Steel pipe inner coating solidifying device used for high-temperature environment

Abstract

The invention discloses a steel pipe inner coating solidifying device used for a high-temperature environment and aims to solve the problems of the prior art. The steel pipe inner coating solidifying device comprises a sliding rail, supports, a chain, a driving wheel, a driven wheel, a driving rod and a frequency changer, each support is of a hollow structure in the shape of a Chinese character 'kou', the sliding rail is supported by the supports, the driving wheel and the driven wheel are arranged at two ends of the sliding rail, one end of the chain is nested in the driving wheel while the other end of the same is nested in the driven wheel through the sliding rail, and the frequency changer is connected with the driving wheel through the driving rod. The steel pipe inner coating solidifying device is easy to operate, safe, stable and capable of realizing continuous solidifying processes, and product quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and automatic control, and in particular relates to a steel pipe inner coating curing device used in a high-temperature environment. Background technique [0002] Steel pipe is a common metal material for conveying fluids, and it is widely used in conveying oil, gas, water and other media. Since metal materials are easily affected by the external environment and internal media during use, the service life is shortened. In order to prolong the service life of steel pipes, the commonly used delay method is to adjust the external or internal Treat for corrosion protection. [0003] There are three major elements in the internal anti-corrosion treatment of steel pipes: one is the coating material; the other is the coating process; the third is the high temperature curing of the coating. Among them, the internal coating generally uses modified epoxy polymer materials; the coating pro...

AI Technical Summary

Problems solved by technology

This method of operation can easily lead to:

[0005]One is manual operation under high temperature environment (50-80℃), which is extremely unsafe and does not meet the requirements of HSE;

[0006]Secondly, due to the intermittent manual movement of the steel pipe, the operator continuously moves in and out of the curing room to move the steel pipe, and the curing temperature tends to fluctuate;

[0007]Third, the moving speed of the steel pipe cannot be controlled, which may easily cause bruises and product quality fluctuations, and the rework rate is high

This method is a great progress by using the mechanical arm to tilt the steel pipe instead of manually moving the steel pipe, but because the steel pipe is more unevenly stressed and moves forward at an "explosive" non-uniform speed, it is easier to damage the outer surface of the steel pipe, and the process is still a batch production

The above curing processes all have technical problems such as unsafe high temperature operation, temperature fluctuations, non-uniform movement of steel pipes, intermittent production, etc., which easily cause fluctuations in product quality
