How many elbows can a plumbing vent have?

The answer to having elbows can a plumbing vent is- for vents longer than 40 feet (12 192 mm), the pipe size shall increase by one nominal pipe size for the entire developed length. To bend vent pipes at 90 degrees, you can install a 90-degree bend. Besides the preceding, is it possible for plumbing vent pipes to have 90-degree angles? I strongly recommend avoiding the sharp, 90-degree elbow designed for venting above the waterline. Although you may have vent piping, you cannot use the tight 90-degree elbow ? sometimes known as a Vent Elbow or a Vent Shoulder ? if the joint is below the water level, typically at the bottom of the sink.
