API 5L X60
TUSPIPE’s API 5L X60 line pipe is API certified, offering higher strength and reliable performance. TUSPIPE utilizes high-standard production processes to provide customers with high-performance pipes suitable for medium- and high-pressure transmission environments.
API 5L X60
API 5L X60 is a commonly used steel grade for line pipe manufacture. Its usage is prevalent in the petroleum and oil & gas industries, as these industries require transport pipes to convey petroleum and natural gases from their respective production facilities to suppliers. API 5L X60 line pipe is a high-strength, high-yield pipe that is produced to a set of international standards. API 5L X60 pipelines are also available in PSL-1, PSL-2, onshore/offshore, and sour service configurations.
The American Petroleum Institute, or API, is the largest trade association for the oil and gas industry. Every year, they publish hundreds of standards that govern everything from the quality of petroleum products to the safety of offshore drilling rigs. One of their most important standards is API 5L, which covers line pipes used in pipelines for transporting oil, natural gas, and water. The API 5L specification includes strict requirements for material composition, diameter, wall thickness, and tensile strength. As a result, API 5L line pipes are some of the strongest and most durable pipes on the market. They are also highly resistant to corrosion and can be used in a wide range of environments. Whether transporting crude oil from an offshore rig or natural gas to a power plant, API 5L line pipes are up to the task.

Dimensions and Sizes of API 5L X60 Line Pipe
API 5L X60 come in a range of diameters, sizes, and dimensions. The diameter of the pipe generally ranges from 2 inches to 60 inches. The pipe size is based on its inside diameter (ID) and outside diameter (OD). The ID of the pipe must meet the specified standards to be compatible with the fittings that will be used. The OD of the tube must also meet certain standards for it to be correctly sized for transportation and installation. The wall thickness of each size pipe is specified in ISO 4200 and ASME B36.10M.
