Pipe Tapering Machine and Furnace

Working principle

The pipe end is heated by an electromagnetic induction furnace, then fed into the tapering machine. A forming mould shapes the heated end until the required profile is reached.

Tube range inputs

Submit raw tube OD, wall thickness, grade, length, straightness and end condition, together with the finished taper drawing and tolerance. If several products share the line, identify the smallest, largest and most difficult tube so the press, tooling and heating duty can be reviewed as a range.

Match the furnace to the model

The supplied data recommends matching furnace capacity to the tapering model and pipe size. Confirm tube grade, diameter, wall thickness and finished taper profile during line planning.

Heating and tapering sequence

The proposed sequence should define tube loading, heating position, target process window, transfer time to the tapering machine, forming strokes, dimensional checking and discharge. The handling method between heating and forming matters because the tube end must reach the tooling in a controlled condition.

Furnace matching

Furnace selection is reviewed with tube section, grade, heated length, cycle expectation, available electrical supply and the forming sequence. A generic power figure is not enough to confirm process performance. Coil design, cooling, temperature monitoring and transfer arrangement should be included in the technical discussion.

Production sequence

Induction heating prepares the tube end for controlled hydraulic forming, after which the taper is produced to suit the next ground-screw fabrication stage. Keeping heating and tapering in one planned cell helps control handling and material condition between operations.

Production-flow interfaces

Show how raw tubes arrive, how heated parts are transferred and where tapered tubes go next. Cutting, drilling, spiral welding, point finishing, coating and inspection may sit around this cell, so loading height, buffer space, lifting method and line direction should be recorded before layout approval.

Choose the model by tube duty

ST-01, ST-02 and ST-03 references cover different pipe diameters, wall thicknesses and taper lengths. Provide the raw pipe specification, finished-point geometry, target cycle time and electrical supply so the tapering press and furnace capacity can be paired correctly.
