What are the common specifications of 09CrCuSb acid-resistant steel pipe? First of all, the commonly used specifications of acid-resistant steel pipes are between 10-60mm,
such as 76/89108/114/-219mm, but these specifications need to be customized and are not available. 09CrCuSb (ND steel) steel is developed for the purposes of coal-fired boilers, oil-fired boilers; electric furnace heat exchange, smoke pipes, chimneys, boiler air preheaters, economizers, heat exchangers, condensing coolers, evaporators, etc. The hot-rolled steel sheet and steel pipe with excellent resistance to sulfuric acid dew point corrosion. Its excellent performance of sulfuric acid dew point corrosion resistance and very high cost performance, it is the best material that can completely replace stainless steel and surpass stainless steel (in terms of sulfuric acid dew point corrosion resistance). Energy saving, environmental protection and other "green" concepts and development policy orientation.
ND acid-resistant steel pipe commonly used specifications ND acid-resistant steel pipe information ND acid-resistant steel pipe market conditionsAdvantages: ND steel pipe , namely 09CrCuSb steel is the most ideal steel for "sulfuric acid low temperature dew point corrosion resistance" at home and abroad.
ND acid resistant steel pipe is widely used in the manufacture of economizers, air preheaters, heat Equipment such as exchangers and evaporators are used to resist dew point corrosion of sulfur-containing flue gas.
ND steel is also resistant to chloride ion corrosion. The main reference index of ND steel pipe (immersion in 50% H2SO4 solution at 70 degrees Celsius for 24 hours) is higher than that of carbon steel, similar steel imported from Japan, and stainless steel corrosion resistance.
The product has been widely praised after being used by major domestic refineries and manufacturing units. The carbon content in the steel is low, and the use effect is good.
Uses: Widely used in power plants and refineries to manufacture economizers, air preheater steel pipes, heat exchangers and evaporators that work in high-sulfur flue gas to resist condensation and corrosion of sulfur-containing flue gas.ND acid-resistant steel pipe commonly used specifications ND acid-resistant steel pipe information ND acid-resistant steel pipe market conditions
Market: Recently, ND tubes have been rising strongly. Upstream tube factories have frequently adjusted their prices, and downstream merchants have followed suit.
The continuous rise in current prices has made merchants worried about the price drop in the later period. With the increase in upstream prices, although the enthusiasm of the downstream to obtain goods has gradually increased, there is still a certain gap compared with last year.
The current price increase has gradually increased the cost pressure of end customers, so it is more cautious to buy goods and basically take them as needed. From the perspective of raw materials, although the bifocal series have fallen sharply recently, in terms of the market environment of ND tubes, the price will not rise frequently in late September, and it should maintain a steady upward movement on the eve of the end of September.
