The design pressure is 27.5Mpa and the hydraulic test pressure is 41.25Mpa. Can the ER304 welding wire reach the strength requirement?In addition, what welding wire is used in the welding argon arc welding between 20# steel tubes? Given a better buy on the market, piping design pressure of 4.0Mpa.
Base metal 0Cr18Ni9 welding rod A137 argon arc welding wire H0Cr20Ni10Base material 20 welding rod E4303 welding wire TIG-J50High pressure pipeline, must do welding assessment, welder welding process according to the welding, pipeline group, the gap, etc. must strictly check, welding rod must bake, insulation
For 308 moderate price, mechanical properties can be guaranteed!
