ISO 6164 Flare Flange Clamps are specialized hydraulic connectors designed for high-pressure systems in industries such as marine, heavy machinery, and offshore engineering. These clamps feature a four-screw, one-piece square flange design standardized under ISO 6164, ensuring leak-free performance and compatibility with 1" to 4" pipelines.

Material Options: Available in carbon steel (ASTM A105) or stainless steel (ASTM A182) for corrosion resistance in harsh conditions.
Flare Interface: The 37° flared tube end ensures smooth, secure sealing with O-ring grooves for soft-seal inserts, eliminating welding-related risks like deformation or porosity .
Split-Clamp Mechanism: Simplifies installation and maintenance without disassembling pipelines, ideal for confined spaces .
Complies with ISO 6164, SAE J518 Code 61/62, and CCS/ABS/DNV marine certifications .
Rated for pressures up to 400 bar (5800 psi), tested for hydraulic fluid compatibility and thermal stability .
Shipbuilding: Approved for marine hydraulic systems (CCS-certified models).
Industrial Machinery: Used in steelworks, mining equipment, and hydraulic test stations.
Energy Sector: Deployed in offshore oil/gas platforms due to corrosion-resistant stainless steel variants
Global Standards Compliance: All products meet ISO 6164 and SAE specifications for interoperability.
Reduced Downtime: Non-welded design cuts installation time by 50% compared to traditional methods.
Technical Support: Free CAD drawings, pressure-drop calculations, and 24/7 engineering assistance.
