Plate index on Friday fell 0.37 percent compared with the previous day. Up to 23 major markets nationwide panel 12 day average prices fell. 8mm plate average price over the previous day down 11 yuan / ton, including Tianjin, down 20 yuan / ton. 20mm plate average price over the previous day down 10 yuan / ton, including Guangzhou, down 40 yuan / ton. 20mm low alloy plate average price over the previous day down 11 yuan / ton, including Shanghai fell 30 yuan / ton. Shanghai plate overall trend is slightly lower on Friday, closing gradually stabilized. Sources from the steel mills, the north due to the recent arrival of Handan mandatory 50% proportion of varieties board orders, short-term market is expected to continue to increase the variety plate heavier, increasing the pressure on the market. Coupled with the recent arrival Pinggang are also many low-alloy-based, further contributed to this trend. After neighboring Jiangsu Province prices rebounded slightly after falling up to restore normal volume again, but the decline has been significantly narrowed. Shanghai's main market traders overall mentality marginally reply, a little part to play a positive role in the overall price. Hedging northern today basically stable, the mainstream in 2150 yuan / ton wandering, but the actual hedging clients still below normal. Wuhan market last week showed a larger plate prices, the overall weak market transactions, the current market demand in Wuhan difficult to pick up, shipping business situation has not significantly improved. Market reaction, Ping steel resources leading bargain, low-alloy plate the first to fall, with the fall mainly general board resources. Last week the market bargaining power in general, businesses offer low close run, Handan Iron and Steel, E-Steel, Tangshan Iron and Steel resources stocks are rising, Ping Steel centralized arrival, the overall stock market correction. Integrated expected, although short-term domestic plate market prices downward pattern is difficult to significantly improved, but further declines will gradually begin to narrow. News: On Friday, China Heavy an "important issues suspend" announcement triggered a ship sector collective surge. However, from the Chinese point of view Heavy bulletin issued today, the company intends to suspend the origin of power-related assets held overseas investments.

Sales Hotline: 13678715087 Chen (24 hours patiently look forward with you ......) ductile iron pipe Main profile: use the 18th over after adding cast iron ball agent, through high-speed centrifugal ductile iron casting machine into the pipe, called "ductile iron pipe" (Ductile Cast Iron Pipes), referred to as the tube, ductile iron pipe and ductile iron pipe and so on. Ductile iron pipe is a cast iron pipe. Requirements on the quality of the cast iron pipe ball grade control 1-3 (ball rate> 80%), and thus the mechanical properties of the material itself ductile iron pipe product warehouse to get a better improvement, with the nature of iron, steel performance. Annealed ductile iron pipe, the microstructure of ferrite and pearlite, good mechanical properties, excellent corrosion resistance, ductility is good, good sealing effect, easy to install, mainly used for municipal, industrial and mining water, gas , oil and so on. Ductile iron pipe performance standards: GB / T13295-2003 ISO2531 / 2003 GB / T 13295-2008 water and gas pipes Ductile iron pipes, fittings and accessories GB / T 17457-1998 ductile iron pipes - Centrifugal cement mortar lining - General requirements GB / T 17458-1998 ductile iron pipes - Centrifugal cement mortar lining ingredients fresh mortar test GB / T 17459-1998 ductile iron pipe bitumen coating GB / T 17456 ductile iron pipe outer spray zinc GB / T 17219-1998 life Mechanical properties of drinking water distribution equipment and protective materials safety evaluation criteria ductile iron pipe: minimum tensile strength: 420 / Mpa, minimum yield strength: 300 / Mpa, a minimum elongation of 7%. Basic diameter ductile iron pipe: Historical Introduction to DN80-DN2600 ductile iron pipe: 1947 British H.Morrogh find additional cerium in hypereutectic gray cast iron, and that the content at least 0.02wt%, spherical graphite. 1948 United States APGanganebin et al noted that the addition of magnesium in cast iron, followed by ferrosilicon bred, when the residual magnesium is greater than 0.04wt%, the resulting spherical graphite. Since then, we began a large-scale industrial production of ductile iron. Use the history of ductile iron pipe dates back to 1668 suburbs of Paris from the Seine to Versailles audience about 21.14Km water pipelines, the 300-year passage of time, except for some maintenance and replacement of pipes and fittings, the body is still in use. Situation and Prospects of ductile iron pipe of ductile iron pipe industry started in the early 1990s, the strong support of the Association of Chinese urban water supply under rapid development, after nearly 20 years of practice to use, its safety, practicality has been Water industry generally recognized, in 2008 domestic production has reached 2.2 million tons, 11 times in 1990. Since China is a national shortage of water resources, water city as more than 600 cities in more than 200 serious water shortages, water supply and saving the ascendant career, ductile iron pipe has broad prospects for development. Ductile iron pipe selection advice: Choose one pair of ductile iron pipe should be laid according to the specific situation, select the interface in the form of a straight pipe and fittings. 2 rubber ring is recommended to use EPDM ring. 3 coating selection: According to internal use and external conditions and select the appropriate coating. Within the existing coating is an epoxy resin, a polyurethane coating inside and outside, PE film coating and other new products, ductile iron pipe, should be selected to learn more about its properties. Main Products Pipe categories: pipe, galvanized pipe, the huge pipe, stand pipe, spiral pipe, seamless tube; profile categories: angle, channel, I-beam, miners, steel, rail steel, H section steel; thread steel, wire, mold steel and accessories. Plate type: Plate, a plate, checkered plate, sheet, Cape plate, cold rolled plate, etc; Contact: Chen 13,678,715,087 (Under-steel sales business, good business, answer all the questions, including your satisfaction) Email: 38,756,527 @ qq.com Company Website: www.yngantao.com Address: Kunming Business Building, Room 3024 New Port Economic Development Zone stingy steel logistics
