DIN3017 Steel Hose Clamp | Worm Drive Clamp for Marine Piping
TheSteel Hose Clamp manufactured to DIN3017-1A standard is the most widely specified mechanical fastening solution for flexible hose-to-pipe or hose-to-fitting connections throughout shipboard piping systems. Our Worm Drive Hose Clamp series features a precision-stamped stainless steel band with uniform serrated engagement teeth, a formed housing that protects the screw mechanism from debris ingress, and an acme-thread drive screw delivering controlled radial compression force without cutting into the hose material—a critical requirement for maintaining long-term sealing integrity under continuous vibration.
In marine service, these clamps secure raw water intake and discharge hoses on main engine cooling circuits, bilge pump suction lines, ballast water treatment unit tubing, fuel transfer lines, hydraulic power pack return hoses, and domestic sewage system connections. The SS316 variant with Precision-Engineered band geometry delivers superior resistance to pitting corrosion in chloride-rich seawater environments, while Dacromet-coated carbon steel options provide cost-effective protection for freshwater and low-corrosion interior installations. As a Specialist Supplier serving global shipyards since 1990, SINOFASTENER maintains ISO Certified Manufacturing processes ensuring every clamp batch passes torque testing and salt spray qualification per classification society requirements.
