Industrial Flange Manufacturing and Custom Precision Machining
As HassasValf, we manufacture flanges at international standards for the critical connection points of heavy industry, petrochemical plants, power generation facilities, and high-pressure pipelines. For these connection elements, which directly dictate system safety and sealing integrity, we provide high-tolerance machining solutions customized to the pressure (PN/Class) and temperature ratings of your process fluid.
Standard and Custom Flange Production Capabilities
In our facility, alongside standard products, we provide the complete scratch manufacturing of complex, process-specific connection elements through reverse engineering. We operate on a strict zero-defect principle for Flat Face (FF), Raised Face (RF), and Ring Type Joint (RTJ) surface finishes.
- International Standard Production: Weld Neck, Slip-On, Blind, and Threaded flange manufacturing in full compliance with ASME B16.5, EN 1092-1, and DIN standards.
- Wide Material Selection: Production utilizing ASTM A105 Carbon Steel, 304/304L and 316/316L Stainless Steel, and high-alloy special steels based on specific process requirements.
- Reverse Engineering and Custom Manufacturing: Precise CNC machining of non-standard, machine- or system-specific flanges modeled exactly from technical drawings or deformed physical samples.
- High-Pressure Classes: Thick-walled, pressure-resistant forged steel flange machining capabilities for heavy-duty lines ranging from Class 150 up to Class 2500 (PN10 - PN400).

Frequently Asked Questions
Do you manufacture non-standard, custom-sized flanges?
Yes, we precisely manufacture custom flanges that fall outside standard ASME or EN norms, tailored to your specific machinery or process. We achieve this by applying reverse engineering from a worn physical sample or technical drawing on our advanced CNC machines.
What material types and surface forms can you produce flanges in?
Depending on the structure of the process fluid, we primarily machine Carbon Steel (A105) and Stainless Steel (304, 316). For sealing surfaces, we offer Flat Face (FF), Raised Face (RF), and Ring Type Joint (RTJ) manufacturing suited to the pipeline's pressure class.
Do you provide rapid manufacturing support during emergency facility shut-downs?
Absolutely. We understand how critical time is during planned or unplanned shut-downs of industrial facilities. Thanks to the flexibility of our in-house machining park, we prevent your production losses by manufacturing your emergency flange and fittings requests in the shortest possible time.
