DIPTI METAL INDUSTRIES
Dipti Metal Industries is a Leading global API 6A Flange Manufacturer, API 6A Type 6B 3000 PSI Flange Supplier & API 6A Type 6B 3000 PSI Flange Exporter of 20.7 MPa (3000 PSI) flanged products for critical service in Mumbai, India. API 6A is the principal specification for wellhead and Christmas tree equipment, ensuring reliability in high-pressure drilling and production applications. The Type 6B flange, rated for up to 3000 PSI (20.7 MPa), is a non-mandrel end or outlet connection utilizing a Ring Type Joint (RTJ) for a pressure-energized metal-to-metal seal. We supply API 6A flanged components in all material classes (DD, EE, FF) and Product Specification Levels (PSL 1-4), complete with full traceability and adherence to NACE MR0175/ISO 15156 requirements for sour service. Find certified API 6A Flanges and Fittings here.
Founded in 2009 in Mumbai, India, we are a specialized global API 6A Flange Manufacturer and API 6A Type 6B 3000 PSI Flange Exporter focused on high-integrity components for the energy sector. We understand the stringent requirements of API 6A PSL levels and ensure all our Type 6B 3000 PSI flanges, fittings, and adapters meet or exceed the required pressure, temperature, and material certification standards. Our inventory and manufacturing capabilities are set up for fast, traceable deliveries to oilfield and upstream projects globally.
The API 6A Type 6B flange specifies non-mandrel flanged connections used primarily for wellhead and flow control equipment. The 6B is a non-preloaded flange typically utilizing RTJ gaskets from the R series (e.g., R24 to R74) to achieve a reliable, high-pressure seal at a working pressure of 3000 PSI (20.7 MPa).
