What is the maximum pressure for transfer systems required to withstand during testing?

The maximum pressure for transfer systems during testing is set at 1.1 times the Maximum Allowable Working Pressure (MAWP). This is established to ensure the structural integrity and safety of the transfer systems while providing a margin of safety above the normal operational pressure. By testing at 1.1 times the MAWP, the system can demonstrate its ability to handle slight variations in pressure and any potential surges that may occur during operations. This standard is critical for ensuring that the equipment is reliable and safe for use in various marine applications, reducing the risk of failure during operation.

Choosing a testing pressure significantly higher than this, such as 1.5, 2 times the MAWP, or other higher multipliers, could lead to unnecessary stress on the system, increasing the potential for wear and premature failure. Thus, 1.1 times the MAWP is the appropriate standard for conducting safe and effective pressure testing.
