ASTM A403 WP316 Fittings are a grade of pipe fittings that are made up of a high oxidation resistant material. This material is also corrosion resistive, pitting resistive and can withstand strong chemicals and acids.この材料の高温と圧力耐性により、A403 WP316の肘は、パイピングの腐食性高圧湾曲の下でより良いパフォーマンスを発揮します。 The corrosion in fluid direction changing joints is high. Due to the impact of the fluid flow, the fitting might break if there was corrosion and or thermal expansion.
