Many of shell and tube type heat exchangers are equipped with expansion bellows on its shell body. Some of the bellows are equipped with locking collar arrangement and some without locking arrangement.

Is it necessary to lock the bellows while conducting shell side hydrotest of heat exchanger? Any standard API/ASME gives the reference about this?
