Division of labor for the design of instrument air branch pipelines

In industrial installation projects, the division between the piping design for the branch instrument air pipelines and the automatic control design is usually carried out in accordance with the specific requirements of the project, as well as relevant engineering standards and specifications. These requirements and specifications may vary depending on the **region and location, as well as the client’s project requirements. Generally speaking, during the design phase, it is important to establish detailed engineering subcontracting units and tasks. **Piping design **usually includes:** 1. The layout design of the pipelines, including pipe diameter, pipe material, and the selection of supports. 2. Selection of pipe fittings and valves. 3. Calculation of pipeline pressure and flow rate. 4. Construction drawing design of pipelines, etc. **Automatic control design typically includes: 1. Selection and placement of instruments. 2. Logical design of the control system. 3. Wiring and signal transmission design. 4. Software configuration of the control system, etc. Regarding the material selection for the instrument air branch pipelines, **there is no universal requirement to use white steel pipes** (also known as stainless steel pipes). In fact, the material of the pipeline needs to be determined based on factors such as actual operating conditions, the medium, pressure, and temperature. Common materials used in engineering include carbon steel, stainless steel, copper pipes, alloy pipes, etc. As for whether the single-threaded end of the air supply ball valve connected to the internal thread (i.e., the fitting with external threads) falls under piping or automation, it is usually determined based on the engineering classification and contractual responsibilities. In some cases, this may fall under the scope of piping work, while in other cases it may be considered part of the automatic control system. Therefore, the most accurate method of classification is to determine it based on the specific requirements of your project and the construction division plan. In the pre-design and pre-construction phase, there is usually a detailed technical agreement or construction specification that specifies the boundaries of work among various specialties as well as the relevant technical requirements. In uncertain situations, it is advisable to consult the project’s engineering management team or review the specific project contract documents and technical standards. .
