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.
Seamless tube plant process
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.
Technology
PQF® - PREMIUM QUALITY FINISHING
Advanced mandrel mill technology for premium quality finishingWhether 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
