Shell & Tube Heat Exchanger Service

OnSite and OffSite Services.

T.H. Industrial Solutions Inc. (THS) has been servicing industrial heat exchangers and solving process problems across Canada since 2009. THS head office is located in Pickering, Ontario with a 6,000 square foot service center in Hamilton, Ontario.

(1-2 Days) On or Offsite

CHEMICAL FLUSHING

A portable chemical flushing unit consists of a pump, tank, filter and hoses. THS service technicians pump a citrus based cleaning chemical or mild acid solution through the heat exchanger for 6-8 hours, during the flushing any debris is collected in the filter.

*The level of success for this cleaning method is determined by the amount and type of contamination. If the scale has hardened, which is very common on heating applications, the chemical flush effectiveness can be limited.
TESTING AND TUBE REPAIRS

THS is equipped to provide pressure testing, individual tube vacuum testing and plugging leaking tubes on or offsite.

*Repair and/or replacement turnaround is based on part availability

(2-3 Days) On or Offsite

TUBE CLEANING

Recommended for heat exchanger tubes that have hardened scale, the bonnet must be removed. High pressure cleaning and/or Roto-Jet rods with cleaning brushes and drills are inserted into each tube to grind or cut away scale or contamination.

TUBE REPLACEMENT

THS is also equipped to provide pressure testing, individual tube vacuum testing, complete tube replacement and tube plugging both onsite and at our Hamilton Service Center.

*Repair and/or replacement turnaround is based on part availability

(2 – 3 Weeks) Offsite

CHEMICAL CLEANING

Tube bundle or complete heat exchanger is serviced at one of our service facilities. A mild acid solution is pumped through the heat exchanger for 6-8 hours, during the flushing all debris is collected in the filter. Before and after flow rates are recorded to gauge the effectiveness of the cleaning.

Extreme fouling applications - tube bundle is submerged in a heated chemical bath.
After 4 hours the bundle is removed and high pressure washed.
If the contamination remains the process is repeated.

BORESCOPE INSPECTION
A borescope is utilized to examine the tube internals before and after chemical cleaning. Pressure testing is completed on both the bundle and shell.

(2 – 10 Weeks) Offsite

REPLACEMENT OR CUSTOM OPTIONS

Stock replacement delivery is approximately 2-4 weeks; Custom fabricated can be manufactured in approximately 6-10 weeks. Without drawings, the bundle will need to be removed and measured to fabricate a replacement.

SHELL & TUBE HEAT EXCHANGERS ISSUES

  1. When vacuum breakers or thermostatic vents are not installed or functional the tube can be sucked in and break.

  2. If the bundle is subjected to temperature extremes, (thermal shock), the tubes will develop spiral cracks.

  3. On steam applications, harmonics can occur. This constant vibration can cause the steel baffles to eventually cut into the copper tubes.

  4. Chemical corrosion resulting from interaction between the heat exchanger and the circulated fluids.

  5. this results in higher corrosion and restricts heat flow
