How common is the practise of drilling holes in pump check valves?

If a high pressure system with high flow is discharging into atmosphere through a 2" gate valve and a small length of pipe .

I am making a fast budget, does ab?ny one know the aproximate price of a 60 hp, 300 psi, 430 cfm API pump

What be the best mitigation process if a tank in service with an external floating roof and has a leak on the double deck pontoon?

Now serving as an engineer in training (EIT). I'm using API 650, AISC Steel Const Manual, ASCE 7

My vendor is offering the Body Gas test as per API 6A PSL 3G in which the method to detect the leak is by sniffing probes over the areas of leakage suspected.

When a gate valve is newly manufactured I can understand why it needs a full pressure test to ensure the integrity of the casting or forging and to proove the pressure containment ability.

Building a system which involves an increase in internal pressure via an air tank in order to extend a series of telescoping tubes, and a subsequent full release of pressure back to atmosphere.
