Hongruntong Marine Unveils Next Generation High-Performance Buoyancy Bags, Setting a New Benchmark for Marine Safety and Efficiency
BEIJING, CHINA – November 18, 2025 – Hongruntong Marine, a leading manufacturer of marine engineering solutions with over three decades of expertise, today announced the launch of its next-generation series of High-Performance Buoyancy Bags. This new line, engineered with breakthrough material science and advanced structural design, is set to provide superior safety, reliability, and cost-effectiveness for maritime salvage, underwater construction, and heavy-lift operations worldwide.
A primary challenge in marine operations is the controlled lifting, positioning, and supporting of heavy loads. Traditional methods, often reliant on rigid and cumbersome equipment, can be prohibitively expensive and lack flexibility.
Hongruntong's new Buoyancy Bags address these limitations head-on with their exceptional flexibility, industry-leading weight-to-buoyancy ratio, and superior performance in diverse and demanding environments.
Technological Innovation and Core Advantages
The next-generation Buoyancy Bags are the result of extensive research and development, offering significant advantages:
Advanced Abrasion and Puncture-Resistant Material: Constructed with a proprietary, multi-ply reinforced composite rubber and high-tensile industrial polyester cord canvas, the bags offer exceptional durability against abrasive surfaces like docks and rocky seabeds, drastically extending their service life.
Optimized Structural Engineering for Balanced Load Distribution: Utilizing Computer-Aided Design (CAD), the bag morphology and seam structures have been optimized to ensure even stress distribution under pressure. This eliminates weak points and provides unparalleled stability during critical lifting operations.
Integrated, High-Pressure Accessory System: The bags are complemented by a full suite of robust accessories, including high-flow inflation valves, calibrated safety relief valves, and professional-grade repair kits. This ensures easy deployment and multiple layers of operational safety.
Broad Application Scenarios
Hongruntong's Buoyancy Bags are versatile tools designed for a wide range of complex marine applications, including:
Ship and Wreck Salvage Operations
Installation and Maintenance of Subsea Pipelines and Equipment
Controlled Launching and Landing of Vessels
Buoyancy Support for Temporary Docks and Work Platforms
Raising and Positioning of Sunken Structures
"For over 30 years, our mission at Hongruntong Marine has been to solve the most pressing challenges faced by our clients in the marine industry," said the Chief Technology Officer of Hongruntong Marine. "This new generation of Buoyancy Bags is more than just a product; it is the embodiment of our commitment to innovation, safety, and operational excellence. It empowers our clients to execute complex marine projects with greater confidence, reduced cost, and enhanced safety margins."
