What is the minimum thickness for steel pipe connectors for sizes over 10 inches?

The minimum thickness for steel pipe connectors for sizes over 10 inches is specified as Gauge 16. This standard is in place to ensure adequate strength and durability in the piping system, especially as the size of the pipe increases and potential stresses on the connectors also rise. Using a thicker material helps to prevent failures, leaks, or structural issues in high-pressure or high-load applications that are often associated with larger pipes.

The other gauges listed—22, 24, and 26—are thinner materials and would not provide the necessary strength and integrity required for larger pipe sizes. Therefore, they do not meet the industry's safety and performance standards for steel pipe connectors in these applications. In summary, Gauge 16 ensures that the connectors can withstand the operational demands that come with larger diameter pipes, making it the appropriate choice for this requirement.
