In the process of smelting or hot working steel, due to certain factors (such as non-metallic inclusions, gases, and improper process selection or operation, etc.). Resulting in defects in the interior or surface of the seamless tube, which will seriously affect the quality of materials or products, and sometimes lead to scrapping of materials or products. Looseness, bubbles, shrinkage…
Read MoreBurs are ubiquitous in the metalworking process. No matter how advanced and sophisticated equipment you use, it will be born with the product. This is mainly due to the plastic deformation of the material and the generation of excessive iron filings at the edges of the processed material, especially for materials with good ductility or toughness, which are particularly…
Read MoreThe bright heat treatment of seamless tubes does not have to be a vacuum furnace. It is heated in a protective atmosphere, which is what we often call a continuous bright quenching furnace. The protective gas is pure hydrogen or a mixture of nitrogen and hydrogen, which can also decompose ammonia into gas. There is another kind, quenching in…
Read MoreWhen the carbon steel tube is in use, the oxide film on the surface is not easy to fall off. Usually, oxide films are produced in a heating furnace. So, how to clean the oxide film on the surface of the carbon seamless steel tube? 1. Iron oxide scale cleaning machine treatment The scale cleaning machine is mainly composed…
Read MoreThe general application of thick-walled seamless tubes must do the corresponding anti-corrosion and anti-rust treatment work. The general anti-corrosion work is divided into three processes: 1. Anti-rust treatment of pipes. Before painting, the surface of the pipeline should be cleaned of oil, slag, rust, and zinc dust. The product quality standard is Sa2.5. 2. After the anti-rust treatment on…
Read MoreLow carbon steel is a type of carbon steel. Carbon is present in all steels, and as long as carbon is the predominant alloying element in this steel, the alloy is considered carbon steel. “Low carbon” steel is another name for low carbon steel, and there are other carbon steels with different carbon contents. Which one is better depends…
Read MoreThe billet used in the production of steel pipes is called tube billet. Usually high-quality (or alloy) solid round steel is used as the tube billet. According to different production methods, carbon steel seamless tubes have billets made of steel ingots, continuous casting billets, forging billets, rolled billets and centrifugally cast hollow billets.Since the quality of the tube billet…
Read MorePrecautions for seamless tube production: 1. Pay attention to whether the thickness of the capillary wall is uniform. If it is found that the thickness of the capillary wall is uneven, the surface polishing treatment must be performed. In addition, whether the inside and outside of the capillary tube is flat and there are no bumps and defects. Once…
