What is the process required for installing a steam temperature and pressure reducer? Are official drawings from a design institute required? Is it necessary to register with the relevant authorities?

A friend’s factory needs to be connected to the park’s high-pressure steam network, with a pressure of 3.6 Mpa. To connect to this network, a temperature and pressure reducing device is required; however, the drawings provided by the design institute specify only one such device. We now want to add another one. We would like to ask the experts in the field of pressure pipelines whether it is necessary for the design institute to provide additional drawings, and whether such an additional device needs to be registered with the relevant authorities Are there any simple ways to do it? Thank you
It is necessary; for pressure pipelines, the design institute must prepare the drawings, which must then be filed with the quality supervision bureau.
Is another reason the failure to meet the pressure reduction standards?
Yes, the superheat is a bit high; it needs to be reduced further
Can it not be achieved by adjusting the water inflow volume of the temperature-reducing pressure regulator?
The water flow has been set to its maximum. The outlet of the previous unit still produced superheated steam, with a high degree of superheat; therefore, another unit needs to be added to reduce this superheat level
