DIN PN16 Ductile Iron Wide Range Pvc Pipe Flexible Joints Universal Flange Adapter
Product Introduction
The flange adapter is mainly composed of a valve body, a gland, a sealing ring and a bolt. The valve body and gland are usually made of carbon steel or ductile iron, and the sealing ring is sealed with EPDM rubber, which has good water tightness and air tightness. The supporting use of expansion joint and butterfly valve makes the angular displacement between the axial extension and the radial direction of the flange surface, and the position and angle compensate for the error of the pipeline flange, eliminate the internal stress of the pipeline caused by the temperature of the pipeline, and bring great convenience to the installation and maintenance of the pipeline.
Product Advantages
1. Interface standardization: The flange adapter adopts standard flange connection, which is interchangeable and easy to assemble and maintain.
2. A variety of materials are available: The flange adapter can be made of stainless steel, carbon steel, steel-plastic, and other materials to meet the transportation requirements of different media.
3. High strength: The flange adapter is usually molded by die-casting, which has high strength and durability and long service life.
4. Easy installation: The flange adapter is easy to disassemble and assemble, simple to install, and does not require special docking treatment, which reduces labor and time costs.

Technical requirements for flange adapters
1. The flange sealing surface should be correctly aligned (axial and radial), and the parallelism and alignment tolerance should be in accordance with the regulations.
2. Before tightening the bolt, the gap of the flange sealing surface should not be greater than 2 times the thickness of the gasket, and it should not be put in place with the help of external auxiliary tools, nor should the method of tightening the bolt be used to adjust the spacing of the flange or eliminate the deflection of the flange joint.
3. The bolt should be perpendicular to the flange and pass freely through the bolt hole, and the nut should be flat and pasted to the back of the flange.
4. The excessive installation deviation of the flange joint should be corrected before the gasket is loaded.
5. The size of the gasket should be consistent with the size of the flange, and it should be kept coaxial with the flange during installation to prevent blocking the medium flow channel.
