Hi all,

Regarding support for PSV inlet & outlet, which is the better method as below:

Method 1:
Use trunnion (single/double) with a tight U-band for both inlet and outlet lines. Trunnion are on platform. Sometime, outlet is tight and inlet is slide, or they can be exchanged if necessary.

Method 2:
Use single trunnion with hold down guide for both inlet and outlet lines. Trunnion are on platform. And use a stopper directly after PSV outlet (no resting).

Normally, I use Method 1 to support PSV, there is no problem with reaction force in the calculation and the company guarantee vibration effect is negligible.

However, I wonder why some other companies are applying Method 2.

Regards,
