How to choose non-ferrous metal pressure vessels?

Non-ferrous metal pressure vessels as a more common type of equipment in the process of modern industrial development, in the current stage, to ensure efficient industrial production plays an irreplaceable role. With the continuous progress of modern science and technology and industrial modernization level, industrial production for non-ferrous metal pressure vessel equipment requirements is increasingly high. Based on this, this paper focuses on the knowledge of non-ferrous metal pressure vessels.

What is a pressure vessel?

The so-called pressure vessel equipment generally refers to a relatively good sealing and can withstand a certain pressure of the container equipment. At this stage of the industry, such as the chemical industry, energy industry, scientific research institutions, and military industry, etc., the relevant products will be applied to the pressure vessel equipment. For pressure vessel equipment, the main material is metal, and with the increasing maturity of pressure vessel production technology, more and more other materials are applied to the actual production process, including non-ferrous materials.

What are the principles of non-ferrous metal pressure vessel selection?

1. Selection of non-ferrous metal pressure vessel materials, must take into account the working conditions of the vessel, such as temperature, pressure, and media characteristics; material properties, such as mechanical properties, physical properties, and chemical properties; processing properties, such as welding properties and hot and cold processing properties of materials; economic and reasonable performance, such as the price of materials, manufacturing costs, and service life.

2. The use temperature of steel does not exceed the maximum temperature corresponding to the upper limit of the allowable stress in each steel grade. However, it should be noted that carbon steel and carbon-manganese steel in the long-term use of higher than 425 ℃, should take into account the tendency of graphitization of carbides in steel. Austenitic steel use temperature higher than 525 ℃, the carbon content of the steel should not be less than 0.04%. For < -20 ℃ low-temperature vessel materials should also be Charpy "V" notch impact test.

3. Non-ferrous metal pressure vessel pressure components with steel quality and specifications in line with the corresponding national standards, ministerial standards, and related technical conditions, and should be made by the flat furnace, electric furnace, or oxidation furnace refining. Steel manufacturers must ensure the quality, and provide a quality certificate. The certificate should list the furnace number, batch number, measured chemical composition, and mechanical properties (austenitic stainless steel may not provide the value), as well as melting, heat treatment state.

4. Non-ferrous metal pressure vessel non-pressure components with steel must have good weldability.

5. In consideration of non-ferrous metal pressure vessels under pressure components have sufficient strength, must consider its toughness to prevent brittle damage under applied load.

Non-ferrous metal pressure vessels are widely used in petroleum, chemical, machinery, metallurgy, energy, aerospace, and other fields, and play an indispensable role in the production, transportation, reaction, and other aspects of the above fields. Nanjing Suntech Metal Equipment Co., Ltd. conducts many tests on non-ferrous metal pressure vessels before they leave the factory, and the quality qualification rate is guaranteed.
