Metal flexible hose
Thread Content
According to available information, the maximum diameter of metal hoses abroad is 6”, with a working pressure of 40 MPa; however, it is not known at present which company in China is capable of manufacturing such hoses.
It seems that the inner part of the flexible metal hose is made of plastic material; could someone with expertise give me some advice?
The maximum pressure for the hoses we use is 25 kilograms
It seems that it’s possible to do this in Zhenjiang, Jiangsu; they often use such coiled heat exchangers in low-temperature methanol washing processes.
The original poster can go and find out whether Nanjing Aerospace Chenguang is capable of doing it
The flexible metal hose seems to have PTFE inside; the maximum pressure I use is 25 MPa, and it’s from Jiangsu
It is said that for such devices, whether they operate under high pressure or low pressure, they were initially manufactured abroad, and only gradually became domestically produced. Therefore, it takes time to absorb and master such technology.
There are likely many manufacturers of metal hoses, found across the country. Most of these hoses use plastic as their inner lining material, but many manufacturers of hydraulic fittings are capable of producing hoses with a stainless steel inner lining, which offers higher pressure resistance and is less prone to damage.
Most metal hoses are essentially metal bellows, with their inner walls also made of stainless steel. Our company specializes in the production of seismic-resistant stainless steel metal hoses for storage tanks, as well as wave compensators
