How to use a stainless flange

For fastening two pipes or pieces of equipment together, a stainless steel flange is the device to reach for. Generally welded or screwed onto the end of one side and then bolted to the other, there is an abundance of flanges available with their own unique sets of advantages and disadvantages. The most frequently used type would be a weld neck flange, with others such as the slip-on, threaded, and blind flange all having their distinctive benefits.

Taking the necessary precautions to properly align a flange is crucial before fastening it. Negligence in this endeavor can result in messy and even hazardous leakage, or in a worst-case scenario the flange fracturing. Utilizing a level will ensure its correct positioning, imparting peace of mind about its structural integrity.

After making sure that the flange is level and properly aligned, the next step is to secure it in either a welded or bolted manner. When welding, ensure that the welding rod and gas are correct for the flange material to prevent any damages causing potential leakage. Tightening the bolts should be done with care as well – making sure that both the size and type of bolts are appropriate and using the right amount of torque. An excessive amount of torque can cause harm to the flange while not applying enough might mean it won’t be fastened securely enough.

Putting the flange in place is only the beginning–completion requires testing it for any running away of fluids. The tried and true method of inspection is to fill the setup with water and search for any dampness. If no water appears, the flange has been properly installed. However, if the liquid is visible, the flange must be either replaced or remedied.

Fitting a stainless steel flange doesn’t need to be tricky. You can be certain of a sound, impermeable bonding if you observe the steps noted.
