Tube Cleaning System

For our tube cleaning services Projectile utilizes a system known as mechanical tube cleaning.  This system involves using specially designed mechanical devices (tube projectiles) to remove deposits from the interior of various condenser and heat exchanger tubes.  There are other methods for removing deposits from condenser and heat exchanger tubes including high pressure/ultra-high pressure water jetting (hydro-blasting) and chemical cleaning.  Relative to these two methods, mechanical tube cleaning is superior due to that fact that mechanical tube cleaning is significantly faster.  On average our crews can clean approximately 6,000 tubes per 12 hour shift.  The speed associated with our process ultimately leads to cost savings for our customers.

How it Works

  1. Insert projectile into the tube
  2. Using Projectile’s specialized water gun pull the trigger allowing water to flow.  The specialized pumping system increases available water pressure to approximately 350-450psi.  The water creates force behind the projectile and allows it to clean the tube traveling at approximately 15 feet per second.
  3. The operator should hold the trigger until the gun’s pressure gauge has dropped.  This drop signifies that the projectile has exited and the tube has been cleaned.
