Summary

In the increasingly fierce and cruel competition in the domestic and international low-alloy steel pipe market, we must persist in continuously innovating management and technology to overcome new challenges and achieve better and faster development.

  In the increasingly fierce and cruel competition in the domestic and international low-alloy steel pipe market, we must persist in continuously innovating management and technology to overcome new challenges and achieve better and faster development.

 

  During the 12th Five-Year Plan period, we should also have more awareness of potential risks. I have two suggestions: First, I suggest that the state should advocate the use of more steel structure buildings in construction projects. This is conducive to energy saving, emission reduction, and the recycling of 20G steel pipe resources, achieving sustainable development.

 

  We must pay attention to and resolve these imbalances, focusing on solving problems such as overcapacity of 15crmog alloy steel pipes caused by repeated construction, and ensuring the sustained, healthy, and stable development of the national economy.

 

  In addition, during the 12th Five-Year Plan period, the steel industry has many things to do, such as increasing the development of 12cr1movg alloy steel pipe raw materials. First, we must make good use of domestic mineral resources, strengthen work in all aspects, seek more support, and enable domestic mines to be scientifically and environmentally friendly mined.

 

  Currently, there is some waste in domestic mining, and it has also caused some environmental impact. This situation should be changed as soon as possible. It should be particularly pointed out that it is very difficult to "go global" and control resources now, and 16mn seamless steel pipe enterprises should have a full understanding of this.

 

  Facing the new opportunities during the 12th Five-Year Plan period, the 45# seamless steel pipe steel industry should adhere to accelerating the transformation of the economic development model as the main line, and follow the path of scientific development by continuously adjusting the industrial structure and product structure.

How to calculate the yield point of seamless square tube


For metallic materials exhibiting yield phenomenon, the stress at which the specimen continues to elongate without any increase in force (the force remains constant) during tensile testing is called the yield point. If the force decreases, the upper and lower yield points should be distinguished. The unit of yield point is N/mm2 (MPa).

Seamless steel pipe performance, use and types


A crucial aspect of the quality of precision welded tubes is the removal of burrs from inside the weld seam. Due to spatial constraints, the removal of internal burrs in small-diameter welded tubes has always been a technical challenge in the welded tube manufacturing industry. Therefore, selecting a suitable welding method from the welding technology aspect is an effective way to solve the problem. Welding methods that produce welds with small internal burrs include direct current welding and square wave resistance welding. These welding methods are characterized by uniform heating, smooth weld seams, good quality, and the formation of very small internal burrs, generally only 0.1~0.2㎜.

How to identify thick-walled seamless steel pipes?


In the actual trading environment, the quality of Jiangsu seamless steel pipes is uneven, and there are many counterfeit and inferior products. So how to identify thick-walled seamless steel pipes? The following is an introduction: Counterfeit Jiangsu seamless steel pipes often have rough surfaces. The uneven surface refers to the irregular raised defects on the surface of Jiangsu seamless steel pipes caused by serious groove wear. This is because Jiangsu seamless steel pipe manufacturers excessively pursue profits, and the rolling groove process has not been replaced. Counterfeit and inferior Jiangsu seamless steel pipes are prone to scarring on the surface There are two reasons for this: on the one hand, the quality of Jiangsu seamless steel pipes is uneven, and there are more impurities; on the other hand, the manufacturer's guide device is not good, it is easy to stick steel, and impurities are easy to leave scars on the surface of the stainless steel pipe after rolling. Counterfeit wood surfaces are prone to cracking The reason for cracking is that the billet is an earth billet, and the earth billet has larger pores. The earth billet is easily cracked under the influence of thermal stress during cooling, causing cracks in the stainless steel pipe after rolling.
