What Are The Cleaning Methods For Pipe Bending? What Are The Causes Of Wrinkles in Pipe Bending

In the process of elbow processing, the treatment of its appearance is very key, because it will directly affect the service life of its products. The different types of coatings used for elbow surface treatment and the quality of coating will directly affect the future use of products.

During the cleaning process, the surface of the elbow needs to be cleaned with its emulsion or solvent, which can effectively remove the dust and grease on the steel, as well as the smoothing agent and organic matter.

The above cleaning method can not effectively remove the rust, oxide scale and welding flux on the steel pipe surface. It is necessary to polish the steel surface with its steel wire brush, so as to effectively remove the rust, welding slag and other impurities on the material surface.

At the end of the bend, one-step cleaning needs pickling, which is often referred to as chemical cleaning. Such cleaning is mainly aimed at the anti-corrosion performance of the product and can effectively remove its oxide skin and old coating. However, chemical cleaning will easily form its pollution. Generally, it can be effectively made into sand blasting for rust removal.

The volume of elbow used in cleaning must be able to effectively remove grease, dust and other substances on the product surface, and remove oxide skin and rust on the steel surface, so cleaning can play an auxiliary role.

Bends often encounter many problems in the production process. After the product is produced, it will be found that there is a fold in the middle part. If such a situation occurs, it means that such a product is unqualified, because the fold is easy to be impacted by pressure after the elbow is installed, allowing the elbow to leak and deform.
