In order to increase the popularity of the heat exchange forum, a \"Question of the Day\" activity has been introduced there; this helps to foster an active atmosphere for technical exchanges while also providing members with certain financial rewards. 【Daily Question】True or False: When checking the pressure for the pressure test, for shell-and-tube heat exchangers where the shell side pressure is lower than the tube side pressure, it is not necessary to deduct a corrosion allowance. (Correct) Note: We will close this post after 24 hours to announce the ** and provide an explanation, as well as to reveal the best reply (the best assistance).
