Tank Welding Vacuum

Tank Welding Vacuum Testing System is the first tank testing technological advancement in over 10 years. The Tank Welding Vacuum Testing System utilizes digital technology to transform and analyze acoustical signals at the source. Our system is the only one available that will automatically calculate pressure adjustments for interior levels of product as well as exterior water levels to ensure both accuracy of testing and protection of the tank.

Vacuum Lab Testing

Testing asphalt pavement materials such as aggregate, reclaimed asphalt pavement (RAP) and mixture specimens often requires that samples be dried to a constant mass. Most labs accomplish this using convection ovens or fan drying, depending on sample type. The National Center for Asphalt Technology (NCAT) recently completed a study to determine if Vacuum ovens are an economically feasible alternative to convection ovens and fan drying in an asphalt pavement lab. The underlying premise of a Vacuum oven is that at low pressures, water converts to steam at a much lower temperature, which should enable more efficient drying.

Vacuum Systems

A partial Vacuum may be generated by increasing the volume of a container. To continue evacuating a chamber indefinitely without requiring infinite growth, a compartment of the Vacuum can be repeatedly closed off, exhausted, and expanded again. This is the principle behind positive displacement pumps, like the manual water pump for example. Inside the pump, a mechanism expands a small sealed cavity to reduce its pressure below that of the atmosphere. Because of the pressure differential, some fluid from the chamber (or the well, in our example) is pushed into the pump's small cavity.

Vacuum Varnish Tank

Through technological improvements, 30% or more paint can be saved than traditional technology. Flange on the vat brim, which is solid steel and through tempering setting treatment and surface sheet metal fabrication, won't deform and the seal effect can be guaranteed. high-quality insulation, thermal insulation, to ensure the temperature does not leak ,improve efficiency and save energy. The bottoms of vat and cone through anti-sticking treatment. Paint permeability and evenness is high, so product quality can be more greatly assured.
