The design of application pressure for chemical pipelines is influenced by a combination of chemical properties, flow rate requirements, friction loss, material selection, and environmental conditions. By carefully considering these factors, engineers can ensure the safe and efficient transport of chemical substances, minimizing risks and maintaining the integrity of the pipeline.
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.

ERW BLACK Pipes. Electric Resistance Welded (ERW) Pipes are manufactured from Hot Rolled Coils / Slits. All the incoming coils are verified based on the test certificate received from steel mill for their chemistry and mechanical properties. ERW pipe is cold-formed into a cylindrical shape, not hot-formed.
Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length. In Seamless pipe, there are no welding or joints and is manufactured from solid round billets.

Seamless pipes are manufactured using a piercing process, where a solid billet is heated and pierced to form a hollow tube. Welded pipes, on the other hand, are formed by joining two edges of steel plates or coils using various welding techniques.
Carbon steel pipe is highly resistant to shock and vibration which making it ideal to transport water, oil & gas and other fluids under roadways.
