Products Introduction:
Seamless steel pipes are widely used in various industries and applications due to their high strength, durability, and ability to withstand high pressure and temperature. The following are the standards, classifications and uses of seamless steel pipes: standard: Seamless steel pipes are manufactured in compliance with specific standards set by organizations such as the American Society for Testing and Materials (ASTM), the American Petroleum Institute (API), the International Organization for Standardization (ISO) and national standards bodies of different countries. Common seamless steel pipe standards include ASTM A106 for high temperature applications, ASTM A53 for general use, API 5L for oil and gas transportation, and DIN 2391 for precision applications.
Classification: Seamless steel pipes can be classified according to different standards: Manufacturing method: Seamless pipes are produced by hot rolling, cold drawing or cold drawing processes. The difference from welded pipes is that there are no welds. Sizes and Dimensions: Seamless steel pipe is available in a variety of sizes and dimensions, including standard pipe specifications (e.g., SCH 40, SCH 80) as well as specific outside diameters and wall thicknesses. Material grade: Seamless steel pipes are classified according to material composition, including carbon steel, alloy steel, stainless steel and other special steels.

| Out Diameter(mm) | Wall Thickness (mm) | Length (m) | Standards |
| 22~325 | 1.73～40 | Random Length, Fixed Length, SRL, DRL | ASTM A106/A53, ASTM A519, JIS G 3441, JIS G3444, JIS G3445 DIN 2391, EN10305, EN10210, ASME SA106, SA192, SA210, SA213, SA335, DIN17175, ASTM A179 |
Applications: Seamless steel pipes are widely used in various industries due to their excellent performance characteristics:
1) Oil and Gas Industry: Seamless steel pipes are widely used on land and sea to transport crude oil, natural gas and petroleum products, as well as in exploration, production and refining operations.
2) Power generation: Seamless steel pipes are used for high-pressure steam and water transportation in power plants, including boilers, super heaters and heat exchangers.
3) Mechanical and Structural Applications: Seamless steel pipes are used in mechanical engineering, structural construction and machine manufacturing where high strength and precision are required.
4) Automotive and Aerospace: Seamless steel pipes are used in automotive manufacturing, aircraft and aerospace applications, and other transportation-related industries for their strength and reliability.
5) Industrial Processing: Seamless steel pipe is used in a variety of industrial processes, including manufacturing equipment, machinery and components that require resistance to high temperatures and pressures. Seamless steel pipe is chosen for applications requiring high performance, corrosion resistance and reliability. They are favored for their uniform structure, consistent quality, and suitability for critical operations across different industries. When selecting seamless steel pipe, it is important to verify that it meets the specific standards, material specifications and performance requirements of the intended application.
