Eccentric different diameter pipe diameter that is multiplied by the head diameter multiplied by the thickness.
Eccentric different diameter pipe standard: GB American Standard British standard and non-standard stamping pressure.
Eccentric different diameter pipe shrinkage diameter of forming process is will and different diameter pipe big endian is equal to the diameter of the tube into the forming die, through the tube along the axial direction of the blank pressing, the metal mould cavity movement along the contraction and forming. According to different diameter pipe diameter size, divided into a press forming or repeatedly pressing forming.
Eccentric different diameter pipe is characterized by intensity was significantly higher than that of the same amount of carbon carbon steel, with good toughness and ductility and good weldability and corrosion resistance etc.. The eccentric different diameter pipe has any special role
