A nonconventional heat treatment in API X70 steel samples was carried out by heating the steel up to 1050 C and holding for 30 min at this temperature.

The mechanical properties of steel pipe have great effects on the integrality and operation safety of gas transmission pipeline. In order to reduce the cost of the steel pipe, the high Nb X80 pipeline steels with the different alloying systems have been used in the Second West to East Gas Transmission Pipeline Project. Nevertheless, an investigation into the effects of chemical composition on

API 5L X70 steel pipe has a minimum yield strength of 70,300 psi or 485 Mpa. The current X70 steel pipe are all controlled micro alloyed carbon manganese steels. The micro alloys elements are mainly Nb, V and Ti, and the total content of micro alloys does not exceed 0.15%.

The API 5L specification covers seamless and welded pipes to convey oil, gas, water in the natural oil & gas and petrochemical industries. API 5L line pipes are available in multiple carbon steel grades, designated as Grade B, X42, X46, X52, X56, X60, X70, X80 and in PSL1 or PSL2 specification levels.

API 5L seamless & welded pipe American Piping Products stocks API 5L pipe in grades B and X42 X120. Scope. ANSI / API 5L specifies the manufacture of two product levels (PSL1 and PSL2) of seamless and welded steel pipe for the use of a pipeline in

Aug 04, 2017 · The evolution of microstructure, texture and mechanical properties of API X70 pipeline steel after different thermomechanical treatments has been studied using a combination of X ray diffraction and electron backscatter diffraction (EBSD).

microstructure and mechanical properties. The objective of this study was to verify the safely replacement of an old steel (X60) by a modern steel (X70) in a recently designed transport line of iron ore. 2. Materials and Experimental Procedures The X60 steel was manufactured by traditional hot rolling and normalising operations while the X70

API 5L X70. Grade X70 means 70000 PSI minimum yield strength and 82000 PSI minimum ultimate tensile strength. API Standard Specification for Line Pipe. The American Petroleum Institute specification API 5L addresses seamless and welded steel line pipe for pipeline transportation systems in the petroleum and natural gas industries.

The grades of line pipe steel based on API SPEC 5L specify a series of minimum mechanical requirements and not specific material composition, though the specification does list the maximum composition percentage for any component. Therefore each mill will provide slightly different steel
