Description

At the sale, the tube is cut at the customer’s indication with length +/- 1 mm. Cutting step 10mm. Max. length of cutting is defined on the max. length of the available in the stock ( shown in the tec. characteristics).

Cold drawn seamless precision tubes made by steel are used in the repair and production of shells for hydraulic cylinders with standard charge.

The advantage of the precision tubes is the high accuracy of their productions, better surface quality, more types of measurements, guaranteed mechanical and technical characteristics.
