In the two decades of reform and opening up, China's economy has been developing rapidly. International exchanges and cooperation in the field of engineering construction have also been increasing. The form of general contract construction by engineering companies is now rising in our country and starting to go abroad. This requires us to understand as soon as possible , The use of many popular international work methods, valve procurement is one of them. In recent years, we have participated in many international tenders and have undertaken several foreign engineering contracting projects. A few years of practice, so that we have a preliminary understanding of the international procurement of valves, the following on our experience in these areas to discuss with you, the purpose is to enable fire experts understand the basic requirements of this approach and the basic elements in order to In the future work can make the two sides tacit cooperation, accelerate the pace to enter the international market. 1. The importance of the valve in the chemical plant Valve is one of the important components of the chemical pipeline, is to meet the process requirements, to ensure safe and smooth production must be set pipeline components. It is used to break the flow in the pipeline, regulate the flow or pressure of the pipeline, control the flow of the medium in the pipeline, and also for the purpose of protecting the pipeline or equipment safety. There are four characteristics of chemical valve: 1) Species, specifications and types: 2) The working conditions are complicated and harsh: 3) Its own structure is complicated and its technical requirements are high. Important status but also the weakest link in the pipeline equipment. These characteristics make the design selection, material selection and manufacturing very difficult, therefore, the valve selection (including type, material, form, etc.) is appropriate, the quality of the valve manufacturing process will directly affect the operation of the plant, and even endanger the factories and operators Life safety In addition, in all kinds of chemical, petrochemical, oil and gas installations, the pipeline material costs account for about 15% to 20% of the total project investment, and valves account for 40% to 50% of pipeline materials costs. Therefore, both from the perspective of use or from an economic point of view, the selection of valves procurement, will inevitably be highly valued by investors or contractors. 2. Valve quality problems and supply and demand situation As mentioned above, the importance of valve quality on the chemical plant is self-evident. As for the quality problems, the following is a brief introduction of a set of data: According to (1996), the Ministry of Labor analyzed the causes of 200 pressure pipe accidents: Pipeline problems 32.6% Direct quality problems of pipeline components 27.3% Installation problems 18% Design 11% Corrosion l0 .6 Completed Commissioning 0.5% This device is only an analysis of 200 pipeline accidents. In fact, a part of the quality problems has been corrected in the engine before installation. The direct quality problems of the pipeline components are estimated to be about 1/3, which shows that the quality of the pipeline components, including the valve, remains to be raised. In 1998, economists in our country announced that over 100% of the products were in the domestic market. l999 years of new projects also report: survey showed that supply and demand balance or oversupply of up to 99.9% of the products, indicating that our country has completely entered the buyer's market, the valve industry is no exception. In this form, the product sales can only be by *: First, the product must be of sufficient quality and reasonable price: Second, the pre-sale service must be of high quality, in the bidding process, to be able to quickly and accurately , According to the requirements of the purchaser (or inquiry side) should be related to the problems or documents. One of the first is dead, that is, you have no perfect technology, the valve does well, that hardware: the second point is living, that is, technical documents are norms, that is, software, the latter point of this second often Neglecting that "knowing our products will do the job," there is such a view or stop at this level that they will suffer a loss in participating in international competition just as if one was full of knowledge, that is, could not tell or nobody recognized it.
