Machinesfor pipe mills

For rolling mills and sheet metal processing companies, recorded product quality control is crucial - after all, high-quality end products are to be manufactured. Instead of time-consuming manual checks, we have developed an automated sheet metal measuring system that can be used as a mobile full gantry, either as a stand-alone solution with a sheet support table or integrated into production lines.

We configure your machine entirely according to your requirements!

• Practice-oriented system concept with high-quality measuring technology
• Measurement of sheet length, width and thickness
• Measurement of the cladding thickness of roll- or blast-clad sheets
• Detection of the sheet shape (sabre shape, constriction, bulge)
• Detection of sheet curvature in the transverse direction (flatness)
• High measuring accuracy and reproducibility thanks to linear axes
• Stable machine construction with servo drive technology
• Main control system with complete control panel based on Siemens S7
• Data recording with measurement protocol according to customer requirements
• Minimization of the measurement error rate
• Time and cost savings
• Remote maintenance module for fast support

Perfectly bent sheet metal edges for large pipe production: A sheet metal bending press from AWS Schäfer makes it possible for you.
Our latest generation of machines offers up to 35,000 kN press force and a forming length of up to 1,200 mm to bend high-strength materials on both sides in a short cycle time.

• Sheet centering during forming
• Reduced number of tool sets thanks to an innovative tool concept
• Easy adaptation to a wide variety of tools thanks to a user-friendly tool change concept
• Practice-proven tool design for perfect bending results and long tool life

Skillfully mastering high requirements: With our pipe calibration press, you can meet international specifications (such as API 5 L, ASME/ASTM, GOST) and high shape tolerances. Efficient calibration of longitudinally welded large-diameter pipes - take advantage of our pipe calibration press!

• High-quality and fast straightening process of the pipes for straightness
• Tight roundness tolerances even with thin wall thicknesses
• Simple operation thanks to fully automatic process control system, optionally with automatic measuring system for the pipe ends
• Possibility of pipe manipulation during the calibration process
• Cost-effective and flexible tool concept with time-saving tool change and increased tool service life
• Possibility of plastic circumference reduction of pipes

Solve all tasks with one machine: The CNC pipe end milling machines from AWS Schäfer perform circular processing of pipe ends for inductively bent pipe elbows, straight pipes, T-pieces and other cylindrical components for optimum weld seam preparation.

The double-sided milling machine for LSAW large-diameter pipes can enable synchronized machining of both pipe ends in just one clamping operation. More productivity. Highest machining quality. For pipe bending companies, we also offer a special solution with a double clamping device that efficiently machines a wide range of pipe bends and other cylindrical components.

• Heavy, stable and vibration-damping design
• Precise and reproducible weld seam preparation
• Simultaneous processing of both pipe ends in one clamping operation
• Designed as a single solution or in an automated production line
• Double workpiece clamping device for pipe bends to reduce production costs and increase productivity
• Clean metallic surface of the edges and high geometric accuracy
• Consistently uniform welding root face dimensions thanks to the pipe end circumference copying function

The Spitfire technology from AWS Schäfer revolutionizes submerged arc welding (SAW) technology with innovative wire preheating. Your advantage? This world's first and new process significantly increases the deposition rate without the need for additional wires on the welding head. This saves you both time and materials. Spitfire technology gives you more precise and efficient weld seams, meets the ever-increasing demands of the industry and offers you both economic and ecological benefits.

Induction bending technology from AWS Schäfer offers you precise and efficient bending of pipes, T-beams and profiles, ideal for the petrochemical, oil and gas sectors as well as power plant construction. Our machines enable you to make precise bends with minimal wall thickness reduction and high dimensional stability. Our patented technologies ensure efficient and user-friendly handling, while integrated systems ensure precise geometries and increased product quality. You benefit from reduced costs and increased efficiency.

AWS Schäfer's hydroforming technology is ideal for the production of complex components such as T-fittings and bends in the oil and gas sector. A pipe is precisely formed in a hydraulic press using a liquid medium. The process enables the use of different materials and wall thicknesses in the same tool and offers maximum dimensional and repeat accuracy. Shorter process steps. Low energy consumption. Short cycle times. Hydroforming offers you economy and efficiency throughout the entire production process!

AWS Schäfer's clad pipe technology offers you a cost-effective solution for pipes that have to withstand extreme corrosive conditions in the oil and gas industry. Hydromechanical cladding firmly bonds a corrosion-resistant liner and a carbon steel pipe using high-pressure fluid. This technology enables flexible material combinations, such as ferritic and austenitic steels, as well as aluminum or titanium as liners. The clad pipes produced on our machines offer high corrosion resistance and precise dimensional tolerances, combined with low susceptibility to defects and low investment costs.

The submerged arc welding systems (SAW) from AWS Schäfer offer you maximum efficiency and quality when welding long seams! Our systems can be configured flexibly with up to five welding heads and energy-saving inverter technology. You benefit from a user-friendly control system that integrates all common welding power sources and an innovative welding powder supply system that focuses on sustainability and high powder quality. These tailor-made solutions improve your productivity and reduce your operating costs at the same time.

Whether sheet metal measuring system, sheet metal bending press, pipe calibrating press or pipe end milling machine - our pipe mill technology solutions offer maximum precision and reliability for your demanding pipe production projects! Our modern sheet metal measuring and forming systems as well as end processing machines are in use worldwide and can be seamlessly integrated into existing or newly planned pipe mills.

If standard machines do not meet your requirements, our custom-made machines come into play! Our team of engineers can look back on numerous successful projects in the implementation of individual machines for forming and processing steel and pipe products. We also carry out retrofits, upgrades and conversions of machines and systems.
