Most applications for chlor-alkali and chlorate are at low pressures. The data provided for Flanged End Systems and Temperature/Pressure Correction Factors must be fully adhered to. We suggest that higher pressure applications be discussed with our field personnel  before proceeding.

NOTES:
** 1. No standard pressure rated fittings available for these sizes. Check with us for availability of custom fittings. 2. Pressure ratings  of threaded pipe must be derated 50% from the above table (e.g. 1" Sch 80 threaded connections rated at 50% of 340 psi  = 170 psi at 73 deg.F)

10" and larger sizes-check with factory for pressure rating.
Important
Maximum pressure for any flanged system is 150 psi unless otherwise  noted. At elevated temperatures the pressure capability of the  flanged system must be derated as noted above.
