Structural steel tubes are indispensable components in modern construction, manufacturing, and infrastructure projects. Among these, welded structural tubes—including square steel tubes, ERW steel tubes, and specialized products like greenhouse tubes—are widely used due to their versatility, strength, and cost-effectiveness. This article explores their materials, international
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,
Fire fighting tubes are critical components of fire protection systems, designed to deliver water or fire-suppressing agents efficiently during emergencies. These tubes must meet stringent quality, durability, and safety standards to ensure reliable performance under high-pressure conditions. In this guide, we explore the materials, steel
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.
I. Materials and steel grades of seamless steel pipes and welded steel pipes Seamless steel pipes and welded steel pipes use different materials and steel grades according to their uses and requirements. Common ones include: 1. Seamless steel pipes Seamless steel pipes are usually used
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
Carbon steel pipe elbows are connectors used to change the direction of pipeline fluids and are commonly found in pipeline systems in industries such as petroleum, natural gas, chemical, and electric power. Elbows are classified into three basic types: 45°, 90°, and 180°. Special angles
Spiral welded pipe is a common type of steel pipe, and spiral welding technology is used in its manufacturing process. Spiral welded pipe has good strength and pressure resistance due to its unique structural characteristics and manufacturing process, and is widely used in fields such
High-pressure boiler tubes are key components used in boiler systems and are subject to high-temperature and high-pressure working environments, so their performance requirements are extremely strict. Among the many types of boiler tubes, seamless steel tubes are widely used in the manufacture of high-pressure boiler
Oil and gas line pipes are steel pipes specially used for transporting fluids such as oil and natural gas. As a key component for oil and gas transportation, it not only needs to withstand high pressure, corrosion, and low temperature, but also must meet the
