Pipe Beveling Machines

Perfect weld seam preparation through mechanical chamfering of the pipes

The pipe beveling machines are used for beveling pipes and for pipe end machining of nozzles and headers. In addition, the machines are also suitable for fin tubes, boiler tubes, membrane wall and heat exchangers for pipe end machining in both workshop and construction site use.

Particularly in connection with orbital welding, economic manufacturing possibilities arise.

Internal and external clamping pipe milling machines

Mobile pipe beveling machines for perfect weld seam preparation


The transportable pipe beveling machine is used for weld seam preparation when welding thick-walled pipes, boiler tubes and headers. Due to an extremely compact design, pipes can be beveled perfectly even in confined spaces.

DLW-Cut and Beveling machines

Cutting thick-walled pipes on site

The pipe cutting and beveling machine is used to cut and bevel thick-walled pipelines in explosive areas such as e.g. oil and gas platforms, nuclear power plants and other explosion-protected areas.

Boiler Panel Saw Type BWC

Separation of boiler and fin tubes

The cutting of boiler tubes during inspection and main­tenance in boiler construction without a heat-affected zone is a prerequisite for good weld preparation.

CPC / CPC-B

Chain guided pipe cutting and beveling machine

Pipe cutting and beveling, directly on the construction site. The CPC-B type pipe cutting and beveling machi­ne offers a versatile solution for almost all cutting and beveling applications. The machine is convincing in the most difficult conditions and can even be used under water and cut pipe thicknesses up to 50 mm separate.

Mechanical external cage clamp

Tack version – with flat crossbars for pipe sizes from 4″ up to 20″

The mechanical external cage clamps in light design are suitable for the range DN 80 – DN 450 and only for tacking. The pipe ends are clamped via the eccen­tric by means of bars.

Mechanical external cage clamp

No tack version – with arched crossbars for pipe sizes from 24″ – 60″

The widely recessed bridges allow up to 80% of the root pass to be achieved without loosening the centering. The pressure screws allow deformed pipes to be aligned so that flush tacking is possible.

Hydraulic external cage clamp

No tack version – with arched crossbars for pipe sizes from 12″ up to 60″

Due to the widely recessed bridges of the hydraulic external pipe centering, up to 90% of the root pass can be welded without loosening the centering. The edge offset is eliminated by driving the splitting iron under the obliquely chamfered bridges.

All clamps including a built-in hydraulic cylinder. The hydraulic cylinder Is equipped with a locking device and is secured against the housing with a ring on the trapezoidal threaded piston stand after pressing on. The cylinder should be used in the ver¬tical position.
