摘要： A fluid flow rate control method is provided that uses a flow rate range variable type pressure type flow rate control device provided with at least two or more parallel fluid passages disposed between the downstream side of a control valve of the control device and a fluid supply pipe passage, and orifices having different fluid flow rate characteristics are respectively interposed in parallel fluid passages to pass fluid in a first flow rate region through one orifice for flow rate control, and to pass fluid in a second flow rate region through at least another orifice for flow rate control. Flow rate characteristics of the respective orifices are selected so that a maximum controllable flow rate of fluid in the first flow rate region at low flow rate is smaller than 10% of a maximum controllable flow rate in the second flow rate region at high flow rate.

摘要： A pipe joint which does not generate fine particles even though being repeatedly mounted and demounted is provided. A pipe joint includes first and second joint members having fluid channels communicating with each other, an annular gasket to be interposed between abutting end surfaces of the both joint members, and a nut configured to couple the joint members. The nut is provided with an inner surface treated layer. The inner surface treated layer includes a Co (cobalt)-P (phosphorous) alloy metal coating provided on an inner surface of the nut and a fluorine coating provided on the surface of the alloy metal coating.
