1. The closed high-pressure safety valve with full spring opening must be installed vertically and directly on the joint of the container or pipeline. The inside diameter of the joint shall not be less than the inlet diameter of the safety valve.
2. The outlet of the safety valve must be equipped with appropriate expansion joints to prevent thermal expansion of the discharge pipe from bringing undue thermal stress to the safety valve. The inner diameter of the discharge pipe should be larger than the diameter of the valve outlet, and the length should be as short as possible to avoid turning. Discharge pipe and expansion joint weight should not be applied to the safety valve, should be fixed to the building. The distance between the center line of the discharge pipe and the center line of the valve body is as short as possible. Each safety valve shall be individually piped.
3. The outlet of the silencer shall have sufficient area to prevent back pressure from affecting the discharge capacity of the valve.
