The Baker SPD Model F Plunger type valve offers positive and instant shut-off against high or low pressure, assuring continuous control of fluid flow during drilling. The fast-acting plunger valve eliminates breakage of wet joints.*Made of low carbon steel suitable for most applications*Parts are interchangeable with Baker style equipment*Provide added blowout protection at the bottom of the drill*Prevent flow-back when adding joints and bit plugging while making connectionsThis Drill Pipe Float Valve is normally installed in a standard bore-back of the bit sub, to provide fluid flow control at the bottom of the drill stem. It also prevents backflow of cuttings from plugging the drill bit jets while making connections.1..Drill pipe steel specificationSteelGradeYieldStrengthTensileStrengthMin(Mpa)Max(Mpa)Min(Mpa)Max(Mpa)35CrMo948956102010532..Tool JointSpecificationOD2"-6 5/8"ThreadRSC:NC26,NC31,NC38,NC40,NC46,NC50,etc.(NC,XH,IF,REG,FH,etc.)SteelGrade40Cr, 35CrMo, 4137HLength400mm, 1050mm, or as your request.Connectiondrill pipe, drill collar, drill bit.Customizedspecificationscanbemanufacturedaccordingtodrawings.Features and advantages:1. excellent comprehensive mechanical properties.2. wear resistant.3. high fatigue strength and long fatigue life.4. good flushing effect to ensure high drilling rate.5. widely application and accurate size.6. origin of material: our materials are come from bao steel which is the best steel factory in China.
