Hastelloy Fitting
Hastelloy fittings are durable components used to alter direction, connect pipes of varying sizes, or branch off fluid pathways within a piping system. Their robust construction ensures long-term durability in dynamic flow environments where erosion and corrosion are simultaneous threats. These fittings are designed to handle internal pressure changes, high-velocity flow, and mechanical stress from fluid movement or thermal expansion. They are often installed in tight or complex piping layouts where flexibility and precision are essential. Due to their high resistance to stress corrosion cracking and metal fatigue, these fittings are used in mission-critical systems such as reactors, agitator outlets, and scrubber loops.
