Large diameter seamless pipe mills

Since 1990s when we developed and manufactured Ф2000mm piercing mill for the production of large diameter pipes, we have designed and manufactured Ф508mm, Ф630mm, Ф720mm, Ф1000mm, Ф1200mm large diameter seamless pipe production lines. The large diameter seamless pipe hot rolling mills supplied by us accounts for arround 95% of the market share in China.

  • Hot rolled pipe OD: Ф273mm～Ф720mm
  • Production capacity of hot rolled pipes: Max. 150,000tons per year
  • Cold rolled pipe OD: Ф80mm～Ф711mm

  • Application

    Large diameter seamless pipe mills are mainly designed for producing nuclear power pipe, high pressure boiler pipe,high pressure fertilizer pipe,energy pipe, gas cylinder pipe,structural pipe etc. The piercing techonlogy includes the pressure-piercing techology and croll-rolling piercing technology. The elongation rolling technology includes pilger rolling technology and rotary rolling technology. ...
