The olets can be put on pipes that connect them to create a smooth transition between them. Olet fittings in general permit an outlet to a bigger pipe from another pipe. The attached video will walk you through proper installation and usage of threadolets.
Branch connections are commonly used by the Weldolet. They give solid reinforcement to reduce strain contractions and also prevent them from happening again. It’s joined to the outlet pipe if installed right. The ends on this olet are rounded to make the welding process more efficient, thereby making it abutt-weld fitting.
Although the Threadolet uses the Weldolet as its branch, it is attached to the Threadolet joins the Weldolet by using an olet thread. The bore of this thread is with the outlet bore. the existence of the threading ensures that no welding will be required, since the thread makes installation easier. mdiyg4ne12.
