Lishui Drainage Pipe Manufacturer - Bridge Cast Iron Drainage Pipe Specification

Description :

　　Lishui Drain Pipe Manufacturer - Bridge Cast Iron Drain Pipe Specification: Bridge deck drain pipe, cast iron drain hole, bridge deck drainage pipe, extended circular drain pipe, etc. The main process is to first make a mold, then go through sand mold forming, casting, semi-finished product forming, sandblasting treatment, painting, and the finished product is out of the furnace. The reporter noticed that almost every pier wall has one of these drain pipes every 30 meters. The long white drainage pipe is tightly attached to the bridge pier wall, with the upper end connected to the sewer on the bridge and the lower end connected to the underground pipe network. Through this pipeline, the water on the bridge flows directly into the city's drainage system. Not only that, this design can also drain melted snow water in winter. Due to the special angle design, even if snow water flows in, it will not cause pipeline blockage. If there is a situation of icing at the end, sanitation workers can solve it with a little cleaning. Many customers often call to inquire about how to design the drainage holes on the bridge deck in a more reasonable way. Our company's technical director said that the distance of the installation varies depending on the slope. The slope of the bridge is greater than 2%, and a bridge drain hole needs to be installed every 13 meters. A slope of less than 2% needs to be set every 8 meters.Currently, the domestic steel market demand is lower than expected, and "power restrictions" will also affect the performance of terminal demand to a certain extent. This will have multiple impacts on the construction industry, with a decrease in the production of major building materials such as steel, cement, and glass; At the same time, power restrictions will also affect the development progress of real estate projects, prolong the material cycle, and thus affect the market demand for building materials. For the manufacturing industry, the impact of "power restrictions" is broader and deeper, with a greater and more significant impact on the demand for manufacturing related materials. This will significantly affect the usual steel demand in the manufacturing industry in the fourth quarter.

　　In November 2021, the prosperity of the steel industry fell from a high level and returned to a contraction range, indicating that the domestic steel market is gradually shifting from peak season to off-season. From the current situation, the actual downstream procurement demand for steel will show a downward trend, especially in key areas where power restrictions are a double-edged sword, which will have an impact on both supply and demand. Raw material prices will also return to rationality, and the cost support of the steel market will weaken in the later stage. Against the backdrop of weak supply and demand, the domestic steel market will oscillate around the cost line. Therefore, the Lange Steel Research Center predicts that the domestic steel market will experience a volatile adjustment in November 2021.
