HYDROTESTING/PNEUMATIC TEST OF VARIOUS EQUIPMENT

Hydrostatic (Hydro) Testing is a process where components such as piping systems, gas cylinders, boilers, and pressure vessels are tested for strength and leaks. Hydro tests are often required after shutdowns and repairs in order to validate that equipment will operate under desired conditions once returned to service.

The pneumatic test is a type of pressure test for checking system integrity under the pressurized condition and applied to systems where the hydro-static test is difficult to apply. A pneumatic test uses air, nitrogen, or any non-flammable and non-toxic gas.

RETUBING OF CONDENSER /HEAT EXCHANGER/COOLER AND FIN TUBES

Steam condenser repair & retubing is a highly labour-intensive and time-consuming process. Typically, hundreds of tons of tube material have to be removed and replaced several pounds at a time.

Production processes and techniques have to be effectively applied to maintain consistent and efficient movement of the tube material involved. Tens of thousands of tube to tube sheet joints have to be properly expanded and controlled, not just for the hydro test, but to ensure leak-tight integrity for the remaining life of the plant.

TRITECH provides contractor support and turnkey services for condenser repair and retubing. With the expectation that field conditions will be different for every project, TRITECH condenser repair engineers and field technicians draw from processes and experience to anticipate and prepare for difficulties that may be encountered.

Seemingly insignificant differences can have major impact on schedule, performance, and quality – issues that TRITECH is focused on addressing to the highest standard.

Tritech has developed relationships with the major tube suppliers, condenser and heat exchanger engineering consultants, tube coating specialists, maintenance contractors, specialist heat exchanger tool manufacturers, OEMs, numerous subcontractors, nonferrous metal merchants, and major power plant constructors, all of which are utilized to repair condenser problems of different magnitudes.

ANTI-CORROSIVE PROTECTIVE COATING

Ceramic putty is a versatile easy-to-use rebuilding putty with excellent abrasion and chemical resistance. This product is heavily filled with aluminium oxide and can be built up to an inch in thickness or more.

Typical applications are for rebuilding of pump casings, slurry tanks, weld seams or anywhere requiring the restoration of metal components.

Carbide putty is a more abrasion resistant putty than SAR, which is used primarily in areas requiring more resistance to fine slurries either in liquid or powder form. Common applications are in coal mills, chutes, ash hoppers or deflector plates in FGD systems
