Non-standard pressure vessel equipment
1. The manufacturing process of the pressure vessel can be generally divided into: raw material acceptance process, scribing process, cutting process, descaling process, machining (including planing, etc.) process, rolling process, group-pairing process, welding process (product welding test) Board), non-destructive testing process, hole drilling process, general inspection process, heat treatment process, pressure test process, anti-corrosion process.
2. Different welding methods have different welding processes. The welding process is mainly determined according to the material, grade, chemical composition, weldment structure type and welding performance requirements of the workpiece to be welded. First of all, we must determine the welding methods, such as hand arc welding, submerged arc welding, tungsten argon arc welding, gas metal arc welding, etc. There are many types of welding methods, which can only be selected according to specific conditions. After the welding method is determined, the welding process parameters are determined, and the types of welding process parameters are different. For example, hand arc welding mainly includes: welding rod type (or brand), diameter, current, voltage, welding power source type, polarity connection, welding Number of layers, number of tracks, test methods, etc.
Pressure vessels used extensively in the chemical industry, due to the corrosive nature of the medium, the reaction conditions, such as cold and heat, transportation, use, and man-made problems, there will always be such enamel layer damage, causing unnecessary production stoppage, such as large area falling off. It is recommended that you only return to the factory to re-enamel. The pressure vessel is expensive, and there is no need to update the entire equipment when it is damaged. This requires the use of a suitable repair method. It should be repaired immediately with JS916. Otherwise, the pressure vessel will be corroded by the solvent in the container. The damage of the surface will rapidly expand, resulting in unpredictable losses such as production stoppages, safety accidents and environmental pollution.
The pressure vessel is a comprehensive product involving many industries and multi-disciplines. Its construction technology involves metallurgy, machining, corrosion and corrosion protection, non-destructive testing, safety protection and many other industries. Pressure vessels are widely used in chemical, petroleum, machinery, power, metallurgy, nuclear energy, aviation, aerospace, marine and other sectors. It is an indispensable core equipment in the production process and an important indicator of the level of equipment manufacturing in a country. For example, the reaction device, the heat exchange device, the outer casing of the separation device, the gas-liquid storage tank, the pressure shell of the nuclear power reactor, and the steam drum in the power plant boiler system are all pressure vessels. With the continuous advancement of technologies such as metallurgy, machining, welding and non-destructive testing.
The company can undertake non-standard pressure vessels such as carbon steel and low alloy steel according to user needs. Companies adhering to the "management and pragmatic, elaborate, safe and reliable, customer satisfaction, continuous improvement," the quality policy, and constantly improve and improve the company's quality assurance system to ensure high-quality product quality and user satisfaction continues to improve.
