Nickle Alloy Flat Welding Flange Hastelloy C4 Catalytic Support System
Nickle Alloy Flange, also known as a flange rim or flange, is a part that connects pipes to each other at the ends, and it is also used on equipment inlets and outlets for connecting two pieces of equipment, such as a reducer flange. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolt, which together form a combined sealing structure.
Welding Process:
Hastelloy C4:
This Nickel-Chromium-Molybdenum alloy tolerates high temperatures and gives a designfreedom in areas where weld geometry makes excessive heat buid-up unavoidable. Resistance to general and localised corrosion and stress corrosion cracking is generaly similar to Hasteloy C-276.With its high contents of Chromium and Molybdenum Hastelloy C-4 is able to withstand both
oxidizing and non-oxidizing acids, and is resistant to pitting and crevice attacks in thepresence of chlorides and other halides. Like
other nickel alloys, Hastelloy C-4 is ductile, easy to form and weld. Hastelloy C-4 is also known as Nicrofer 6616.
Key Features
Hastelloy C-4 offers the following key features: Excelent resistance to stress-corrosioncracking and to oxidizing atmospheres at hightemperature. xceptiona resistance to a wide variety of chemical process environments including, hotcontaminated minera acids,so vents,chorineformic and acetic acids,and salt waters.
