What are olets?
Olets are also called branch connections. Olet fittings are a family of forged products used to make 45 or 90 degrees integrally reinforced branch connections (deviations) from a run pipe (also called, header pipe) to a branch pipe (outlet pipe). The common types of branch fittings are Weldolet, Thredolet, Sockolet, Latrolet, Elbolet, Nipolet, Sweepolet. MSS-SP 97 is the important specification covering reinforced branch connections. Hebei Haihao Group provides all kinds of olets for many years.
Pipe branch fittings are used to create integrally reinforced connections from a run pipe (header pipe) to an outlet pipe, at 45 or 90 degrees, alternatively to connections made with butt weld tees, reinforcing pads and saddles. This type of forged fittings are otherwise called “branch connections”, or “branch fittings”, or “pipe branch outlet fittings” or, simply, “Olets”.
Outlet fittings are forged products with high strength and clear cost advantages over conventional pipe branching techniques.
How are they installed? Quite easily: on one side, the fittings (example a weldolet) is fixed onto the run pipe with a full penetration groove weld and, on the other side, welded (or screwed) on the branch pipe. Of course, the header pipe shall be properly cut in the proximity of the area where the pipe needs to be branched.
