All About API X46 Carbon Steel Line Pipe

What is API X46 Carbon Steel Line Pipe

Oil and gas transportation uses high yield carbon steel line pipe, which is specified by API X46. The American Petroleum Institute (API) is the organization that establishes guidelines for the manufacture and application of products and equipment for the oil and gas industry. The code “X46” denotes the steel’s minimum yield strength, which is 46,000 pounds per square inch (psi).

For the transportation of oil and gas in pipelines, carbon steel line pipes are frequently employed. These pipes are constructed of a carbon steel alloy with trace amounts of nickel, chromium, and molybdenum. Because of this, they are affordable and simple to produce. It is a common choice for use in pipelines for the transmission of oil and gas because API X46 Carbon Steel Line Pipe has outstanding mechanical characteristics and can bear high pressure. It can be molded and constructed with ease and has good weldability. Its great resistance to corrosion and erosion also makes it widely employed in severe situations.

API X46 Carbon Steel Line Pipe Specification

Material: Carbon, manganese, phosphorus, Sulphur, and silicon are the main ingredients in API X46, a high yield carbon steel pipe. Depending on the manufacturer and the production method, the precise composition may change.

Size Range: The API X46 line pipe’s size range normally falls between 2 and 48 inches in outside diameter, though this might vary depending on the manufacturer.

Yield Strength: The API X46 line pipe has a minimum yield strength of 46,000 psi, or 315 MPa.

Tensile Strength: The API X46 Carbon Steel Line Pipe has a minimum tensile strength of 63,000 psi, or 434 MPa.

Elongation: For longitudinal specimens of API X46 line pipe, the minimum elongation is 22%, and for transverse specimens, it is 14%.

Impact Qualities: A minimum average Charpy V-notch impact energy of 41 Joules (30 ft-lbf) at a temperature of -10°C (-14°F) is used to test the impact qualities of API X46 line pipe.

Chemical composition: API X46 line pipe must adhere to the standards outlined in the API 5L standard with regard to chemical composition. The maximum levels of silicon, manganese, phosphorus, sulphur, and other elements are also stated, with the maximum carbon content being 0.28%.

Testing: To make sure API X46 line pipe satisfies the necessary criteria, it must go through a number of testing methods, including hydrostatic testing, ultrasonic testing, and magnetic particle inspection.
