Gasket and bolt are commonly used with flange,to protect the flange in the pipeline. 1.Gasket Gasket is especially important for the leakproofness of flange joint. The gasket is a compressible plate or ring used for sealing between two surfaces. Gasket materials are widely used to adapt to vario ...

Maybe you heard of flange class and flange schedule,sometimes confused what flange class and flange schedule is,are they the same? You maybe know a little about flange,flange class is a pressure-temperature rating that defines maximum allowable working pressure of the flange. Flange class is usu ...

There are hundreds of different types of stainless steel flanges on the market, which may be difficult to find the perfect metal for your application. In many purchasing processes, the cost of metals is the first consideration rather than the performance of metals, but this is wrong. In some cas ...

What is the difference between ASME B16.5 standard and ASME B16.47 standard? ASME B16.5 standard covers steel pipe flanges and flanged fittings from NPS ½” through NPS 24″ in pressure classes 150 to 2500. This includes pressure ratings, dimensions, tolerances, materials, marking, and ...

When producing slip on flanges, steel plates shall not be directly machined into neck flanges, and they shall be fabricated and processed by certain processes. Steel plates for slip-on flanges shall be ultrasonically inspected without delamination defects to ensure good quality and prevent perfo ...

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 ...
