Description
Technical Field
The invention relates to the technical field of pipelines, in particular to a novel corrosion-resistant water flow accelerating drain pipe.
Background
A pipeline is a device for transporting a gas, liquid or fluid with solid particles, connected by pipes, pipe couplings, valves, etc. Generally, a fluid is pressurized by a blower, a compressor, a pump, a boiler, etc., and then flows from a high pressure portion to a low pressure portion of a pipe, or is transported by the pressure or gravity of the fluid itself. The use of pipelines is very widespread, mainly in water supply, drainage, heating, gas supply, long-distance oil and gas delivery, agricultural irrigation, hydraulic engineering and various industrial installations.
At present, in order to consider the service life of the pipeline, the quality requirements of a plurality of manufacturers on the pipeline are very strict, particularly on the purposes of water supply, water drainage, heat supply, gas supply and the like, but the existing pipeline is easy to corrode after being used for a long time, the heat preservation effect is poor, the normal use of the pipeline is influenced, and the maintenance cost is increased.
