A kind of corrugated pipe processing technology

Abstract

The invention relates to a corrugated pipe processing technology. A corrugated pipe processing device is used to spray the inside of the corrugated pipe. A plurality of corrugated grooves are arranged on the corrugated pipe in the axial direction. The corrugated pipe processing device comprises: a first walking block. , a second traveling block, a rotating frame, a traveling mechanism, and a scraping mechanism. The bellows processing process includes: S1: placing the bellows processing device in the bellows, so that the bellows processing device is in an initial state ; S2: control the traveling mechanism, so that the bellows processing device moves a certain distance along the bellows; S3: control the scraping mechanism to clean the inner wall of the bellows; S4: pass the antiseptic solution through the cleaning pipe The road is sprayed on the inner wall of the corrugated pipe; S5: Control the traveling mechanism, so that the corrugated pipe processing device is switched to the initial state; S6: Repeat S2, S3, S4, S5, so that the corrugated pipe processing device is completely aligned The bellows are sprayed.

Description

technical field [0001] The invention relates to the field of corrugated pipe processing and manufacturing, in particular to a corrugated pipe processing technology. Background technique [0002] Corrugated pipes mainly include metal corrugated pipes, corrugated expansion joints, corrugated heat exchange pipes, diaphragm bellows and metal hoses, etc. Corrugated pipes are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy and other industries. The pipe is easily affected by the use environment and the conveying medium, and the chemical reaction causes corrosion. Corrosion causes great damage to the metal bellows, because no matter how good the external coating of the pipe is, and how advanced the external anti-corrosion technology is, if the internal anti-corrosion is not carried out, it will be Causes premature scrapping of corrosion, while internal corrosion is concealed, and its existence is often ignored by people. At th...

Problems solved by technology

At the same time, due to the particularity of the conveying medium, the internal corrosion of the pipe is very serious, even far exceeding the external corrosion. In the prior art, spraying is often used to spray the inside of the pipe. Because the inner wall of the corrugated pipe is uneven, impurities are likely to remain , when the anti-corrosion layer is sprayed without cleaning the impurities, the impurities in the pipe will easily cause the coating to fall off, thereby affecting the service life of the pipe. The present invention is designed to solve the above problems
