In the case of Q235B steel pipe without internal welding ribs, it is easy to cause the problem of not tightly bonding the wear plate and Q235B steel pipe. If the pores are too large, the Q235B steel pipe will shrink.

The element S in steel is the main source of sulfide inclusions, which is easy to produce red hot brittleness; element P mainly affects the temper brittleness and hot brittleness of P91 steel pipe. Therefore, the mass fraction of S and P in steel should b

P91 steel pipe is equivalent to the national standard 10Cr9Mo1VNbN, not only has high oxidation resistance and high temperature steam corrosion resistance, P91 steel pipe also has good impact toughness and high and stable durable plasticity and thermal st

SA 210C steel pipe is an ASME standard steel grade. It belongs to the category of medium carbon manganese steel pipes for boilers, superheaters and pipelines. It belongs to pearlitic heat-strength steel; therefore, SA 210C steel pipe is not stainless stee
