Grades of material used for pipes, fittings, flanges acc to various Astm standards

What are ASTM Grades..

ASTM standards define the specific manufacturing process of the material and determine the exact chemical composition of pipes, fittings and flanges, through percentages of the permitted quantities of carbon, magnesium, nickel, etc., and are indicated by "Grade".

Below you will find as an example 3 tables with chemical requirements for..

– Flanges ASTM A182 Grade F304, F304L F316L – Pipes ASTM A312 Grade TP304, TP304L, TP3016L – Fittings ASTM A403 Grade WP304, WP304L, WP316L

ASTM Materials

Pipes

1. A106▸ This specification covers carbon steel pipe for high-temperature service. 2. A335▸ This specification covers seamless ferritic alloy-steel pipe for high-temperature service.

Fittings

1. A234▸ This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction. 2. A420▸ Standard specification for piping fittings of wrought carbon steel and alloy steel for low-temperature service.
