I. Product Introduction

The Marine Hose Tensile-Bending Fatigue Testing Machine is a specialized testing device designed to simulate the fatigue stresses experienced by marine floating hoses during actual use. It is compatible with marine hoses with inner diameters ranging from 25-300mm, including steel wire wound hoses, braided hoses, and rubber composite hoses, and adopts a frame-type structure.

By simulating the tensile loads and bending deformations that hoses endure in marine environments, it tests their fatigue life, structural integrity, and sealing performance. It can perform tests such as tensile-bending composite fatigue, bending fatigue under constant tension, and tensile fatigue under constant bending.
