Precision tube will contact a lot of oil in the production process

Release time: September 27, 2020 popularity: two
    Precision tube In the production process, there will be a large amount of oil, which will lead to a layer of oil on the surface of the pipe after production. Before delivery to the customer, it is necessary to clean the precision pipe once, because the cleaned precision pipe can be used directly by customers, so there is no need to worry about the oil pollution on the surface.

       Do you know the specific steps of oil removal of precision pipe, and what details should we pay attention to in the process of oil removal. If you are not very clear about these, let's listen to Shandong Qianqian Steel Pipe Co., Ltd.


1. Pickling

Generally, chemical cleaning and electrolysis are used for pickling. The pipeline corrosion protection is only used for chemical pickling. It can remove oxide scale, rust, old coating, and sometimes can be used for sand blasting. Although chemical cleaning can achieve a certain degree of cleanliness and roughness, its anchoring pattern is shallow and easy to pollute the environment.

2. Cleaning

Clean the surface of No.20 precision pipe with solvent and emulsion to remove oil, grease, dust, lubricant and similar organic matter, but it can not remove rust, oxide and flux on the surface of 20 precision pipe, so it is only used as auxiliary material in anti-corrosion production. Means.

3. Tool rust removal

Steel wire brush and other tools are mainly used to polish the surface of No. 20 precision pipe to remove loose or protruding oxide scale, rust and welding slag. The derusting ability of manual tools can reach SA2, while that of electric tools can reach SA3. If the surface of No.20 precision pipe adheres to the iron oxide scale, the rust removal effect of the tool will not be ideal, and the anchorage depth required by the corrosion protection structure will not be achieved.

4. Spray (throw) rust removal

Spraying (polishing) and derusting are carried out by high-power motor to drive the spraying (throwing) blade to rotate at high speed, so as to spray (throw) steel sand, steel shot, line segment, mineral and other abrasives to the surface of No. 20 precision pipe under centrifugal force. This treatment not only can completely remove rust, oxide and dirt, but also can achieve the required uniform roughness under strong abrasive impact and friction.
