How to calculate the yield point of seamless square tube

2022-06-11

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

2022-06-07

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?

2022-06-07

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.
