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.
Since its invention by the Mannesmann brothers in 1885, SMS group has continuously developed and enhanced the seamless tube production process. This keeps us one step ahead of the demands of the tube and pipe market both now and going forward. Take our PQF® (Premium Quality Finishing) process, for example: with the fourth generation of PQF® plants, our experts have succeeded in achieving a significant increase in output.
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.
