Static pressure instrument ( Pressure, flow, level, etc. ) Bring pressure pipeline

1, guide pressure pipe 14 x2, appropriate USES Ф Ф 18 x3 stainless steel pipe or carbon steel pipes, and other pipeline can be applied. 2, guide pressure pipe connection way can adopt socket welding, butt welding connection or set of way, also can use other connection mode: the root source valve welding methods should be adopted. 3, the roots take appropriate USES source valve gate valve, globe valve or ball valve, also can use other valves. 4, exhaust valve and drain valve appropriate USES a gate or ball valve, stop valve, and close to the instrument; In the following situations without emptying valve and drain valve: a) Instrument is equipped with empty and outlet; b） Steam or toxic medium; c) Strong corrosive medium. 5, medium risk should concentrate discharge. 6, for easy plugging, corrosion, viscous medium and steam should set the isolation tank ( Condensing tank) 。 7, the flow measurement device of high voltage side and low voltage side of the two isolation ( Condensation) The tank should be on the same level. 8, measurement - 29 ℃ under low temperature liquid medium, guide pressure pipes should meet the following requirements: a) Roots take appropriate USES source valve has extended handle cryogenic valves, stainless steel and cold isolation measures: b) After medium from the equipment or pipeline due to instrument in front of the valve between enough length of vaporization section ( To guide the pressure tube temperature close to ambient temperature) And upward sloping installation, also can take in the root source after the valve adopts low temperature resistant spacer guide pressure; c) Besides you have special requirement, the root source after the valve guide pipe does not need to keep cold isolation; d） Low temperature part of the pressure piping material shall be stainless steel. And adopt welding way. 9, measuring more than 350 ℃ high temperature medium, can take the following pressure measures: a) Measure the gas medium, with cold medium gas or no effect on other cold gas counter blowing pressure; b） Measurement of liquid, with cold liquid or no effect on other cold liquid recoil pressure: c) From the meter connector ( Nozzle) Start, use stainless steel pressure guide tube after enough length access source valve after cooling section. 10, guide the piping pressure pipe should be 1:10 slope, measuring liquid tilted upward, downward sloping when measuring gas: required high exhaust valve should be set up and low drain valve. 11, guide pressure pipe should be fixed or steel structure platform, when the inevitable, also can be fixed on the insulation of equipment and pipeline.
