Subject: [MW:1479] CHLORINE INSTITUTE PAMPHLET 6 CLASS II - Requirement

Dear All,

I have one piping class in LTCS material which is to be used for
CHLORINE GAS service.
With Design condition as follows:
Min 1.84 MPag@ -39 degC
Max 1.38 MPag@ 200 degC
Rating : 150#

For this class our Licensor along with code ASME B31.3 has given
requirement of CHLORINE INSTITUTE PAMPHLET 6 CLASS II.
Dear members can you explain me what exactly is this requirement, and if
its applicable only for valves or also for other fittings.
Thank You & Kind Regards
Vijay Kadam
