1. The challenges in Fluid Transfer for the Oil & Gas Maritime Industries
In extreme environments such as offshore drilling rigs and supply vessels, the transfer of heavy-duty fluids, including liquid mud, fuel, seawater, and barite, presents significant operational challenges. These demanding applications require equipment engineered for maximum durability and resilience under constant stress
To meet these rigorous standards, the Alfagomma 648AA hose series has emerged as the industry's go-to solution. It is specifically designed for high-performance fluid handling, backed by impressive technical specifications:
Engineered specifically for the Oil & Gas and Maritime sectors, the Rig Supply Soft Wall hose series is defined by its exceptional versatility in transporting various fluids across the most hostile environments. The hose features an optimized three-layer construction for peak performance:
Tube (Inner Layer): Conductive NBR (Nitrile) rubber, reinforced with high-tensile textile fibres and integrated static wires to ensure safe electrical discharge.
Reinforcement: High-tensile textile plies combined with embedded static wires for superior structural integrity and grounding safety.
Cover (Outer Layer): Premium CR (Neoprene) rubber, specifically formulated for high resistance to abrasion, ozone, and hydrocarbons. Most importantly, the cover is fire-resistant, providing an essential safety barrier in high-risk offshore operations.
+ Exceptional Tensile Load Resistance: The 648AA series boasts a massive tensile end load capacity—up to 7,000 kg for the 4” size and 10 tons for the 5” size without structural failure. This is a "game-changer" for offshore rigs where mechanical stress is constant.
+ Superior Pressure Ratings: While the standard working pressure is 300 psi (20 bar), the hose features a burst pressure of 1,200 psi (80 bar)—providing a 4:1 safety factor.
+ Wide Temperature Range: Operates reliably from -30°C to +90°C, making it suitable for even the harshest maritime weather conditions.
2. Precision Hose Assembly Services at Vina-Hydraulic Equipment Joint Stock Company (VHE)
VHE recently completed a strategic order of 4'' (102mm) 648AA Rig Supply Soft Wall hoses, customized to 3-meter lengths for a key partner.
Why do industry leaders choose VHE?
Professional Crimping Techniques: For large-diameter hoses (4”), selecting the correct fittings and applying precise crimping force is vital. We ensure the assembly remains secure and leak-free even under a 300 psi (20 bar) workload.
State-of-the-Art Equipment: Our high-capacity crimping systems guarantee aesthetically clean joints that meet international technical standards.
Expert Craftsmanship: Our technicians possess deep expertise in Rig Supply hose characteristics, ensuring zero leakage and preventing "hose blow-outs" during operation.
3. Pressure Testing – A Commitment to Absolute Safety
At VHE, we recognize that a single leak at sea can lead to catastrophic consequences. Therefore, every assembly undergoes a rigorous Pressure Test before dispatch:
We utilize a 2,000 bar high-pressure testing system (with 1/4" NPT connections) to verify the integrity of every hose. This provides our clients with total peace of mind regarding product quality and operational safety.
Note: With the 648AA’s 1,200 psi burst pressure, users benefit from an extraordinary safety margin.
Peace of Mind in Every Detail
In the Oil & Gas and Maritime industries, the smallest flaw can result in immense financial and downtime losses. Choosing the high-quality 648AA hose combined with VHE’s precision assembly service is the ultimate insurance for your system.
We do not just sell hoses; we deliver safety and enduring operational performance.
