steel pipe knowledge

Sharp angle square tubes are very common in practical applications, and there are many different types of sharp angle square tubes to choose from. Therefore, when selecting the sharp angle square tube, it is necessary to select the appropriate sharp angle square tube according to the actual application.

The production process of straight seam steel pipe is relatively simple. The main production processes are high-frequency welded straight seam steel pipe and submerged arc welded straight seam steel pipe. Straight seam steel pipe has high production efficiency, low cost and rapid development.

The strength of spiral steel pipe is usually higher than that of straight seam steel pipe. The main production process is submerged arc welding.

The square tube market is a mixture of good and bad, and the quality of square tube products is also very different. In order to let customers pay attention to the difference, today we summarize the following methods to identify the quality of square tube products.

The quality control of yuantai steel pipe is very strict, so customers can choose with confidence.Yuantai company Obtained 77 patents，Yuantai steel has won the single champion of rectangular tube industry for 10 consecutive years,

During the production of square and rectangular tubes, the feeding accuracy directly affects the accuracy and quality of the formed products. Today we will introduce seven factors that affect the feeding accuracy of rectangular tube:

Seamless square and rectangular tubes have good strength, toughness, plasticity, welding, and other technological properties, and good ductility. Its alloy layer is firmly attached to the steel base.

Hot dip galvanized steel pipe, also known as hot dip galvanized pipe, is a kind of steel pipe that is galvanized to improve its service performance. Based on the principle of combination and wide application, it is determined that the alloy layer is produced by the reaction of the substrate, thus combining the substrate with the coating. How are hot-dip galvanized steel pipes processed? The process flow of hot-dip galvanized steel pipe is divided into the following steps:

Square tube is a kind of material widely used in industrial construction industry, which is in great demand. There are many square tube products on the market, and the quality is uneven. Pay attention to the selection method when selecting:

In order to improve the surface hardness and wear resistance of 16Mn rectangular tubes, surface treatment, such as surface flame, high-frequency surface quenching, chemical heat treatment, etc.

The longitudinal submerged arc welding pipe is produced by rolling the steel plate into a cylindrical shape and connecting the two ends together through linear welding.

At present, 16Mn seamless square pipe technology has been extremely mature, and there are corresponding product standards and various types of application technologies.

The production process of high-frequency welded pipe mainly depends on the variety of products.

In the prior art, a two-step method is used to connect q355b rectangular tubes.

The main component of the galvanized square pipe is zinc, which is easy to react with the oxygen in the air, so what will the color of the galvanized square pipe turn white? Next, we will explain it to you in detail.
