Abstract

The invention discloses a novel Krah pipe and a preparation process thereof. The preparation process includes the following concrete steps: S1, material mixing; S2, extrusion; S3, heating; S4, winding; S5, cooling; S6, shape modification which means processing an upward socket and a socket of a pipe to a standard size and trimming ports of the pipe to make the appearance of the pipe smooth and regular; and S7, check and warehousing. The preparation process of the invention is reasonable in steps and good in continuity. A flat belt and a U-shaped belt are evenly wrapped on a heated drum mold according to predetermined positions, and so the quality of a pipe welding seam is ensured after cooling. Continuous winding forming is carried out on the mold, the cooling is selected from water cooling, air cooling or a combination of the water cooling and air cooling according to actual situation, and so the crystallization of the product is more compact and uniform. An infrared heating device isused for heating, and so the production safety is improved. Reinforcing ribs are designed in the product, which improves the overall resistance to external pressure of the pipe and is good in use effect.

Description

technical field [0001] The invention relates to the field of carat tube manufacturing, in particular to a novel carat tube and a preparation process thereof. Background technique [0002] Plastic pipes are generally made of synthetic resin, that is, polyester, with the addition of stabilizers, lubricants, plasticizers, etc., and are extruded in the pipe making machine by the "plastic" method. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing and convenient construction, it has been more and more widely used in construction projects. It is mainly used for water supply system piping, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation in housing construction. [0003] In the known technology, there are many kinds of plastic pipes. Generally, the prepared plastic materials are used to make them through a plastic pipe extruder. A plastic p...
