ASTM A403 WP317-S Stainless Steel Fitting For High Corrosion And Temperature Resistance
ASTM A403 WP317-S Fitting
ASTM A403 WP317-S Elbow is a pipe fitting that complies with the American Society for Testing and Materials (ASTM) standards and is particularly suitable for stainless steel piping systems. Specifically:
ASTM A403 means that this fitting follows ASTM's A403 standard, which details the requirements for stainless steel pipe fittings for low and high temperature applications.
WP stands for "Welding Pipe" and 317 is a type of stainless steel. 317 stainless steel is a chromium-nickel-molybdenum alloy that has better corrosion resistance and higher heat resistance than 304 or 316 stainless steel.
Elbow is generally used in pipe fittings for parts that change the direction of the pipe. It can have different angles, such as 180 degrees, 90 degrees, 45 degrees, etc.
This type of elbow is often used in industrial applications that require high corrosion resistance and temperature resistance, such as chemical, oil and gas industries. When choosing this type of fittings, it is important to make sure that they meet specific application needs and safety standards.
