15CrMo III profiled flange

Shaped flanges are used as sealing and fastening connections, also known as profiled flanges. It has a wide range of applications in aerospace and large containers in the petroleum and chemical industries. Although the problem of processing capacity is not considered, for the profiled flange, due to its large size, the overall processing of the profiled flange is impossible due to transportation reasons, and must be processed by splitting.

Features:

Normally, the profiled flange is always machined into several arc segments. First, the blank is forged into a billet, then cold-bent into an arc, annealed after stress-relieving heat treatment, and then formed into a full circle on the vertical car to the shape and size of the design, and finally transported to the construction site, and then a number of arc groups Welded into a complete profiled flange and welded to the pressure vessel.

Since the nominal diameter of the container barrel of the profiled flange is different from the specific size represented by the nominal diameter of the pipe, the container flange and the pipe flange of the same nominal diameter are also different in size, and the two cannot be substituted for each other.

standard:

Production and implementation standards for profiled flanges: national standard, American standard, Japanese standard, German standard, Italian standard, Ministry of Chemical Industry Standard, Mechanical Department Standard, Pressure Vessel Standard.

The pressure grade, material and standard of the profiled flange have different characteristics and characteristics. They are used according to certain principles and methods in the use. They can be produced and processed according to the corresponding standards, ensuring good use value in use and effect. Profiled flange pressure rating: 0.6Mpa~32Mpa (150Lb~2500Lb)

Shaped flanges have different production standards in use and production. They are produced and used according to the corresponding standards, which can guarantee the use value and function of the profiled flanges in practice.
