As a common decoration construction material in our modern life, galvanized square tubes can be said to be widely used.

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.

On September 6, the China Enterprise Confederation and the China Entrepreneurs Association (hereinafter referred to as the China Enterprise Confederation) held a press conference in Beijing and released the list of the "top 500 Chinese manufacturing enterprises in 2022".

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

In the steel pipe industry market under the premise of low, many steel pipe enterprises use the Internet, seize the opportunity of network marketing, to achieve the company against the trend of growth.

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.

Most of the square pipes are steel pipes, and the hot-dip galvanized square pipes are coated with a layer of zinc on the surface of the steel pipes by a special process. Next, we will explain in detail how to solve the corrosion problem of the galvanized square pipes.

After the square tube is heated, a layer of black oxide skin will appear, which will affect the appearance. Next, we will explain in detail how to remove the oxide skin on the large-diameter square tube.

The outer diameter accuracy of thick walled square rectangular pipe is determined by human, and the result depends on the customer. It depends on the customer's requirements for the outer diameter of seamless pipe, the operation and accuracy of steel pipe sizing equipment, and the steel pipe sizing process system.

By using thinner and stronger structural and cold forming steels like high-strength, advanced high-strength and ultra-high-strength steels, you can save on production costs thanks to easy bendability, cold-forming properties and surface treatment. Additional savings in welding work and filler materials can also be achieved when material thickness is minimized.

The wait-and-see mood of the large-diameter square tube spot market has increased, while the enthusiasm of site procurement has not improved. The shipments of large-diameter square tube spot merchants are less than expected. Under the pressure of capital and shipment, the reduction of shipment this week has become the main tone. However, considering the high cost and low inventory, the willingness of the merchants to sell is not strong, and the correction range is temporarily limited.

It is inevitable that the surface of the rectangular tube will be coated with oil, which will affect the quality of rust removal and phosphating. Next, we will explain the method of oil removal on the surface of the rectangular tube below.

Galvanized square pipe has good performance, and the demand for galvanized square pipe is very large, so how to straighten the galvanized square pipe? Next, let's explain it in detail.

The production process of square tubes is simple, the production efficiency is high, the varieties and specifications are various, and the materials are different. Next, we will explain the essential differences between welded square tubes and seamless square tubes in detail.
