HAEUSLER PIPE MILL│The solution for the production of LSAW pipes
LSAW pipework
made by HAEUSLER
From sheet metal to pipe
with quality
The roll bending process is one of the most economical and flexible technologies for manufacturing LSAW pipes. It is designed for industrial applications and enables high bending quality and stable processes across a wide range of pipe dimensions. HAEUSLER roll bending systems combine advanced technologies in a coordinated overall system and overcome the limitations of conventional press forming processes. The result is precise bending, consistent roundness, and high process stability – even with changing material properties. This creates a continuous manufacturing process that ensures efficiency, flexibility, and quality from sheet metal to pipe and forms the basis for reliable welding processes and tight tolerances.
THE RIGHT FORMING TECHNOLOGY FOR LSAW PIPES
In LSAW pipe production, process stability, quality, and cost-effectiveness determine success. Roll bending offers decisive advantages over UO and JCO pipe mills – especially in terms of flexibility, bending quality, investment costs, and return on investment.
| PLATE BENDING – PIPE WORK | UOPIPE MILL | JCO PIPE MILL | |

HAEUSLER solutions in detail│Machines for pipe production
MACHINES AND PROCESSES THROUGHOUT THE ENTIRE PIPE PRODUCTION PROCESS
HAEUSLER offers coordinated solutions for every step of LSAW pipe production. Machines, processes, and automation solutions work together seamlessly throughout the production sequence – from sheet metal bending, edge forming, and welding to final calibration and testing of the pipe. The individual solutions are presented in detail below.
RMS 3-roll round bending machine │ The heart of tube production
Roll bending machine
for the right process
The HAEUSLER RMS 3-roll bending machine stands for precise, flexible, and highly productive pipe bending in LSAW pipe mills. It is the only system in the world that combines three bending processes in one machine. Thanks to its high versatility, the RMS is ideal for demanding industrial applications in pipe production.

Fast, precise, versatile Pipe manufacturing with maximum flexibility
NABM post-forming machine│Gentle on materials and fast
PERFECT EDGE FORMING
FOR ALL PIPE DIMENSIONS
The consistent post-bending – currently the most advanced method for producing straight pipe ends on preformed slotted pipes.
Continuous forming without a transition zone ensures the highest pipe quality and flawless weld seams with simple operation, high output, and no impairment of the base material.

CRWM welding machine│Flexible, fast, and economical
THE BASIS FOR EVERY WELD
100 % FLAWLESS PIPES WITHOUT EDGE MISALIGNMENT
Precise edge alignment and uniform tack welds are crucial for pipe quality. The latest tack welding machine from HAEUSLER features active edge control, CNC laser tracking, and digital welding. This ensures flexible production while maintaining stable, consistently high quality standards.

CMR Fullbody Pipe Expander │High-tech for your pipe factoryk
EXPANDER – TAKES YOUR PIPE
TO THE HIGHEST LEVEL OF QUALITY
Mechanical expansion through gradual widening calibrates the entire pipe evenly. This ensures consistently tight tolerances in terms of diameter, roundness, and straightness. At the same time, the weld seam is checked and the yield strength of the pipe material is increased.
As the final forming step, the expansion defines the final pipe geometry in accordance with the required standards. HAEUSLER supplies complete solutions from a single source – including pre-washing, pipe expansion, expansion tools, post-washing, and water treatment.
