ASTM B338 (titanium)

WELDED (ERW TUBE)

ASTM A179 / A334 carbon steel

 

ASTM A249 / A269 (stainless steel)

ASTM A789 (duplex, superduplex)

In addition to carbon steel grades, alloy steel, stainless steel and nickel alloy, pipes materials include ductile iron (typically used for water transportation or sewage systems), non ferrous grades (aluminium, copper, brass and related alloys as cupronickel for marine application), titanium, zirconium and plastic (p v c pipes are the most common, but other materials are availabe such as pe, pp, abs, etc.). The most common tube material is instead alloy steel and stainless steel.
