120m~3锥形露天啤酒发酵罐,是七十年代以后西欧兴起的先进发酵工艺的啤酒酿造设备,它属第1类压力容器。主体材料厚度分别为4mm、5mm、6mm的奥氏体不锈钢板。罐体直径4m、长1 6m。内表面焊缝加强高全部磨平,光洁度▽7。鉴于其外径大、壁厚薄、刚度小、易变形等特点,在设计及制造工艺方面必须充分考虑其难度,如尽量减少焊缝数量、合理构焊接程序、预防焊后变形等措施。尤其是采用在国内应用不多而在酉欧已普遍采用的氩气保护双面焊接工艺。为此,制造厂选用了适合于大型啤酒罐的长、宽尺寸大板料,采用钨极手工(双面)氩弧焊接方法。以其气体保护稳
120m ~ 3 conical beer tank fermentation, is the seventies after the rise of Western Europe advanced fermentation process beer brewing equipment, it is a Class 1 pressure vessel. The main material thickness of 4mm, 5mm, 6mm austenitic stainless steel. Tank diameter 4m, length 16m. Inner surface of the weld to enhance all the polished, finish ▽ 7. In view of its large outside diameter, thin wall, low stiffness and easy deformation, the design and manufacturing process must take full account of its difficulty, such as minimizing the number of welds, welding process and reasonable measures to prevent deformation after welding and other measures. In particular, the application of argon in the country has not been widely used in Europe has been widely used to protect the double-sided welding process. To this end, the manufacturer chose a large, long, large-size sheet suitable for large beer cans, using a tungsten manual (double-sided) argon arc welding method. Stable with its gas protection
