Stainless steel branch outlet is a forged reinforced pipe fitting, mainly used for connect pipelines,especially in high-pressure,high-temperature,large-diameter,thick-walled pipelines,and has gradually replaced traditional branch pipe connection methods.
Stainless steel branch outlets are forged from stainless steel.Branch outlet pipe fittings are providing an outlet from a larger pipe to a smaller one.They are used to instead of connected fittings such as reducing tees,reinforcing plates, and reinforced pipe sections.There are many types based on the varity piping connected methods that weldolet,
thredolet,sockolet,latrolet,elbolet,nipolet,sweepolet and flangolet.Why they are popular,because its outstanding advantages,such as safety, reliability,low cost and simple construction.
Weldolet
Weldolet is most common and economical of all stainless steel branch outlet,it is welded to the main run pipe (larger size) and connceted to the branch pipe (small size).The shape of the Weldolet ensures little stress concentration on the branched pipe,providing an integral reinforcement.The weldolet has three pressure levels:STD,XS and Sch160, and the main production standards are MSS SP-97 and GB/T 19326.
