How to maintain stainless steel flanges to avoid some common faults?

2021年12月27日

We all know that large chemical companies or pipeline equipment companies have flanges, and flange dismantling equipment can even be seen on site. What is a flange? Like bricks and tiles, it plays a crucial role in the overall operation of equipment and pipeline transportation. All equipment needs maintenance, otherwise, even if the design is exquisite, it will suffer losses and cause safety failures, as well as hidden dangers.


What is a stainless steel flange? Made of stainless steel material, there is also a connecting disc with screw holes. Everyone has seen pipelines, what is the one connecting them? It's just a flange! We can also find some holes on top that can be used to thread bolts to connect two flanges.


Although flanges can bring us a lot of convenience in our lives and create a tight connection effect, we still need to regularly repair and maintain them during the use of flanges to ensure performance. And do a good job of maintenance, and also pay special attention to corrosion prevention, which is particularly important in order to improve its service life.


The quality of flanges is determined by the environment of large pipelines. Because the environment of large pipelines is very harsh, the quality of flanges must be qualified and of high quality. For flanges, we also need to carry out repairs and maintenance to maintain their performance.


1. Maintain appropriate temperature

The most suitable temperature for flanges is around 80 degrees, which is a general situation and can maintain its performance.


2. Stability of flange packing

Why choose flange packing? Because this can prevent gas leakage or liquid leakage. When choosing filling materials, we need to choose composite agglomerative coating materials, which can provide anti-corrosion and sealing. Especially for high-pressure flanges, this filling material can bring about the effect of saving money, time, and effort.


3. Flange joints should be dustproof and waterproof

When using liquid flange joints, we should pay special attention to factors such as dust and water droplets, as these can affect the material of the flange and whether it is anti-corrosion.


4. Timely inspection and cleaning

As a maintenance technician and engineer for flange tools, it is necessary to regularly check the sealing condition of flange joints and inject fresh lubricating grease into the flange joints to avoid impurities and other substances; If it encounters rust, it should be cleaned in a timely manner. Especially in winter, when the weather is getting colder, it is necessary to conduct all inspections and maintenance on the hydraulic flange joints.
