All weld seams in electric-resistance welded A53 Grade B pipe must be heat treated after welding to a minimum of 1,000°F (540°C) to eliminate low untempered martensite. ASTM A335 P9,P11,T22,T91 Carbon steel pipe ASTM A53 IS widely use in generating plants. water, air, natural gas transmission, gas pipelines, mechanical and pressure applications. Development of a FAD-Based Girth Weld ECA Procedure:Feb 24, 2009 · This paper focuses on the experimental verification of the procedure. Some particular issues related to girth weld ECA are discussed first. The experimental database includes both full-scale and wide plate test results. Most of the full-scale data are from pipes of API Grade X70 (483 MPa); a few were X65 (448 MPa) and X60 (414 MPa) grades. High Grade Steel Pipeline for Long Distance Projects at Furthermore, further development was attempted to obtain steel with far higher grade (API 5L X120), for the gas transportation at a pressure much higher (25 MPa) than the one proposed in the latest studies. 4) Eni Projects on High Pressure Eni started in the 1995 a cluster of projects on very high strength steel (involving X70, X80 and
In the production of API 5L X70 LSAW Steel Pipe, plates of grade X70 are formed by the molding machine into round shape then welded through double-sided submerged arc welding. Details of API 5L Grade X70 LSAW Steel Pipe:Manufacture:Longitudinally Submerged Arc Welding. Size:O.D.:4061422mm W.T.:860mm. Length:3-12M or specified length as required. Ends:Plain End, Beveled End, Grooved. Chemical Composition of API 5L Grade X70 LSAW Steel Low Hydrogen/Low Alloy Electrodes - ESAB Welding & CuttingAtom Arc 8018 electrodes deposit 1% Ni weld metal. They are used primarily to weld high-tensile steels in the 70-80 ksi (483-552 MPa) tensile strength range, especially where notch toughness at temperatures as low as -40°F (-40°C) is required.

What is the meaning of API 5L pipe steel?Oil and gas transmission pipeline steel plate API Spec 5L:(X42 L290NB, X46 , X52 L360NB, X56 , X60 L415NB, X65 L450MB , X70 L485MB, X80 L556MB). X70 used for West-East gas pipeline project pipeline API Spec 5L steel compared to the yield strength of the steel X80 which corresponds to, but the tensile strength than steel X70.
Features. 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%. Therefore, the structure of the pipe is composed of acicular
