Wear elbow insulation performance to a certain degree of progress, but because the temperature of the reaction is not high (even no more than 1200 ℃), short reaction time, Jilin alloy elbow, alumina restore them still remain at a low temperature phase β-Al2O3 and not be able to convert to high-temperature phase α-Al2O3 (transition temperature exceeds 1300 ℃). With alumina, but the world of difference between the high temperature and low temperature phase of alumina with alumina in strength, hardness and density function. Because the response time is short, low temperature phase of alumina and iron centrifugal separation is not complete, resulting in the ceramic layer is not dense, loose particles, low hardness. 95 ceramic wear elbow lining paste, alumina content of not less than 95%, Fushun alloy elbow, and all high-temperature phase α-Al2O3, the sintering temperature up to 1670 ℃, ensure that the material quality. From a practical point of view the effect of wear, wear elbow durable time is more than five times the composite ceramic elbow. In addition, the entire boiler hanger bearing capacity, the steel elbow, elbow composite ceramics are by weight and thickness to win, and some wear elbow wall insulation more than 40 mm thick, the unit design perspective, no doubt to increase the weight hanger and shorten the service life. The current market price of insulation elbow: Alloy around 18,000 yuan per ton, cast elbow 13,000 yuan per ton, 17,000 yuan per ton composite elbow. These types of insulation elbow particularly heavy, they are based on weight to seek profits. That is, an alloy is twice the price of insulation elbow resistant ceramic elbow, elbow with an alloy of money, you can buy two wear-resistant ceramic elbow, elbow insulation has some in the actual sales market prices, can produce certain production efficiency, guaranteed to produce a certain role and value in practical work. Yanshan County Bo Yan Pipe Co., Ltd. is located in Yanshan County Industrial Development Zone. North of Beijing and Tianjin and Beijing-Shanghai railway to the east Bohai Sea, Tianjin Port, Weifang alloy elbow, State Road across the county superior geographical conditions, abundant local resources, for my company's development has laid a good foundation. Best-selling products, and exported to South Korea, Vietnam, Singapore, Malaysia and other countries. I used to pursue "science and technology first, gaining the upper hand, quality, customer supreme, credit first" business ideas, is willing to domestic and foreign users and sincere welcome customers to work together to create a better future. Welded steel elbow is hot pressing or forging molding of the elbow, which is directly connected in the form of elbow and pipe welding, butt welding elbow major manufacturing standards generally GB / T12459, GB / T13401, ASME B16.9, SH3408, SH3409, HG / T21635, HG / T21631, SY / T0510. Welded elbow generally have 45-degree elbow, 90 degree elbow, 180 degree elbow, materials are carbon steel, alloy steel and stainless steel. Welded elbow purposes: usually welded elbow is in the pipeline construction site welding, which is due to the different types of pipeline welding standards, alloy elbow, the need for on-site welding pipe welds according to grade. Elbow butt welds. Elbow welded construction operations after welding Completing rust or anti-corrosion treatment according to the actual situation or pipe the external environment, in order to avoid bend in the weld rust or corrosion, resulting in life is too short elbow. Alloy elbow _ _ Bo Yan Pipe Co., Ltd. Dalian alloy elbow by Yanshan County Bo rock pipe industry. Yanshan County Bo Yan Pipe Co., Ltd. (www.czbygy.com) Hebei Cangzhou, elbow leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
