When should the tensile strength of a pipe be considered for installation?

The tensile strength of a pipe should be primarily considered when it is under pressure. This is because pipes are typically subjected to various pressures during operation, whether it be from the fluids they carry or from internal stresses caused by the application of forces. Understanding the tensile strength is crucial to ensure that the pipe can withstand the pressure without rupturing or failing. Tensile strength reflects the maximum amount of tensile (stretching) stress that a material can withstand before failure, making it a critical factor in maintaining the integrity and safety of piping systems during use.

While other factors such as high temperatures and conditions during transportation or preparation (like painting) can influence a pipe's performance, the most critical time to consider tensile strength is when the pipe is in service and subjected to internal pressures. This ensures that the installation will be safe and effective under the expected operational conditions.
