　　Plate flange is included in the standards of chemical industry, national standard flange, Mechanical Department flange, Japanese standard flange, German standard flange, American standard flange and marine flange. In the domestic industry, the most plate flange common pipeline is used, and the pressure is from 0.25 MPa to 4.0 MPa. 　　Plate flange, as its name implies, is a flange without neck. Insert the pipe directly into the flange for welding. Generally speaking, the inside diameter of the small-caliber flange is slightly larger than that of the tube by 1-1.5mm, leaving such a margin in order to make appropriate adjustments in the installation process. Large-caliber plate flanges still have more, because plate flanges with large caliber are inconvenient to keep. 　　Plate flange sealing surface is generally divided into two kinds: one is called FF surface, that is, full-plane flange, so to speak,  ASTM A312 TP304L DN150 Stainless Steel Plate Flange  is like a disc, with ...

　　Blind flange is a solid plate, or common steel plate, which is used to block pipeline equipment at the joint of two blind flanges. The blind flanges purpose is to test the pressure, leak and plug the pipeline of pipeline equipment. 　　The product pipeline size range is & frac12; "96", and the Blind flanges grade range is 150 Blind flange products use convex or circular tongue mortise to join the gasket surface. Blind flange products have two series A (MSS SP44) or B (API 605), which conform to ASME/ANSI B16.5 and B16.47 specifications. 　　The  ASTM A105 Class300 RF Carbon Steel Blind Flange  production process is mainly divided into forging, casting, cutting and rolling. 　　The casting Blind flanges has accurate shape and size, small workload and low cost, but has casting defects (pore, crack, inclusion); the inner structure of the casting is poor streamlined (if it is a cutting part, the streamlined is worse); 　　The advantages of castings Blind flanges are that th...

　　Threaded flange is a kind of non-welded flange, which processes the inner hole of flange into pipe threads and connects with threaded pipes. Compared with the flat welding flange or butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used in some pipelines where welding is not allowed. Alloy steel flange has enough strength, but it is not easy to weld, or the welding performance is not good, also can choose threaded flange. But when the temperature of the pipeline changes sharply or the temperature is higher than 20 ~45 ~C. We recommend not to use threaded flanges in order to avoid leakage. 　　There are two types of sealing surface of  High Quality Stainless Steel Threaded Flanges From Shengtian ,full plane and protruding surface. Considering the structural characteristics of threaded flange. Therefore,threaded flanges is not suitable for inflammable/explosive and highly hazardous occasions. Low nuclear pressure...

　　Weld neck flanges, mostly used in gas valves, natural gas pipelines and so on. Because  Weld neck flanges have a short neck can improve the flange stiffness and bearing capacity. 　　Flat plate welding flange is used for general medium. 　　Weld neck flanges is suitable for flammable, explosive, corrosive and toxic places.  ASME B16.5 SCH40 RF Stainless Steel Weld Neck Flange  sealing surface is protruding surface (RF). The sealing surface of Weld neck flanges with neck can choose protruding surface, concave-convex surface and mortise-groove surface. 　　Weld neck flanges have different structures, sealing effects and strength. 　　The main products of Hebei Shengtian pipe fittings are flange, elbow, elbow, three-way, four-way, big and small head, different diameter pipe,etc. They can also be customized according to customers'drawings. 　　At the same time, we constantly provide the production technology of products, constantly strengthen and improve the quality assuran...
