Metal hoses are essential components in engineering systems, designed to connect different parts of a pipeline while allowing for flexibility and movement. They consist of a corrugated flexible tube, a braided mesh sleeve, and a connecting joint. These hoses serve multiple functions, such as compensating for expansion or contraction, providing a seal, enabling connections, and reducing vibrations. They are widely used in various industries including aerospace, petrochemicals, mining, electronics, shipbuilding, medical equipment, textiles, energy, and construction.
Manufactured from austenitic stainless steel or customized materials based on customer needs, metal hoses offer exceptional softness, corrosion resistance, high-temperature tolerance (-235°C to +450°C), and high-pressure resistance (up to 32MPa). Their flexibility allows them to be connected in any direction within a pipeline, helping to absorb vibrations, reduce noise, redirect the flow of media, and eliminate mechanical displacement between pipes or between pipes and equipment. Double-flange corrugated metal hoses are especially suitable for use with pumps, valves, and other industrial components.
As a key pressure-bearing component in piping systems, the metal hose is typically covered by a bellows structure. Depending on the pressure and application environment, one or more layers of stainless steel wire or strip can be used for reinforcement. The pressure range for Twilight brand hoses generally spans from PN0.6 to 32.0MPa, with some models capable of handling up to 42.0MPa. Since the main components are made from austenitic stainless steel, these hoses provide excellent resistance to both high temperatures and corrosion. They can operate over a wide temperature range, from -196°C to 600°C. Corrosion resistance can be further enhanced by selecting the appropriate stainless steel grade based on the chemical properties of the medium being transported.
Corrugated metal hoses are known for their superior flexibility, fatigue resistance, high-pressure and high-temperature performance, and strong corrosion resistance. Compared to rubber or plastic hoses, they have a significantly longer lifespan, offering better long-term economic value. With the advancement of modern industries, the demand for high-performance corrugated metal hoses that can withstand extreme conditions continues to grow. These hoses are ideal for applications requiring flexible connections to minimize vibration, and they are suitable for transporting steam, gas, air, heavy oil, chemicals, and pharmaceutical products.
