How reasonable is the brewery pipeline layout (Lower)

How to arrange the equipment pipeline of the brewery reasonably, haolu beer equipment manufacturer has introduced the basic requirements of the purpose of the pipeline layout and the general rules of the layout, if you want to know, you can click to see how the brewery pipeline is arranged reasonably (On). Xiao Bian continues to share several factors that should be considered in the layout of pipelines. 1) Medium factors in the early stage of pipeline layout drawing, first of all, it should be classified according to the medium transported in the pipeline. Pipes for transporting flammable, explosive, toxic and corrosive materials shall not be laid in living rooms, stairs, corridors and doors, safety valves, explosion-proof films, flame arresters, water seals and other fire and explosion-proof devices should also be set on these pipelines, and vent pipes should be led to designated locations or above 2m above the roof (The specific height should follow the requirements of relevant national codes); Pipelines with corrosive materials are not recommended to be laid above the passage and above or inside the parallel pipelines; There should be a certain slope when laying pipelines. The slope direction is generally along the direction of Medium Logistics, and the slope is generally 1/100 ~ 5/1000, liquid material pipeline with low viscosity can take about 5/1000, material pipeline with solid can take about 1/100 ( It is difficult for the general utility tunnel to meet the pipeline slope requirements, because the medium flow direction of each workshop is not unified and unidirectional. If the pipeline slope is considered according to the medium flow direction, the height of the pipe support and pipe support surface will be inconsistent, or the pipe holders are inconsistent, and the general beer factory usually ignores the slope of the pipeline); The vacuum pipe should be as short as possible, try to reduce the elbow and valve, in order to reduce the resistance loss, to achieve a higher degree of vacuum. 2) Operational factors in order to facilitate on-site construction, operation and maintenance of the pipeline, the pipeline should be arranged as intensively as possible on the pipe rack of the integrated pipe gallery, arranged in parallel and straight lines, with fewer turns and intersections as far as possible, do not hinder the opening of doors and windows and the installation and maintenance of equipment, valves and pipe fittings, and the valves of parallel pipelines should be staggered as far as possible; Pipelines with many branch pipes should be arranged on the outside of parallel pipelines. When the branch pipes are led out, the gas pipelines should be led out from the top and the liquid pipelines should be led out from the bottom, pipes should try to avoid 'air bags', 'pockets' and 'cecum '; The pipeline should be laid along the wall as far as possible, or arranged on the pipe rack fixed on the wall. The distance between the pipeline and the wall is based on the principle of being able to accommodate pipe fittings, valves and convenient installation and maintenance. 3) Safety factors in order to prevent the medium from flowing in the pipe and causing electrostatic accumulation, grounding measures should be taken for the pipes of flammable and explosive media to ensure safe production. Thermal compensation should be considered in the pipeline for long-distance transmission of steam or other hot materials. Compensator and sliding bracket should be set between two fixed brackets. The clear height of the overhead pipeline and the ground of the utility tunnel should not only meet the technological requirements, but also be convenient for operation and maintenance. When the pipe gallery crosses the passage, the net height requirement (Lowest Place): Not less than 2m when passing through the sidewalk; Not less than 4 when passing through the highway. 5 m; Not less than 6m when passing through the railway; 5m above the ground when passing the main traffic lines of the factory. According to the code for fire protection design of buildings (GB50016)7. 1. Article 8: The net width and clearance height of the fire lane should not be less than 4. 0 m; According to the code for design of factory and mine roads (GBJ 22) And 'code for design of roads in petrochemical enterprises' (SHJ23) The specified minimum clearance height of generally meets the following requirements :(1)Main road 5. 0 m; (2)Secondary roads and fire roads 4. 5m Considering the comprehensive fire safety, the pipe gallery must ensure that the clearance from the road surface to the bottom of the pipe rack meets 5. 0m
