Metal hoses are essential connecting components, comprising a flexible tube, a braided mesh sleeve, and fittings. They are characterized by excellent elasticity and low stiffness. The mesh sleeve is woven from stainless steel wire (or strip) and serves both to withstand pressure and to protect the corrugated tube. Metal hoses from Chongqing offer a wide variety of fitting types and configurations, allowing selection based on specific project requirements. With numerous options available, customers can choose according to their particular needs. These hoses find applications in aerospace, aviation, petroleum, chemical processing, mining, electronics, machinery, shipbuilding, medical, sanitary, light‑textile, and construction industries, serving as outstanding elements for compensating length, temperature, or angular changes.

　　Specifications for corrugated hoses and metal hoses; Applications of metal hoses, corrugated hoses, and finned corrugated tubes in internal‑combustion engine coolers. Within the housing of a gasoline or diesel engine cooler, or between the two tube sheets of the cooling core, 1 to 1,000 metal corrugated tubes with intermittent convex–concave profiles are installed. These tubes are secured to one tube sheet using methods such as expansion‑fitting or welding, thereby altering the flow regime of the cooling medium to enhance the heat transfer coefficient and improve thermal efficiency. This invention features a novel concept, practical manufacturing processes, low cost, reliable performance, high heat transfer efficiency, resistance to fouling, long service life, and reduced thermal stress. However, the following points should be observed during operation:
