The tubes for mechanical applications are suitable for machining by turning or CNC equipments. The wide size range available, with O.D. from 21.3 to 812 mm, gives the possibility to manufacture several kinds of components for different applications: small machine parts, flanges, fittings, Archimedean screws, hydraulic cylinders for heavy machines etc.

The compliance to the norm EN 10210-1/2 allows the product application for structural purposes as well. This norm is harmonized according to the European Regulation 305/2011 regarding the construction products; therefore the tubes are approved with the relevant CE mark. The size range of hot rolled tubes offers higher wall thicknesses in comparison to the welded hollow sections. For more information, please check also our catalogue “Structural tubes and bars”

The hot rolled mechanical tubes contemporarily satisfy different product norms, making them suitable for different applications: mechanical engineering, structures and hydraulic purposes. In particular this product is supplied with triple marking: E355-EN10297-1(mechanical) / S355J2H-EN10210 1/2(structural) / P355N(TC1)-EN 10216-3(pressure purposes). The product is alternatively available with marking E355K2 EN10297-1 / P355NL1 or P355NL2 (TC1)-EN 10216-3. For both solutions the delivery condition +N, normalized or normalized formed, grants high impact properties to the product.

The compliance to the norm EN 10216-3 allows the product to be used also in the fabrication of components subject to inside pressure, such as hydraulic cylinders, joints, valves, flanges and general piping. We remind that the norm EN 10216-3 is harmonized according to the European Directive 2014/68/UE, which regulates the pressure equipments.

STEEL GRADES: Our standard stock of mechanical tubes consists of the following steel grades E355/S355J2H/P355N, E355K2/ P355NL1/P355NL2, E470, E420J2, E460K2 and E590K2. It is possible to supply material in all existing steel grades stated in this catalogue, upon request and with a minimum quantity according to mill conditions

SIZES: All the standard sizes according to the norm and stated in the table “Sizes, tolerances and masses” are to be considered as normal stock supply. It is possible to supply also special sizes upon request and with a minimum quantity to be agreed.

CERTIFICATES AND MARKINGS: Mill test certificates (3.1 EN 10204) can be supplied with all deliveries. All tubes in random lengths are marked with manufacturer logo, steelgrade and norm, size and traceability reference. In case of tubes in fixed lengths, SICAM applies its identifying labels.

TOLERANCES: The tolerances to be applied on all supplied tubes are stated by the reference norm. Upon request it is possible to arrange special supplies for tubes with more restricted tolerances.

CUTTING TO FIXLENGTH: All tubes for mechanical applications can be supplied cut to fixlength, the quick delivery and the quality of the service are granted by modern automatic cutting machines with band saws. The standard tolerance on fixlength is – 0 / + 5 mm, more restricted tolerances can be agreed at the moment of the order.
