Problems solved by technology

However, this technique can also cause clogging
As the abrasive is moved back and forth repeatedly, it will gradually become mixed with the sludge removed from the pipe surface, weakening or reducing the cleaning effect

Embodiment Construction

[0024] Figures 1 through 4 of the accompanying drawings and Figure 6 A system and method for repairing a pipeline is illustrated according to an exemplary embodiment of the invention. The method can be used to repair pipes in any type of piping system, including water pipes, air pipes, sewer pipes, oil pipes, pipes in chemical plants, pipe systems on ships and other ships, air conditioning pipes, storm drainage systems, fire sprinklers water system etc. It will extend the life of the piping system and reduce or avoid the cost of replacing all or part of the piping system.

[0025] Figures 1 and 2 illustrate a simplified view of a section 10 of a piping system to be repaired. It will be understood that typical piping systems will include joints, elbows, elbows, connecting pipes, etc., which are not shown in the drawings. Figure 1 illustrates the pipe cleaning phase of the method, while Figure 2 illustrates the pipe coating phase. The system shown in FIG. 1 basically include...

Abstract

A pipe repair method and system in which the pipe is first cleaned and then coated with a suitable coating material. During the cleaning step, particles of pressurized air and abrasive material are pumped into the first end of the pipe, while suction is applied to the second end of the pipe by means of a vacuum pump to improve flow along the entire length of the pipe. The coating material is then pumped in at one end of the pipe that has been cleaned, while suction is applied at the other end. In each step, the suction flow rate is higher than the output flow rate, so that the mixture is oriented towards the second end. This method can be used to coat and clean different parts of the piping system by successively connecting the input material to different connection ports in the system.

Description

technical field [0001] The present invention relates to a system and method for repairing pipelines by removing sludge or blockages in the pipelines and then coating the pipelines with a coating material. Background technique [0002] All types of pipes, such as water pipes, air pipes, sewer pipes, industrial fuel pipes, chemical plant pipes, etc., are prone to build up deposits or fouling on the inner surfaces of the pipes. One of the reasons for this is corrosion or rust on the surface of the pipe. Another cause of fouling is the deposition onto pipe surfaces of sludge from materials flowing through the pipes, such as lime or other solid deposits from water in water pipes. These deposits result in a narrowing of the pipe diameter, reducing throughput, and causing corrosion pitting, which ultimately compromises the integrity of the pipe and leads to premature failure of the pipe system. [0003] Repairing existing piping will reduce the need for complete or partial replac...
