BAIJIAN - Third party testing organization
Fluid transportation refers to the flow of fluid from one location to another along a pipeline (or open channel) at a certain rate. The majority of materials processed in chemical production are fluids、 and conveying these materials between various chemical equipment and machines according to process requirements is an important link in achieving chemical production. There are many types of materials in chemical production、 and the properties of the fluid being transported、 such as density、 viscosity、 toxicity、 corrosiveness、 flammability、 and explosiveness、 vary. In addition、 the pressure of the fluid ranges from high vacuum to 102MPa、 and the hourly conveying capacity ranges from 10-3m3 to over 104m3. Therefore、 there are various forms of fluid conveying machinery and materials used to transport the fluid. When the energy level of the fluid at the feeding point is high enough、 the fluid can flow to the receiving point at the low energy level according to the required conveying amount. Otherwise、 it is necessary to use fluid conveying machinery to supply energy to the fluid. The fluid obtains mechanical energy from the conveying machinery、 which is used to compensate for the energy level difference between the receiving and feeding points、 and to overcome the flow resistance of the fluid when flowing in pipelines or channels. As the flow resistance increases with the increase of flow velocity、 it is required that the mechanical energy per unit weight of fluid added by the fluid conveying machinery increases with the increase of flow velocity. In chemical production、 fluids are mostly transported through closed pipelines. In order to regulate flow、 change flow direction、 and achieve flow separation or merging、 valves、 elbows、 and tees are installed in the pipeline. Pipes and fittings are made of metal materials such as carbon steel、 cast iron、 stainless steel、 copper、 aluminum、 and lead、 or non-metallic materials such as plastic、 ceramics、 glass、 and graphite、 with carbon steel and cast iron being the most widely used
