Marine Float Type Air Pipe Head from GREAT MARINE VALVE COMPANY
The Marine Float Type Air Pipe Head is a critical deck-fitting component designed for use in the oil tanks, water tanks, and other enclosed compartments of ships and offshore platforms. Its primary function is to maintain air pressure balance inside the tanks, allowing air to enter or exit as the liquid level changes, while preventing seawater, rain, and contaminants from entering the tank.
This product is manufactured in strict accordance with the latest national and industry standards, including CB/T 3594-94 and CB 20037-2012, ensuring reliable performance in harsh marine environments. It is widely used in shipbuilding, ship repair, and offshore engineering projects worldwide.
Key Features
• Effective Water & Dust Prevention: Equipped with a high‑sealing float mechanism that automatically closes the air passage when waves or rain impact the deck, preventing water ingress.
• Smooth Air Flow: Large air passage cross‑section ensures rapid pressure equalization, reducing the risk of tank deformation or damage.
• Durable Construction: Available in high‑quality materials such as cast iron, cast steel, stainless steel (304/316), and aluminum alloy, suitable for various marine corrosion conditions.
• Easy Installation: Standard flange connection (compliant with GB 569 / GB 2501) allows for simple mounting and replacement.
• Multiple Certifications: Can be supplied with certificates from major classification societies (CCS, BV, LR, DNV, ABS, etc.), meeting international shipping requirements.
