ASME STAMP: W-L&S-L

ASME STAMP: W-L&S-L

ASME STAMP: W-L&S-L

(OP)
We have a liquid chlorine-water heat exchanger. The manufacureres stamp on the ouside of this small HX has letters W-L and underneath that it has S-L. ASME designation for W-L is Welded-Lethal service. Any idea what S-L represents. Thanks.

RE: ASME STAMP: W-L&S-L

The "S" is ASME for Section I manufacture and assembly in house or in the field.  "L" may have a dual meaning as I've seen "L" meaning lined especially on water heaters.

Thank you uncle syd. i was off ill for a few days but am better now.
Should not "S" be inside a clover type template. In our case it is merely amongst other letters. I would appreciate your comments.

RE: ASME STAMP: W-L&S-L

If the is an ASME symbol it should be in square with rounded corners. I would check with the manufacturer to determine the meaning of the stamps as they don't appear to properly applied if they are ASME designator.
