¶ American Petroleum Institute¶ Manufacturer's Standardisation Society¶ American National Standards Institute¶ International Organization For StandardizationThe API standard 598: Valve Inspection and Testing, covers the testing and inspection requirements for gate, globe, check, ball, plug and butterfly valves. It has acceptable leakage rates for liquid as well as gas testing. All valves built to the various API standards are required to meet API-598 leakage criteria prior to shipment from the manufacturer or supplier.API 598 states for shell and BACK SEAT tests, no visible leakage is permitted.

  • Insulation gas leakage detector

    Insulation gas leakage detector SF6 LaserGasTest is based on laser photo-acoustic spectroscopy. This method is well known and widely used for goals of detection of various chemicals when efficiency matters. For example, SF6 LaserGasTest can detect the presence of about 10 ppb of sulfur hexafluoride, which is equivalent to the detection of a sulfur hexafluoride molecules of the 100 000 000 (one
