Supercritical fluid (SCF) pipelines are used in high-efficiency power plants, CO₂ sequestration, and aerospace propulsion, requiring seamless pipes with high-pressure endurance, corrosion resistance, and thermal stability.

Fusion reactors, such as ITER, use liquid metal or supercritical water cooling systems, requiring seamless pipes with extreme high-temperature resistance and radiation tolerance.

With the rise of the hydrogen economy, high-pressure hydrogen transportation pipelines have become a critical challenge. Seamless pipes, due to their absence of welds, uniform microstructure, and excellent crack resistance, are considered an ideal choice for hydrogen transport.

OCTG (Oil Country Tubular Goods) are specialized pipes used in the oil and gas industry to extract hydrocarbons from underground reservoirs. These pipes play a crucial role in ensuring the safety, integrity, and efficiency of oil and gas wells throughout their life cycle. Different types of OCTG are designed for specific applications and functions, depending on the conditions encountered during drilling and production.

The manufacturing process of OCTG involves several key steps to ensure the final product meets stringent industry standards. From raw material selection to final inspection, each stage plays a vital role in ensuring the strength, integrity, and reliability of the OCTG during oil extraction operations.

Oil casings are a critical component in the oil and gas industry, serving as protective barriers for wells during exploration and production. The materials used in the production of oil casings must meet stringent requirements to ensure strength, durability, and resistance to corrosion under harsh conditions. Common materials include carbon steel, alloy steel, and stainless steel, with each offering distinct advantages for different applications.

Geothermal energy plants use stainless steel piping for steam transport and reinjection wells, requiring resistance to extreme temperatures and aggressive geothermal fluids.

Aerospace applications require lightweight, high-strength stainless steel pipes for fuel lines, hydraulic systems, and exhaust components.

Ensuring the structural integrity of welded steel pipes is critical, especially for safety-critical applications like pressure vessels, oil rigs, and pipelines.

Hydrogen embrittlement (HE) is a severe issue affecting the integrity of welded pipes, particularly in oil & gas pipelines and hydrogen transport systems.

The microstructural evolution in the weld zone significantly affects the strength and toughness of welded pipes.

Residual stress is an important factor affecting the mechanical properties and service life of welded pipes. It arises due to non-uniform heating and cooling during the welding process.

Anti-corrosion steel pipe refers to a 3-layer structure polyolefin coated anti-corrosion steel pipe, which is a commonly used anti-corrosion pipeline in China. Let's take you to have a deeper understanding of anti-corrosion steel pipes. First, the anti-corrosion structure of anti-corrosion steel pipes and then the advantages of anti-corrosion steel pipes.

How does the thick-walled seamless steel pipe produce residual stress during cold drawing? The uneven deformation of the thick-walled seamless steel pipe under the additional stress cold drawing results in the residual stress after cold drawing.

Galvanized pipe is a galvanized pipe made by bending the strip steel or coil into a spiral shape and welding the inner and outer seams with double-sided submerged arc automatic welding. It is widely used in manufacturing industries such as construction, machinery, coal mining, chemical industry, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, etc. Let's take a look at the advantages and disadvantages of galvanized pipes.
