The development trend of Haokun company's flange products in the future
Haokun company for the current standard of special material alloy flange stipulated by the guarantee conditions flange manufacturers according to the provisions of the current standard for inspection and ensure that the provisions of the standard, called the guarantee standard material. Assurance conditions are also divided into: special alloy flange basic guarantee conditions (also known as required guarantee conditions). Whether the customer is indicated in the contract. The inspection shall be carried out according to the standard provisions, and to ensure that the inspection results meet the requirements of the standard. Such as chemical composition, mechanical properties, size deviation, surface quality, flaw detection, water pressure experiment or flattening or expansion of the process performance experiments, are required conditions. Guarantee conditions of special alloy flange agreement: In addition to the basic guarantee conditions in the standard, there are still " according to the requirements of the demander, the guarantee conditions of the current standard of special alloy Flange production process characteristics: large flange products are completely made of welding products, no thread. The control of the original import and export trade is becoming more and more strong, and the difficulty of national standard flange enterprises in the import of raw materials is constantly increasing. The wide application of new materials in the production of national standard flange is an important direction for the development of national standard flange industry in the future. According to expert analysis, the future national standard flange production raw materials will mainly come from fast raw materials, recycled materials and other carbon steel materials, carbon steel material national standard flange will gradually take over most of the market share of real and real carbon steel national standard flange. At present, many enterprises and scientific research institutions have made many attempts to apply new materials in the production of national standard flange, and have had substantial results, in some specific national standard flange fields have been put into use.
