SMTCL pipe thread lathe is designed primarily for the cutting of cylindrical and tapered metric or inch threads on pipe. In addition, it can also be used for turning externally or internally, for boring holes, turning male or female tapers, and face turning, among other operations.
This pipe thread lathe is applicable in the petrochemical, chemical, hydroelectric power generation, and geological industries, and also for repairing drill string, drill collar, square Kelly, well casing, and so forth. Moreover, our lathe is especially suitable for the repair of pipe in the petroleum related industries.
