Engineered for reliability in demanding environments, our Cast Iron Compression Flange combines high-pressure tolerance (up to 600 PSI) with exceptional corrosion resistance. Made from premium A356 cast iron and finished via CNC machining, these flanges ensure leak-proof connections in hydraulic, pneumatic, and fluid transfer systems. Ideal for heavy machinery and agricultural equipment, they’re available in standard sizes (1"–24") or fully customized dimensions. With ISO 9001-certified manufacturing and rigorous NDT testing, every flange guarantees long-term performance, even under cyclic loading or extreme temperatures.

Industrial Applications
Customization Options
1. Non-Standard Sizes: Up to 30" diameters or bespoke bolt-hole patterns.
2. Specialty Coatings: Choose Xylan for high heat or Dacromet for saltwater environments.
3. Rapid Prototyping: Get CAD-reviewed samples in 3 weeks.
We handle low-volume orders (50+ units) with the same precision as bulk batches.

Certifications & Testing
Every cast iron compression flange undergoes:

We ship globally via DHL/FedEx for samples or containerized sea freight for bulk orders. Regional warehouses in the EU and North America ensure 7–10 day delivery for standard flanges.
“Switching to rongbaocasting’s flanges cut our downtime by 40%. Their custom zinc-coated units outperformed steel in our coastal plant.”
