We offer open-bottom and enclosed-bottom parachute type underwater air lift bags with capacities ranging from 50kg to 110 tons.

Water Weight Bags

Water-filled proof load bags offer an easy, safe, and cost-effective way to load test lifting equipment and load-bearing structures.

Pipeline Buoyancy Units

Mono buoyancy units enable efficient pipeline operations with time-saving single-point connections and wide-angle adaptability.

Lifeboat Water Weight Bags

We offer specially designed sausage-type, water-filled proof load bags for static and dynamic testing of the lifeboat and davits.
