Heat Exchanger Tube Cleaning & Hard Scale Removal Service in Bangladesh

Professional Heat Exchanger Cleaning by Chemical Circulation & Tube Cleaning Machine

Heat exchangers are one of the most critical components in industrial plants. Over time, hard mineral deposits, corrosion products, and process contaminants accumulate inside the tubes, significantly reducing heat transfer efficiency, increasing energy consumption, and causing unexpected equipment failures.

At Classic Industrial Service BD, we provide professional Heat Exchanger Cleaning Services using advanced chemical recirculation systems combined with mechanical tube cleaning machines. Our experienced engineers select the most suitable cleaning method according to the tube material, scale composition, and operating conditions to restore maximum heat transfer efficiency without damaging the equipment.

Types of Heat Exchanger Tubes We Clean

Our cleaning services are suitable for various tube materials, including:

  • Copper Tubes
  • Stainless Steel (SS316) Tubes
  • Titanium Tubes

We can clean almost all common tube sizes, including:

  • 12 mm Tube Diameter
  • 15 mm Tube Diameter
  • 18 mm Tube Diameter
  • 23 mm Tube Diameter
  • 25 mm Tube Diameter

Tube lengths commonly serviced include:

  • 3 Meter
  • 5 Meter
  • 8 Meter
  • Other custom lengths

Common Hard Scale Deposits Removed

Industrial cooling water, boiler water, seawater, and process fluids gradually form hard deposits inside heat exchanger tubes. These deposits reduce water flow and create thermal insulation, causing serious efficiency losses.

We successfully remove various types of hard scales, including:

  • Calcium Carbonate (CaCO₃)
  • Magnesium Scale
  • Iron Oxide Deposits
  • Calcium Sulphate
  • Silica Scale
  • Rust Deposits
  • Corrosion Products
  • Biological Fouling
  • Sludge and Mud Deposits

Even heavily blocked tubes can often be restored through a combination of chemical descaling and mechanical cleaning.

Chemical Cleaning Methods

Selecting the correct cleaning chemical is essential to remove scale safely without damaging the tube material. Our engineers evaluate the scale type before selecting the appropriate chemical.

HCl Based Chemical Cleaning

Hydrochloric Acid (HCl) based chemicals are highly effective for removing:

  • Calcium Carbonate
  • Rust
  • Iron Oxide
  • Heavy Mineral Deposits

Suitable inhibitors are added to protect metal surfaces during cleaning.

Sulphamic Acid Based Cleaning

Sulphamic Acid provides controlled descaling for sensitive equipment and is commonly used for:

  • Medium Hard Scale
  • Carbonate Deposits
  • Mild Corrosion Products

It offers excellent cleaning performance with lower corrosion risk compared to stronger mineral acids.

Phosphoric Acid Based Cleaning

Phosphoric Acid is widely used where surface protection is important. It effectively removes:

  • Rust
  • Iron Oxide
  • Light Scale
  • Corrosion Products

It also helps passivate metal surfaces after cleaning.

Alkaline Chemical Cleaning

Alkaline cleaners are used for removing:

  • Oil
  • Grease
  • Organic Fouling
  • Biological Slime
  • Process Contamination

These cleaners are often used before acid cleaning to improve overall descaling efficiency.

Mechanical Tube Cleaning

For extremely hard deposits, chemical cleaning alone may not be sufficient.

We utilize professional tube cleaning machines equipped with flexible shafts, nylon brushes, stainless steel brushes, carbide tools, and rotating cleaning heads to remove stubborn scale mechanically.

  • Mechanical tube cleaning provides by Special Tube cleaning Machine
  • Special case Cleaning by water hydeo-Jet Machine.
  • Complete removal of hard deposits
  • Improved water flow
  • Restored heat transfer performance
  • Longer equipment life
  • Reduced pressure drop

The cleaning tools are selected according to the tube diameter and material to avoid internal damage.

Combined Chemical Recirculation & Mechanical Cleaning

The most effective cleaning process often combines chemical circulation with mechanical tube cleaning.

Our standard procedure includes:

  • Equipment inspection
  • Scale identification
  • Selection of appropriate cleaning chemical
  • Closed-loop chemical recirculation
  • Neutralization and flushing
  • Mechanical tube brushing
  • Cleaning by water Jet Machine
  • Final flushing
  • Performance verification

This combined approach removes both soft deposits and extremely hard mineral scales while minimizing downtime.
