Moisture in compressed air negatively affects both the productivity and workmanship of abrasive blasting contractors. The harmful effects of wet air include the clumping or clogging of abrasive grit, inconsistent and/or excessive flow of abrasive, corrosion of ferrous abrasives, and damage to blast machine valves and controls. When abrasive media…
Sometimes a fuel gas combustion device such as a small boiler, catalytic heater, or burner does not require dehydrated gas. Fuel gas free of liquids and mists is good enough. For these small fuel gas applications, Van Air Systems offer F200 series filters for basic fuel gas coalescing. These inline…
Water in compressed air lines causes paint and coatings to drip, bubble, and “fish-eye”. Wet compressed air may also dilute the paint, both increasing the cure time and affecting the adhesion of the coating to the steel surface. Properly cooling, drying, and filtering compressed air eliminates re-work and increases the…
Oil and gas companies use pressurized natural gas (i.e. instrument gas) to operate pneumatic actuators and controllers. These controllers are essential for managing process flows at wellheads, compressor stations, and processing plants. Pneumatic actuators controllers direct the opening and closing of valves, the level of fluids in tanks and separators,…
Abrasive blasting exposes a steel substrate to atmospheric humidity, and blasting contractors must contend with “flash rusting”. Flash rusting is surface corrosion that appears on steel when it’s not coated quickly enough. The presence of liquid water in compressed air exacerbates a contractor’s problems with flash rusting. Liquid water in…
