API 5L X65 specification

API is the abbreviation of American Petroleum Institute, 5 refers to the 5th committee, and L refers to line pipe. So the API 5L standard is the line pipe standard referred to by the Fifth Committee of the American Petroleum Institute. Its main contents are 1. It stipulates the grade, steel grade, and delivery status of API 5L standard steel pipes; 2. The purchase information materials that buyers need to submit; diameter and cold expansion, heat treatment, etc.; 4 acceptance limits, mainly including the chemical composition of the steel pipe, tensile properties, hydrostatic pressure test, bending test, flattening test, guided bending test, impact test, surface defects, dimensional deviation, etc.; 5. Inspection of steel pipes; 6. Marking, etc.

Specification

1.Craftsmanship Excellence

Our steel seamless pipes are crafted with meticulous attention to detail, ensuring each product meets the highest quality standards. Utilizing the latest in manufacturing technology, we employ a precise extrusion process that eliminates the need for welding, resulting in a pipe with uniform wall thickness and exceptional strength. The seamless design not only enhances the pipe's ability to withstand high pressures but also reduces the likelihood of leaks and failures, making it a reliable choice for critical applications.

2.Quality Assurance

Quality is at the core of our production philosophy. Each steel seamless pipe undergoes a series of stringent quality control checks at every stage of production. From the selection of raw materials to the final inspection, we adhere to international quality standards such as ISO, ASTM, and API. Our state-of-the-art testing facilities, including non-destructive testing (NDT) and mechanical testing, ensure that every pipe is free from defects and possesses the required mechanical properties.

3.Material Integrity

The material used in our seamless pipes is carefully selected to provide the best balance of strength, ductility, and corrosion resistance. We offer a wide range of steel grades, including carbon, alloy, and stainless steel, to cater to various industrial demands. The heat treatment process, such as quenching and tempering, is meticulously controlled to achieve the desired microstructure, enhancing the pipe's overall performance and extending its service life.

4.Precision Engineering

Precision engineering is a hallmark of our seamless pipe production. We employ computer-aided design (CAD) and computer-aided manufacturing (CAM) systems to ensure accuracy in dimensions and tolerances. Our seamless pipes are produced with a high degree of dimensional accuracy, which is essential for fitting and assembly in complex engineering projects. This commitment to precision engineering ensures that our customers receive products that are not only of superior quality but also perfectly suited to their specific application needs.
