Technical Overview of the ASME B36.10M Standard
The ANSI/ASME B36.10M standard is a fundamental regulatory document governing the geometric parameters of welded and seamless steel pipes designed for operation in high-pressure systems, the oil and gas industry, and power engineering. Specialists at EV Group China emphasize that this standard defines not only nominal diameters and wall thicknesses (schedule classes) but also requirements for the weight characteristics per linear meter of the product.
Unlike metric standards, ASME B36.10M operates using the Nominal Pipe Size (NPS) and the schedule index (Schedule), which is critical when designing piping systems while taking into account operating temperatures and medium pressure.
Main Characteristics and Classification
The Schedule classification system (e.g., Sch 40, Sch 80, Sch 160) allows EV Group China engineers to select the optimal pipe wall thickness depending on operating conditions. The standard covers pipes made of carbon, alloy, and stainless steels, ensuring size unification for compatibility with fittings and flanges of the corresponding series.
| NPS (inches) | Outside Diameter (mm) | Typical Schedule Values |
|---|---|---|
| 1/8 | 10.3 | Sch 40, Sch 80 |
| 1 | 33.4 | Sch 40, Sch 80, Sch 160 |
| 2 | 60.3 | Sch 40, Sch 80, Sch 160 |
| 4 | 114.3 | Sch 40, Sch 80, Sch 120 |
EV Group China supplies pipe products that fully comply with the requirements of ASME B36.10M. Our products undergo strict geometry control and non-destructive testing methods, which ensures the reliability of pipelines under extreme loads.
