What are the characteristics of ductile iron pipe

2013-11-26


By the analysis of the steel market can be seen ductile iron pipe price trend. Due to changes in raw materials led the overall operation of the hub . Thread the wire increases with the level of inventory , the ability to quickly downstream demand is still an important issue market , short-term contradiction. Overall, the market showed no significantly reduced prices , mainly dropping slightly based. Plate , the main factor is the impact of rising inventories and sales of greasy , social stock show growth trend as a whole , especially in Shanghai to reach the amount of inventory days. Market pressures increase . Festival terminal stocking behavior is too short , the domestic raw materials ?
At present, the general situation of the overall turnover of iron powder market , supply and demand sides looked mood strong , stable market price of imported ore , poor turnover . With the advent of ductile iron pipe demand season , ductile cast iron pipe steel prices began to rise, steel consumption in corporate earnings improved significantly reduce production maintenance , steel production release is also synchronized to accelerate , Steel City destocking or under pressure. But after the holiday release downstream demand or volume , water conservancy and hydropower and other rural foundation to build a substantial investment to start building , will boost demand for steel at a certain level . Estimated that steel prices will be late into the upstream channel.
In the market, how do we choose ductile iron pipe ? This is not just based on our needs for more time division is also based on the needs of our material . We ductile iron pipe manufacturer in here to introduce some simple ways . Because of these , there will certainly be more in accordance with manufacturers and experience . Ductile iron pipe is made ​​of cast iron , also called ductile iron pipe and cast iron pipe in the manufacturing methods and materials , there are many differences , it is not the same nature . Application of ductile iron pipe in the countryside is also very common for water conservation has an important role in rural ductile iron pipes are used to stop watering , were originally used to stop irrigation diversion canals and drains have many Central is leaking , and not only drains the impact on air traffic and is not beautiful, as the economy carried out , more and more people are pursuing the United States side, and in order to advocate for resource conservation , township enterprises have advocated ductile iron pipe drains & P activities in addition to lead , so usual in in the village we saw drains , and now are public ductile iron pipe water , and it did midway phenomenon of water , water will not be a wasted in vain .
Ductile iron pipe should have the following features: anti-corrosion, the main water supply pipeline project using pipe cement pipe , ductile iron pipe and steel pipe. Pipes system, ductile iron pipe strength gray Pipes and fittings , tube elongation gray iron ductile iron pipe arrives, corrosion resistance iron pipe is gray iron pipe times , life is good at using gray iron pipe , replace the performance of various performance cf . The traditional gray iron material more brittle , with a mechanical interface when not connected to the higher use of land often can not prevent the onset of bursting phenomena encountered geological conditions, the external load conditions change , easy to attack the pipe brittle fracture and produce leak , now simply exit the market.
