Hebei production PN1.0 316L stainless steel welded flange, good quality and low price, long-term product PN1.0 316L stainless steel flat welding flange the Hongyuan tube industry: flat welding flange, blind flange, socket flange, with a diameter Flange Contact: Wang Shan 15,922,054,164 QQ: 1,494,092,364 and to push the system, pressing, forging, casting and other production methods can be divided into. 3. Manufacturing standards divided into the GB electricity standard, the ship standard of standard water standard, American standard, German standard, Japanese standard, the Russian standard, such as raised face (RF), concave (FM), convex (M) , tongue and the surface (T), the groove surface (G), the whole plane (FF). With neck flat welding flange diameter range: DN10 ~ DN600 Scope: PN Series PN2.5 ~~ PN40; Class Series Class150 ~ Class1500 flange material: carbon steel, Luo molybdenum steel 304,316,304 L, 316L, 321,347, CF8C. Manufacturing process: forging. Advantages: with neck flat welding flanges are welded flange, because there is a short-necked, thereby increasing the strength of the flange improved flange bearing efforts. It can be used in higher pressure pipelines. Disadvantages: more plate welded flange higher cost, due to the characteristics of its shape more easily bump in transit welding flange pressure range, the use of welded flange GD87-0506 flat welding flanges, welded flange the pressure, PN1.0 PN0.6 PN0.25 the company has advanced production lines, high production, low pressure elbow pipe reducer, tees, elbows, flanges and pipe factory Chemical Design and preparation of professional manufacturers. At the same time, the company also produces wear-resistant, anti-corrosion, insulation pipes, soda, pipe supports and hangers, as well as power plant accessories and other products. Is widely used in petroleum, chemical, electric power, construction, metallurgy, water conservancy and other large-scale projects.
