[49 CFR 192.165(a)] B. Each liquid separator used to remove entrained liquids at a compressor station must: [49 CFR 192.165(b)] 1. have a manually operable means of removing these liquids; [49 CFR 192.165(b)(1)] 2. where slugs of liquid could be carried into the compressors, have either automatic liquid removal facilities, an automatic compressor shutdown device, or a high liquid level alarm; and [49 CFR 192.165(b)(2)] 3. be manufactured in accordance with Section VIII of the ASME Boiler and Pressure Vessel Code (BPVC) (incorporated by reference, see §507) and the additional requirements of §1113.E except that liquid separators constructed of pipe and fittings without internal welding must be fabricated with a design factor of 0.4, or less.
