1. Customers may describe number of section, attachment, shape, material of filler, material of jacket and heat exchanger shapes by symbol mark as mentioned in.
2. Standard nominal thickness in 3.2mm and pitch size of corrugation is 3, 4, 5, 6.5mm
1. Gasket minimum In-dia is 13mm.
2. Related standard is ASME B16.5 & JIS B2238/2239.
Shapes – Heat Exchanger gasket have complicated partition bar(s).
The typical shapes of the gasket are as illustrated below.
Dimensions.
Gasket outside diameter, inside diamenter and thickness are enough to design and manufacture round shape gasket without partition(s). However, the shapes and detailed dimensions of portion of partition bar must be furnished if the gasket is applied in multi-pass heat exchangers. The following dimensional list may be filled in ordering for correct fabrication.
“Dimensional list of heat Exchanger.”
1. Thickness tolerance equals +0.79㎜, －0.
2. Tolerances for gaskets of nominal size 1/2″inch through 24 inches : OD tolerance equals +1.59㎜, －0 : ID tolerance equals +1.59㎜, －0.
3. There are no 400－pound flanges in size 1/2″inch to 3inchs(use 600 pound), nor 900 pound flanges in size 1/2″inch to 2 1/2inches(use 1500 pound). Also, there are no 2500 pound flanges larger than 12 inches.
4. Tolerances for gaskets of nominal size 26 inches through 60 inches : OD tolerance equals +3.175㎜, －0 : ODtolerance equals +3.175㎜, －0 : ID tolerance equals +3.175㎜, －0.
