Large diameter flange fluctuates up and down with the price of iron ore

concave convex sealing surface, which is suitable for occasions with slightly higher pressure; Tenon and groove sealing surface is suitable for flammable, explosive, toxic media and high pressure occasions. Flange pipe fittings with different properties have good product performance in different fields. Different occasions and spaces will produce different effects. As of March 3, the iron ore inventory in Chinese ports has reached 130.1 million tons, breaking a new high. Generally speaking, when inventory is high, the market will fall. McKinsey, CEO of BHP Billiton, said that BHP Billiton, as the world's third largest iron ore producer, has observed in the short term, but there is an uncertain downside risk in the project land, because China's steel demand growth is not fast enough, and the high port inventory and increased low-cost supply sources have made it worse. 2. The exterior paint of the equipment is sprayed with plastic. Analysts predict that the price of iron ore will plummet by 30% or more in the second half of the year; Analysts at HSBC believe that iron ore prices will fall below production costs in the second quarter of 2017

large diameter flange is one of the flanges. In the machine, this kind of pressure is converted into jet mixing kinetic energy through a special nozzle. It is widely used and promoted in the mechanical industry, chemical industry, wind power industry and sewage treatment industry, and has been highly praised and favored by users. Large diameter flange has a wide range of uses. The production process is divided into rolling and forging, and the extra large one can only be rolled. The materials are carbon steel, stainless steel and alloy steel

common large-diameter flanges are flat welding flanges and butt welding flanges. There is no large diameter screw flange. In the actual production and sales, flat welding products account for a large proportion. The structure and application range of flat welded large-diameter flange and butt welded large-diameter flange are different, and the characteristics and advantages they can show will also be different. Therefore, when using them, they should be used in different ranges to ensure that the flange plays an important role. Large diameter flat welding flange has poor rigidity and is suitable for occasions with pressure P ≤ 4MPa; Butt welding flange, also known as high neck flange, is rigid and suitable for occasions with high pressure and temperature. There are three types of flange sealing surface: plane sealing surface, which is suitable for occasions with low pressure and non-toxic medium; Concave convex sealing surface, suitable for occasions with slightly higher pressure; Tenon and groove sealing surface is suitable for flammable, explosive, toxic media and high pressure occasions. Flange pipe fittings with different properties have good product performance in different fields. Different occasions and spaces will produce different effects. Large diameter flange will also fluctuate with the price of iron ore
