JIS B2312-1997 Steel butt-welding pipe fittings
This Standard specifies the steel and nickel-chromium ferro-alloy seamless pipe fit-tings to be fitted by butt-welding, mainly to pressure service pipings, high pressure service pipings, high temperature service pipings, alloy steel pipings, stainless steel pipings, low temperature service pipings, and steel pipes for fired heaters.
JIS B2312 is a Japanese Industrial Standard for pipe fittings,
including elbows. SS304 refers to stainless steel grade 304, which
is a common type of stainless steel used in various industrial
applications.
Therefore, a JIS B2312 SS304 elbow would be a stainless steel elbow
fitting that conforms to the JIS B2312 standard and is made from
grade 304 stainless steel. This type of elbow is typically used in
piping systems for its corrosion resistance and durability.
