First, whether or not remanufactured products do not meet the standards of quality; second, whether there is a direct dismantling of the “five major assemblies†by scrapped companies; and third, whether there are any unauthorized actions to manufacture other companies’ products; Whether there is no re-manufactured logo and enters into social sales; whether there is illegal import of old parts from abroad for remanufacturing; and whether there is any act of remanufacturing products for new car production; Major environmental pollution problems; eight is whether there are other violations of laws and regulations.
Pressure vessel steel plate covers a range of steel grades that are designed for use in pressure vessel, boilers, heat exchangers and any other vessel that contains a gas or liquid at high pressures.
Familiar examples include gas cylinders for cooking and for welding, oxygen cylinders for diving and many of the large metallic tanks that you see in an oil refinery or chemical plant.
There is a huge range of different chemicals and liquid that that stored and processed under pressure. These range from relatively benign substances such as milk and palm oil to crude oil and natural gas and their distillates to highly lethal acids and chemicals such as methylc. So of these processes need the gas or liquid to be very hot, whilst others contain it at very low temperatures. As a result there is a wide variety of different pressure vessel steel grades that meet the different use cases.
In general these can be divided into three groups. There is a group of carbon steel pressure vessel grades. These are standard steels and can cope with many applications where there is low corrosion and low heat. As heat and corrosion have more effect on the steel plates chromium, molybdenum and nickel are added to provide additional resistance.
