Large diameter Q235B spiral steel pipe manufacturer for underground drainage

[Steel pipe sales phone number: (same as WeChat) Manager Zhang] On the whole, domestic steel prices have begun to weaken, with a magnitude of 0.0 yuan. Futures surged higher and fell back, with steel billets falling from yuan to yuan for two consecutive days. The expectations of Jinjiu have been disappointed, and the overall operations of merchants are mostly cautious. The decline in steel prices is obvious today. From a macro perspective, the total social inventories of major categories of steel products in cities across the country continued to rise month-on-month, with wire rod and rebar inventories still seeing a larger increase. Among them, the total steel market inventory was 10,000 tons, an increase of 0.000 tons from the previous month, an increase of .%. The port inventory was 10,000 tons, an increase of .000 tons from the previous month, an increase of %. Inventory pressure is obvious. &/& &&Anti-corrosion steel pipe polyethylene three-layer structural protective layer, also known as three-layer, is an advanced anti-corrosion technology introduced from abroad in recent years. Its full name is fused epoxy/extruded polyethylene structural protective layer. The structure consists of the following three layers: the bottom layer is fused epoxy (&&), the middle layer is adhesive (&), and the surface layer is extruded polyethylene (approximately) . The total thickness of the protective layer is approximately... In the three-layer structure, the main function of the sintered epoxy powder coating is to form a continuous coating film, directly bonded to the surface of the steel pipe, with good chemical corrosion resistance and cathodic stripping resistance and the activity of the adhesive in the middle layer The group reaction forms a chemical bond, ensuring that the overall anti-corrosion layer has good adhesion at higher temperatures. &/&
&&With the implementation of new traffic regulations for truck transportation, the transportation cost of steel has increased significantly. However, the phenomenon of no or few vehicles in the steel city is relatively common, which affects the speed of resource delivery. Subsequently, the finished steel products The sales price has also been increased accordingly. Driven by the rising costs, welded pipe quotations in various places have rebounded significantly. Today, the prices of many varieties in the steel market have retreated. In addition, the long holiday is coming, traders are more cautious in their operations and more conservative in purchasing goods. For the post-holiday market, although the Silver Ten is about to enter, the market as a whole lacks confidence in the monthly market as the Gold Nine market has not materialized.

&&With the continuous growth of crude steel production, the supply of resources in the domestic market has also continued to increase, and the social inventory of steel has continued to rise. With the pressure of oversupply in the domestic steel market emerging, steel prices are expected to maintain a volatile downward trend in the later period. Since late March, steel prices have continued to fall and raw material prices have continued to rise, making life increasingly difficult for steel companies. At present, there are already listed steel companies that expect their net profits to decline year-on-year in the third quarter of this year. As the highlight of steel demand, the start of real estate projects will also directly affect the steel market. Information analysts said that due to the tightening of financing channels for listed real estate companies, the release of steel demand in the fourth quarter will be restricted to a certain extent, which has also pushed steel prices downward in disguise. &/&
&&Anti-corrosion steel pipe for drinking water This product is a chemically reactive coating and is packaged in two components. Component A is resin and initiator, and Component B is active monomer and catalyst. Therefore, before use, the two components must be weighed according to the prescribed important proportions, mixed and stirred evenly, and cured according to the prescribed time before construction. The cured paint should be used up within dh hours to avoid cementation and waste. . The ratio is as follows: primer, component A: component B = barrel. Please strictly follow the required ratio (or apply according to the ratio notified by the manufacturer at the time) of topcoat, component A: component B = barrel. &/&
&&Steel pipe outer and inner sintered epoxy anti-corrosion steel pipe is an upgraded product based on the outer single-layer polyethylene inner epoxy composite steel pipe. It is currently the most advanced form of steel pipe anti-corrosion for buried long-distance pipelines. It is a fourth-generation new anti-corrosion production line for large-diameter pipelines independently developed by Weifang Dongfang Steel Pipe. The outer wall adopts the thermal fusion winding process, and the bottom epoxy resin, the middle layer adhesive, and the outer polyethylene form a three-layer anti-corrosion layer. The inner wall adopts thermal fusion winding technology. In the anti-corrosion method of spraying epoxy powder, the powder is heated and sintered at high temperature and then evenly coated on the surface of the pipe body to form a steel-plastic alloy layer, referred to as steel pipe. &/&
&&Today, the domestic steel market is stable and fluctuating. In some markets, quotations have been adjusted back due to the fall in steel billet and futures prices, but there is still no obvious sign of improvement in transactions. Enthusiasm for rising steel prices was quickly extinguished due to rising freight costs caused by pre-holiday stocking and new freight regulations. There are also rumors in some areas that penalties for exceeding transportation standards will be relaxed to ensure limited resource circulation. The National Development and Reform Commission held a meeting on matters related to ensuring the supply of coal for power generation and heating in Northeast China in winter, and may further require an increase in coal supply. Now, as we are about to enter the October holiday, how to digest the tens of thousands of tons of inventory that has risen for two consecutive months has become the biggest problem in the steel market. Faced with the complex supply and demand situation, the market is far from optimistic about rebounding.
