Characterization of Duplex Stainless Steel / Cold Reduced

The dissimilar 2 mm thickness plates of duplex stainless steel and cold reduced low carbon steel,conforming to AISI 2205 and IS 513_2008 CR2_D were butt welded by means of gas tungsten arc welding using argon as shielding gas.The butt welding joint arrangement was used for this experiment using E 309L electrode as filler metal.Difference Between Seamless And Erw PipeAll Carbon steel pipe such as Casing pipe and Tubing pipe made to API specifications uses seamless or electric-weld supplying processes.There are many Differences between Seamless ERW Pipe.The main Difference is that the Seamless Piping is suppliers by hot-working steel or,if necessary,by subsequently cold-finishing the hot-worked product Difference between mild steel and carbon steel pipeDifference between mild steel and carbon steel pipe.Difference between mild steel and carbon steel pipe refers to the machining surface has a smaller spacing and small valley roughness..Two peaks or troughs which the distance between the two (the pitch) is small (at 1mm or less),it is difficult to distinguish with the naked eye,so it belongs to the micro geometry errors.

Federal Register : Carbon Steel Butt-Weld Pipe Fittings

If an importer imports carbon steel butt-weld pipe fittings (butt-weld pipe fittings) from Malaysia and claims that the butt-weld pipe fittings were completed in Malaysia using finished or unfinished butt-weld pipe fittings manufactured of non-Chinese origin,the importer is required to complete and maintain the importer certification,attached Federal Register : Carbon Steel Butt-Weld Pipe Fittings These formed or forged pipe fittings are used to join sections in piping systems where conditions require permanent,welded connections,as distinguished from fittings based on other fastening methods (e.g.,threaded,grooved,or bolted fittings).Carbon steel butt-weld pipe fittings are currently classified under subheading 7307.93.30 of the Federal Register : Circular Welded Carbon Steel Pipes and Apr 02,2020·See Antidumping Duty Order Circular Welded Carbon Steel Pipes and Tubes from Thailand,51 FR 8341 (March 11,1986).Back to Citation [FR Doc.2020-06911 Filed 4-1-20; 8:45 am]

Welded vs.seamless steel pipe American Piping Products

Welded vs.seamless steel pipe As industrial applications have evolved and grown more complex,the piping products and systems that serve them have had to keep pace.While many pipe manufacturing methods exist,the most prominent discussion in the industry compares electric resistance welded (ERW) vs.seamless (SMLS) steel pipe.Welding and Joining GuidelinesThe main consideration in weld joint design of Ni-/Co-base alloys is to provide sufficient accessibility and space for movement of the welding electrode or filler metal.Slightly different weld joint geometries are required compared to those for carbon or stainless steel; in particular,a larger included weld angle,wider root opening (gap),and
