An object of the present invention is to provide a steel pipe for high-pressure hydrogen having high strength and a low fatigue crack growth rate in a region in which ΔK, which is related to fatigue crack growth resistance, is 10 MPa·m1 / 2 or less. A steel pipe for high-pressure hydrogen, the steel pipe having a chemical composition containing, by mass%, C: 0.05% to 0.60%, Si: 0.001% to 2.0%, Mn: 0.01% to 5.0%, P: 0.030% or less, S: 0.010% or less, N: 0.010% or less, Al: 0.0001% to 1.00%, O: 0.010% or less, H: 0.00010% or less, and a balance of Fe and incidental impurities and a metallic microstructure including, in terms of area fraction, 3% or less (including 0%) of retained austenite, in which the number of inclusions having an aspect ratio of 2.0 or more and a length of 10 um or more is 15 / 100 mm2 or less.

The present application relates to a kind of multi-point cooperative gas emergency shutdown positioning method based on gas monitoring system, belong to the field of automation control technology. Among them, the method includes: real-time acquisition multi-source alarm signal;And the analog quantity and switch quantity of the multi-source alarm signal are uniformly converted into digital processing code;Multi-source alarm signal digital processing code is analyzed in real time to obtain alarm priority and associated equipment address, and data accuracy is verified by actual combat coefficient correction model;Combining dynamic networking and cooperative decision mechanism generates shutdown path;Shutdown path is executed, and execution result is fed back to host computer monitoring platform in real time, and field alarm lamp state and broadcast system are updated simultaneously;Through host computer monitoring platform, alarm history curve, equipment state and linkage logic of shutdown operation are recorded, and manual reset interface is provided to remove shutdown state. Efficient processing and accurate response of gas leakage accident are realized.

The invention discloses a temperature control circuit system applied to cesium furnace heating, and belongs to the technical field of cesium metal production. Comprising a 220V alternating current power supply, a short circuit protection unit, a direct current voltage stabilization unit, a main control chip, a temperature heating unit, a temperature control unit, a temperature detection unit and an LCD display unit. The short circuit protection unit is electrically connected with the 220V alternating current power supply and the direct current voltage stabilization unit, the temperature heating unit is electrically connected with the main control chip and the cesium furnace, the temperature control unit is electrically connected with the main control chip and the temperature detection unit, and the temperature detection unit is electrically connected with the temperature control unit and the cesium furnace. Heating and cooling of the cesium furnace can be controlled, the constant-temperature state can be maintained, it is guaranteed that metal cesium cannot be condensed into a solid state after being gasified in the cesium furnace, solid cesium is prevented from blocking the interior of a pipeline, and therefore smooth conveying of gaseous cesium by the cesium furnace is guaranteed. The system also rapidly protects the circuit system through the short-circuit protection unit.
