This makes it the industry standard for handling &#8220;sour&#8221; gases and liquids containing hydrogen sulfide or high salinity.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,1,0\"><b data-path-to-node=\"3,1,0\" data-index-in-node=\"0\">Extreme Pressure Performance<\/b>: Capable of operating at pressures up to PN 250 (Class 1500), it delivers premium mass flow accuracy in deep-water production or high-pressure gas injection.
