Cutting machine for Heat Exchanger Tubes

Product catalog summary
Overview: The document describes a cutting machine used in the manufacturing process of heat exchangers, specifically for trimming tubes to a precise length as they pass through the tube sheet.
Technical Specifications:
  • Standard Capacity: 59.05" - 118.11" (1500mm - 3000mm)
  • Outer Diameter (O.D.) of Pipe: 0.472" - 0.984" (12-25mm)
  • Pipe Wall Thickness: 0.019" - 0.078" (0.5-2mm)
  • Width of Tube-plate (A): 7.874" - 15.748" (200-400mm)
  • Length of Fixed Legs (B): 9.842" - 17.716" (250-450mm)
  • Diameter of Tube-plate (C): 43.307" - 129.921" (1100-3300mm)
  • Distance Between Pipe Centers (D): 0.629" - 1.141" (16-29mm)
  • Pipe Material: 304, 316, 321 stainless steel
  • Diameter of Raised Part on Tube-plate (E): ≥ 15.748" (400mm)
  • Height of Raised Part on Tube-plate (F): 0.393" - 0.59" (10-15mm)
  • Height of Pipe Before Cutting: ≤ 15.748" (400mm)
  • Height of Pipe After Cutting: ≤ 0.197" (5mm)
Machine Features:
  • The machine is based on the XP machine frame but lacks a machining head.
  • It employs two milling heads with saw blades for cutting.
  • The arms with milling heads rotate 180° to cut all tubes on the same tube sheet.
  • Post-cutting, a PROTEM SM8 is used for precise tube facing.
  • Manual cutting previously took over 3 days, whereas the machine reduces this to less than 1 day.
Operational Details:
  • The machine is used when tubes are not the same length out of the tube sheet, trimming them to 0.197" (5mm) from the tube sheet.
  • Tubes are not clamped on the tube sheet, maintaining a small gap of 0.0039" (0.1 mm).

Cutting machine for Heat Exchanger Tubes-1

THE FUTURE OF ON SITE MACHINING Cutting Machine for Heat Exchanger Tubes Standard Capacity: 59.05" - 118.11" (1500mm - 3000mm) The machine is used during the heat exchanger manufacturing process when they pass the tubes across the tube sheet. The tubes that are not the same length out of the tube sheet will be cut to 0.197" (5mm) from the tube sheet. The tubes are not clamped on the tube sheet, there is a small gap of 0.0039" (0.1 mm). The machine is based on a frame of XP machine but without a machining head. It uses two milling heads with saw blades. The arms with milling heads perform the cut of all the tubes on the same tube sheet with a 180° rotation. After the cut, a PROTEM SM8 is used to face the tubes precisely. By hand (with a grinder), they needed more than 3 days to make all the cuts and now, with the machine, less than 1 day is enough.
