All-round structural steel pipe manufacturer-Tianjin Yuantai Derun Steel Pipe Manufacturing Group

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.

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.

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:

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

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.

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.

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.

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.
