Huashang specializes in providing high-quality pipelines. Our pipeline inner walls are no scale, pits, scars, inclusions, and oil pollution. The wall thickness is uniform and has good characteristics such as high temperature resistance, high pressure resistance, and corrosion resistance. Huashang seamless pipes fully meet the standards in terms of mechanical properties and chemical composition.

  In order to ensure the quality of seamless pipes, our seamless pipe factory -YONGHSNAG with 30 years manufacturing experience,they own automatic heat piercing production line,automatic temperature-controlled natural gas annealing furnace ,precision cold rolled line equipment ,each specification automatic straightener,automatic temperature-controlled cycle pickling passivation equipment ,semi-automatic cold -drawing production equipment and so on. and we also own  a full set inspection/testing equipment including Germany-imported direct-reading spectrometer,ultrasonic fault detector,eddy current flaw detector,hydrostatic test machine,universal testing machine,impact tester,endoscope etc.

  HUASHANG seamless pipes are widely applied to such fields as petrochemical engineering,oil well/oil field,solar energy poly silicon,ocean engineering,shipbuilding ,boiler heat exchanger,aerospace/aviation,environmental protection equipment ,mechanical processing,automobile,medicine,food,hydro power,nuclear power,urea chemical fertillizer,refrigeration and new energy equipment etc.
