The steel expansion joint is an elastic element that can effectively compensate the axial displacement. As a common device for pipe fittings, it mainly compensates for pipe deformation caused by thermal factors. In addition, steel expansion joints are widely used in real life. However, the service life of steel expansion joints is also affected by many factors, and daily maintenance and cleaning can effectively reduce their damage. In this article, I will explain to you five ways to clean steel expansion joints.

During the manufacturing and assembly process, the steel expansion joints are prone to rust and the surface is also prone to sand and dust. This type of impurities can greatly affect the normal use of steel expansion joints. Therefore, proper cleaning and repair will help to extend the service life of steel expansion joints.

The five ways to clean steel expansion joints are summarized as follows:

1. Chemical cleaning

It is necessary to use a chemical cleaning method when cleaning steel expansion joints. In addition, cleaning steel joints from both sides with temporary piping and circulating pumping stations is a good method. Chemical cleaning has many advantages, such as convenience, speed, and the like. In addition, chemical cleaning has no special requirements for the shape of steel expansion joints.

2. PIG cleaning

It relies on the pump to drive the fluid so that the PIG moves forward within the pipe and eliminates dirt inside the pipe. PIG cleaning method is widely used in various process pipelines, oilfield pipeline cleaning, especially for long-distance pipeline cleaning.

3. High pressure cleaning

It is recommended to use a high temperature water jet of 50 Mpa or more to clean the pipe. In addition, it is suitable for short pipe systems with a diameter of more than 500 mm. It has the advantages of high speed and low cost.

4. Manual derusting

First, you can apply a hammer tap or a wire brush and a waste wheel to handle rust, coarse rust and weld slag. Then you can use scales, wire cloth, and rough rags to treat scales, rust and other scales. Finally, you can clean with a clean cloth or cotton yarn. To derust the inner surface of the tube, you can also use a round wire brush and the ropes are bundled back and forth at both ends to check the metallic luster.

5. Mechanical rust removal

We can also use rust removal equipment such as electric grinding wheel, pneumatic brush, electric rotating wire brush, electric descaling machine and so on.
