Problems solved by technology

At present, most of the water pipes used for municipal water delivery are processed from a single material. The pipes have poor corrosion resistance, weak impact resistance, and poor thermal insulation performance during use, resulting in a short service life of the pipes. For this reason, further research is needed. Research

Abstract

The invention discloses an underground long-distance water conveying pipe for municipal engineering and a production process thereof, and relates to the field of water conveying pipes. The water conveying pipe comprises an inner sleeve. A buffer pipe is arranged on the outer side of the inner sleeve. An outer sleeve is arranged on the outer side of the buffer pipe. Holes are formed in the outer sleeve in the circumferential direction. Elastic metal wires are arranged in the holes. The inner sleeve and the outer sleeve are made of same materials. The inner sleeve and the outer sleeve are made of the raw materials of, by weight, 50 to 95 parts of polyvinyl chloride resin, 6 to 15 parts of butyl rubber, 4 to 20 parts of nano activated carbon fiber, 3 to 8 parts of diethyl phthalate, 7 to 10 parts of thermal expansion graphite, 9 to 15 parts of reinforced fiber, 4 to 7 parts of silicon dioxide, 3 to 4 parts of compatilizer, 1 to 8 parts of lubricant, 2 to 10 parts of antioxidant and 0.2 to3.5 parts of flexibilizer. The long-distance water conveying pipe is high in antibacterial property, resistant to corrosion, resistant to high pressure, good in heat preservation performance, high intoughness, resistant to bending, good in water quality when used for conveying water, light in weight, long in service life, capable of saving energy and environmentally friendly, and is of a multi-layer structure.

Description

technical field [0001] The invention relates to the field of water delivery pipes, in particular to an underground long-distance water delivery pipe for municipal engineering and a production process thereof. Background technique [0002] The water pipe refers to the pipe from the water source to the water plant (raw water transport) or from the water plant to the water distribution network (purified water transport) when the water plant is far away from the water supply area. At present, most of the water pipes used for municipal water delivery are processed from a single material. The pipes have poor corrosion resistance, weak impact resistance, and poor thermal insulation performance during use, resulting in a short service life of the pipes. For this reason, further research is needed. Research. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose an underground long-distance water pipe for ...
