ASME SA537 pressure vessel uses heat-treated carbon-manganese-silicon steel plate.The steel plates supplied by this standard are divided into three categories, namely SA537Gr1, SA537Gr2, and SA537Gr3. The maximum thickness of steel plates corresponding to these three grades is limited to: SA537Gr1 is not more than 100mm;The thickness of SA537Gr2 does not exceed 150mm;The thickness of SA537Gr3 does not exceed 150mm.
First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of RINA EH40 hull structural ship plate welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, RINA EH40 hull structural ship plate. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.
Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the RINA EH40 hull structural ship plate steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the RINA EH40 hull structural ship plate steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the RINA EH40 hull structural ship plate steel sheet on the truck Good luck.
