The invention discloses a
pollution-free, high-efficiency and long-distance
pipe installing and cleaning method, and belongs to the field of
pipe cleaning. The
pollution-free, high-efficiency and long-distance
pipe installing and cleaning method comprises the following steps: installing a ball sending device and a ball receiving device, temporarily testing the leakage and the pressure of a
system, sending a
diameter-measuring ball,
drying, derusting, passivating, chemically
degreasing,
drying, inspecting and accepting, performing
nitrogen protection and transferring, wherein in the derusting, passivating and chemically
degreasing steps, a pipe-cleaning
train of a pipe cleaner-a
chemical agent-a pipe cleaner is used, namely the
chemical agent is integrally injected into a space between a first pipe cleaner and a second pipe cleaner; the
chemical agent comprises a passivating agent or a
degreasing agent; the degreasing agent adopts the formulation as follows: 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. By the
pollution-free, high-efficiency and long-distance pipe installing and cleaning method, synchronous and high-efficiency operation of physical cleaning and
chemical cleaning of a long-distance pipe can be achieved.
