Outlet pipe fitting (also called pipe branch fittings,branch connection fittings,tube base or O’lets) are fittings which provide an outlet from a larger pipe to a smaller one(or one of the same size).The types of pipe branch fittings are weldolet,thredolet,sockolet,latrolet,elbolet,nipolet,sweepolet,insert weldolet,brazolet,coupolet.
The mostly used outlet pipe fittings are sockolets and threadolets,weldolets and elbolets.
The weldoflange is a combination of a welding neck flange and a supposedly weldolet,while the nipoflange is a combination of a welding neck flange and a nipolet.
Weldolet is the most common fitting of branch connection.It has a beveled end,and connected to the branch pipe by butt welding,so it belongs to butt weld fittings.The design of the weldolet minimizes stress concentration and provides overall reinforcement.There are three pressure grade STD, XS, and Sch160 for the weldolet.
Sockolet(socket weld outlet)
Sockolet,its run pipe is the same as weldolet,but its branch connection is socket-welded.The pressure is usually 3000# and 6000#.
Thredolet,its run pipe is the same as weldolet,but its branch connection is threaded without welding.The pressure is usually 3000# and 6000#.
Latrolet is for 45°branches,its connection with the branch pipe can be butt welding,socket welding and threaded.
Elbolet is used to provide branch connections on long radius elbows or short radius elbows.Its connection with the branch pipe can be butt welding,socket welding and threaded.
Nipolet usually used for valve installation and exhaust.There are two grades of thickness: XS and XXS.Its length is from 3-1/2 inches to 6-1/2 inches,and its end is socket or female thread.
Sweepolet,its shape is wavy and overall reinforcement.It is a butt welding connection with branch pipe,commonly used in low pressure pipelines.
Insert weldolet(insert welding outlet)
Insert weldolet is another contoured butt-weld branch connection used in less critical applications.The ends are slanted to encourage this procedure,and in this manner the weldolet is viewed as a butt-weld fitting.Weldolets are intended to limit stretch fixations and give essential fortification/reinforcement.
Coupolet pipe fittings are intended for use in flame/fire insurance sprinkler frameworks and other low weight pressure piping applications.Produced with NPT female threads for 300# administration and are UL Listed and F.M. affirmed.
Brazolet is utilized generally abroad as of late,it is utilized to interface or connect the fortified fittings.It happens of conventional associating ways.The assortment of brazolet is made in phenomenal Forgings.It’s intended for use with KLM and IPS metal or copper tubing.It’s accessible with socket or threaded connections.
