A105 Heavy Duty Blind Flange, A105 Heavy Duty Blind Flange, A105 Heat Exchanger Flange, ANSI/ASME B16.47 Series B Blind Flange, a105 blind flange, A105 Marine Flange,A105 Heavy Duty Blind Flange,ANSI B16.47 Series A Blind Flange

A105 Heavy Duty Blind Flange is a specialized type of forged carbon steel flange designed to seal the end of pipelines or pressure vessels in high-stress industrial environments. Manufactured using ASTM A105 grade carbon steel, this flange offers superior strength and durability under high-pressure and high-temperature conditions. The "heavy duty" specification implies increased wall thickness and a robust design to handle more demanding applications compared to standard blind flanges.

As a manufacturer, stockist, and exporter, many global suppliers—including firms based in India and other industrial hubs—supply A105 Heavy Duty Blind Flanges for use across oil & gas, petrochemical, refinery, power generation, and offshore industries. These flanges are available in a wide range of sizes and pressure ratings (Class 150 to 2500), and are manufactured in accordance with international standards such as ASME B16.5 and B16.47.

A105 Heavy Duty Blind Flanges are especially valued in markets that demand both strength and reliability. They are forged for structural integrity and are capable of withstanding high mechanical stress. These flanges also provide excellent sealing performance, making them suitable for systems that must be closed off securely during maintenance or isolation procedures.

These flanges are widely exported to several international markets including Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, the USA, Canada, and various countries across Africa. Exporters maintain ready stocks to ensure timely delivery and often customize coatings such as galvanizing, painting, or PTFE for specific environments, especially in corrosive or marine settings.
