S nomi is one of the Largest Api 6A Flanges  Manufacturer in Kolkata, West Bengal, Bihar, Odisha, Jharkhand. Originally, all Api Companion Flanges that were related to pipe, became standard as threaded, weld neck and blind configurations. 

As equipment with integral flanges came to industries such as oilfield, standardization became necessary for the purpose of maintaining functional interchangeability between both the pipes and the Api 6A Flanges Dimensions Weld Neck. If you search quality of Api 6A Flanges Manufacture, then S Nomi is best choice for you.

From the late 1930’s, the American Petroleum Institute also referred to as the API had adopted the then ASA B16.5 flanges. 

For  the Api Weld Neck Flanges applications involving pressure classes –  720 psi and 960 psi, the API specified no changes to the ASA B16.5 Standard, using the 300 lb. and 400 lb. flanges respectively. 

But for the API 6B Integral Flange applications for pressure classes 2000, 3000, and 5000 psi, the API specified an increase in the requirement in terms of the material yield strength  for the API 6B Threaded Flange to the respective ASA B16.5 flanges like the 600 lb, 900 lb and 1500 lb.

The main distinguishing point between the original ASA flanges and the Api Adapter Flanges is the method of changing the ASA term “lb.” to the API term “SERIES”. For instance, the ASA 4″ 900 lb. flange has a working pressure of 2160 psi can be compared to API 4″ SERIES 900 flanges, which has a working pressure 3000 psi. 

Dimensionally, both these flanges are the same with different names, material strength, and working pressure.

The first specification, issued by the API is for wellhead flanges as 6B, which was later incorporated into API 6A. The original flange specifies and retains the designation 6B. All API flanges accepted for wellhead use have a Api Ring Joint Flanges. 

Usually, most API flanges may have Full Face or Raised Face geometry, with either type having a specified ring groove. Most wellhead manufacturers make their 6B flanges full face.

Today, Api 6a Flange Material specifies standard service temperatures of the Api Plate Flanges ranges between   -75° F to 250° F. Currently, the API Spec 6A flanges classed as API 6B Instrument Flange by the API . 

This is because they are easily identified by the fact that they have ring grooves that accept either the R or RX ring gaskets, both of which have identical dimensions with ANSI B16.5 flanges.

Both the Api Series B Flanges , i.e. – 6BX and 6B (welding neck flanges, blind flanges, target flanges and test flanges) are fully conformed to API 6A. The Api Flanges Material consists of modern alloy. 

Hence, the Api 5l Grade B Flanges are produced steel using advanced manufacturing techniques. The Carbon Steel API 6B Spacer Flange known to be robust in performance and have a high cost.
