PRE-INSULATED TUBES

PRE-INSULATED TUBES

Definition

  1. Definition of Pre-insulated Tube
    1. All-in-one typed thermal insulated tubing bundle which means welding and field insulation works are not required on construction site.
    2. It is used for maintain pipe line’s temperature, instrument sensing line.
  2. Applications
    1. Steam supply & Condensate return line.
    2. Instrument hook-up line.
    3. Analyzer sampling line (Including TMS sampling line).
    4. Utility line, etc.

USING CARBON STEEL PIPE AND INSULATION

Conventional steam tracing system

Advantages

  1. Saving over 30% of piping installation cost comparing to conventional method.
    1. Conventional method of steam tracing system using piping & field Insulation

2. Pre-Insulation tube method

  1. Reducing Energy Loss.
    1. Conventional Steam Manifold (Using perlite Insulation)

    2. PIT Steam Manifold

  2. Securing Operation stability by reducing failure rate of Steam trap.
    1. Compare to conventional steam tracing system using carbon steel pipe previously used, PIT reduces the failure rate of steam trap dramatically during the operation by its inner scale reduction.
      1. Conventional steam tracing system using carbon steel pipe
        1. NCC Plant : 5.8 % (Steam trap : 4,225 EA)
        2. BD/BTX Plant : 3.4 % (Steam trap : 1,480 EA)
        3. Tankage/Utility : 6.3 % (Steam trap : 1,662 EA)
      2. Steam tracing system using Pre-insulated tube
        1. Phenol/BPA : 1.8 % (Steam trap : 1,783 EA)
  3. Anti-chloride Coated Metal Tube for Protecting Chloride Stress Corrosion Cracking (CSCC)
  4. Reduction of Construction period & Maintenance quality improvement.
  5. Easy to move from piping interference during the maintenance work.
  6. Provides Clean operation environment.
