What is Weldolet?
Weldolet is the most common among all pipe olet. It is ideal for high pressure weight application, and is welded onto the outlet of the run pipe. The end are bevelled to facilitate this process, and therefore the weldolet is consider a butt weld fitting.Weldolet is a branch butt weld connection fitting that is adhered to outlet pipe to minimizes stress concentrations. And it provides overall reinforcement.Normally it has the same or a higher schedule than the run pipe schedule, and offers a variety of forged material grades, such as ASTM A105, A350, A182 etc.
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.
