The theoretical weight of seamless steel pipe is the weight per meter of steel pipe calculated by the calculation formula: meter weight = (outer diameter - wall thickness) * wall thickness * 0.02466, in which the outer diameter refers to the farthest distance between the outer walls on both sides of the steel pipe, and the wall thickness is the thickness of the seamless steel pipe wall. The weight per meter of P355GH steel thickness seamless steel pipe is calculated by the formula. If you want to get the weight of the whole seamless steel pipe, you should multiply the actual length of the steel pipe.
The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. p355gh steel thickness, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.
As the thickness and hardness of p355gh steel thickness increase, the tendency to crack at the cutting edge increases. In order to prevent the p355gh steel thickness from cutting cracks, preheating should be carried out before p355gh steel thickness cutting. Special attention should be paid to preheating to make the entire p355gh steel thickness interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole p355gh steel thickness cannot be preheated, the partial preheating method can be used instead.
