Longitudinal welded joints samples of X70 and X80 API grade steel pipes were exposed to a deaerated 1% NaCl solution containing CO2, at temperatures in the range of 25 ºC to 80 ºC for 48 hours. (PDF) Low temperature tensile properties of line pipe steelsLongitudinal welded joints samples of X70 and X80 API grade steel pipes were exposed to a deaerated 1% NaCl solution containing CO2, at temperatures in the range of 25 ºC to 80 ºC for 48 hours.
§ 192.113 Longitudinal joint factor (E) for steel pipe. The longitudinal joint factor to be used in the design formula in § 192.105 is determined in accordance with the following table:Specification API 5L PSL1|PSL2 Line Pipe SpecificationGR. B, X42, X46 and X52, X56, X60, X70 and X80, now the big steel mills and factories have developed steel grade for X100 and X120 measures of pipeline steel. Steel pipe of higher steel grade, relatively have higher requirement of raw materials and production, the carbon equivalent between different grade of steel is strictly controlled. Carbon Steel Pipes, Carbon Steel Tubes, Steel Pipe, Steel Carbon Steel Pipes :ASTM A53/ASME SA53 Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless Grade A; Grade B :ASTM A106/ASME SA106 Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service
New or existing buried pipe, made of carbon or alloy steel, fabricated to ASTM or API material specifications. Welded pipe, joined by welding techniques permitted by the ASME code or the API standards. Piping designed, fabricated, inspected and tested in Hydrogen embrittlement of high strength pipeline steels Dec 01, 2006 · The microstructure of all the steels consisted of bands of pearlite distributed amongst ferrite in a structure clearly elongated in the longitudinal direction of the pipe. The average grain sizes measured on a longitudinal section were 8, 4 and 3 m, respectively, for X60, 80 and 100 producing hardnesses of 200, 224 and 252 VHN. LSAW Steel Pipe, Longitudinal Submerged Arc Welded - Longitudinally welded steel pipes are used in onshore and offshore oil and gas pipelines requiring critical service, high performance and tight tolerances. LSAW pipe are also used in conveyance of flammable & nonflammable liquids, and as structural members in construction projects.
Longitudinal Strength and Stiffness of Corrugated Steel Pipe BRIANT. HAVENS, F. WAYNE KLAIBER, ROBERT A. LOHNES, AND - LOREN W. ZACHAR-¥ Iowa, as well as other states, has experienced several failures of corru gated metal (CMP) culverts, apparently because of inlet flotation. In Iowa, most of these failures have occurred on secondary roads. Longitudinal vs Transverse Impact testing Technical blogAug 14, 2017 · T he term longitudinal or transverse refers to whether the grain in the steel in the test piece runs the length of the rectangle (longitudinal) or across the width of the rectangle (transverse).. In an impact test, the test piece is shaped into a rectangle, with the notch being made in the middle of the length of the rectangle on one side. SK18895A3 - Method of longitudinal welding of pipes with Longitudinal welding of pipes to flat steel strips, in which the pipes are pressed against the strips and are longitudinally displaced during the welding process by means of a known conveying device (10), is characterised by the fact that, simultaneously with production of the top seams by means of a UP welding process, the bottom seams are produced by means of a combined MPG pulse and
Atlas Steels can also supply stainless steel pipe with an abrasive polished external finish suitable for architectural applications. Welded Pipe Welded stainless steel pipe is manufactured from 2B or HRAP stainless steel strip formed to shape, longitudinally welded and annealed. Steel Standards - ASTM InternationalASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.

Steel pipe longitudinal cracks. Longitudinal cracks are formed as a result of excessive soil and traffic loads or inadequate pipe bedding. Visible longitudinal cracks observed at top and invert inside the pipe should be more severe than those on the outside because tensile stress occur at top and invert portion of the inside of the pipes.
