Seamless pipe without quenching hardness less than HRC28, relatively soft, not wear-resistant; quenched hardness can be (note that it can be) greater than HRC55, wear resistance is better, but this is a small cross-section, the cross-section is slightly larger, the hardness obtained will be reduced.
Read moreIn the construction of pile foundations, concrete square piles and pipe piles are involved, and these two types of piles are different from each other in terms of appearance and characteristics.
Read moreThe quality of cs seamless pipe billet requirements with the perforation process is closely linked. The selection of a reasonable perforation, change the unfavorable stress state, can prevent defects, but also to reduce the requirements of seamless steel pipe billet.
Read moreWrong side is the most common problem in the pre-welding of straight seam welded pipe, and the wrong side is out of tolerance, which directly leads to the degradation or scrapping of the steel pipe.
Read moreThermal expansion seamless is a processing method of steel pipes, which is to process small-diameter seamless pipes into large-diameter seamless pipes.
Read moreThere are three main deformation processes in the production of seamless steel pipes today: perforation, pipe rolling and diameter reduction.
