What is thread O let?

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. Threadolets are available in full size or reducing size.

What is the difference between a weldolet and an Threadolet?

The mainly differences are the connection surface, weldolet ends in plain or beveled to weld on the the branch pipe, sockolet ends in socket type that to insert branch pipe. Threadolet is insert branch pipe and with screw connection. Weldolet: Compatible with higher pressure and simple connection, cost lower.

How do I choose a 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 the difference between weldolet and Sockolet?

What is the difference between a Sockolet and a Weldolet? Sockolets belong to the “socket fittings” family and are available in classes 3000#, 6000# and 9000#, whereas Weldolets are buttweld fittings. Sockolets are used for lower pressure applications, and smaller pipe diameters, than Weldolets.

What is a Branchette?

Integrally Reinforced Branch Connections designed and manufactured by WOI are known as Branchettes®. There are existing designs in four families. These families consist of the Butt-Weld Branchette (BWB), Insert Branchette® (BIB), Socket-Weld Branchette® (SWB), and Threaded Branchette® (THB).

What type of weld is a Weldolet?

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 reducing Weldolet?

Weldolet is 90° branch connection. It Comes in full size or reducing size (Full size is when you take a branch of the same size as run pipe size for example 3 inch to 3 inch. And reducing size is when branch size is less than run pipe size 3 inch to 1 inch)

What is a weldolet fitting?

What is a flat weldolet?

The flatolet is basically “olet” to be used on flat surface or on the very large run sizes (where the difference of curvature becomes less and less significant. The basic design of a flatolet is same except the flat base. The weldolet for run sizes larger than 36″ (DN 1800) will be considered as flatolet.

Can you weld threaded pipe?

1) If a threaded fitting is fully made up tight, and the connection is then seal-welded, the differential thermal expansion of the pipe fitting relative to the pipe due to the heating from the weld can cause enough stress in the weld to actually cause a crack in the weld.

What is a Weldolet fitting?

What are the dimensions of a 3000 lb threadolet?

3000LB Threadolet Dimensions 1 There is a ASME B16.11 and MSS SP 97 standard for outlet pipe fittings. 2 In both ASME and MSS standard, threadolet is available in class 3000 and class 6000, diameter 1/8” to 4” for the branch. 3 The threads is in accordance with ANSI/ASME B1.20.1.

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 are the limitations of threaded fittings?

Threaded fittings are limited to 50% of the rated pressure of the pipe. Warning: Never use plastic pipe fittings and pipe with compressed air or gas. For technical drawings and 3-D models, click on a part number. Fittings with stainless steel collar have a reinforcement on the female threads to prevent the threads from cracking.

What is the difference between a weldolet and threadolet?

When you use a weldolet, you need to weld a pipe or fitting directly to the branch fitting, and a threadolet, you should screw the connecting pipe or fitting (e.g. valve) to the branch connection. We marked all carbon steel forged fittings with Grade, Lot No, Size, Standard and Pressure Ratings.
