casing pipe and tubing are made of high-quality steel pipes. There are two types of API 5CT Q125 oil well casing pipes: casing pipes and tubing pipes
P110 API casing or tubing is a relatively common one in Oil drilling. Because of the low steel grade of P110, it is used for shallow oil and gas extraction. Due to its low price among other grades of steel, it enjoys broader applications. P110 API casing or tubing is widely used in the extraction of natural gas and coalbed methane, and can be commonly found in shallow wells, geothermal wells, and water wells.

A casing pipe is a hollow steel tube that is typically rammed into place through the earth by using a hydraulic or pneumatic jack. After being driven, the displaced soil is removed and the product pipe, or carrier pipe, is inserted inside the steel tube. Available Sizes Category:ERW, HFW or SMLS Standards:API 5CT PSL1/PSL2 J55,K55,N80-1,N80-Q,API 5CT PSL1/PSL2 L80-1, L80-9Cr,L80-13Cr,C90, C95, P110, Q125 Steel Grade:H40, J55, K55, N80
Tubing and casing pup joints are crucial components in the oil and gas industry for adjusting the length of tubular strings to precise measurements required for specific downhole operations. They are manufactured to meet stringent API 5CT standards, ensuring reliability and performance in various operational conditions. The seamless construction, rigorous testing, and quality finishing processes ensure these pup joints meet high industry standards for safety and efficiency.

Through rigorous manufacturing processes, precise dimensions and tolerances, and comprehensive testing, H40 casing pipes deliver dependable performance in various drilling and production environments.
The American Petroleum Institute specification API 5CT J55 Pipe is designed for use in the oil and gas industry. API 5CT J55 is a commonly used petroleum casing pipe material. It is produced according to the API 5CT standard and used in a variety of well types, both oil and natural gas. The main purposes of using casing or tubing are to protect the wellbore from collapse and to provide a conduit for well fluids. The casing is placed in the well first, followed by tubing, which is often smaller in diameter and thus can be nested inside the casing. Both casing and tubing must be made from strong materials that can withstand the high pressures and temperatures encountered deep underground. API 5CT J55 meets these requirements and is, therefore, an excellent choice for OCTG (oil country tubular goods) applications. It is typically produced as seamless steel pipe, but can also be procured in welded form. API 5CT J55 has a relatively high yield strength and good fatigue resistance, making it an ideal choice for high-pressure, high-load applications such as petroleum products.
API 5CT K55 is a pipe grade specified by the American Petroleum Institute. API 5CT K55 is a type of well casing that is typically used in well drilling operations. The casing and tubing are OCTG (oil country tubular goods) that are used to form the walls of the well. The steel pipe is placed in the well and held in place by cement. The cement helps to protect the well from collapse and keeps the well fluids from escaping. API 5CT K55 is a popular choice for well drilling because it is durable and can withstand high temperatures and pressures.
