Anticorrosion technology of steel sleeve steel insulation pipe

Steel jacket steel insulation steel pipe is widely used in daily production and life, in order to improve the service life of the pipeline and improve the efficiency of the pipeline, it is necessary to pay attention to the maintenance of the pipeline

In particular, pipeline anticorrosion, in the production and use of a little anti-corrosion pipeline, anti-corrosion technology can be considered from the physical and chemical levels, let's follow the steel sleeve steel insulation steel pipe manufacturers together to see

Anti-corrosion technology of steel jacket steel insulation pipe

Spray a uniform and tight coating on all pipes, in order to avoid contact between pipes and other substances, resulting in erosion, which is also a common and simple anticorrosion method, the anticorrosive material is not only painted on the outside wall, but also needs to be painted on the inside wall.

In order to avoid pipe erosion and reduce friction coefficient, the common coatings are amine cured epoxy resin and polyamide epoxy resin. The thickness of the coating is 0.038≤0.2mm. In order to ensure the combination of the coating and pipe wall, the inner wall of the pipe must be solved.

Change the electrode and potential of the metal relative to other surrounding substances, so that the metal is not etched. There are two types of cathodic protection and anti-corrosion method. Cathodic protection is a way to polarize the metal to be maintained into a cathode to avoid metal corrosion.

The leakage current should be reduced as much as possible, and the stray current area should be avoided as much as possible when laying the pipeline, or the overall quality of the insulation layer of the interference pipeline should be improved by adopting various measures, such as plugging and assembling insulation strips

The stray current of the intervention pipeline is discharged back to the power grid that generates the leakage current to remove the corrosion of the pipeline by the stray current.

Steel sleeve steel insulation pipe vibration causes

First, the compressor parameters are unreasonable. The fluctuation range of conveying pressure exceeds the standard and the vibration of compressor itself are the main reasons for excessive vibration of piping system.

The starting phase of each compressor unit does not match, or is not synchronized, which affects each other to produce obvious beating phenomenon. In practice, the vibration of the pipe system is obviously large and small.

There are also different number of compressor units operating will also lead to pipe vibration changes, first, the number of different operating units, the number of exciting forces is different, so the vibration amplitude is different, that is, the amplitude is different. Second, the number of different, phase changes, resulting in amplitude changes

Secondly, the pipeline direction is unreasonable, and the elbow is more, resulting in more exciting force. In the 45° direction of each 90° elbow, an alternating exciting force must be acted on. The more exciting force, the greater the vibration of the pipe system.

There is also an unreasonable pipeline structure, and the header and outlet pipe diameter do not match, that is, the flow area of the header should be greater than 3 times the sum of the flow area of all outlet pipes.
