Product Overview
BELNADE engineers and supplies heavy-duty nickel alloy flanges and custom-forged components designed for critical leak-free joints in extreme environments. Combining superior forging technology with precision machining, our products meet international dimensional standards while delivering exceptional structural toughness under massive pressure and thermal shock.
Standard Dimensions & Size Matrix
Manufacturing Process
Our flanges and custom forgings are crafted from high-purity ingots utilizing heavy open-die and closed-die forging presses. The intense mechanical hammering and grain flow refinement eliminate internal defects and maximize structural integrity. Advanced CNC vertical and horizontal machining centers then perform precision boring, facing, threading, and serration finish machining to match strict international design standards.
Available Alloy Grades
Industrial Applications
High-pressure wellhead equipment, subsea Christmas trees, and valve assemblies
Petrochemical reactor nozzles and high-pressure pipeline connection flanges
Aerospace engine rings, turbine structural mountings, and rotor components
Marine propulsion systems and high-salinity piping connections
Quality Control and Testing
Flanges and forgings undergo rigorous quality inspections, including dimensional verification against ASME/DIN drawings, positive material identification (PMI), ultrasonic testing (UT) for internal soundness, surface defect examinations (MPI/DPI), and mechanical hardness testing. Certified material test reports (EN 10204 3.1) accompany every single forged item.
Packaging and Export
Machined flange faces and gasket contact surfaces are coated with anti-rust protection and covered with heavy-duty plastic protective discs. Products are packed securely inside robust, export-grade plywood crates with internal cushioning to prevent shifting and impact damage during international transport.
