Common PPR pipe blockage causes and solutions

Time:2019-03-12

What are the causes of pipe blockage?

1. Due to the long-term lack of cleaning, the sludge and rust and scale substances in the pipeline are solidified, causing the PPR pipeline to be directly small and blocking the flow rate of the water body;

2. The acid and alkaline chemicals in the wastewater in the drainage pipe will invade and corrode the pipeline for a long time, causing corrosion of the pipe wall;

3. In life, improper use causes foreign matter in the pipeline to be piled up, and irregularly removes and blocks the pipeline;

4. The sediment deposited inside the pipeline will not be cleaned for a long time, and hydrogen sulfide gas may be generated, which not only causes environmental damage, but also can cause explosion when it is serious.

Pipeline blockage affects normal life, we need to choose home water pipes and pay attention to some details. But we may ask, usually the water pipes have been installed, it is impossible to disassemble and clean them frequently. So what is the solution?

First, chemical cleaningWe can use chemical agents for pipe cleaning. This method is carried out inside the pipe. There is no requirement for the shape of the pipe, the speed is fast, and the cleaning is thorough. When the pipeline is temporarily modified, a temporary chemical cleaning is performed on both sides of the pipeline using a temporary pipeline and a circulating pumping station.

Second, high pressure water cleaningThe inside of the pipeline is injected and cleaned using a high pressure water pressure, and is cleaned by a high-pressure water jet having high strength and high pressure. However, this technology has certain limitations, and can only be applied to short-distance pipelines, and the diameter needs to be more than 50cm to facilitate cleaning;

Third, PIG cleaner cleaningThe driving force generated by the pump pushing fluid drives the PIG cleaner to push forward in the tube, and the dirt and debris accumulated on the inner wall of the pipe are discharged out of the pipe. PIG cleaning technology is widely used in various process pipelines, oilfield oil and gas pipelines and other cleaning projects, especially for long-distance transport of fluid pipeline cleaning, with other technologies can not replace.
