Branch Outlet Fittings

Branch Fittings  - Weldolet, Sockolet, Threadolet, Elbolet, Nipolet to MSS SP-97


Branch fittings also named Outlet fittings or Saddle fittings, mainly used for branch pipe connected, instead of the connected fittings such as reducing tees, reinforcing plates, and reinforced pipe sections. The branch fittings are popular because its outstanding advantages, such as safety and reliability, low cost, simple construction, improved media flow channels, standardization, and convenient design selection. It is especially widely used in high-pressure, high-temperature, large-diameter, and thick-walled pipelines to replacing traditional branch pipe connection methods.

Based on the varity piping connected type, branch fittings have many different types, include Weldolet, Sockolet, Threadolet, Elbolet, Nipolet, Laterolet, Sweepolet, Flangedolet(Nipoflanged, Weldoflanged) Coupolet, Flexolet etc.

As a professional supplier for outlet branch fittings in China, KAYSUNS supplying commonly sockolets and threadolets, weldolets and elbolets in standard MSS SP-97 with full dimension and fast delivery. For other type outlets fittings, we can manufacture and supply accordingly. All of our branch fittings are forged and machined by CNC, and supplied with certificate EN10204 3.1/3.2. Third party inspection from SGS, BV, ABS, DNV, TUV, Lloyd’s, Intertek etc are available for our prodcuts.

The commonly type of branch olet fittings we supplied:

WELDOLET

Weldolets  are the most well-known among all the olets and are well-suited for high pressure weight applications. These are principally sorted as butt weld fittings, as these are welded into the branch pipe. .

A Weldolet makes a 90° branch connection and – comes in full size or reducing for a straight piece of pipe. A weldolet is designated by the run length by the branch length. For example a 6-inch weldolet on a 10-inch pipe would be a 10×6 Weldolet. A weldolet is designed to minimize stress concentrations and provide integral reinforcement without the need for reinforcing the weld.

SOCKOLET

A sockolet has the same basic design as a “weldolet” or “threadolet” where the major difference is that a sockolet has a socket for welding while the weldolet has got a buttweld connection. This makes a 90° branch and comes in full size or reducing for a straight piece of pipe. Sockolets are available in Class 3000, 6000 and 9000 for high pressures.

THREADOLET

A threadolet has the same basic design as a weldolet. However the main difference is the fitting has a female threaded connection to link to the branch connection. This makes a 90° branch and comes in full size or reducing for a straight piece of pipe.

Typically, it is in the size range of 1/2″ to 2″ and is welded over a hole either drilled or burned in the pipe.

ELBOLET

An elbolet is used on 90° long radius elbows (most common), short radius elbows (seldom used) and can be used on 180° returns. It is typically used for instrumentation connections and thermowells. Thermowells are tubular fittings used to protect temperature sensors installed in industrial processes. A thermowell consists of a tube closed at one end and mounted in the process stream.

Elbolets can be used as a drain connection when there is not enough room to use a Weldolet. The Elbolet is available with buttweld, socketweld or threaded connections.
