Product Information

Paper Industry Pipes


Our paper industry stainless steel pipes are professionally customized for the unique working conditions of papermaking and pulp production processes. The papermaking industry involves medium corrosion, high humidity and long-term continuous operation scenarios. Our pipes feature excellent acid and alkali corrosion resistance, smooth inner wall, no scaling, clean and hygienic performance, as well as stable mechanical properties. They effectively adapt to pulp transportation, wastewater treatment, process water circulation and heat exchange systems in paper mills, ensuring pollution-free material transmission, low operation resistance and long service life, which perfectly meets the high-standard clean production and stable operation requirements of the modern paper industry.


Main Material Grades

We provide dedicated stainless steel material grades for paper mill production, covering conventional austenitic stainless steel and high-performance duplex stainless steel to suit different process and corrosion resistance demands:
  • TP304, TP304L

  • TP316, TP316L

  • TP321

  • UNS S31803 (S32205)

  • 08X18H10T / 12X18H11T /12X18H10T / 10X23H18


Manufacturing Standards

All paper industry pipes are manufactured and tested in strict accordance with authoritative Chinese, American and Japanese industrial standards, with stable quality and strong applicability, fully compliant with papermaking process fluid transmission and piping engineering specifications:
  • GB/T 14976-2002: Seamless Stainless Steel Pipes for Fluid Transportation

  • GB/T 12771-2000: Welded Stainless Steel Pipes for Fluid Transportation

  • ASTM A312: Seamless and Welded Austenitic Stainless Steel Pipes for High-temperature Service

  • ASTM A789: Seamless and Welded Ferritic-Austenitic Stainless Steel Tubes for General Service

  • JIS G3448: Stainless Steel Pipes for Ordinary Piping Service
