Manufactured using premium steel grades including 30CrMnSiA, 45MnMoB (A grade), XJY850, BG850 (B grade), RS950, and European/US Standard 40/41. All materials undergo rigorous spot-check verification upon delivery.
Comprehensive heat treatment enhances material strength and extends thread wear life. All treated tubes undergo laboratory testing for strength, hardness, straightness, and concentricity.
CNC lathes and form cutters ensure thread accuracy, minimizing human error. Thread surfaces are cleaned and phosphated to remove burrs and improve surface conditions.
