Range of options forTube and pipe processing

We have many years of expertise in potential further processing steps for steel tubes and pipes. In collaboration with selected partners we can offer a wide range of processing options. Depending on the tube and pipe dimensions, our services range from sawing and chamfering the tube and pipe ends to complex bending operations.

For precision steel tubes, it is also possible to improve concentricity through turning and grinding, create complex geometries using processes such as round swaging or axial forming, and modify material properties through partial heat treatment.

Drilling / punching / laser cutting

Creation of defined holes or notches within the tube wall.

Peeling / roller burnishing

Process to improve tube surface quality. This can either be done by machining the tube surface by peeling or by roller burnishing (chip-less process).

Cold forming

Shaping of a steel tube by cold-working processes carried out at room temperature.

Cutting / Sawing

Long tubes are not always required. In these cases, tubes can be cut to the different lengths required.

Chamfering

Cutting of the edge at the tube end at an angle other than 90 degrees. Commonly used for welding or other joining operations.

Deburring

Cutting operations can leave sharp, unwanted residual material on the tube end. This material can be removed by deburring.

Thread rolling / threading

Creation of an internal or external thread at the tube end in order to connect tubes with each other or with additional equipment.

Partial hardening

Partial hardening of steel tubes, commonly known as surface hardening or case hardening, is a heat treatment process that increases surface hardness and wear resistance while maintaining the ductile strength of the interior tube wall.

Turning / milling / grinding

Turning, milling, and grinding are primary subtractive manufacturing processes used to remove material from the tube surface. Turning rotates the workpiece against a single-point tool. Milling utlilizes a multi-point cutter to remove material. Grinding uses an abrasive wheel for high-precision finishing.

Swaging / expanding

The diameter at the tube end can be either increased by expanding or decreased by swaging operations.

Bending

Metal forming process which results in a plastic deformation of the tube up to a bend radius of 180°.

Cutting to exact lengths

Mannesmann Line Pipe operates its own sawing centers, where pipes can be cut to short lengths and precise lengths according to customer specifications.

Production of grooved pipe ends

To prepare pipes for connection using Victaulic couplings, Mannesmann offers the service of machining corresponding roller-grooves at both ends of the pipes.

Chamfering

Mannesmann pipes can be manufactured and supplied with various bevels, including custom geometries tailored to customer specifications.
