Why Choose ASTM A516 GR70 Flanges?
ASTM A516 GR70 is a high-strength, fine-grained carbon steel widely used in pressure vessels, boilers, and critical piping systems. Its benefits include:
- High tensile strength and durability under pressure
- Excellent notch toughness, even at lower temperatures
- Reliable weldability, enabling ease of fabrication
- Compliance with international pressure vessel standards
These properties make ASTM A516 GR70 flanges an ideal choice for industries such as:
- Oil & Gas – processing and transport pipelines
- Petrochemical – corrosive and high-temperature service lines
- Power Generation – boiler and turbine connections
- Marine & Offshore – seawater-resistant connections for harsh conditions
Plate Flange vs. Blind Flange – Different Roles in One System
- Plate Flanges (TYPE01 B1): Used to connect pipes, valves, or fittings, offering easy assembly and disassembly.
- Blind Flanges (TYPE05 B1): Designed to seal off the end of a pipeline or vessel, often used for testing, maintenance, or future expansion.
Together, these flanges provide both connectivity and system safety, ensuring efficient and reliable pipeline operation.
Commitment to Quality
All flanges were manufactured with strict dimensional control and supplied with EN 10204-3.1 inspection certificates, verifying both material composition and mechanical properties. Our team ensures that each shipment is tested, documented, and delivered safely, ready for immediate integration into client projects.
