Overview:

WP347H elbow is a specific type of pipe fitting used in various industries, particularly in high-temperature and corrosive environments, It contains high levels of chromium, nickel, and molybdenum, which provide excellent resistance to corrosion and high-temperature strength.

The design is to change the direction of fluid flow in a piping system. It has a curved shape, typically with a 90-degree or 45-degree bend, allowing fluids to change direction smoothly. The elbow is connected to the pipe using welding, threading, or socket welding techniques.

As WP347H stainless steel offers several advantages, including excellent resistance to oxidation, corrosion, and high-temperature environments. It also provides good mechanical properties, such as high tensile strength and toughness and commonly used in industries such as chemical processing, petrochemical, oil and gas, power generation, and other applications involving high-temperature and corrosive environments. They are suitable for handling various fluids, including acids, alkalies, gases, and liquids.
