(PDF) Effects of finish rolling temperature and yield Effects of finish rolling temperature and yield ratio on variations in yield strength after pipe-forming of API-X65 line-pipe steels September 2020 Scientific Reports 10(1):14742
Nov 16, 2014 · [1,2] However, ERW steel pipes are vulnerable to the defect formation because its welding zone has dierent characteristics compared to the base material. This limits the applica-tion possibility of ERW steel pipes and has become a major concern. In this study, a critical assessment has been made for the electric resistance welded Alloy-Steel-PipeHow to ensure the quality of ERW carbon steel pipe ERW carbon steel tube has this processing technology, which has the advantages of post welding heat treatment, eliminating residual stress in weld and heat affected zone, refining grain, small heat affected zone and fast heating speed. It can greatly improve welding speed and weld quality.
Plastic deformation during the manufacture process of electric resistance welded (ERW) pipe determines the stressstrain relationship of the steel pipe, which affects the collapse pressure of offshore pipelines. To track the deformation history of the pipe, the entire process was simulated via finite element analysis using a solid element. Effects of finish rolling temperature and yield ratio on Sep 08, 2020 · Jo, M. C. et al. Effects of coiling temperature and pipe-forming strain on yield strength variation after ERW pipe forming of API X70 and X80 linepipe steels. Mater. Sci. Eng. A
May 28, 2020 · Hot rolled seamless steel pipe:Hot rolling is relative to cold rolling, cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling above the recrystallization temperature. Identification of the selective corrosion existing at the The mechanism of grooving corrosion in electric resistance welded (ERW) carbon steel pipe in sea water was investigated. Grooving corrosion is a selective localized corrosion of the weld.
Aug 20, 2017 · These numbers are 10, 20, 30, 40, 60, 80, 100, 120, 140 and 160. In most sizes of pipe, schedule 40 corresponds to standard and schedule 80 corresponds to extra strong. Dimensions and the mass in kg/m of different sizes of steel pipe with varying wall thicknesses is shown in Fig. 2 . Figure 2. Pipe Martensite Island - an overview ScienceDirect TopicsSteel is often reheated and this process is referred to as tempering. The steel is tempered at a temperature below a temperature known as critical temperature. This temperature depends on the alloy and the rate of heating, but mostly it is below 1,360°F (738°C).

The present invention provides a method for heat-treating seam-welded constructions of hardenable steel and ferrous alloys with reduced weld-zone hardness and improved weld-zone ductility and toughness. This method consists of heating the seam weld rapidly with a secondary heat source to a temperature greater than the martensitic start temperature but not greater than the lower critical US6632295B2 - High tensile strength hot-rolled steel sheet US6632295B2 US09/864,473 US86447301A US6632295B2 US 6632295 B2 US6632295 B2 US 6632295B2 US 86447301 A US86447301 A US 86447301A US 6632295 B2 US6632295 B2 US 6632295B2 Authority
