* Custom grades available for sour gas (NACE) or high‑temperature service.
An Ax ring gasket is a solid forged metal seal with an octagonal cross‑section, designed for compact hydraulic connectors in offshore drilling. Unlike standard API ring joint gaskets (oval/octagonal), Ax rings are pressure‑energised and provide a radial sealing effect, allowing lighter weight and faster installation.
The ring must be 15–20 HB softer than the flange faces to deform slightly under pressure and create a leak‑tight metal‑to‑metal seal. If the ring is harder, it may not seat properly, leading to leakage.
Yes, Ax ring gaskets are designed to be direct replacements for API ring joint gaskets in many applications, especially where weight and installation time are critical (e.g., offshore). However, always verify flange groove compatibility and hardness requirements.
Kaxite offers a wide range including Soft Iron, Low Carbon Steel, SS304/316, Inconel® 625/718, Monel® 400, Hastelloy® C276, Titanium, and many more. We also supply NACE‑compliant grades for sour service.
The bevel sealing faces must have a surface roughness Ra ≤ 0.8 µm and be completely free of scratches, cracks, or defects to ensure a gas‑tight seal.
Absolutely. We manufacture Ax ring gaskets in all standard API sizes and can also produce custom dimensions to meet your specific flange requirements.
