API 6A Flange Supplier, Manufacturer

Unichem Steel & Alloy Pvt. Ltd. is renowned API 6A Flanges Manufacturers, Supplier, and Exporter in India. API 6A Flanges are typically a section of applications within the petroleum and fossil fuel industries. These flanges are designed and made to be durable, especially when the API 6a 6b And 6bx Flanges are a part of high-pressure environments or various working conditions. The main function of the API 6a Blind Flange is to affix pipe together while increasing the support strength, they could even be used to block off a part of a pipe, valve, or equipment during a pipeline. Since toughness and hardness are the main characteristics of API 6A Flanges, in many instances they’re surface treated with different coating materials to boost their generation, similarly to their corrosion resistance properties. Although the API 6A WN Flanges tend to have far better corrosion resistance properties, the class of chrome steel utilized is going to be dependent on its application. These API 6A Flanges are designed to affix pipes together, increase support strength, or block off a pipeline. API 6B Flanges are of a through-bolted and studded design. API 6A integral flange works at the temperature of -75 degrees to 250 degrees F. The size of this is similar to ANSI B16.5 flanges. API 6bx Weld Neck Flange contains a minimum wall thickness of 200 inches. These are utilized in the areas where high pressure is required.
