Use of pipes

Material, pressure, medium, temperature, investment, and so on

I think when using it, one should pay attention to potential corrosion issues. Also, if the material is exposed to high or low temperatures, measures for insulation or cooling should be considered, as heat loss in such situations can be significant

The safe use of pressure pipelines depends not only on the quality of design, manufacturing, installation, and inspection, but more importantly on the safety management during operation； It is basically similar to the safety requirements for pressure vessels; specifically, the main points to pay attention to are: 1. The start-up and shutdown procedures for the pipelines should be reasonable, the operations should be carried out smoothly, and changes in temperature and pressure should occur gradually ； The range of temperature and pressure fluctuations should be well controlled. 2. Operation at excessive temperature, pressure, or load is strictly prohibited. 3. Strictly control the alternating loads during pipeline operation. 4. Strictly control the content of corrosive media in the pipelines. 5. Strengthen routine inspections during pipeline operation to promptly identify and eliminate safety hazards. 6. Strictly implement the regular inspection system for pressure pipelines. For reference!

What was said upstairs covers everything; one additional point is that the flow rate and pressure of the pipelines must be kept within reasonable ranges.

Material, pressure, medium, temperature, investment

Environmental impacts should also be considered, as well as the use of safety valves

There are many things to be careful about when using pipelines. Actually, the person above has already explained the main points quite clearly, so I’ll also share my own views: 1. After construction is complete, before putting the pipeline into use for the first time, it must be inspected thoroughly. 2. During purging, it is essential not to use too high a pressure, and the pipes must not be damaged. 3. Operation at excessive temperature, pressure, or load is strictly prohibited. 4. Strictly control the content of corrosive media in the pipelines. 5. Strengthen routine inspections during pipeline operation to promptly identify and eliminate safety hazards. 6. Strictly implement the regular inspection system for pressure pipelines. 7. No one should stand or walk on pipes, especially those with insulation layers. 8. For pipes that are no longer in use, it is necessary to primarily relieve pressure or empty the contents within the pipes. It’s just my personal suggestion

Refer to the design codes for industrial metal pipes

1. Pay attention to the material of the pipes, the type of fluid, pressure, flow rate, and temperature; it is necessary to control the flow rate (to avoid exceeding the maximum design pressure and flow rate, as this can lead to accidents)； 2. Pay attention to the corrosion protection of pipelines; for buried pipelines, it is advisable to use an external anti-corrosion coating along with sacrificial anode and cathodic protection measures, while overhead pipelines should be coated with rust-proof paint as well as an outer surface coating ； 3. Establish comprehensive rules and regulations during operation and ensure their strict implementation ； 4. During operation, maintenance and inspections should be carried out at regular intervals. Just my personal opinion, for reference only, hehe!

In addition to the standard process parameters, proper external anti-corrosion treatment for the pipes must be carried out

First, select the material carefully, taking into account costs as well as construction and maintenance aspects

(1) Various process operation parameter values, operational status, system balance； (2) Whether the pipeline is in normal operating condition, and the sealing status of valves and fittings ； (3) Are the insulation layer and anti-corrosion layer in good condition? ； (4) Pipeline vibration conditions ； (5) Whether there is friction between the pipeline valve, the pipeline, and adjacent components ； (6) Is the lubrication of operating mechanisms such as valves in good condition? ； (7) Are the safety accessories in good condition? ； (8) Are there any leaks, seepages, drips, or spills in the piping system?
