Talking about the New Requirement to Valve Manufacturing Industry from Chemical Designing Industry
As we all know, the development of China's chemical industry has undergone a process of development from scratch, from primary to intermediate and even to the current more advanced level. Chemical design industry development process, but also closely related with this process, synchronization. In different stages of development, chemical design industry on the valve manufacturing requirements, but also different. First, a brief description of the traditional requirements In China's chemical industry development in the primary and intermediate stages, due to the country's economic fundamentals, the construction of chemical projects to save investment, economical and practical, so the valve manufacturing industry is not too high, mainly Emphasis on low-cost low-cost, to meet the use can be. At the same time, the valve manufacturing is mainly based on imitation and part of the development. Valve product sample content is relatively simple, indicating the parameters and material selection is relatively small. Valve design in the design industry in a groping, conservative state, the design industry and valve manufacturing collaboration and cooperation is relatively simple. Second, the current development trend of the chemical industry and the design of the valve manufacturing new requirements Since the reform and opening up in China in the 1980s, China's chemical industry has made great progress in the development of earth-shaking changes. Chemical design industry has also undergone great changes. Due to the continuous introduction of foreign advanced technology and the continuous development of domestic chemical technology, the variety of chemical products is increasing and the varieties are getting more and more complete. With the improvement of national economic level, the chemical design industry is also demanding higher and higher requirements on the valve manufacturing industry. In particular, the valve reliability, durability and other requirements are getting higher and higher, and taking into account the economy of the valve (price The rationality). At the same time, the requirements of the chemical design industry on the sample of valve materials are also getting higher and higher. With the chemical design industry gradually with international standards, the original design institutes engaged in engineering design have engaged in large-scale chemical project construction general contracting chemical engineering company restructuring, the division of labor more and more detailed, cooperation with the valve business change More complex, and thus the valve manufacturing industry requirements are getting higher and higher, more and more. Due to the rapid development of the chemical industry, coupled with the restructuring of the design industry, more and more types of chemical plants, more and more construction scale, the chemical design and construction industry, the valve manufacturing industry generally has the following requirements: ①valve varieties , Specifications should be complete, reliable performance, should be close to or reach the international advanced level, taking into account the existing domestic variety specifications, the best is the international and American standard products can produce. Material choice is bigger. Many companies only produce GB products or produce only American standard products. When ordering, they also indicate that both standard products can be produced. In fact, they are just a standard valve according to another connection standard flange bolt holes will do. This is actually a non-standard product that is detrimental to the quality of the project and is very dangerous. Valve companies should also continue to improve product quality, and constantly develop new products to meet the operational needs of chemical production plant. Such as automatic venting valves for venting venting at the high point of equipment or piping for liquid handling equipment and a regulated bleed valve for continuous or intermittent venting that can be used to stabilize the pre-valve operating pressure without frequent commissioning. According to Understand, at home and abroad are still not solved. We always think this is a problem to be solved. The hospital has done some work in this area, some breakthroughs, welcomed the valve companies to cooperate with us. In addition, the original valve varieties also need to be improved. Such as the ball valve is a good valve, but the sealing performance of the valve rod still needs improvement, can be safely used for liquefied gas, liquid ammonia and other flammable gas occasions. Plunger valve stem of the seal is good is its original characteristics, but the hospital used in a project, the leak point is at the stem, the problem is very serious, non-reform can not. So, etc., in this regard is not listed, and welcome the valve companies to work together with us to solve these problems, catch up with the world level. ② valve samples, data parameters and descriptions should be complete, to be able to meet the new requirements. For example: the valve model (or order number) representation to be concise, easy to remember, and can distinguish between different valves to ensure unique ordering. For newer (or more important) valve varieties, should explain the selection method and calculation methods, so that users can better choose. The sample should also indicate the valve manufacturing standards, acceptance criteria, test conditions, etc., and some should also indicate the number of switches (open) and so on. The design department of the sample data is also sent to learn. Due to the restructuring of the design department, it is very important that some institutes have set up professional pipe control professionals to ensure the sample materials of the pipe professional. ③ production capacity should be on the grade, product components to minimize outsourcing to ensure product quality and stability. At the same time, we should try to shorten the delivery cycle to meet the increasingly shortening of the construction cycle. ④ To continuously improve the management system of sales department and improve the cooperation and cooperation with chemical design and construction department to ensure the accuracy of ordering and ensure the quality of the project. Some valve companies often in different parts of the country set up sales points, responsibilities partition. Projects in the design department are often trans-regional. Valve companies and the design department is the contact area, and when ordering another area, often resulting in some requirements can not be to the factory, ordering requirements do not meet the design requirements, affecting the quality of the project, so that corporate reputation damaged. This is obviously the internal coordination of the valve business sales department. ⑤ valve manufacturers to actively participate in the contracting project construction company, to participate in the subcontracting work, and engineering companies closer cooperation. Valve companies should learn to respond to the inquiry of the engineering company, invite public bidding, standardize their own standard behavior and improve the standard level, to learn more about chemical engineering company requirements in order to achieve better collaboration. Third, the imminent accession to the WTO, the valve business innovation, improve product quality and strengthen production management is the key to China's accession to the WTO, which is the chemical industry and valve manufacturing are a great test. The advent of foreign valve products, will lead to more intense competition in the domestic valve manufacturing industry. Valve companies only continue to innovate, and constantly improve product quality, and strengthen production management, good raw materials and product quality control, maintain good market reputation, to be invincible. Strengthening the cooperation with chemical engineering department or chemical engineering company is also an effective way for valve manufacturing industry to make itself in a position of utilizing in the international competition. I believe that China's valve manufacturing industry will have a better tomorrow. Fourth, the conclusion Chemical design industry in development, our hospital is also changing. In recent years, our hospital has achieved remarkable results in reform and has achieved good results in all aspects. With the advantages of traditional projects such as paint, titanium dioxide, water supply and drainage, etc., the hospital further expanded its business scope of phosphate fertilizer, methyl ethyl ketone, ammonia, urea, municipal environmental engineering, melamine, sodium vanadate, sulfuric acid, Magnetic materials and other aspects of the project advantages, the project situation is better. Welcome all the valve enterprises and the hospital to collaborate for our country to contribute to the construction of chemical projects.
