Seamless steel pipe repair and maintenance

In addition to stainless seamless steel Method: steel refers to iron as the main element, the carbon content is generally 2.0% or less and containing a metal element other materials. It is the difference between the iron content of the element carbon, it should be said that he is more tough and durable than iron, although not easy to rust, but there is no guarantee will be eroded, if once eroded, if not promptly treated, it is easy to be eroded away, it should have lost its original function. When rusted seamless steel pipe, the usual treatment methods, what does? Some people will use clean way of stainless steel pipe cleaning, cleaning, you should use a solvent, emulsion clean the surface of steel, this method only as a secondary means of corrosion, can not really play to remove the stainless steel pipe rust effect. We can also steel brush before cleaning, wire balls and other tools will loose oxide surface, remove rust, but this way if protective measures or do not do, then he will once again be eroded. Pickling is one method of removing rust. General chemical and electrolytic pickling are two ways to do, pipeline corrosion using only chemical pickling, although this method can achieve a certain degree of cleanliness but easy to pollute the environment, so it is not recommended for use. A jet blasting, high-power motor driven by high-speed rotating blade jet so that grit, steel shot, wire segments, minerals and other abrasive under the centrifugal force on the surface of stainless steel pipe blasting treatment. Not only completely remove rust, oxides and dirt, and steel pipe under the influence of severe abrasive impact and friction force, but also to achieve the required uniform roughness. Spray rust corrosion pipeline ideal method of blasting method. Which use a lot of theoretical physics, to environmental pollution small and clean thoroughly.
Seamless steel pipe maintenance: seamless knowledge to understand a lot of people have is more and more, but a lot of people only know the seamless steel pipe production, sale and use of knowledge, etc., but some of it is very important, that is, maintenance and repair! making seamless steel pipe seamless steel pipe manufacturing time, will involve the pickling process of steel pipe. For the staff, the seamless steel pickling during the time what issues need attention too.
First, before pickling must wear a good labor protection. For field work environment should be a detailed examination, mainly to check the pipe tape is intact, the job can be carried out after confirmation well. Second time in pickling, pickling is mainly used hydrochloric acid, hydrochloric acid content is generally 18% to 20% of the best. The third staff member at the front also requires the acid concentration and temperature of the tank and pipe pickling tonnage understood. These can be detected by using a specialized measuring equipment. For the pickling of steel every fourth best in the weight control between 2-5 tons, the time to grasp in 5-15 minutes. The time required based on how much weight can be adjusted. Steel pickling process sub-ah also need regular vibration, in an acid tank to the pipe when the pipe to be inclined to prevent accidental injury to people hydrochloric acid.
