Pipes between devices in the factory

Thread Content

The numbering and labeling of the pipes between devices in the plant (also known as the inter-device connection pipes) are shown in Figure 7-1. The boundary between the pipeline numbers of the external tube and the internal tube of the unit is usually located 1 meter outside the unit’s boundary line. 7-1 Numbering and labeling of pipes between units in a plant (also known as inter-unit connection pipes). I. The method for numbering the pipe IDs of these external pipes is the same as that used for numbering pipe IDs within the units. II. The pipes between units include process material pipes as well as pipes for auxiliary materials and utility materials. The second part of the pipe number, which represents the process step (main item) number, should be replaced by a \"unit\" number (or a number corresponding to its name). This number must differ from the number of the unit to which it is connected, such as the number \"502\" in Figure 7-2. It consists of two (or three) digits, as determined by the plant engineering design manager. Example: Process material pipe PL-502001-100-B2A-H for auxiliary materials; utility material pipe CWS-502001-300-AIA
