Heat Treatment

To help clients overcome thermal challenges, STANLEY Inspection provides electrical surface heating, refractory dryout and curing, ladle drying, and onsite pre- and post-weld heat treatment. We also offer high-velocity fuel-fired heat treatment, furnace heat solutions, and thermal stress analysis.

In the field of heat treatment and thermal technology, STANLEY Inspection has the manpower and equipment to cover all design, engineering, treatment, inspection, and maintenance work, with the power to work within major shutdowns should the need arise. Our ongoing commitment to exceptional onsite service and the highest level of quality has earned us a worldwide reputation for heat treatment excellence.

Electrical Resistance

Electrical resistance heat treatment services offered by STANLEY Inspection include onsite preheating; hydrogen de-gassification; and post-weld heat treatment of pipework, welded fabrications, and pressure vessels.

Flexible electrical resistance heating elements are manufactured in a range of sizes to suit a wide array of applications and are connected to either low-voltage (65-volt) or high-voltage (240-volt) power sources. Each low-voltage power source is rated at 50 kva, has a minimum of 6 individually controllable outlets, and can power a maximum of 18 heaters of 2.7 KW. Temperature is controlled via pre-programmable microprocessor-based modules and temperature measurement is made by pre-calibrated digital temperature recorders. All temperature measuring equipment is calibrated in accordance with national standards.

STANLEY Inspection has more than 7500 KW of applied resistance heat at our disposal.

High-Velocity Fuel

STANLEY Inspection has a range of high-velocity burners fired by either LPG or diesel oil for the onsite heat treatment of large fabrications, pressure vessels, and temporary furnaces. Typical high-velocity fuel applications include caustic or sulfuric liquid storage tanks, reactor vessels, hydro-active vessels, LPG storage spheres, and steel furnaces.

The use of STANLEY Inspection high-velocity burners is an effective method of curing and driving out moisture from refractory materials. Working under carefully controlled conditions, we eliminate the risk of damage that can be caused by spalling and thereby extend the life of the refractory.

Temporary Furnaces

STANLEY Inspection has developed transportable, lightweight, low-thermal-mass temporary furnace installations for the post-weld heat treatment of large-pressure vessels and fabrications. These furnaces are designed as a fast, convenient, cost-effective alternative to permanent furnaces and the high cost of transporting components to fixed installations. Temporary furnaces can be equipped with either gas- or oil-fired burner systems and both temperature control and distribution are equal to or better than most fixed furnace installations.

Refractory Dryout

STANLEY Inspection has extensive experience in the field of refractory dryout and in controlled heating and ventilation for the drying of specialized linings. Our expertise in these areas ensures maximum flexibility and minimum downtime.

By utilizing state-of-the-art equipment, including digital process controllers, fully proportional fuel actuators, and solid-state features, our engineers are able to provide flexible service that meets the most demanding of specifications. Moisture is removed by strictly controlling heating rates to avoid damage to lining materials. Typical applications for this procedure include:

  • Induction furnace refractory dryout
  • Induction furnace cold start
  • Blast furnace refractory dryout
  • Coal gassification plant refractory dryout
  • Refinery cracker unit refractory dryout
  • Aluminum holding furnace refractory dryout
  • Cement kiln pre-heaters and coolers
  • Incinerator refractory dryout
  • Drying/curing of phenolic and catalyzed epoxy linings

STANLEY Inspection utilizes today's most advanced heating and ventilating operating procedures to produce optimum refractory properties, ensuring maximum flexibility and minimum downtime.

Electrical Surface Heating

STANLEY Inspection has decades of experience in the engineering of electrical surface heating (trace heating) systems, meeting the requirements of an array of applications. We offer today's most comprehensive range of surface heating systems, including self-regulating heating cables and constant-wattage trace heating cables (Isopad/Pyrotenax BICC ).
