Burs 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 MoreProduction of oil or gas is a complex, time- and cost-intensive undertaking, but in principle, every wellbore goes through three phases: Drilling with drill pipes, lining with casing pipe and production with tubing. 1. Drilling with drill pipes Drill pipes are durable steel pipes that conduct the force to the drill bit. In many cases the drill pipe turns…
Read MoreCold rolling refers to the processing of steel plates or strips into various types of steel through cold working such as cold drawing, cold bending, and cold drawing at room temperature. Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Carbon steel pipes are made of steel ingots or solid billets through perforation into…
Read MoreWelding problems are sometimes encountered during the installation of carbon steel tubes. So, how to weld tubes? What should we pay attention to when welding carbon steel tubes? 1. Gas welding Gas welding can be used for welding, which is to mix combustible gas and combustion-supporting gas together, use it as the heat source of the flame, and then…
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…
