Products Description
The main materials of this series of threaded metal hoses are optional 304 and 316L stainless steel. The inner corrugated bellows provide telescopic and bending capacity, and the outer stainless steel braided mesh improves pressure resistance. Both ends are equipped with threaded joints of various specifications such as metric, imperial and NPT. The product has firm welding and reliable sealing, and is resistant to fatigue and not easy to crack after repeated bending. It resists oil, moisture, weak acid and weak alkali corrosion with a wide applicable temperature range. Customization of hose length, thread specification and wall thickness structure is supported, and structural schemes can be adjusted according to pressure and medium working conditions. Produced under ISO9001 quality control system, all products pass pressure tightness test before delivery, suitable for flexible connection between fixed pipelines and vibrating equipment.
Product Advantages
Quick installation with threaded joints for convenient construction
Integrated threaded interfaces on both ends can be directly screwed for connection without welding or flange accessories, realizing high assembly efficiency in narrow spaces and emergency equipment maintenance.
Flexible vibration absorption to compensate displacement deviation
The bellows structure can bend at multiple angles, effectively absorb equipment vibration, compensate pipeline thermal expansion and installation misalignment, reduce pipeline stress and protect precision equipment such as pumps and valves.
Temperature and corrosion resistance for wide working conditions
Stainless steel material prevents rust and corrosion, withstands alternating high and low temperature environments, suitable for conveying steam, hydraulic oil, cooling water and various industrial gases, and resists leakage and rust during long-term operation.
Double-layer protective structure with stable pressure resistance
The inner bellows seals the medium, and the outer braided mesh bears tension and pressure. It is impact-resistant and pulse-pressure resistant, with better anti-fatigue performance than ordinary hoses.
Flexible specifications supporting non-standard customization
Length, nominal diameter and thread standards can be customized as required. Multiple joint types including external thread, internal thread and union nut are available to meet matching requirements of different equipment ports.
Product Application
Featuring compact structure, easy installation and stable sealing, threaded metal hoses are suitable for small and medium-sized fluid transmission under normal pressure and narrow space working conditions. Core application scenarios are as follows:
- Industrial Equipment: General mechanical equipment, electromechanical supporting, hydraulic and pneumatic systems, small unit pipeline connection
- Municipal & HVAC: Water supply and drainage, HVAC pipelines, fire supporting facilities, municipal conventional fluid transmission
- Environmental & Light Industry: Dust removal and environmental protection equipment, light chemical industry, small storage tank medium transmission
It is applicable to various media such as clean water, compressed air, ordinary oil and gas, low-temperature steam and weak corrosive fluids, serving as a versatile and preferred flexible pipe fitting for general industrial pipelines.
Product Q&A
Q: How to choose between threaded metal hoses and flange metal hoses?
A: Threaded metal hoses are preferred for small-caliber, normal-pressure, narrow installation space and small equipment supporting scenarios with simple installation and lower cost. Flange metal hoses are suitable for large-caliber, high-pressure, large-flow and heavy-duty main pipeline scenarios with higher pressure resistance, larger sealing area and more stable connection.
Q: Are threaded joints prone to water and air leakage?
A: No leakage occurs under standardized installation. The hose features accurate thread shape and tight occlusion with stable sealing performance when installed with gaskets or raw material tape. It maintains zero leakage for long-term service without forced or misaligned screwing, fully meeting the needs of conventional industrial pressure working conditions.
Q: Can threaded metal hoses resist high-temperature steam?
A: Yes. 304/316 stainless steel delivers excellent temperature resistance, adapting to conventional low and medium-temperature steam transmission and pipeline compensation. For ultra-high temperature and ultra-high pressure harsh steam environments, thickened pipe bodies and reinforced thread types are recommended for higher safety and stability.
