PE pipe is used to transport gas, liquid or fluid, while it's dirty, it must be clean! Follow we will introduce the useful, maintenance and the method to clean PE pipes.

What is PE Pipe Used For?

PE pipe is a device used to transport gas, liquid or fluid with solid particles connected by straight pipes, pipe fittings and valves. Generally the fluid is pressurized by blowers, compressors, pumps, boilers, etc., and then flows from the high pressure of the pipeline to the low pressure. It can also be transported by the fluid's own pressure or gravity. PE Pipes have a wide range of applications. They are mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.

The Maintenance of PE Pipe

  • Sterilization and Algae Elimination: adding bactericidal agents to the circulatory system, all kinds of bacteria and algae in the circulating water are removed.
  • Sludge Stripping: Add stripping agent to peel off the biological sludge in the pipelineand clean the sludge through circulation.
  • Surface Pre-filming: Put in pre-filming agent to form a dense polymer protective film on the surface to prevent corrosion.
  • Daily Maintenance: adding corrosion inhibitors and scale inhibitors at the same time to prevent calcium and magnesium ions from crystallizing precipitation. And regularly conduct random inspections to monitor the water quality.

Does The PE Pipe Need to be Cleaned?

If the PE pipe has been used for a long time, it is inevitable that there will be some problems such as dirt, blockage, and bacteria. In this case, cleaning is required. The cleaning work is not only a beautiful effect, but more important that it can ensure that the PE pipe can be used normally and smoothly. Regular cleaning work can extend the service life of pipe to a certain extent.

How to Clean The PE Pipe?

1. Chemical Cleaning

Chemical cleaning refers to the temporary modification of PE pipes with chemical agents. It uses the temporarily modified pipes and circulating pumps for cyclic chemical cleaning. The advantage of chemical cleaning is that it is flexible, there is no requirements for the shape of the pipes and the cleaning is thorough.

2. High Pressure Water Jet Cleaning

The high-pressure water spray cleaning method refers to spray cleaning the dirt on the inner surface of the pipe with a high-pressure water flow of 50mpa. The limitation of this method is that the pipe to be cleaned must be a short-distance pipe, because the longer the distance, the smaller the spray intensity of the water stream. As a result, the desired cleaning effect will not be achieved. And the diameter of the pipe must be more than 50cm because the use of high-strength water pressure for the pipe with too small diameter will not achieve the cleaning effect.

3. Ultrasonic Cleaning Method

As the name suggest, ultrasonic cleaning is to use ultrasound to clean PE pipes. This method is also widely used now. The advantage is that it is convenient, quick and highly automated, cleans more thoroughly, reduces environmental pollution and can continue to work.

4. Pipe Cleaner Cleaning

The cleaning of the pipe cleaner mainly relies on the driving force generated by the pump to push the fluid to drive the pipe cleaner, thereby pushing out the dirt in the pipeline to achieve the purpose of cleaning.

5.PIG Pigging

PIG industrial pigging technology relies on the driving force generated by the pump to push the fluid to drive the PIG (pipe pig) forward in the pipe. It discharges the dirt accumulated in the pipeline out of the pipe to achieve the purpose of cleaning. This technology is widely used in cleaning projects such as various process pipelines, oil and gas pipelines in oil fields. Especially for the cleaning of pipelines that transport fluids over long distances, it has advantages that other technologies cannot replace.

The above cleaning methods are suitable for different environments. Choose the right clean method can bring out the cleaning effect. So choose the right cleaning method that suits us according to our actual needs is important. And during the cleaning, the thing we need to pay attention is many factors must be considered. The debris and sewage discharged from the pipes must be treated to prevent the secondary pollution.
