Working principle of electroplating processing electric heating tube ferrule joint

Working principle of electroplating processing electric heating tube ferrule joint

It is to insert the steel pipe into the ferrule, lock it with the ferrule nut, resist the ferrule, cut into the pipe and seal. It does not need welding when it is connected with the steel pipe, which is conducive to fire prevention, explosion-proof and high-altitude operation, and can eliminate the disadvantages caused by inadvertent welding. Therefore, it is a relatively advanced connector in the pipeline of the automatic control device of the oil refining, chemical, petroleum, natural gas, food, pharmaceutical, instrumentation and other systems. Suitable for oil, gas, water and other pipeline connections.

The electroplating processing electric heating tube tube joint consists of three parts:

Fitting body, ferrule, nut. When the ferrule and the nut sleeve are inserted into the joint body on the steel pipe, when the nut is tightened, the outer side of the front end of the ferrule fits the conical surface of the joint body, and the inner edge evenly bites into the seamless steel pipe to form an effective seal. Compression fittings are corrosion-resistant, high-pressure resistant, easy to install, and durable.

Precautions for local silver plating and pickling of stainless steel ferrule joint nuts of electroplating processing electric heating pipes

1. Sulfuric acid will generate a lot of heat when it meets water. When adding it, do not add too much at one time. At the same time, pay attention to ventilation and heat dissipation to ensure that the sulfuric acid liquid does not boil or splash and hurt people.

2. The sulfuric acid tank should be equipped with a flame-retardant PP hood, and a customized PP tank cover should be covered when the operation is stopped to prevent excessive volatilization and pollution.

3. After pickling, it needs to be cleaned with pure water several times to ensure that too much sulfuric acid liquid is not brought in before entering the next process, so as to avoid increasing the pickling of the next plating solution.

4. After the sulfuric acid is heated, the pickling effect will be significantly enhanced, but there is a certain danger, which requires professionals to operate. Improper operation will cause danger.

5. The used waste sulfuric acid cannot be discarded casually. It needs to be collected and handed over to a special environmental protection treatment company for processing to avoid harm to the environment.
