Black annealed pipes actually belong to a very common and widely used steel pipe. If cold-rolled steel is heated to an annealed temperature, the appearance of cold-rolled steel is black due to high temperature contact with air, and its appearance is not brightened. The physical properties will become soft, which is conducive to further welding into steel pipes. It can be retreated to different hardness as required.
The black pipe manufacturer uses a new type of profile with very high stability function when it is produced, so the product produced by the manufacturer has a very good stability function at the time of use, no matter how harsh the environment is to use this product. Customers can use it with confidence that there will be no quality problems.
The black retreat pipe is more comprehensive than the previous black retreat strip steel. In the process of use, this product not only has a good anti-corrosion function, but also allows the black retreat pipe to be normal no matter what kind of harsh environment. The application of this product will not cause any quality problems, and this product has a good fire protection function when it is used.
The black drawn pipe is a relatively common type of steel pipe, and it is a kind of steel pipe with thin annealing density. It has softer physical properties and can achieve the effect of no cracking and no opening. The black pipe is made of A3 material through a series of functions, in order to prevent some rust. Mainly used for bicycles, tricycles and all lightweight vehicles.
