What is Threadolet？
Threadolet is a high-strength, specialized pipe fitting for smaller-diameter branches branching off from the main pipeline. Threadolet is a type of branch pipe platform, and the name of the branch pipe platform is usually followed by “-olet.”
How Threadolet Works
Threadolet has a short section with threads and a welding interface at the bottom that matches the main pipe.
Welded connection to the main pipeline
The welding connection with the main pipe is a permanent connection. This is the special feature of Threadolet. Its bottom is a depression that matches the outer diameter of the main pipe. When installing, drill a hole in the main pipe and buckle the Threadolet on the hole.
Threaded connection to branch pipe
The connection with the branch pipe is a detachable connection. The internal thread of the branch pipe must match the external thread of the Threadolet. Screw the branch pipe into the Threadolet and finally wrap the raw tape or apply thread sealant on the thread.
Advantages of Threadolet
Very High Strength
Threadole utilizes a forging process, which eliminates defects such as pores and slag inclusions. This results in greater strength. Furthermore, its structure is not a simple short section; its outward-facing design features a geometric shape with a reinforced saddle.
Excellent Sealing
The connection between the threadolet and the main pipe is a permanent full-penetration weld or fillet weld, fundamentally eliminating the risk of leaks. The connection to the branch pipe is a threaded connection with ultra-high-precision threads. PTFE tape and thread sealant are used on the threads to enhance the sealing strength.
Save space and materials
Threadolet is significantly more compact than traditional tees, which require connecting three pipe sections. Threadolet can be used as an alternative when space is limited and a tee is not an option.
Easy installation
Threadolet can be installed at any position on the main pipe, such as the top, bottom, side, etc. When maintenance is required, the threaded connection of the branch pipe can be unscrewed at any time, and the subsequent maintenance cost is low.

Application of Threadolet
Due to its excellent performance, Threadolet has since been used in extreme scenarios such as high temperature, high pressure, flammable and explosive environments.
- Oil and gas: refineries, offshore platforms, etc.
- Power industry: steam pipelines, power plant boilers
- Chemical and petrochemical: reactors, high-temperature and high-pressure pipelines
