Heat exchanger selection information for help
Thread Content
Ask for help regarding heat exchanger standards. At that time, the manufacturer's personnel came to the site with the standards, counted the number of bolts and measured the diameter, and compared the standards to know the size and model of the equipment. What is the standard for asking for help?
Regardless of whether they are right or wrong about which bolts they are counting, equipment bolts or connection bolts, you have to check whether the drawings and equipment are the same, and ask them to find the drawings and explain them. Generally, standard equipment flanges and connecting flanges such as NB/T47020-27 and HG/Y20615, 20592 are used. The drawings will have corresponding parts standards. If there is a problem, first check whether it is the same as the design drawings, and then check whether the standards are met.
What I took was a white paper on the standard category, and I figured it out after counting the bolts on the head. I remember it very clearly because the manufacturer made a mistake in our control and made 6.3 into 4.0. The pressure level is wrong and the tube sheet thickness is different.
I guess it is the heat exchanger type series. What kind of equipment is this? GBT 28712.1-2012 Heat exchanger type and basic parameters Part 1: Floating head heat exchanger GBT 28712.2-2012 Heat exchanger types and basic parameters Part 2: Fixed tube sheet heat exchanger GBT 28712.3-2012 Heat exchanger types and basic parameters Part 3: U-shaped tube heat exchanger
Um, pressure level, you are talking about the equipment flange. If the flange level is wrong, then the standard to look at is the equipment flange standard.

You're welcome, I mistook you for "cleaner", your name is awesome, hahaha
According to the comment, the flange pressure level is wrong. What he got should be the NB/T47020~47027-2012 pressure vessel flange, gasket, and fastener standards, which is what we usually call the equipment flange standard. Regarding the tube plate thickness, it may be due to the inconsistency in the tube plate thickness calculation caused by the change between the old and new standards. It depends on whether you require the tube plate thickness to be the same as the old equipment.
Yes, the correct answer on the 9th floor~~~I have done such a thing too~~~
