[10th Focus] As an industry listed company with super hard materials industry development leader and barometer, the company has released interim results recently. Compared with the macroeconomics, the operating conditions of these companies can be described as bright in the first half of 2011: The Yellow River Cyclone, Henan Diamond, Boshen Tools, and Sifangda achieved substantial profit growth. According to estimates by securities forecasting institutions, the development of the industry will continue for a long time, benefiting from the expansion of downstream industries, the improvement of the European and American economies, and the unique advantages in the new energy field. News link: super hard materials or the next "graphene" leading stocks can grow at a high rate http:// [macro window] The economic stimulus plan started due to the financial crisis In 2011, it brought serious sequelae, inflation, shrinking manufacturing industry, difficulties in operating SMEs, and weak domestic consumption. Due to cost pressures and the break of the capital chain caused by bank interest rate hikes, the profit rate of enterprises has been running below negative for a long time, leading to the collapse of enterprises in Guangdong and Zhejiang. How to conceal wealth in the people, the country retreats the people, effectively alleviates the burden on enterprises and becomes the focus of the government. News link: Guangdong semi-annual report responds to the collapse of half of the SMEs face losses. The current difficulty of SMEs surpasses the 2008 SME support policy will be introduced in the second half of the [industry chain] How the industry develops in the second half of the year depends on the changes in demand of downstream industries, Xiaobian For you to sort out some of the downstream industry development trends, for reference only news links: China Steel Association: the steel industry will face greater difficulties in the second half of the year, the top ten experts comment: the ceramics industry in the second half or turn to the downturn global tool market in the future 5 Yearly steady growth http:// Machine tool "Twelfth Five-Year" forecast: annual growth rate will exceed 10% 2011 second quarter PV market trend analysis [editing vision] News link: The third round of the 16th National Conference on Abrasive Technology Conference notified Element Six to launch a new CVD diamond thermal management product http:// Anti-dumping zeroing practice for diamond saw blades in China Was included in the WTO dispute case http://

Rubber Joint

Flexible rubber soft joint is also called rubber joint, rubber flexible joint, soft joint, shock absorber, pipeline shock absorber, shock absorber throat, etc. It is a kind of high elasticity, high air tightness, medium resistance and weather resistance. The pipe joint is a hollow rubber product that acts as a flexible connection between metal pipes
Rubber soft joint products utilize the advantages of rubber's elasticity, high air tightness, medium resistance, weather resistance and radiation resistance. High pressure, high temperature mold vulcanization. It has high internal density, can withstand high pressure, and has good elastic deformation effect. Shock absorption, noise reduction, lightweight, non-toxic.
According to the shape, it is divided into: concentric and same diameter, concentric reducer, eccentric reducer.
According to the structure, it is divided into: single sphere, double sphere, elbow sphere.
According to the connection form, it is divided into: flange connection, threaded connection, threaded pipe flange connection.
Flange for connecting rubber joint: DIN BS ANSI JIS standard
Working pressure: 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa
Working temperature: -40 degrees to 80 degrees (also can process high temperature resistant rubber soft joints)
Material of main parts
Ball body: natural rubber, neoprene, butyl rubber, nitrile rubber, fluorine rubber, EPDM
Inner and outer lining: natural rubber, neoprene, butyl rubber, nitrile rubber, fluororubber, EPDM, PTFE
Main frame: Nylon cord
Booster ring: multi-strand copper-plated steel wire
Flanges: Cast, Forged Carbon Steel (Q235), Stainless Steel (201, 304, 316, 321), Plastic (PVC, PPC)
The flexible rubber soft joint solves the problem of different diameters when connecting metal pipes, and also has the effect of shock absorption and noise reduction, which can save pipe installation parts and save costs. It has the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect, and convenient installation. It is used in connection with pumps and Valves, pipelines with large vibration, and pipelines with frequent changes in cold and heat.
Rubber soft joint products have high pressure resistance, good elasticity (axial and lateral angular displacement), noise reduction, light weight, shock absorption, easy installation, flexible use, easy replacement and maintenance, and have acid resistance, alkali resistance, oil resistance, etc. Features.
Can be widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceuticals, petrochemicals, ships, pumps, compressors, fans and other pipeline systems. The ordinary type is used to transport air, compressed air, water, seawater, oil, acid, alkali, etc. at -15â„ƒ~120â„ƒ. The special type is used to transport the above-mentioned medium or oil, concentrated acid and alkali, and solid materials above -30â„ƒ~250â„ƒ.
Applicable media: sea water, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder.
The normal applicable medium for flexible rubber joints is ordinary water with a temperature of 0-60 Â°C. For special media such as oil, acid and alkali, high temperature and other corrosive and hard textures, the corresponding special-resistant material rubber joints should be selected. , and cannot be used blindly or generically.
When using or storing the flexible rubber joint, avoid high temperature, ozone, oil and acid-base environment. A sunshade frame should be built for pipes used outdoors or facing the sun and wind, and it is strictly forbidden to expose to the sun, rain, and wind erosion. The surface of the joint is strictly prohibited to be painted and wrapped with thermal insulation materials. Due to the aging problem of rubber products, it should be checked and replaced in time.
