Seamless welded steel tube is the newest high level wear resistant pipe in the world and it is developed by Zhangjiagang Runkun Wear Resistant Material Co., Limited. The base layer is Q235 metal and it is lined with wear resistant alloy materials. One method of producing the pipes is by inner wall welding machine; the machine can also apply to produce wear resistant pipes with small diameter. The other method of producing the pipe is by curling the wear resistant plate. Our factory can produce any pipe with diameter greater than 80mm.
