JIS B2312 JAPANESE STANDARD STEEL PIPE FITTING 90° 45° LR/SR ELBOW SUS304
Overview:
JIS B2312 is a Japanese Industrial Standard for steel pipe fittings， including elbows， tees， couplings， and more. The SUS304 elbow refers to an elbow fitting made of SUS304 stainless steel material.
SUS304 stainless steel is commonly used in a variety of industries because of its excellent resistance to corrosion and oxidation， as well as its durability. The JIS B2312 SUS304 elbow is designed to change the direction of fluid flow in a piping system， ensuring smooth operation of the system.
The JIS B2312 SUS304 elbow is manufactured to meet the standards set by JIS， which ensure that the fitting has appropriate dimensions， pressure ratings， and material properties. These fittings come in various sizes to accommodate different pipe diameters and can be used for both high and low-temperature applications.
