Brief: We tested it—see the highlights and what to expect in real operation. This video provides a detailed walkthrough of the ASME SB336 U-Bending Carbon Steel Pipe, showcasing its manufacturing process, quality control tests, and application in boiler finned tube systems. You'll see demonstrations of precision bending, stress relief annealing, and hydrostatic testing to understand its performance in heat exchange applications.
Related Product Features:
  • Manufactured to ASME SB336 standard with UNS designations including N08926, S31803, and various nickel alloys.
  • Designed as U-bending tubes for boiler finned tubes and heat exchangers with a 20mm diameter.
  • Available in various materials including carbon steel, stainless steel, alloy steel, duplex steel, and copper nickel alloys.
  • Features precision bending capabilities with developed lengths up to 105 feet (32 meters).
  • Undergoes comprehensive quality testing including eddy current, hydrostatic, and dimensional checks.
  • Includes electric resistance stress relief annealing after bending for enhanced durability.
  • Supports multiple OD sizes from 15.8mm to 38.1mm with strict radius and straightness tolerances.
  • Comes with Mill Test Certificate as per EN 10204/3.1 and standard export carton packing.
Pytania:
