Pollution-free, high-efficiency and long-distance pipe installing and cleaning system

Abstract

The invention discloses a pollution-free, high-efficiency and long-distance pipe installing and cleaning system, and belongs to the field of pipe cleaning. The pollution-free, high-efficiency and long-distance pipe installing and cleaning system comprises a ball sending device, a ball receiving device, pipe cleaners and a chemical agent, wherein the ball sending device and the ball receiving device are installed at the two ends of a pipe to be cleaned; the pipe cleaners and the chemical agent form a pipe-cleaning train of the pipe cleaner-the chemical agent-the pipe cleaner; the pipe cleaners comprise a first pipe cleaner and a second pipe cleaner; the first pipe cleaner is sent into a pipe to be cleaned and at a 10cm position from an inlet; the second pipe cleaner is put into the ball sending device; the chemical agent is positioned between the two pipe cleaners; the chemical agent comprises a passivating agent or a degreasing agent; the passivating agent comprises 2-3% of sodium nitrite, 0.5-1% of trisodium phosphate and 96-97.5% of water; the degreasing agent comprises 2-3.5% of sodium tripolyphosphate, 1-2% of sodium carbonate, 0.5-1.5% of sodium hydroxide, 0.2-0.4% of sodium borate, 0.1-0.2% of disodium ethylenediamine tetraacetate, 0.05-0.1% of sodium oleate, 0.05-0.1% of sodium dodecyl sulfate, 0.05-0.1% of alkylphenol ethoxylate and 92.1-96.05% of water. The pollution-free, high-efficiency and long-distance pipe installing and cleaning system can achieve synchronous and high-efficiency operation of physical cleaning and chemical cleaning of a long-distance pipe.

Description

Technical field [0001] The invention relates to the technical field of pipeline cleaning, and more specifically, to a pollution-free, high-efficiency, long-distance pipeline installation and cleaning system for pipe cleaner-synchronous passivation and degreasing construction. Background technique [0002] The raw material steel pipe, steel plate, stainless steel, etc. of the pipeline will form a rolled skin during rolling; the pipeline will form rust, welding slag and oily anti-rust agent and dust coated on the pipeline during the manufacturing, storage, transportation and installation process. , Sand, cement, insulation materials and other impurities. The above-mentioned various impurities such as rolling, rust, welding slag, rust inhibitor and silt seriously affect the normal use of the pipeline, so it is necessary to clean the pipeline to restore the surface of the material itself. [0003] There are three main methods for pipe cleaning: 1. Chemical cleaning. Chemical cleaning ...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the disadvantages in the prior art that cannot adapt to the long-distance flammable and explosive gas transportation pipeline and need to carry out the degreasing operation and the pigging operation at the same time, the present invention provides a pollution-free and efficient long-distance pipeline installation and cleaning system
