The ZS-TDT90-254×1220/12000 steel pipe expansion machine developed by Tianshui Forging Machine Co., Ltd. is the first in China, filling the domestic gap, passing the provincial scientific and technological achievements appraisal, its technology has reached the international level, and won the 2007 Tianshui Technology. Progress first prize. The successful development of the machine marks the further establishment of the flagship status of Tianshui forging domestic pipe-making equipment, ending the situation that China's large straight seam submerged arc welded pipe production line completes its dependence on imports, making China the third after the United States and Germany. The country that produces steel pipe expansion machines.
Steel pipe expansion machine is one of the key equipments for large diameter straight seam submerged arc welded pipe production line. Due to high technical content, complicated production, high control precision and difficult processing, many domestic research institutions and enterprises have not achieved success for many years. At present, only two companies, such as Germany and the United States, can produce the equipment. The price is extremely expensive. The total price of a single piece of equipment has reached 120 million yuan. The steel pipe expansion machines in the three straight seam submerged arc welded pipe production lines that have been built in China are all imported from Meer, Germany. As one of the key equipments in the production line, the price accounts for about 30% of the entire production line, and it plays a pivotal position in the pipeline production line.
After years of in-depth research on the expansion process, Tianshui Forging Machine Co., Ltd., based on the summarization of the existing technology of foreign companies, has independently developed and produced ZS-TDT90-25.4×1220 with independent intellectual property rights. /12000 steel pipe expansion machine is mainly used for expansion and straightening of steel pipe. It eliminates the complex stress and deformation generated by steel pipe during forming, internal and external welding by expanding the diameter, and makes the geometrical accuracy of steel pipe meet the specified requirements. It can replace imported products. Its successful development has broken the monopoly of foreign companies in the international market, and the price of this equipment is only 1/5 of that of similar foreign products. The market prospect is very broad. On December 14, 2006, the aircraft was successfully inspected by Mexican users and successfully exported. It was approved by a new product and scientific and technological achievements appraisal team composed of well-known domestic experts. Now it is being carried out with three users including India, the United States and South Korea. After technical negotiation, after the contract is signed, it is estimated that the foreign exchange will be more than 8 million US dollars. It is expected to save more than 24 million US dollars per year.
