Blind Pipe Flanges

Alloy 625 (Inconel 625) EN 1092 Class 150 forged flange offers excellent strength and corrosion resistance in harsh environments like high temperatures, seawater, and acids. Its nickel-chromium-molybdenum-niobium composition provides solid-solution strengthening without heat treatment.

1.4404 steel (AISI 316L) is a low-carbon, molybdenum-alloyed austenitic stainless steel offering superior corrosion resistance, especially against pitting and crevice corrosion in chloride environments. Its low carbon content ensures excellent weldability and resistance to intergranular corrosion, making it ideal for demanding industrial applications.

Steel grade 1.4439 is an austenitic stainless steel with excellent pitting and crevice corrosion resistance in chloride environments. High molybdenum (4.5–5%) and nitrogen content enhance durability and strength, while low carbon minimizes carbide precipitation for maintained corrosion resistance after welding.

1.4435 stainless steel flanges offer superior corrosion resistance with low carbon content (≤0.03%) for excellent weldability. Enhanced nickel (12.5-15.0%) and molybdenum (2.5-3.0%) provide improved pitting resistance, making them ideal for pharmaceutical, biotech, and high-purity applications.

13CrMo4-5 PN16 forged flanges are low-alloy heat-resistant steel components ideal for boiler systems, pressure vessels, and high-temperature piping up to 580°C. Featuring chromium for oxidation resistance and molybdenum for creep strength, they offer excellent durability and weldability for demanding industrial applications.

P245GH EN1092-1 type 05 blind flange features integral forging for high pressure resistance, CNC precision machining for leak-proof sealing, genuine corrosion-resistant materials, and rigorous factory inspection. Custom options available for bulk engineering projects.

Alloy 800HT forged flanges offer superior high-temperature strength, creep resistance, and corrosion/oxidation resistance for demanding oil & gas applications. With controlled carbon (0.06-0.10%), aluminum, and titanium content per ASTM B564 UNS N08811, these nickel-iron-chromium alloy flanges ensure long-term stability in furnaces, petrochemical plants, and power generation.

Alloy 600 ASTM B546 Blind Forged Nickel Alloy Flanges deliver outstanding resistance to high temperature, pressure, and corrosive seawater for offshore petroleum engineering. Certified to ASTM B546 with third-party inspection options, they ensure safety and reliability in demanding marine and oil environments.

X5CrNiMo17-12-2 Plate and blind flanges EN1092-1 316 1.4401 Welding-neck flanges with excellent corrosion resistance, high tensile strength (510-710 N/mm²), and certified impact performance.
