What is a steel casing?
A C steel ASING PIP ë or pipe used in drilling or any underground installation is called casing pipe or pipe. Steel casings, also known as boxed pipes, are most commonly used in underground construction to protect all types of utility lines from damage.
API Specification 5CT - Specification 5CT / ISO 11960, Specification for casing and tubing, 8th edition, oil and gas industry, steel pipe used as casing or tubing for wells.
The casing tube is used for casing oil and gas wells. The large diameter tube in the casing is assembled and inserted into the bore portion of the bore.
Our company has achieved widespread recognition in offering MS Casing Pipes to the clients. MS Casing Pipes are extensively used in various industries such as chemical, water treatment, food and beverage to transfer different types of fluids. Offered range is widely acclaimed in the market for optimum quality and high strength. These products are tested on well-defined parameters in order to remove all the flaws.
Steel Casing Pipe, also known as encasement pipe, is most commonly used in underground construction to protect utility lines of various types from getting damaged. Such damage might occur due to the elements of nature or human activity.
Quality control
All welds must be performed by a qualified welding operator in accordance with ANSI / AWS D1.1. Complete a reduced partial tensile specimen of 1000 feet per lot and wall thickness per batch. It is confirmed that the tensile strength is not less than 95% of the grade for the use of steel, when the minimum strength is specified by the customer. No hydrostatic test is required. Check all connections to make sure they are free and harmful at the factory. Otherwise, reject and repair the part before shipping.

Casing characteristics
The casing is important for oil drilling equipment, and its main equipment includes drills, core tubes and casings, drill collars and drilled small diameter steel pipes.
The casing is used to support the oil and gas walls of the pipe to ensure drilling and completion during normal operation of the well. Depending on the depth and geological conditions of each hole in the borehole, several layers of the outer casing are used. After cementing it and using it with the tubing, the drill pipe is different and cannot be reused, consuming material at one time. Therefore, the total consumption of the casing is 70% of the oil well pipe. Conduit, surface casing, casing and production casing: The casing can be divided according to the application. The casing is a large diameter pipe that acts to anchor oil and gas wells or wellbore walls. The casing is inserted into the wellbore and cement is fixed to prevent the wellbore at the formation and wellbore from collapsing and to ensure circulation of the drilling mud to the mining drilling.
