Flanges
High-Performance Flange Solutions
ASTM standard flanges are the most critical components used to ensure leak-proof and secure connections in pipelines.
With different connection types and pressure classes, they have a wide range of applications in energy, petrochemical, and heavy industry projects.
FLANGE TYPES
Welding Neck Flanges
The most reliable flange type for high-pressure and high-temperature lines. Its long neck structure distributes stress evenly.
Slip-On Flanges
These flanges, which facilitate assembly, are preferred in low and medium-pressure systems.
Blind Flanges
These flanges, used to close the ends of pipelines, have a non-perforated structure.
Threaded Flanges
A practical connection solution used in systems where welding is not suitable.
Socket Weld Flanges
A compact and durable flange type used in small-diameter and high-pressure lines.
Lap Joint Flanges
Flexible connection elements used with stub ends in systems requiring frequent disassembly and cleaning.
ASTM FLANGE PRESSURE CLASSIFICATIONS
These are standard flange classifications selected to suit different pressure levels.
• Class 150 → Low-pressure systems
• Class 300 → Medium-pressure applications
• Class 600 → High-pressure lines
• Class 900 → More demanding operating conditions
• Class 1500 → Heavy industry and critical lines
• Class 2500 → Very high-pressure systems
