The long-term use of the pipeline, the sludge, rust in the pipe solidification caused by the original diameter becomes smaller; the sludge deposition in the pipe to produce hydrogen sulfide gas causes environmental pollution and can easily cause explosion; acid and alkali substances in the waste water are prone to corrosion on the pipe wall; The irregular removal of foreign matter inside can cause blockage of the pipe. Today, Xiao Bian gave everyone a talk about pipe cleaning techniques. Interested friends would like to take a look!
Pipeline cleaning tips
1, chemical cleaning
The chemical cleaning pipeline uses chemical agents to temporarily reform the pipeline, and uses a temporary pipeline and a circulation pump station to carry out cycle chemical cleaning from both ends of the pipeline. The technology has the advantages of flexibility, no requirement on the shape of the pipeline, high speed and thorough cleaning.
2, high pressure water cleaning
High-pressure water jets of 50 Mpa or more are used to perform high-pressure water jet stripping and cleaning of dirt on the inner surface of the pipeline. This technique is mainly used for short-distance pipes, and the pipe diameter must be greater than 50cm. This technology has the characteristics of high speed and low cost.
3, PIG pigs
PIG industrial pigging technology relies on the driving force generated by the pump to push the fluid to drive the PIG (Pipe Purifier) ​​to push forward in the pipe, and the dirt accumulated in the pipe is discharged out of the pipe to achieve the purpose of cleaning. This technology is widely used in various types of process pipelines, oil field oil pipelines and other cleaning projects, especially for long-distance pipeline cleaning fluid transport, with other technologies can not replace the advantages.
Pipeline cleaning process
1. Check the pipeline cleaning object
Before cleaning the pipeline, first of all, it is necessary to clarify the distribution of the pipeline, and to understand the use of life, use, blockage, buried and exposed parts of the building without damage and other issues. Before clearing, please pay attention to its material. In addition to cast iron and ceramics, what materials in the system are also available, such as cement and other structural materials and pipes.
2. Sectional cleaning
In order to facilitate the pipeline cleaning, it is generally divided into several small cleaning segments. The method of segmentation is mainly based on the volume of the pipeline, the height of the floor, the convenience of cleaning, and the possibility of segmentation. Generally, it is better to use three or four floors in a unit.
3. Acceptance
After the pipeline is cleaned, it is checked and checked to see if the pipeline is clear, clean and unobstructed to meet customer requirements.
The above is the introduction of related contents of pipeline cleaning and I hope to help you. For more information on pipe cleaning, please continue to pay attention to information on this site.

Double-Convex Lens, also named Bi-Convex Lens,composing of two convex surfaces, has a positive focal length. DCX Lens is most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object (conjugate ratio) distances is between 0.2 to 5. It is used in beam expanders,projection optics systems, optical viewers applications etc.
We also supply kinds of plano-convex spherical lenses,plano-concave spherical lenses,bi-convex spherical lenses,bi-concave spherical lenses,meniscus spherical lenses,special spherical lenses,achromatic spherical lenses,ball lenses,sphere lenses etc..
