ASTM A312 TP347 Steel Pipe 3 Inch:
HT PIPE is the top most producer & wholesaler in ASTM A312 TP347 Steel Pipe 3 Inch, which has slightly improved corrosion resistance over SS 321 in strongly oxidizing environments. SS 347 Seamless Pipe is also advantageous for high temperature service because of its good mechanical properties. SS 347 Tubes offers higher creep and stress rupture properties than SS 304 and, particularly, SS 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns.
ASTM A312 TP347 Steel Pipe 3 Inch is a columbium (niobium) / tantalum stabilized austenitic chromium-nickel stainless steel which was developed to provide an 18-8 type alloy with improved intergranular-corrosion resistance. 347 Stainless Steel Fabricated Pipe has a slightly improved corrosion resistance over other alloys of stainless steel in strongly oxidizing environments as a result of the addition of columbium (niobium) and tantalum. SS Grade 347 Welded Pipe is suitable for the use in many of the applications such as gas processing, petrochemicals industry, power generation industry, heat exchanger pharmaceuticals equipment, pharmaceutical industry, seawater equipment, chemical equipment, and specialty chemical industry.
