62808ol.com1 General Principles
1.0.1 This regulation clarifies the design division between instrumentation and piping, and coordinates the work between the two disciplines to improve the design quality and ensure the design progress. 1.0.2 This regulation applies to the design division between the instrumentation and piping in engineering design. In the division of labor for field instrument source extraction and connection components, because it includes the installation of instruments on equipment, it also includes the design division of labor with the equipment specialty.
1.0.3 When implementing this regulation, it should also comply with the provisions of the relevant national standards in force. 17

2.0.1 The principle of design division of labor between the automatic control specialty and the pipeline specialty is that before the instrument is installed, the pipeline should be a closed system. Generally, the materials within the closed system are the responsibility of the pipeline specialty, and the materials outside the closed system are the responsibility of the automatic control specialty.
2.0.2 The design division of labor between the automatic control specialty and the pipeline specialty in field instrument source extraction and connection components is divided into the following four situations:
1 The purchase and installation of instruments and installation components are all the responsibility of the automatic control specialty. 2 Only the purchase of the instrument part is the responsibility of the automatic control specialty, and the purchase of installation components and the installation of instruments and their components are the responsibility of the pipeline specialty.
3 The division of labor for the purchase and installation of instruments and their installation components shall be determined according to specific circumstances. 4 The purchase and installation of instruments and installation components shall not be the responsibility of the automatic control department. The division of labor for various field instruments is listed in Table 2.0.2 and Figures 2.0.2-1 to 16 according to the above four situations. If the design division of a certain instrument is not included in the four situations stipulated in this regulation, or it is purchased as a complete set with the equipment, the professional division of labor should be determined by negotiation between the pipeline department and the instrument department according to the specific situation. 18
