The necessity of pickling seamless pipes
What is pickling: The method of removing scale and rust on the surface of steel with an acid solution is called pickling. Pickling acids include sulfuric acid, hydrochloric acid, phosphoric acid and mixed acids. The pickling process is to remove the oxide scale on the surface, and then lubricate ...Read more -
The introduction of carbon seamless pipe
Carbon seamless tube is a kind of long bar. The pipe has a hollow cross-section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid materials such as circles, pipes have the same...Read more -
Environmental requirements for storage of seamless pipes
1) The site or warehouse where the seamless pipes are kept should be selected in a clean and well-drained place, away from factories and mines that produce harmful gases or dust. Remove weeds and all debris on the site and keep the steel clean; 2) Do not store acid, alkali, salt, cement and other...Read more -
