ASTM A333 Gr. 8 specification covers seamless steel pipe for Ultra-low temperature service.
JIS G3458 Standard is made for heat resistant alloy steel pipes that are used for high temperature conveying fluid pipes for heaters and boiler tubes.
Stainless Steel pipe and tubes have well to excellent corrosion resistance and easy finishing attributes.
The welded steel pipe refers to a steel pipe which is welded and formed into a shape of a circle or a square by bending a steel strip or a steel plate, and has a seam on the surface thereof.
ASTM A178 covers minimum-wall-thickness, electric-resistance-welded tubes made of carbon steel and carbon-manganese steel intended for use as boiler tubes, boiler flues, superheater flues, and safe ends.
ASTM A178/A 178M Standard Specification for Electric-Resistance-Welded Carbon Steel and Carbon-Manganese Steel Boiler and Superheater Tubes
Piping Elbow and Piping bend are not the same, even though sometimes these two terms are interchangeably used.
A 3D pipe bending is a pipe bend that the bend radius is 3 times the pipe outside diameter.
The 5D bend in pipe bending is an accomplishment in pipe manufacturing, and not all pipe companies can provide it.
ASTM A105 is the standard specification for carbon steel forgings for piping applications including flanges, fittings and valve parts, etc.
