In order to ensure that the flange forgings have the dimensional accuracy and mechanical properties required by the design, the quality of the forgings must be controlled, that is, the entire production process from selecting raw materials to post-forging heat treatment must be controlled to ens ...

A carbon steel butt weld flange refers to a flange with a neck that is butt welded to the pipe.It is a kind of disc-shaped part used in pairs,and the most common type of flange in piping work that is mainly used for the connection of pipelines.When installing, the two flanges are sealed and then ...

API 6A standard is developed for the American Petroleum Institute. The API 6A specification shares many characteristics with ANSI/ASME flanges. Despite being dimensionally similar, their minimal design requirements for operating pressure begin in the 2000#. Certain jobs require the use of pressu ...

Both the AWWA and ANSI have thorough standards for flanges, and the two standards are different in several ways. AWWA standards provide flange properties intended for potable water use only. In contrast, ANSI standards are aimed at industrial flange applications. For example, AWWA flange ratings ...

AWWA means American Water Works Association.AWWA C207 stands for Steel Pipe Flanges for Waterworks Service- Sizes 4 In. Through 144 In. (100 mm Through 3,600 mm). This standard describes ring-type slip-on flanges and blind flanges. The flange pressure limits and the tables that describe them are ...

Flanges can either be forged or cast. Both manufacturing methods have their advantages and disadvantages, depending on the application you have in mind for your flange. Haihao Group primarily deal with forged flanges due to the outdated nature and lower standard of quality of cast flanges. Below ...

ASME B16.5 has endorsed the design of long welding neck flange (LWN),which is also known as straight hub welding flange. The long weld neck flange is constructed by two sections: the upper section is a heavy-wall barrel, whilst the lower section is a disc-like plate flange with all dimensions co ...

Large size flange is one of the flanges,which is widely used and popularized in the machinery industry,and has been well received and favored by users. Rolled flanges have a wide range of uses, and the scope of use is determined according to different characteristics. They are mostly used when t ...

Hot rolling and cold rolling are both forming processes of section steel or steel plate, and they have a great influence on the structure and properties of steel. Do you know what is the difference between them? As a professional supplier engaged in the steel industry for many years, let’s ...

As a professional flange supplier, let’s talk about the rolling process of ring forgings today. The rolling process of ring forgings can be classified according to the following methods: 1. According to the different compression deformation directions of the ring during the rolling process ...

Rolling flange processing technology: The middle plate is first cut into suitable slivers, and the length of the sliver is determined according to the specifications of the large flange. Then, the ring is rolled into a circle, and the joint is welded firmly with the electrode. Then use the press ...

The rolled flange is cut into slats by the middle plate, and then rolled into a round welded joint and then processed by a flattening process. The coil is made up of cold and hot coils. After processing into a circle, the water line, bolt holes, and stops are processed. This is generally a large ...
