What is Weldolet?
Weldolets, the most common type of branch fitting, are part of the buttweld fixings family and are available in a wide variety of dimensions.
The Weldolet is a welded piece that has bevelled ends on both ends. It attaches to the run pipe on one side and the branch pipe on the other. A weldolet is a type of pipe fitting that is used to branch off the main piping line to a smaller line at a 45 or 90-degree angle. The Weldolet’s shape ensures that there is little stress on the pipe branch and provides an integral reinforcement.
Weldolets are typically made of carbon steel or stainless steel and are welded onto the main pipe to create a secure and permanent connection.
A weldolet is a branch butt-weld connection fitting that is attached to an output pipe in order to reduce stress concentrations in the piping region. The most frequent type of branch fitting is the weldolet. They’re a type of Buttweld fitting that comes in a number of sizes. They are used as an alternative to fittings such as elbows or tees, which can be more complex to install and may require additional support.

Introduction to Hastelloy C-22
Hastelloy C-22 (UNS NO6022) is a Ni-Cr-Mo based alloy with a nickel content of about 60%. It is a versatile nickel chromium molybdenum tungsten alloy that has better overall corrosion resistance than other existing nickel chromium aluminum alloys, including Hastelloy C-276, C4, and 625 alloys. Hastelloy C22 alloy has excellent resistance to pitting corrosion, and C-22 alloy has excellent resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking. At the same time, C-22 also has a certain ability to resist the formation of grain boundary precipitation in the welding heat affected zone, which enables it to adapt to many types of welding conditions.
Hastelloy C22 alloy has excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. It has excellent resistance to oxidation in aqueous media, including mixed acids of wet chlorine, nitric acid, or oxidizing acids containing chloride ions. It also has ideal resistance to the reduction and oxidation environments encountered in the process, and tungsten further improves its corrosion resistance.
