インフラストラクチャー

Due to their high strength and seismic resistance, steel tubes are commonly used for columns, beams, pillars, and other parts of building structures such as tunnels, airports, bridges, and platforms. Steel pipes can withstand enormous loads and are indispensable for buildings with large spans and spaces.

オイルとガス

Line pipe, oil tubing, casing pipe, and drill pipe are critical materials in the onshore and offshore oil and gas extraction and transportation industries due to their high strength, high collapse resistance, and resistance to low temperature, high pressure, corrosion, and cold.

化学処理

Steel pipes are resistant to corrosion, high temperatures, and high pressures, so they are used to transport a variety of chemical media, such as acids, alkalis, and salts. Steel tubes are also commonly used to manufacture equipment such as boilers, heat exchangers, condensers, reactors, and distillation towers in refineries and chemical plants.

発電

Steel tubes are widely used as power and process tubes in thermal power plants, including high-pressure boiler tubes, supercritical or ultra-supercritical high-pressure boiler tubes, air preheater tubes, superheater tubes, economizer tubes, and tubes for onshore and offshore wind turbine blade support structures.

Automotive and Machinery

Steel tubes are widely used for their high strength and safety in the manufacture of automobile half shaft sleeves and drive axle housing axle tubes, crane boom tubes, hydraulic cylinders, cylinders and pistons, hydraulic support tubes, pump bodies and accessories, rollers, conveyor rollers, rolling bearing inner and outer sleeves, high-pressure vessels, and so on.

水処理

Steel pipes are used in piping systems for water and sewage treatment plants and waste incineration plants, as well as in the manufacture of structural components for environmental protection equipment such as desulfurization towers and dust collectors.

造船

Steel pipes are used in ship hull structures, oil and gas transportation piping for tankers, and engine cooling systems. They are also corrosion-resistant.

海洋工学

Steel pipes are used for struts, beams, buoys, and other components of offshore drilling rigs and engineering equipment structures.

Industrial Gas Storage

High-strength seamless steel pipes can withstand high pressure and are widely used for storing industrial gases such as hydrogen, oxygen, chlorine, nitrogen, helium, acetylene, methane, propane, and liquefied natural gas.

Defense Industry

Seamless steel tubes are characterized by high strength, creep resistance, high-temperature resistance, impact resistance, and fatigue resistance. They are widely used for ordnance missiles and bomb shells, rockets, gun tubes, tank and missile destroyer gun tubes, and land-based missile launch tubes.
