工业冲压弯头的磨损一直是影响文明生产的一个因素， 随着科学技术不断发展，材料也不断创新，相继出现铸石、铸钢、 合金、离心浇注复合陶瓷等材料。其中管道内衬氧化铝陶瓷以其高耐磨性、高硬度、耐氧化、耐腐蚀性好和极高的耐高低温强度性能,已成为一种应用广泛耐磨材料，占据了世界特种陶瓷市场份额(耐磨材料)的80%左右。
From the current domestic steel pressing elbow operation of the market point of view, transaction prices have been rising into the upstream channel of inertia, on the current market environment and operating conditions, the short period of time the price still has the possibility to continue to rise. At the same time we also found upstream of the original contract price of the fuel market, there may be stainless steel stamping prices pulled elbow, rebounded.
Press elbow resistance of air, steam, water and other corrosive medium and weak acid, alkali, salt and other chemical attack by corrosive medium steel. Practice, often the weak corrosion resistance as stainless steel corrosion medium on quality, and resistance to chemical media will be referred to as acid-resistant steel corrosion of steel. Since both the differences in chemical composition, the former does not necessarily medium chemical corrosion resistance, while the latter generally has a stainless steel sex.
Domestic stainless steel stamping elbow in 2009 will be forced to enter the contraction of production, but the high investment growth will allow further expansion of production capacity, stainless steel stamping elbow enterprises, in 2009 was a very painful and repressed the year, if the cost of raw materials can be significantly decreased, but also ease some pressure on steel prices, is nothing but the operating rate declined.
Industry Press elbow wear is always a safe and civilized production of a factor, with the continuous development of science and technology, materials are also innovative, one after another cast stone, cast steel, alloy, centrifugal casting composite ceramic materials.Alumina ceramic lined pipe in which its high wear resistance, high hardness, oxidation resistance, good corrosion resistance and high resistance to high temperature strength properties, has become a most widely used wear resistant materials, special ceramics occupy the world market share (resistant materials) about 80%.
Overseas, the industrial enterprises in general to do with wear-resistant ceramic lining wear, including Kyocera (KYOCERA), Kyushu, and the German BMW and other well-known industrial enterprises are making use of high alumina ceramic liner and wear parts.
English press that is seamless elbow ELBOW. Abbreviated as E.
Said common methods such as:
(1) 45E: 45 degree elbow
(2) 90E (L): 90 ° long radius elbow
(3) 90E (S): 90 ° short radius elbow
(4) 90E (L) R: 90 degrees long radius Reducing elbow
(5) 180E (L): 180 ° long radius elbow
(6) 180E (S): 180 ° short radius elbow
