Raw material preparationSelect API standard steel such as J55, N80, or P110Steel grade identification through eddy current testingControl the cutting length error of the pipe blank within ± 0.5mm2. Rough machining stageUse a coupling cutting machine to complete the fixed length cutting of the pipe blankBand saw machining outer circular reference surfaceCNC lathe rough inner and outer diameters, with reserved 0.3-0.5mm precision machining allowance3. Thread processingUsing a 1:16 taper CNC lathe to machine API standard threadsHook type thread design (bearing angle -3 °) to prevent looseningThe thread diameter tolerance is controlled within ± 0.002 inches4. Heat treatment and surface treatmentPerform quenching and tempering heat treatment on steel grades above N80Phosphating treatment forms an anti-corrosion layerCopper plating process (current density 3-5 A/dm 2)5. Quality inspectionThree coordinate measurement of thread geometric parametersWet magnetic particle inspection for detecting surface defects100% full inspection of thread fit for the pass stop gauge6. Finished product processingCoupling painting and rust prevention treatmentLaser marking records steel grade and batch informationSpecial packaging to prevent transportation damagePacskaging ServiceWe offer free product packaging services, including wooden crates, wooden pallets, and customized packaging services..Company ProfileHenan Dongfanglong Machine Manufacture Co., Ltd was established in 1999 and is a national high-tech enterprise concentrating on petroleum specialized pipes, petroleum specialized drilling and production tools, and petroleum specialized automation equipment.
