p235gh equivalent astm material heavy plate 60mm thick

At present, the design of oil and gas P235GH equivalent astm material pipeline is based on the yield strength of steel, and high transmission work requires higher yield strength of p235gh equivalent astm material steel. For welded wire pipe, the yield strength decreases after rolling and decreases with the increase of strength.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with p235gh equivalent astm material ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

As the thickness and hardness of p235gh equivalent astm material increase, the tendency to crack at the cutting edge increases. In order to prevent the p235gh equivalent astm material from cutting cracks, preheating should be carried out before p235gh equivalent astm material cutting. Special attention should be paid to preheating to make the entire p235gh equivalent astm material interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole p235gh equivalent astm material cannot be preheated, the partial preheating method can be used instead.
