H₂S in the formation will erode the common pipe in the well, and reduce the life of the well.The cementing tools and accesories are made of the stainless steel with good mechenic
performance to resist the H₂S erode.
Features:1.Material meets the requirements that API recommend.
         2.Special heat treatment technology makes the mechanical performance meet the design requirements.     
         3.All the components that contact with the corrosive medium are made of special alloy steel.
