Seamless tube plantsTube and pipe making
Wherever you look, seamless steel tubes are an integral part of modern life. Today, the oil and gas industry, the construction and mechanical engineering industries, and automotive manufacturers demand ever better tubes made of higher steel grades, with closer tolerances and new dimensions.
Ever since the Mannesmann brothers' radical invention in 1885, SMS group has continuously improved the seamless tube production process. That has put us one step ahead of current and future requirements of the pipe and tube market. Take for example our PQF® (Premium Quality Finishing) process and its innovative technology packages. This innovative power proves we offer you competitive solutions for seamless tubes.
Piercing, elongating, and finish-rolling - these are the key stages in seamless tube production. SMS group has the right machines for every stage, and covers the whole range of processes.
Whether it's high-alloy steels or particularly thin-walled precision tubes - with our PQF® (Premium Quality Finishing) technology, you can produce even the highest-grade products efficiently and reliably. You also use less material to generate better output than with conventional solutions. That ensures tool cost plus energy savings due to the low reheating required during the rolling process.

Your benefits from the PQF® process at a glance
- You can roll higher-alloyed steel grades
- Temperature distribution in the shell is more uniform after the
elongation rolling process
- Reduced "finning" at the shell end for lower crop end losses
- Closer wall thickness tolerances
- Higher tube quality
- Lower manufacturing costs
There is a huge demand for the automation of complete seamless tube lines and integrated individual machines, another SMS group specialty.
So, whatever you want, from individual sensors, through drive and control technology, right up to planning and implementation of computer-aided information and control systems: SMS group supplies complete solutions.
You name it - from project planning to system implementation, we devise customized solutions and apply cutting-edge technology to meet your specific requirements.
Included here are:
- Condition monitoring
- CARTA® manufacturing executing systems (MES)
- Radio frequency identification (RFID) tool identification and tracking system
- Pipe and material tracking
- Wireless network (WLAN) design for complete industrial plants
- Mobile panels for remote machine control
- Quality assurance system (QAS)
Using plant simulations, we thoroughly test the capabilities and functionalities of complex industrial plants as early as the project planning and engineering stages. Then we apply the findings to perfect the structure and control strategies of our plants.
Remote access to the machine control system for fault analysis is possible only after authentication by the customer. Direct analysis and evaluation of the operating parameters are performed online by the SMS Service employees. They can easily identify defects and malfunctions and initiate measures for fault elimination. Remote access also allows the system software to be updated. Naturally, the installation of the necessary hardware and software for the remote access is already included in the remote service.
