Non-destructive testing and coating solutions THE Rosen Group, headquartered in Stans, Switzerland, will participate at Tube 2016, Germany, this year, where it will present selected solutions to challenges in various industries such as pipe manufacturing, oil and gas and mining.

Many challenges face these and other industries. Tube and pipe manufacturers, for example, must ensure high quality standards during the entire pipe manufacturing process. Pipeline operators, on the other hand, need to stay abreast of any threatening conditions in their lines, such as corrosion, ageing or other types of damage. The Rosen Group draws from its decades of experience and extensive know-how to develop customer-tailored inspection and coating solutions to cope with these issues.

external coatings with outstanding material properties for wear and corrosion protection. Depending on operating conditions, these coatings can extend the life expectancy of slurry, concentrate or tailings pipelines by a factor of five to ten compared to non-coated carbon-steel pipe spools. The result is that shutdowns and maintenance costs are minimised, while the asset’s lifetime is significantly extended.

Rosen’s industrial diagnostics divi- sion delivers customer-operated, quality control-driven diagnostic systems for the pipe manufacturing industry to ensure flawless manufacturing processes. All inspection systems are tailored to the customer’s individual needs and production process. The portfolio comprises consulting, mechanical engineering, automation, development of testing technology, installation and maintenance. With their intelligent plastic solutions division, Rosen delivers internal and

Orbital saw blade for stainless steel tube mills TUBEMASTER Stainless, a product being introduced by Kinkelder, has been developed for cutting stainless steel tubes on orbital flying cut-off machines. a limited maximum line speed. As burr- free cutting of stainless steel usually proves to be a challenge for TCT saw blades, these have not been considered as a reliable alternative. of 0.035/0.05mm per tooth – burr-free cutting up to 3.5m 2 per blade was shown. With these cutting parameters, a line speed of 6.7m/min is still possible. This example shows a clear trade-off between blade costs and production yield.

The new TubeMaster Stainless design derives from the Kinkelder CX 4 concept. On a tube mill with a two-blade orbital flying cut-off unit, producing AISI 304L tubes of 323 x 4mm, it was demonstrated that a cutting speed of 80-100m/min at a feed rate of 0.05/0.1mm per tooth enables a line speed of 10m/min. The blade shows good cutting performance under these conditions by cutting burr-free up to 1m 2 per blade. Under less aggressive conditions – a cutting speed of 60m/min at a feed rate

Extensive testing has demonstrated that TubeMaster Stainless saw blades can cope with cutting speeds from 60 to 100m/min. Blade life of the TubeMaster Stainless averages between 3.5m 2 at 60m/min and 1m 2 at 100m/min, allowing high production output with less downtime. Production of stainless steel tubes is often limited by the speed at which the tube can be cut, typically around 2m/min for large diameter tubes (Ø ≥200mm). HSS saw blades are typically used for this type of application, which results in

The value of the tube being produced combined with the total cost structure (saw blade costs, operating costs per hour, total installation costs per hour) defines which option to choose. Focusing only on lowest blade price or cost per m² cut-surface can lead to missing the optimal economic conditions.
