由西安重型机械研究所设计,与上海高桥无缝弯头厂联合制造的1250/850/850胀形液压机,主要用于碳钢、不锈钢和有色金属三通管件的生产。经过一年多的生产考验,已生产了30余种同径异径三通,产品质量高,压机性能良好,于1991年10月23日,在上海通过机电部组织的技术鉴定。鉴定认为,“采用镦挤与胀形复合成型先进工艺生产的三通接头,几何形状、尺寸精度和管壁均符合要求,各项技术指标均达到了美国ANSIB16.9和德国DIN2615及沪Q/NJ594—90标准。产品质量居国内领先地位,并已成功地用于石化、船舶、冶金、电力和军工等部门,可替代进口产
Designed by Xi’an Heavy Machinery Research Institute and co-manufactured by Shanghai Takahashi Seamless Elbow Plant, the 1250/850/850 bulging hydraulic press is mainly used for the production of carbon steel, stainless steel and non-ferrous metal tee fittings. After more than a year of production test, has produced more than 30 with the same diameter Reducing Tee, high-quality products, the press performance is good, in October 23, 1991, in Shanghai through the Ministry of Electrical and Mechanical Services Department of technical appraisal. Identification that "the use of upsetting extrusion and bulging shape of the three-way joint production of advanced technology, geometry, dimensional accuracy and wall are in line with the requirements of the technical indicators have reached the United States ANSIB16.9 and Germany DIN2615 and Shanghai Q / NJ594-90 standard. Product quality Habitat leading domestic and has been successfully used in petrochemical, marine, metallurgical, electric and military sectors, can replace imported products
