Pipeline layout design of clean workshop

When designing the pipeline layout of the clean workshop, the layout of the process and non-process pipelines should be coordinated firstly, according to the process flow and combined with the equipment layout, in advance of meeting the requirements of process, installation and maintenance, safety, neatness, beauty, etc. The investment is the most economical and the expenditure is the smallest; in the workshop with air cleanliness requirements, the supervisor of the system should be arranged in the technical mezzanine, technical lane or technical shaft; there are air purification system pipelines in the mezzanine system, including supply and return air pipes, exhaust pipes. Air system pipelines, dust removal system pipelines, these system pipelines are characterized by large diameter, many and wide pipelines, and are the leading pipelines in the technical interlayer of the clean workshop. The division of the system is affected by factors such as the division of the system, and whether the pipeline arrangement is ideal directly affects the technical sandwich design.

The common ways of concealing pipelines include technical interlayers, pipeline shafts and technical corridors; there are several forms of technical interlayers, only the top of which has technical interlayers, which is more common in single-storey workshops; For auxiliary rooms such as air-conditioning room and power, the upper space of the air-conditioning room can be used as the lower mezzanine of the upper clean workshop. The pipelines required for the production positions are all led down by the main line in the interlayer. Generally, small-diameter pipelines and some electrical pipelines can be buried in the wall. The pipeline shafts of the first floor and high-rise clean workshops shall be closed with reinforced concrete slabs at least every other floor. Pipeline materials should be selected according to the physical and chemical properties and working conditions of the conveyed materials. The materials used should ensure that they meet the process requirements, are reliable in use, do not adsorb and pollute the medium, and are convenient for construction and maintenance; Pipeline materials, valves, and pipe fittings for conveying purified water, water for injection, sterile media and finished products should be made of low-carbon high-quality stainless steel, and the pollution of materials to drugs and process water should be reduced. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean workshops and clean workshops.

All kinds of pipes in the clean pharmaceutical cleanroom should be designed and installed to avoid parts that are not easy to clean. In order to prevent materials from staying in the equipment and pipes and causing pollution, the inner wall of the equipment should be smooth; the pipe design should reduce the number of branch pipes, For pipe fittings, valves and blind pipes, in order to facilitate cleaning and sterilization, the parts that need to be cleaned and sterilized should be easy to disassemble and assemble, and the cleaning port should be set up for those inconvenient to disassemble; Sterilization measures should be taken for the pipeline of bacteria medium or sanitary thin-walled detachable pipeline should be adopted, and there should be no blind pipes that cannot be sterilized; flanges, threads or other connecting pipe fittings with excellent sealing performance should be used for the connection between pipelines and valves. When connecting flanges, it is advisable to use butt flanges and looper flanges that are not easy to accumulate liquid; for the pipelines conveying purified water and water for injection, branch pipes and valves should be minimized. Circulation, so that the water for injection can be returned to the main pipe through the return pipe of the branch pipe when not in use, so as to prevent the breeding of bacteria in the branch pipe due to the retention of water.
