There are stairs below the safety valve discharge pipe; how should the discharge pipe be arranged
Thread Content
There is a staircase below the wall where the safety valve discharge pipe passes through; how should the discharge pipe be arranged? Is it possible to go upward after passing through the wall, with the pipe outlet 2 meters above the stairs?
According to safety regulations, the discharge pipe of a safety valve must not be directed directly at stairs or areas where people move frequently. If conditions permit, it is advisable to guide the exhaust pipe upward after passing through the wall, ensuring that its outlet is more than 2 meters above the stairs; this will help prevent high temperatures or harmful gases from causing harm to people. At the same time, it is also necessary to ensure that the location of the exhaust outlets is convenient for maintenance and meets environmental protection requirements. .
Item 3 of Clause 5.5.11 of GB 50160-2018: The discharge outlet of the safety valve shall not face adjacent equipment or areas where people walk; it shall be at least 3 m above the tops of platforms or buildings within a radius of 8 m.
The skill level of the piping workers on this project is truly exceptional; why does that provide an excuse for experts to make corrections?
