Product Description


                                                                                                                                                                                                                                                                                                                                                                                                                 The advantages  of   antiseptic   products
    
  1, the most  perfect  impact  resistance,  friction  resistance,  shock   resistance   and  the  covering  materials  is  not  easy  to  be  damaged   when  constructing.
   2,highly  resisting   acid ,alkali  and  salt  and  good  corrosion   resistance .
   3,electric  insulation,highly  electrical-shock  resistance.
   4,low  rate  of  oozing  water   .
   5,long  usage-life.
                               
                          The  usages  of   antiseptic   products  
   1,on-under  ground  tubing   for   gas.
   2,tubing   for  oil  tubes   and  oil -storage  groove.
   3,safe-guard  tubes  for  electric  power  and  communication.
   4,all  chemical   and  industrial  tubing.
   5,tubes  for  water  -transportation.
   6,passing-through  pushing  tubes.
   7,other  usages.
