Check API 6a Flange Material Specification And API 5000 Flange Dimensions.
API 6A Flanges have the standards of the correct specifications to be used in surface drilling and production. These flanges have a long history, and many of these have been discontinued or replaced with a newer version. We are one of the top API 6A Flanges Manufacturers in India who produce high-quality API 6A Weld Neck Flange and other types of flanges with current configurations.
It is to be noted that the ASA and API flanges can have the same dimensions, but they would have different names, material strength, and working pressure. For example, the APA and API 5000 Flange Dimensions would be the same, but they would have a different working pressure. The API 6A Blind Flange is manufactured using alloy steel or carbon steel. These are mainly used for joining pipes or blocking a section of the pipe and increasing the overall support strength. We also manufacture API 6A 6B And 6BX Flanges, which are made of good quality alloy steel using modern techniques. API 6A Type 6BX 10000 PSI Blind & Weld Neck Flanges Manufacturer In Mumbai, India. We produce API flanges with higher pressure ratings like that of the API 10000 Pressure Rating, capable of handling liquids at a higher pressure. Our API 6A BX Flange comes with a maximum working pressure of 5000 PSI. According to the client's requirements, we offer different types of BX flange, including weld neck, blind, etc.
