    Detailed Product Description
    Material: Special Top Qualtiy Gelographical Alloy Steel Connection Method: Male And Female Connectction And Joint Connection
    Production Technology: Friction Welding And Built-in Threading Thread Type: Taper Thread And Rectangle Female Thread

     Special Alloy Steel Geological Drilling Pipe with good bending strength with 34 to 60 dia.

     

     Combined with the most advanced scientific research results both in domestic and overseas, our  prouction technology has become perfect. 

     The geographical drill stem is made of top-quality special geographical alloy steel pipe, and the joints is  onf top quality alloy steel and through vaccum quenching and tempering treatment, with higher fatigue  resistance and shearing strength. With advanced friction welding technology and German numerical  controlled production equipent, to get the advantages of high bending strength, firm welds, can meet the  demand of the straightness of deep-hole drilling, with higher fatigue resistance and longer service life. 

     

     OEM is accepted.
