stainless steel coils tubing Applicationed in :
Industrial stainless steel coil: heat exchanger, boiler, oil,
chemical, chemical fertilizer, chemical fiber, pharmaceutical,
nuclear power, etc.
Liquid stainless steel coil: beverage, beer, milk, water supply
system, medical equipment, etc.
The mechanical structure USES stainless steel coil: printing and
dyeing, printing, textile machinery, medical equipment, kitchen
equipment, automobile and ship accessories, building and
decoration, etc.
Stainless steel bright coil pipe: it is welded by the stainless
steel strip to reduce the wall, the wall thickness is thick to
thin, this process can make the wall thickness even, smooth, and
the wall of the wall of the wall is not welded.It is seamless to
the naked eye, but the process is welded tube.The process of
reducing the wall is accompanied by bright annealing, so that the
inner and outer walls will not form the oxide layer, and the inside
and outside is bright and beautiful, which is needed for medical
products.
