Tube is often used in the automation instrument piping design of petrochemical and chemical plants. Based on the standards and specifications at home and abroad,this paper compares and analyzes the differences between Tube and Pipe,elaborates the characteristics and advantages of Tube itself,describes the effect of Tube surface finish,material, hardness and wall thickness on the instrument piping connection. By comparing various types of standard specifications and combining with engineering design experience, the commonly used dimensions,wall thickness selection,temperature and material effects on Tubes for instrument mounting are explained. The principle,characteristics and applications of the ferrule connectors are introduced.The proper selection of tube fittings and ferrule connectors will bring convenience to the instrument piping engineering.
