It plays a vital role in various engineering applications, and analyzing the torque of seamless steel pipes requires a comprehensive understanding of several factors, including the material, manufacturing process, and intended use of the pipe.

SA106B American standard seamless steel pipe is a critical industrial material widely utilized across various industries, including petroleum, chemical, power, and shipbuilding. Renowned for its exceptional pressure resistance and high-temperature performance, it is an essential component in numerous engineering applications. This article will briefly introduce SA106B American standard seamless steel pipe.

Seamless carbon steel pipes are widely used in industries such as petroleum, chemicals, electricity, and metallurgy due to their excellent properties, including high-temperature resistance, corrosion resistance, and pressure endurance. These pipes are essential components in pipeline systems, offering strength and durability in various demanding environments. This article will briefly introduce common models of seamless carbon steel pipes.

Flange grade standards are essential in ensuring the proper function, safety, and reliability of flange connections in various industries. Understanding these standards is critical for selecting the right flange for a specific application, based on factors such as pressure, temperature, and the type of media being transported.

Flange design involves creating a connection system for flanged joints, which includes three key components: gasket design, bolt (or stud) design, and the flange body design. The most widely used method for flange design is the Waters method, which is adopted in GB 150. Below are the main points involved in this design approach.

Plastic-coated steel pipes are commonly used in various applications due to their corrosion resistance and durability. However, to ensure their performance, proper connection methods are crucial. Here are some of the common techniques for connecting plastic-coated steel pipes.

Seamless pipes fall under Chapter 73 of the HS Code system, titled “Articles of Iron and Steel.” Specifically, they are categorized under heading 7304, which pertains to "Seamless iron (other than cast iron) or steel pipes, tubes, and hollow sections." This heading is further divided into subheadings based on characteristics such as diameter, thickness, and material composition. This article will briefly introduce HS codes 7304 for import and export of seamless pipes.

Cold Drawn Seamless Tubes (CDS) are widely utilized in applications that demand exceptional strength and resistance to high pressure. In comparison to hot-finished seamless tubes, CDS offers tighter tolerances and superior mechanical properties, making them ideal for mechanical use. These tubes are particularly favored in the hydraulic industry for manufacturing chrome-plated telescopic cylinders and hydraulic rods. Additionally, they are commonly employed in the production of large-diameter, thick-walled, high-pressure hydraulic cylinders. Cold drawn seamless tubes are also integral to the manufacturing of heavy-duty equipment, including cranes and garbage trucks. Below is a detailed size chart for cold drawn seamless tubes.

Galvanized steel pipes are steel pipes coated with a layer of zinc, which serves as a protective barrier against corrosion, significantly extending their service life. This zinc layer acts as a solid "protective armor" for the steel pipe, safeguarding it from the damaging effects of environmental erosion. This article will briefly introduce application of galvanized steel pipes in power engineering.

The petrochemical industry is a vital pillar of the national economy, involving complex production processes that often operate under harsh and extreme conditions. Throughout the oil refining and chemical product synthesis stages, the pipeline system must endure high temperatures, high pressures, and severe corrosive environments. This article will briefly introduce seamless steel pipes in the petrochemical industry.

In recent years, with the continuous improvement of welding processes for large diameter spiral steel pipes (SSAW), their processing quality and performance have significantly improved. As the variety of such pipes increases, there is now a noticeable gap in the quality of these pipes available on the market. So, what factors determine the quality of large diameter spiral steel pipes?

Domestic manufacturers of LSAW (Longitudinal Submerged Arc Welded) pipes often enhance the material's properties by adding alloys. After the cold drawing process, stress annealing is essential to eliminate residual stresses in the material, which helps prevent fractures in the LSAW pipes. This article will briefly introduce breakage prevention methods of straight seam welded pipe.
