Metal hose is an important connecting component in engineering technology, which is composed of corrugated flexible pipe, mesh sleeve, and joint.
Used as compensating element, sealing element, connecting element, and shock absorbing element in various gas and liquid pipeline systems and length, temperature, position, and angle compensation systems, used in aerospace, petrochemical, mining electronics, machinery and shipbuilding, medical Health, textile electronics, energy construction and other fields.
The latest national specification for metal hoses is "General Technical Conditions for Corrugated Metal Hose" (GB/T14525-2010), which came into effect on October 1, 2011.
The metal hose is made of austenitic stainless steel material or materials according to user requirements, with excellent flexibility, corrosion resistance, high-temperature resistance (-235 ° C ~ +450 ° C), high-pressure resistance (up to 32MPa), in It can be connected in any direction in the pipeline to compensate for temperature and absorb vibration, reduce noise, change the direction of medium conveying, eliminate mechanical displacement between pipelines or between pipelines and equipment, etc. Double flange metal corrugated hose has displacement and vibration. It is especially suitable for flexible joints of various pumps, valves, etc.
