Repsol Steel LLP is a trusted blind flange supplier, supplying a comprehensive range of blind (BL) flanges to industrial buyers, EPC contractors, and procurement teams across Africa, USA, Mexico, Oman, and Europe. Blind flanges are manufactured as solid plates with no center bore — used to close off pipe ends, valves, pressure vessel openings, and manways, providing a reliable leak-proof seal for isolation, inspection, and future expansion. We supply blind flanges in A105 carbon steel, A182 stainless and alloy steel, A350 low-temperature steel, and duplex grades — with full documentation, EN 10204 3.1 certification, and international packaging standards.
With over 25 years of combined industry experience and a proven export network, we serve clients across Africa, the United States, Mexico, Oman, and Europe — including Oil & Gas, petrochemical, refinery, power generation, chemical processing, and marine facilities. Our supply operations are structured to meet the documentation, packaging, and compliance requirements of international industrial procurement — including Material Test Certificates (MTC), dimensional inspection reports, NACE compliance, PMI testing, ultrasonic testing, and third-party certification where required.
Whether you require standard A105 blind flanges for a refinery in Oman, A182 F316 blind flanges for a petrochemical plant in Mexico, F11/F22/F91 blind flanges for a high-temperature power plant in Europe, or RTJ blind flanges for critical high-pressure gas service in Africa or the USA — Repsol Steel LLP delivers the right blind flange solution, on time, with complete export documentation.
A complete blind flange supply portfolio covering raised face, flat face, RTJ, spectacle, paddle, and custom blind flanges — engineered for isolation, pressure vessel closures, and critical piping systems across Africa, USA, Mexico, Oman, and Europe.
The most common blind flange type — with a raised face where the gasket sits above the bolting surface. Used for pipe ends, valves, and vessel openings in general and high-pressure service.
Grades: A105, A182, A350 LF2
Compliance: ASME B16.5, B16.47, EN 1092-1

A blind flange is a solid plate with no center bore, used to close off pipe ends, valves, pressure vessel openings, and manways. It provides a leak-proof barrier for isolation, inspection, and future expansion — and is commonly used in Oil & Gas, petrochemical, refinery, and power generation piping systems.
We supply blind flanges in ASTM A105 (carbon steel), ASTM A182 F304, F316, F321 (stainless steel), ASTM A182 F11, F22, F91 (alloy steel), ASTM A350 LF2 (low-temp carbon steel), and duplex grades F51, F53, F55.
A blind flange is a single solid plate bolted to a flange face. A spectacle blind (figure-8 blind) consists of two connected plates — one open (ring) and one closed (blind) — allowing quick changeover between open and closed positions for positive isolation without removing the bolts. Spectacle blinds are per ASME B16.48.
Yes. We offer custom sizes, thicknesses, pressure classes, materials, face types, drilled & tapped configurations, and blind flange designs based on drawings, piping specifications, and project requirements — with quick turnaround times.
