Duplex stainless steel pipe
2205,2507 Seamless Duplex Stainless steel pipe
Seamless Duplex Stainless steel pipe are with high mechanical
strength, good elongation and weld ability which needs no
pre-heating before welding and heat treatment after welding, low
thermal expansion, excellent resistance to stress corrosion
cracking, pitting and crevice corrosion, and high resistance to
general corrosion in different environments. Duplex stainless steel
tubes & pipes are applied to heat exchangers in refinery
industries, petrochemical plants, paper & pulp industries,
sugar & beverage industries.
