Hollow rod heat washing process , which improves effi-ciency and reduces cleaning cost , provides an effective technical means for oil well paraffin . At the same time , it guarantees the continuity of oil well operation . In the using process , it can make metal fatigue and corrosion to influence the life of hollow rod . Finite element stress anal-ysis can provide a reference for the hollow rod design and daily main-tenance .
