Recently, the steel market from the perspective of the operational state of the country , the nation's major cities pipe prices steady overall , there are a few areas fell slightly . Shanghai , Hangzhou, Nanjing , Beijing , Tianjin, Wuhan , Shenyang, Changchun and other cities 1.5 inch × 3.25mm Longitudinal prices are steady , the price of 3490 yuan / ton to 3,930 yuan / ton , only Tangshan and Guangzhou the price decline , down 30 yuan / ton and 50 yuan / ton , respectively , the price of 3410 yuan / ton, 3900 yuan / ton , the average price in major markets was 3701 yuan / ton , down 5 yuan / ton. 4 inch × 3.75mm ERW price situation is also true in major cities , Tangshan and Guangzhou market prices fell by 30 yuan / ton and 50 yuan / ton , the national average price for 3695 yuan / ton, down $ 5 / tons.
In an interview with " China Metallurgical News" reporter found in operators that reform bonuses nowadays new urbanization and other aspects of the release , including pipeline replacement and new towns , became a significant opportunity for future network -related industries .
Urban infrastructure in pipeline construction bright scene
The new central leadership of the urban pipe network construction and transformation of very great importance , at a State Council executive meeting in August of this year , Premier Li Keqiang in the deployment to strengthen the construction of urban infrastructure , specifically made to strengthen several key task of urban infrastructure . First , strengthening of municipal underground pipe network construction and transformation , improve the urban water supply facilities , improve urban waterlogging capabilities ; Second, the strengthening of sewage and garbage disposal and recycling facilities, to five- end , urban sewage and garbage -free harmful treatment rate of about 85 % and 90 %, respectively ; Third, strengthening the gas, heating the old pipe network transformation . By 2015, the town completed 80,000 kilometers of gas and nearly 100,000 kilometers north of old heating district heating pipe network transformation task ; fourth is to strengthen the ecological environment , improve urban green flood drainage, groundwater recharge and other functions.
After the meeting , the municipal governments to step up implementation of the objectives of the underground pipe network construction conference raised a large number of urban pipeline construction started.
Drainage and sewage pipe network construction hot. Recently, invest 95.62 million yuan in Yunnan Pu'er City transformation drainage network construction starts, at present, " the main city of Pu'er storm sewer project" feasibility study report has been published, Yunnan Province Development and Reform Commission has approved, is expected to begin next year on the Puer City of rainwater and sewage pipe network synchronization transformation, and the expected duration of three years.
Tianjin will further increase the sewage treatment plant and associated pipeline network construction, improve sewage treatment factory network system , expanding the scope of the collection of water , sewage treatment and gradually make up the blank area , while strengthening the sewage treatment industry management ; plan new ( expanded) construction of sewage treatment plant 64 , the new sewage treatment capacity of 517,000 tons , 1,479 km pipe network construction , to ensure that by 2016 , the city's urban sewage treatment rate from the current 88 % to 95% . Additionally , the Fujian provincial government said it plans to transformation of more than 1200 kilometers of new urban drainage ( sewage ) pipe network , including the new storm water pipe network 540 km , 660 km sewer network ( including rain water and sewage separate transform 130 km ) . Meanwhile, the obsolete pipes and water leakage seriously affect the safety of the old pipe network will be fully eliminated, the new transformation of more than 1200 kilometers of water supply pipe network.
New and old gas pipe network transformation have started. Fujian Province plans to build more than 1,000 kilometers transform the gas pipeline network , which 300 km West-East Gas Trunk Line Fujian three sections, 200 km Fujian liquefied natural gas utilization project Phase II pipeline , construction of urban gas pipeline 500 km , 45 km over 15 years of renovation old gas pipe network. The next few years , Guangxi will invest about 61 billion yuan , accelerate the construction of natural gas into the Guangxi regional , prefecture-level city specifically for the pipeline , county extension , urban pipe network and ancillary facilities , build multi- gas source, multi-level, and a national network of safe and stable supply pattern. Recently, Shaanxi Danfeng natural gas main pipeline under construction , with a total investment of 150 million yuan, laying 42.5 km long natural gas transmission main channel.
Urban pipeline construction or pulling pipe, cast pipe demand
Pipeline construction from the city and start the case all over the scale of investment point of view , one large-scale investment , the pipeline project is more than two or three lines long pipeline , the construction of four is fast . Many cities from the current bidding construction projects can be seen in the larger welded steel , cast steel pipe demand .
A number of projects in the tender clearly Chengshiguanwang using welded steel and cast steel . Such as steel procurement Tangshan Yutian County town gas pipeline construction , the clear requirements spiral welded steel pipe supplier and Maintenance , materials for L360MB, specifications for 508mm × 8mm, a length of 10.5 kilometers, is also required to strengthen the level 3PE anti -corrosion ; Tangshan thermal Engineering Corporation in 2013 with the road network construction materials needed for heating engineering procurement tender notice, clearly defined procurement DN1400 spiral welded steel pipe.
Pipeline industry for the problems in urban research and analysis found that storm drain pipe aging phenomenon occurs with the tube material has great relevance. Domestic pipelines often appear suddenly a city storm drain , mainly using the original diameter of 300mm PE pipe , the pipe section is now PE pipe diameter of 400mm replace ductile iron pipe , storm drain issues have been a better solution . Thus , the use of spiral welded steel pipe and ductile iron pipe will significantly increase in the future pipeline construction project in the city . In addition, some cities are now underground drains have begun to adopt a strong anti-corrosion properties of spiral steel pipe, such as 2.8 meters in diameter large diameter spiral pipe corrosion .
As the State Council meeting proposed to improve the urban water supply facilities , sewage facilities to strengthen the implementation of the task , the demand for this type of steel will be significantly increased. Report on the agency 's analysis shows that China's total investment during the second five sewer network will reach 244.3 billion yuan . Data shows that the laying of underground pipe diameter 1200 mm diameter are mostly mixed steel drainage channels , its overall cost of 1.6 million yuan per kilometer ; diameter of 2000 mm of steel-concrete sewer costs to reach about 400 million per kilometer . In addition, the construction of urban pipeline also requires a lot of steel pipes of various materials , such as low pressure fluid galvanized welded steel pipe , low pressure fluid with a large diameter welded steel pipe , have been widely used for conveying water , gas, air and other generally lower pressure fluid.
