ASTM standards are widely used international specifications for metal materials, components, and industrial products, especially in the fields of oil & gas, petrochemical, power generation, shipbuilding, and EPC projects.
This ASTM Standards hubs provides a structured reference to ASTM material standards related to flanges, pipes, pipe fittings, bolting and gaskets. These standards define the requirements for chemical composition, mechanical properties, heat treatment, testing, and certification, ensuring product quality and performance in demanding service conditions.
On this page, you can quickly find the relevant ASTM standards by product type and application, and access detailed specification pages for technical reference and project use.
ASTM Standards by Product Type
ASTM Flange Material Standards
ASTM flange materials are primarily defined by forging standards, covering carbon steel, alloy steel, and stainless steel used for pressure and high-temperature service.
Common ASTM flange material standards include:
- ASTM A105 / A105N – Carbon steel forgings for flanges and valves
- ASTM A182 – Alloy steel and stainless steel forgings
- ASTM A350 – Low-temperature carbon and alloy steel forgings
- ASTM A694
ASTM Pipe Material Standards
ASTM pipe standards specify the material requirements for seamless and welded pipes used in high-temperature, high-pressure, and corrosive environments.
Typical ASTM pipe material standards:
- ASTM A106 – Seamless carbon steel pipe for high-temperature service
- ASTM A53 – General purpose carbon steel pipe
- ASTM A335 – Seamless alloy steel pipe
- ASTM A312 – Stainless steel seamless and welded pipe
- ASTM A213 standard for seamless ferritic and austenitic alloy-steel tubes used in boilers, superheaters, and heat exchangers
- ASTM A358
- ASTM A790
- ASTM A789
ASTM Pipe Fitting Material Standards
ASTM pipe fitting standards cover butt-welding fittings made from carbon steel, alloy steel, and stainless steel, widely used in industrial piping systems.
Common standards include:
- ASTM A234 – Carbon and alloy steel pipe fittings
- ASTM A403 – Stainless steel pipe fittings
- ASTM A420 – Low-temperature carbon steel fittings
- ASTM A860
ASTM Bolting Material Standards
ASTM bolting standards define the material and mechanical requirements for stud bolts, threaded rods, bolts, and nuts used in flange connections and pressure equipment.
Key ASTM bolting standards:
- ASTM A193 – Alloy steel and stainless steel bolting materials
- ASTM A194 – Carbon and alloy steel nuts
- ASTM A320 – Low-temperature bolting materials
- ASTM A354 – High-strength alloy steel bolts
- ASTM A453
ASTM Gasket Material Standards
ASTM gasket-related standards mainly focus on metallic and non-metallic gasket materials, as well as testing and classification methods.
Frequently used standards include:
- ASTM A240 – Stainless steel plate, sheet, and strip for gasket materials
