The steel making process is EBT+LF/VD and ingots are forged to the required form once by hydraulic press machine or rotary radial forging machine. The ultrasonic test is carried on according to JB/T******6. The pipe mould will be quenched, tempered performed relieving stress after rough machining (boring), and then the finished machining will be carried out by numerically controlled lathe to meet the quality requirement. With the same lifetime to those made in America and Germany, our pipe moulds are provided for lots of large manufacturers in China, and are exported to the Central Asia, Europe and North America, etc.
