The steam main pipe branches off to each tower (which are considered pressure vessels). The steam main pipe already has a safety valve. Is it still necessary to install a safety valve on each tower?

Depending on the operating conditions of the gas-using equipment, pressure regulators or safety valves are required for low pressure!
It is necessary; safety valves are generally required for pressure vessels
This depends on the magnitude of the steam pressure and the equipment’s design pressure. If the equipment’s design pressure is higher than the set pressure of the steam safety valve, then having a safety valve on the main steam pipe should be sufficient. However, if the equipment’s design pressure is lower than the set pressure of the steam safety valve, then a safety valve must also be installed on the equipment itself.
Safety valves must be installed separately for tower equipment
Pressure vessels have their own design and manufacturing standards, which are unrelated to whether your system has safety valves or not
