The following is a detailed introduction to the butt-welding flange: 1. **Definition**: The butt-welding flange is a type of pipe fitting, which refers to a flange with a neck and a transition of a circular pipe, and is connected to the pipe by butt welding. 2. **Features**: - **Good Sealing Performance**: It adopts circumferential welds and welds the inside and outside of the pipe. The welds are located on both the inside and outside of the flange, enabling it to withstand higher pressure and temperature changes, and providing reliable sealing. - **High Strength**: With the design of a prominent long neck, it enhances the rigidity and strength, can bear greater pressure and stress, and is suitable for high-pressure and large-diameter pipelines. - **Not Easy to Deform**: Due to the reasonable structural design, coupled with processing techniques such as forging, the material has a high density and strong mechanical properties, and is not prone to deformation under harsh working conditions such as high temperature and high pressure. 3. **Scope of Application**: It is suitable for pipelines with large fluctuations in pressure or temperature, or for high-temperature, high-pressure and low-temperature pipelines. Generally, it is used for the connection of pipelines and valves with a PN greater than 2.5MPa, and is also used for pipelines transporting expensive, flammable and explosive media. 4. **Classification**: According to the production process, it can be divided into types such as forging, casting, and machining from medium plates. 5. **Production Process**: It is mainly divided into four types: forging, casting, cutting and rolling. Forged flanges have a dense structure and excellent mechanical properties; cast flanges have accurate blank dimensions and low costs, but may have defects. 6. **Production Standards**: Commonly used standards include the standards of the Ministry of Chemical Industry HG/T20592-2009, HG/T20615-2009, and the national standard GB/T9115.1-2000, etc. 7. **Materials**: Common materials include WCB (carbon steel), LCB (low-temperature carbon steel), CF8M (316 stainless steel), CF8 (304 stainless steel), M35-1 (Monel), etc. 8. **Marking**: Marking is carried out according to the nominal diameter, nominal pressure, code of the sealing surface form, code of the matched steel pipe series and the standard number. For example, a convex-face butt-welding steel pipe flange with a nominal diameter of 80mm and a nominal pressure of 4.0MPa (matched with metric pipes) is marked as: Flange DN80 - PN40 M (Series 2) GB/T9115.2-2000.
