The steel plate used for containers and pressure vessel has to bear different pressures and strengths due to the manufactured containers. The normal pressure is generally 31.4MPa or higher; the working temperature is usually between -20 ℃ -450 ℃, and sometimes lower than -20 ℃. According to the working conditions and processing technology of the container, the P235GH boiler steel sheet, steel plate used for the container must have good cold bending and welding performance. Besides, it should have good plasticity and toughness, high temperature short-term strength or long-term strength performance.

In the welding process, effectively preventing the stress and deformation of the component during the welding process is the key to ensuring the welding quality of the wear-resistant steel plate. In the welding process, after spot welding each part according to the position of the drawing, ensure that the size is consistent with the drawing. The welding method of symmetrical multi-layer multi-pass welding is adopted to ensure the appropriate welding process parameters, which can effectively prevent the welding deformation of the p235gh boiler steel sheet, wear-resistant steel plate.

Booking space and making power of attorney (ten copies of order); the data of the original order shall be correct and consistent to the greatest extent when making the order, so as to reduce the frequent changes in the subsequent process. For booking with the company's seal for booking space, if the accessories for booking space (such as the price confirmation document of the shipping company) need to be provided, they can only be booked with all of them. Obtain the shipping space allocation receipt and extract the ship name, voyage number and B / L number information.
