2009-11-05 By browsing:2136 [Close]

   The company introduced advanced technology and equipment, taking special polyethylene(PE80/PE100) as material, to produce polyethylene pipes. The product include two series of SDR11 and SDR17.6. The class of pressure resistance of SDR11 series of PE80 is 0.4MPa and SDR17.6 is 0.2MPa. The class of pressure resistance of SDR11 series of PE100 is 1.0MPa and SDR17.6 is 0.6MPa.

    OBO Pipe Factory has passed the double system certificates of quality environment of ISO9001 and ISO14001. The gas pipes fulfill GB15558.1-1995 and GB15558.2-1995 standard. It can meet all kind of requirements of transportation gas.

The colors of OBO water supply pipes have yellow and black with yellow color tapes.
