What is a return bend in a sprinkler system?
A return bend is the piping arrangement for pendent sprinklers where piping stems from the top of the branch pipe (riser nipple), runs horizontally (arm over), and then down to the sprinkler (drop). Components of a return bend in a fire sprinkler system.
What is an Armover sprinkler?
An armover is defined in Section 3.5. 3 as a horizontal pipe that extends from a branch line to a single sprinkler or a sprinkler above and below a ceiling. There is no limitation on the length of the arm-over. Thus, an armover is defined differently from a branch line; it is not part of Section 9.3.
What is the purpose of 90 degrees bend?
The main application area of an elbow (90 degree) is to connect hoses to valves, water pressure pumps, and deck drains. These elbows can be made from tough nylon material or NPT thread.
Why are return bends needed for pendent sprinkler heads on a wet system?
A return bend is the piping arrangement for pendent sprinklers where piping stems from the top of the branch pipe (riser nipple), runs horizontally (arm over), and then down to the sprinkler (drop). Return bends are used primarily to prevent sediment accumulation in the drop to the sprinkler.
How close can a hanger be to a sprinkler head?
The distance between a hanger and the centerline of an upright sprinkler shall not be less than 3 in. (75 mm).
What is 1.5D bend?
1.5d Pipe Bend is one of the piping fittings used in piping applications to connect pipes together. There are different types of fittings such as tees, elbows, bends and couplings. There are different types of piping bends with different dimensions such as the Pipe Bend Radius 1.5d.
What is 90d elbow?
A 90 degree elbow is a pipe fitting which you can used to change the flow direction in a 90 degree.It is also called “90 bend” or “quarter bend”. As a joint between two pipes,the 90 degree elbows are also used as a railing ends or corners on a level installation.
What is a 5D bend?
A 5D pipe bending is a pipe bend that the bend radius is 3 times the pipe outside diameter. The RADIUS of a 5D pipe bend is actually what is 5 times the nominal diameter. So if you had a 10″ diameter pipe, the radius of the centerline of the bend would be 50 inches.
What are the types of bend?
Angled Bend—The bend is formed on one side of the bend line or equally on both sides.
