What is Weldolet and Sockolet?

Weldolet, Sockolet and Threadolet are olet pipe fittings that can supply an outlet from a larger pipe to a smaller one (or one of the same size). Weldolet has a butt welded connection, threadolet has threaded connection, and sockolet has welded connection.

What is the run size on a Sockolet?

Conventional Run Size Combinations

How do I order Weldolet?

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.

What is a flat Threadolet?

This is a threaded connection used for making 90 degree branching from the main run of pipe. Flat thredolets are used on welding caps, elliptical heads and flat surfaces. Each outlet size is available to fit any run curvature. Outlet sizes fit a number of run pipe sizes, and fittings are marked accordingly.

What is an O let?

Branch Connection fittings (also known as O’lets) are fittings which provide an outlet from a larger pipe to a smaller one (or one of the same size). The main pipe onto which the branch connection is welded is usually called the Run or Header size.

What is a Weldolet fitting?

A weldolet is a branch butt-weld connection fitting that is adhered to an outlet pipe to minimize stress concentrations in the piping area.

What is a Sockolet fitting?

A Sockolet is similar to a Weldolet, with the difference that the branch pipe is connected to the run pipe, via the fitting, with a socket weld connection as per ASME B16. 11. Likewise Weldolets, Sockolets are used to make a 90-degree pipe branch. Sockolets may be “size on size” or “reducing”.

How does weldolet fit on a pipe?

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.

Can you XRAY a weldolet?

Available with male-socket weld or male threaded outlets. Insert Weldolet® is another contoured butt-weld branch connection used in less critical applications. Like the Sweepolet®, the attachment welds are easily examined by radiography, ultrasound and other standard non-destructive techniques.

When should I use Threadolet?

Threadolets are used for smaller pipe sizes and low-pressure applications.

What is an OLET fitting?

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).

What is a Branchette?

The Insert Branchette® is used in higher stress header connections where an exceptionally smooth outside and inside transition contour of the run pipe and the ease to radiograph the attachment weld is required. The Socket-Weld and Threaded Branchettes are generally used in vents, drains, and instrumentation piping.

What is a threadolet fitting?

What is Threadolet? Threadolet is a type of self-reinforced branch fitting developed by a Company called Bonney Forge. It is used whenever threaded branch connections are required from the pipe header. Mostly, it is used for small size piping with a low-pressure application.

What is the pressure rating of a threadolet?

This olet is available in class 3000 and class 6000 pressure-temperature ratings. Threadolet® is a Registered Trademark of Bonney Forge. Being a trailer product, threadolets are designed for specific conditions based on Process piping Code ASME B31.3, hence, Dimension is also specified by the designer.

What is the taper angle of the NPT thread?

Note b: Reference dimension. – NPT Thread taper angle = 1/16 taper = 1 deg. 47 min = 0.75 in./ft . – The angle between the sides of the thread is 60 deg.

What is the difference between threadolets and dimension?

Threadolets are designed for specific condition based on Process piping Code ASME B31.3, hence, Dimension is also specified by the designer. However, MSS-SP-97 provide dimension requirements for standard 90° self-reinforced branch connection with butt, socket and threaded end types
