Quality identification of spiral steel pipes
1. The trademarks and printing of high-quality tubes are relatively standard. 2. The composition of high-quality steel is uniform, the tonnage of the cold shear machine is high, and the end face of the cutting head is smooth and regular. However, due to poor raw materials, the end face of the cut...Read more -
What is an ERW steel pipe
What is an ERW steel pipe? The biggest difference between ERW steel pipe (Electric Resistance Welding, abbreviated as ERW) and seamless steel pipe is that ERW has a weld seam, which is also the key to the quality of ERW steel pipe. Modern ERW steel pipe production technology and equipment, due to...Read more -

Introduction to the construction process of steel pipe piles
The purpose of steel pipe pile construction is to transfer the load of the upper building to the deeper soil layer with a stronger bearing capacity or to compact the weak soil layer to improve the bearing capacity and compactness of the foundation soil. Therefore, the construction of pipe piles m...Read more -
The significance of the oil casing heat treatment process
In addition to being used for oil extraction, the emergence of oil casing can also be used as a pipeline for transporting raw materials. To enhance the quality of oil casing, every link in the production process is particularly important, especially the temperature control during the period, whic...Read more
