Spreading flanges, as well as aligning the bolt holes on flanges can be fraught with challenges. Whether you are in a refinery, petrochemical plant, midstream operation, water-wastewater plant, offshore production platform, or anywhere flanges are found, no two sets of companion flanges are the same.
Flanges can be different diameters and different series depending on the amount of pressure the piping is rated for. Some flanges don’t have a gap between them, such as those found in water service. Some large flanges have a wide gap between them, such as those found in a in a natural gas storage facility. Sometimes even small flanges can be harder to spread than larger ones.
Once the new gasket is inserted or the isolation blind is in place, the next required step is to realign the bolt holes so that the flange bolts can be reinserted. Some flanges can be realigned easily with a screw driver, and others can be so far out of alignment or so rigid as to require a maintenance crew to cut the flanges out and start over.
