Hebei Speed Torque Transmission Technology Co., Ltd. proudly presents our premium Rubber Hose for Sand and Grit Blasting, specifically engineered for demanding shipbuilding and steel structure surface preparation environments. With over 7 years of manufacturing excellence and a 3,000-5,000 m² factory, we deliver hoses that combine exceptional durability, flexibility, and safety. Our hoses are designed to withstand the harsh abrasion of sand and grit, ensuring consistent performance and extended service life. Trusted by clients across North America, Europe, and Asia, our product is your reliable partner for efficient blasting operations.
Key Features & Technical Specifications
Superior Abrasion Resistance: The inner tube is made of high-quality natural rubber and SBR blend, providing excellent resistance to wear from sand, steel grit, and other abrasives. This extends hose life significantly compared to standard rubber hoses.
High Working Pressure: Rated up to 12 bar (174 psi), ideal for high-pressure blasting systems used in shipyards and steel fabrication plants. Each hose is hydrostatically tested to ensure safety.
Excellent Flexibility: The hose remains flexible even in cold temperatures (down to -20°C), making it easy to maneuver around complex structures without kinking.
Static Dissipation: Built-in conductive wire or carbon layer safely dissipates static electricity, reducing the risk of sparking in explosive environments (dust and grit).
Weather & Ozone Resistant Cover: The outer cover is designed to withstand UV rays, ozone, and harsh weather, suitable for outdoor use in shipyards.
Customizable Lengths & Couplings: Available in standard lengths of 20m and 30m, or custom lengths. We can pre-attach camlock, flanged, or threaded couplings upon request.
Lightweight Design: Despite its toughness, the hose is lightweight to reduce operator fatigue during long blasting sessions.

Frequently Asked Questions (FAQ)
What is the maximum working pressure of this hose?
Our standard hose is rated for 12 bar (174 psi) at 20°C. Higher pressure options are available upon request.Can this hose be used for wet blasting?
Yes, it is suitable for both dry and wet abrasive blasting, but we recommend a dedicated wet blasting hose for optimal performance in wet conditions.What types of couplings are compatible?
Standard camlock, flanged, and threaded couplings can be factory-installed or supplied separately. Please specify your requirements.Is the hose resistant to oil and chemicals?
The cover is oil-resistant, and the inner tube can handle mild chemicals. For aggressive solvents, please consult our technical team.How long is the hose life under typical shipyard use?
With proper handling, our hose typically lasts 12-18 months in continuous heavy-duty blasting, depending on abrasive type and pressure.Do you provide custom lengths or colors?
Yes, we offer custom lengths, colors, and branding options. Minimum order quantity may apply.What is the minimum bend radius?
Approximately 10 times the inner diameter, ensuring flexibility without kinking.How do you ensure quality?
Every hose undergoes hydrostatic testing and visual inspection per ISO9001 standards. We also conduct abrasion and burst tests periodically.
