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.

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.

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.

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.

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 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.

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.

Most square pipes are made of steel tubes, and hot dip galvanized square pipes are made of a special process to attach a layer of zinc to the surface of the steel tubes. Next, we will explain how to solve the corrosion problem of galvanized square pipes in detail.

The main component of the galvanized square tube is zinc, which is easy to react with the oxygen in the air. What will the color of the galvanized square tube turn white? Next, let's explain it in detail.

1. Sign the company contract, indicating the detailed information and parameters of the purchased products, and stamping the company seal.
2. Transfer the money to the company's bank account on the contract, and ensure that it is the company's account.
Three, to ensure quality and material and quantity, large quantity must be inspected on the spot.

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

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".

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

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

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.

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.

Notice! Notice! Tianjin Yuantai Derun Steel Pipe Manufacturing Group will participate in the 132nd Canton Fair from October 15 to October 24, 2022

Square tube is a kind of material commonly used in the industrial construction industry, with a large demand. There are many square tube products on the market, and the quality is uneven. Attention should be paid to the selection method when selecting:

According to the "2022 RMB Internationalization Report" released by the People's Bank of China, the share of RMB international payments will increase to 2.7% in December 2021, surpassing the Japanese yen to become the fourth payment currency in the world, and will further increase to 3.2% in January 2022. a record high.

JCOE is a pipe making technology for the production of large diameter thick wall steel pipes. It mainly adopts the production process of double-sided submerged arc welding. The products go through multiple processes such as milling, pre bending, bending, seam closing, internal welding, external welding, straightening, and flat end.

Tianjin Yuantai Derun Group has embarked on the road of green development

Tianjin Yuantaiderun Group, as a national high-tech enterprise and a leading enterprise in China's rectangular tube industry, is a large joint enterprise group focusing on the production of black and galvanized rectangular tubes, taking into account logistics, trade, etc.

Through the successful project practice of 2017 Egypt project structure hot-dip galvanized square pipe and 2019 Qinghai project structure hot-dip galvanized round pipe, Tianjin Yuantai Derun Group has demonstrated its service ability in domestic and foreign major projects

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:
