ASTM A789 Bright Annealing Duplex Steel For Industrial Tubing
The advantages of duplex construction are resistant to stress corrosion cracking and high strength and ease of fabrication and corrosion resistance.
The stainless steel tubing is generally produced by a cold-drawing process. A subsequent annealing process is required to eliminate residue stress and obtain improved softness and ductility.
Industrial Tubing Application
a) Petroleum
b) Chemical industry
c) Instrument
d) Industrial transportation
e) Mechanical structure industry
f) Need high corrosion ability pipe's industry, such as the offshore industry, etc
Industrial Tubing Advantages
a) Superior surface finish,
b) Better mechanical property
c) More precise dimension
d) Perfect inspection method and inspection equipment
