Stainless steel pipes with an internally polished surface are very important for systems at the pharmaceutical and biotechnological industry. The safe transport of the media and keeping the products clean is absolutely necessary in the manufacturing of vaccines. In order to produce the best, purest vaccine for all of us you`ll need polished stainless tubes at the inside of tubes. Stainless steel pipes with a high-quality internal grinding are also used for breweries, the food and beverage industry with the highest degree of uniformity.

Inside polished tubes AISI 316TI or 304L are very interesting and important for pipe manufacturers. The above shown seamless stainless stube with 22mm thickness has a very orange peel shaped structured surface.The transport of any kind of fluids gases or other kind medias keeping the products clean and clear is absolutely necessary, especially for the production of vaccines. Inside polished tubes are needed for brewers and food processing machines with the highest uniformity. orresponding standardised measuring tools and measuring protocols are available to meet the high safety requirements.

The hot-finished surface of seamless pipes has an orange peel or a structure similar to a walnut with irregular surface patterns. Processing is carried out using abrasive grinding tools that are customised to the end use of the respective surface.

Seamless stainless steel tubes with an internally polished surface up to Ra <0.11my are also possible with our machinery. This round tube diameter 76.1x6.3mm made of 316L steel was processed by various grinding tools and work processes to an Ra value of Ra <1.0my.
