In the global energy infrastructure, pipeline systems play a vital role in transporting oil and gas efficiently and safely over long distances. At the heart of these systems lies the API 5L pipeline pipe, a product engineered to meet rigorous industry standards for durability, strength,

The global energy sector relies heavily on oil pipelines and gas pipelines to transport hydrocarbons safely and efficiently. At the heart of these systems lie seamless pipes and welded pipes, engineered to meet rigorous industry standards. This article explores the technical aspects of pipeline pipes,

In industrial pipeline systems, LSAW and SSAW are two mainstream types of welded steel pipes. Although both belong to the category of arc welded steel pipes, they have significant differences in manufacturing process, structural performance and engineering applications. 1. Essential differences in manufacturing processes 1.

There are several common surface treatment methods for steel pipes. The process, characteristics and uses of each treatment method are as follows: 1. Hot-dip galvanizing - Process: Immerse the steel pipe in molten zinc liquid to make the zinc adhere to the surface to form

Welded steel pipe weld seam style and characteristics According to the weld seam form and processing technology, welded steel pipe is mainly divided into straight seam welded pipe, spiral welded pipe and other special weld seam forms (such as girth welding, spot welding). Different weld

The caliber range of welded steel pipes is very wide. The specific caliber models vary according to different standards (such as national standard GB, American standard ASTM, European standard EN, etc.), but generally cover the following caliber classifications: 1. Nominal diameter (DN) Small diameter welded

The following lists the various materials commonly used for welded steel pipes, covering common international standards: 1. Carbon steel materials 1. Ordinary carbon structural steel: - Q195, Q215, Q235, Q255, Q275 (Chinese standard) - SS330, SS400, SS490, SS540 (Japanese standard JIS G3101) - ASTM A53

Welded pipe, also known as welded steel pipe, is a type of steel pipe that is formed by bending steel plates or steel strips into shapes and then connecting them into pipes through welding processes. It is a type of steel pipe widely used in

In the past month, China's steel industry has received a series of good news, especially in terms of rising billet prices, steady growth in steel pipe exports, and positive signs in future steel pipe price forecasts. 1. Billet price trend Since September, China's billet market
