Tubesheet Cladding

A precisely applied epoxy cladding that:  Seals the tube-to-tubesheet joint – Adds 2,000 pounds in push-out strength – Replaces lost metal — Protects tubesheet indefinately from further damage.

Tube-End Coating

Copper based alloys can erode within the first foot or so of the inlet end due to turbulence.   Other tube materials can deteriorate because of galvanic or microbiological issues.

Full-Length Tube Coating

Protect the tube from further deterioration – fills pits and seals holes.


In addition to restoration and protective services for tubesheets and tubes, look to Plastocor,® Inc. for protective coatings on the rest of the circulating water system.

Flange Sealing

Seals waterbox to condenser flange – Stops air inleakage.

Innovation in Tube Testing

Plastocor Developes Semi-Automatic Tube Testing System 

Pressure testing is a common industry practice for detecting leaks in heat exchanger tubes. Plastocor has developed equipment to pressure test individual heat exchanger and condenser tubes. This Advanced Pressure Testing System (APTS) is a computer assisted semi-automatic system which has proved to be faster, more accurate, and less fatiguing to operate than conventional equipment.
In use since 2015, this equipment is a fully portable, field ready, system that fully complies with ASTM A1047/A1047M-08 (2019) – Standard Test Method for Pneumatic Leak Testing of Tubing.

New Addition to Our Fleet

                  The Power of Water

Ultra-High-Pressure (UHP) water blasting is used by Plastocor, Inc. to prepare surfaces for coating. UHP consists of water pressure in excess of 30,000 psi but delivered at low volumes. This method is particularly useful when removing coatings (including rubber) without damaging the metal substrate. To better address the market and to improve reliability, we have acquired a fleet of electrically driven pumps. Versus diesel driven pumps, these units are more reliable and can be quickly setup inside and close to the worksite. These units are PLC controlled which provides variable pressure and lower starting amps.
