API 6a Type 6B Flange Premium Standard Raw Materials?
Apart from joining pipes to form a piping system; one of the benefits of using the API 6A Type 6B Flange produced at our factory is that they are robust and are very durable. At Rajtilak Metal, all components manufactured by us such as the API 6A Type 6B Slip On Flange are from premium standard raw materials. Therefore the performance of this API 6B Flange Standard is top notch and is considered to be high cost performance by all our clients across the world. Further, these flanges are able to provide easy access for cleaning, inspection as well as for modification.
What Is API 6a Type 6B Flange?
The slip on raised carbon steel API 6A Type 6B Flange or SORF, is typically produced with the inner diameter of the flange being slightly bigger in comparison to the outside diameter of the pipe. The API 6A Type 6B Flange could also be a ring or a plate, which would form a rim at the end of a pipe, when the flange has been fastened to the pipe. Often referred to as a raised type of flange, the gasket of the API 6A Type 6B Flange slip on raised one has been raised above the bolting circle face.
What Main Purpose Of API 6a 6B Flange?
The main purpose of the API 6a 6B Flange is the distribution of the heaviness or load on the smaller gasket area. Additionally, the slip on raised CS API 6A Type 6B Flange aids in up surging the repression competence of this joint. Besides having the Api 6a Type 6b Flange in various tolerances, grades, size , specification and thickness in stock, we also manufacture these api 6a type 6b flange dimensions as per the details or customizations as required by our clients.
