API 5L X52 Specification Of Welded Pipe

Name: API 5L X52 Specification Of Welded Pipe
Brand: GNEE
SKU: 255137147

API 5L X52 pipes, which are specified by the American Petroleum Institute, are available in two types: seamless and welded. They play a key role in the field of oil and gas transportation, and are used to transport gas, water and oil products. Their sizes can be flexibly adjusted according to the manufacturer's capabilities to meet various engineering requirements.

Product Introduction

API 5L X52 pipes, grade "X52" corresponds to excellent mechanical properties, with a minimum yield strength of 52000 PSI (about 360 Mpa) and a minimum ultimate tensile strength of 66000 PSI (about 460 Mpa). They are also called L360 pipes. They are medium-grade in the API 5L and ISO 3183 specifications and are capable of long-distance, high-pressure transportation of oil and gas.
The API 5L X52 specification followed by this pipe is closely aligned with ISO 3183 of the International Organization for Standardization. ISO 3183 sets standards for industry pipeline transportation. The developers divide the two product specification levels into PSL 1 and PSL 2. PSL 1 guarantees the basic performance of conventional transportation, while PSL 2 adds chemical, mechanical properties and testing requirements to cope with complex working conditions.
In terms of manufacturing process, X52 welded steel pipes use welding processes such as electric resistance welding (ERW), straight seam submerged arc welding (LSaw), and spiral submerged arc welding (SSaw). Among them, electric resistance welding (ERW) is suitable for manufacturing welded pipes with a smaller outer diameter (up to 24 inches in outer diameter), straight seam submerged arc welding (LSaw) can manufacture welded pipes with an outer diameter of up to 56 inches, and spiral submerged arc welding (SSaw) can be used to manufacture large welded pipes with an outer diameter of up to 100 inches. With the help of various processes, the quality of the pipes is guaranteed to be excellent and the performance meets the standards. At the same time, it can be flexibly selected according to the actual situation of the project site.
API 5L X52 high-pressure pipes are designed for high-pressure and high-temperature oil and gas transportation, focusing on toughness and impact resistance, and can cope with harsh environments such as acid. However, high sulfur in acid wells can easily cause stress corrosion. Manufacturers often use anti-corrosion measures to apply oil, varnish or black paint on the surface of the pipe to enhance corrosion resistance, extend service life in harsh environments, and ensure reliable transportation.
