Metal hose

Metal hoses are flexible corrugated “pipes”manufactured by forming of thin metal sheets from stainless steel. For increase of pressure resistance and mechanical protection are metal hose braided by wire from stainless steel. To hoses are welded threaded, flanged, and welded fittings, or special fittings defined by drawing or standard.


Lengths of hoses and combination of fittings are always individual, according requirements of customer.

    • Metal hoses are manufactured in dimensions from DN5 up to DN 500

    • Thermal resistance of metal hoses is from -196°C up to 600°C


    Metal hoses are in standard execution from stainless steel resistant in range of temperature -190°C up to 600°C. In case of higher working temperatures in thermal range 100°C up to 600°C is nominal pressure PN mentioned in tables of individual types of hoses reduced by particular coeficient kt, which takes into account working temperature of transported medium or outside temperature and type of hose material. Allowed working pressure pallow=PN x kt.

    Pressure resistance of hose depends on dimension of hose, type of braiding and working temperature of medium.


    Use of metal hose

    Metal Hose is frequently used in piping situations where:

    •There is a need to absorb the heat or pressure-induced expansion of the pipe system.

    •There is a need to compensate for misalignment, or to allow lateral movements of the system during exploitation.

    •High temperature fluids or gases have to be safely conveyed through a system under high pressure or under vacuum conditions.

    •When a system is subjected to a vibration there is a need for special products like corrugated metal hose.

    •When a system is exposed to high external heat, corrosion, or heavy or rough handling.


    Our Metal Hose is used in many traditional and newly developed applications.


    For example, in the petroleum industry Zhongbo metal hose is used for connections on catalytic cracking units, in oil and gas burners and as water lines on gas engine cooling systems. In chemical plants, corrugated metal hose is used for connections to weigh scales, for loading and unloading tank trucks, for steam lines and for conveying any highly corrosive media.


    Steel plants use ZhongBo corrugated metal hose in applications such as cooling water hoses at furnaces and oxygen lance hoses, in high temperature lubrication lines, and for cooling power lines to electrical furnaces used on special alloy steels. For use in the transport of frozen foods, manufacture of semiconductors, application of magnetic resonance imaging and beyond, companies rely on ZhongBo metal hose to transport cryogenic liquids, including liquid nitrogen, helium and hydrogen.


    In the power generation industry, ZhongBo hoses are found in many facilities that employ steam and combustion turbine systems. Heavy-duty hoses can be fabricated from alloys developed specifically for very high temperatures. ZhongBo’s products are also used as a cooling aid to turbine blades on gas fired units, as a fuel atomizer line for oil fired burners and for conveying gas to gas fired burners.


    ZhongBo metal hose can also be found in heating, ventilation and air conditioning systems in both industrial and high-rise buildings. Some examples include pump connections to eliminate vibration on hot and chilled water pumps, for taking up lateral movement caused by expansion and contraction of piping and transitions imposed by seismic forces. They can also used as vibration isolators on refrigeration units and air conditioner compressors and cooling towers.


    ZhongBo is an ISO certified company with unique manufacturing and production processes that create high quality products that are safe, durable, and economic to use.
