Seal-Tex XT

Online sealing up to 500°C.

ASME PCC-2 certified Seal-Tex XT makes leakages along steam lines nothing but a bad memory.

Steam is one of the most important tools in modern industry. It is a key factor for heat transfer, sterilization, propulsion and drive, motive, atomization, cleaning, moisturization, humidification.

A very large part of the energy requirement of an industry is used by boilers to generate steam, and it is estimated that an average of 37% of all the energy consumption of factories is dedicated to steam production, with peaks of 81% in paper production, 57% in food processing and 42% in the chemical industry.

However, steam must be transferred from the boiler to the place where it is needed, and this is made through steam lines. Along these steam lines, several sources of losses can be found.

While leakage on steam valves depends on the quality of the sealing device, and can be virtually eliminated by using Sealtek Zero Leakage System, the main location of steam loss along pipelines is the connection between two pipes. Threaded connections represent the biggest source of steam loss, as the expansion and contraction of steam along the thread during startup and shutoff, together with the corrosion caused by carbonic acid found in most systems, often result in joint failure and leakage. Welded connections offer limited additional benefits, as the coefficient of thermal expansion of the welding is always different than the pipe’s, making the joint prone to corrosion.

The cost of a steam leakage is difficult to determine, as the leakage area is often unknown and visual inspections can be dangerous for the operator. However, considering the cost of the loss from one single 1mm wide hole, and multiplying for all the steam loss in a factory, it becomes clear that eliminating such leakages is always a very productive investment, regardless of its size.

Seal-Tex XT special high temperature online repair tape, able to reach a maximum temperature of 500°C and requiring less than 5 minutes to completely seal a leakage, can guarantee leak-free operations and energy savings beyond imagination.

Applying Seal-Tex XT requires as little effort as immersing the tape in water, applying the tape and letting its resin react. No preparation is needed to the target area, and no interruption of the steam line is required.

Unlike welding, Seal-Tex XT can easily resist the corrosion from carbonic acid, and will provide over 10 years of hassle-free sealing.

Seal-Tex XT is ASME-PCC2 certified for the repair of pressure equipment and piping.
