: Guidelines for handling "stress raisers" like keyways, shoulders, and splines.
This standard covers the requirements for the design, materials, fabrication, testing, and inspection of pipeline transportation systems for liquids and gases. It includes guidelines for:

The core of the standard's technical approach provides a modern, fatigue-based alternative to older, static-yield-based methods. Its methodology is built on several key pillars: Asme B106.1m Pdf
The main formula presented in the ASME B106.1M standard for determining the shaft diameter (d) usually looks like this:
Although officially withdrawn by ASME in 1994, the methodology remains the industry benchmark. Organizations like the Conveyor Equipment Manufacturers Association (CEMA) explicitly endorse and incorporate its formulas, validating its calculations as technically sound for modern fatigue analysis.

By following the optimized design procedures in B106.1M, engineers avoid "over-engineering." A shaft that is 10% thinner than a guess-based design saves material, machining time, and weight—leading to significant cost savings in mass production.

ASME B106.1M is a standard that covers the requirements for piping and pipelines in various industries, including oil and gas, chemical processing, and power generation. The standard provides guidelines for the design, fabrication, installation, and testing of piping systems, including materials, fittings, and valves. Its methodology is built on several key pillars:
The ASME B106.1M standard was officially withdrawn by ASME without a direct replacement .
The maintenance report cites: "Per ASME B106.1m, Clause 4.2, vibration severity is elevated to Zone C. Plan corrective balancing within 30 days."
