The 34CrMo4 seamless steel pipe for high pressure gas cylinder produced by Katalor. Our 34CrMo4 seamless steel pipe has the advantages of smooth inner and outer wall, uniform wall thickness, light weight, high yield and low cost, etc., and 34CrMo4 seamless steel pipe is popular with customers.
According to the market demand, the seamless steel pipe for high pressure cylinder of medium carbon Cr, Mo series has been developed one after another. Among them, 34CrMo4 seamless steel pipe is a high-end product in GB/T18248-2008 gas cylinder seamless steel pipe.
Oxidative decarbonization occurs at the defect, and a large number of fine high temperature oxide particles are dispersed on the side and tip of the defect.
It is shown that there are internal cracks in the billet before entering the 34CrMo4 seamless steel pipe annular heating furnace, and the high temperature oxidation decarburization reaction occurs between the billet and the cracks connected to the atmosphere during the 34CrMo4 seamless steel pipe heating process, which can not “heal” and form a “internal bubble” defect during the subsequent rolling deformation.
According to the above analysis of 34CrMo4 seamless steel pipe inner wall defects, it is the key to prohibit the local heating of 34CrMo4 seamless steel pipe billet in the production plant. In order to improve the efficiency of perforation, the end of 34CrMo4 seamless steel pipe billet can be perforated by machining method.
