products & developments Seamless tubes cut component costs

ray measuring systems to monitor outer diameter and the wall thickness of tubes, and eddy current testing to detect surface cracks. Ovako’s stock programme for bearing grade steels covers 350 tube sizes from OD 30 to 250mm. Carbon hollow bar (EN10294) is stocked in 250 sizes in the same diameter range. Wall thicknesses range from 3 to 50mm. The wide range of standard sizes means that customers can quickly achieve a close match to their stock requirements. The tube is supplied either in random lengths or to fixed lengths between 1.8 and 9m, within tight tolerances. As well as supplying lengths of tube, Ovako has responded to growing demand for pre-machined or completely finished components, either as long or short runs. This service, backed by an investment in flexible manufacturing systems, is capable of fast turnaround to reduce customer stockholding, cutting and machining. Ovako’s production is based on recycled steel, and includes steel in the form of bars, tubes, rings and pre-components. The company is represented in more than 30 countries and has sales offices in Europe, North America and Asia.

starting point is the production of high quality steel with consistently low levels of oxygen. Modern precision rolling techniques are used to convert the steel into a wide range of hot rolled, cold rolled or cold drawn seamless tubes, as well as hot rolled peeled tubes and cold rolled or drawn centreless ground tubes. Each tube size has to meet precise tolerances, designed so that only minimum machining is needed by customers. The target is to enable clean, cylindrical ring dimensions to be achieved in a single cut. Ovako aims for zero defects in its production processes. Automated inspection equipment includes laser and gamma

A European steel producer’s ability to supply seamless tube to very fine tolerances straight from the mill is helping to bring down component costs for customers in the automotive and engineering industries. Ovako, a producer of hot rolled and cold worked seamless tubes, has invested heavily in plant and procedures to enable it to manufacture tube to guaranteed dimensions, so customers are able to reduce machining, improve yields and cut costs. The company has achieved this by controlling the production process from steel melt to finished tube. The

Simplifying pipe stress complexity Specialising in piping design and stress analysis software solutions and services, SST has introduced Caepipe v7.0 on its 30 th anniversary. pump/compressor/turbine reports for ten operating cases; and operating stresses for non-destructive examination (NDE) purposes.

PDS, SmartPlant 3D, ProCAD, Caesar II, Pipepak and many others. SST Systems, Inc was founded in 1983, dedicated to providing a complete solution to piping design and analysis requirements for engineers in the process, energy, aerospace and related industries. The company offers software solutions and services for piping design, stress analysis and integrated plant management.

Caepipe software for rapid pipe stress analysis of any complexity is used not only in traditional applications such as power generation, district heating and petrochemical, but also on advanced fighter aircraft, the Space Shuttle and on submarines. Using the optional translators, piping data can be imported from AutoCAD Plant 3D, CATIA, PDMS,

Caepipe now adds more power and flexibility to its processing engine. New features in addition to the standard statics, dynamics and piping code compliance include ten thermal loads; four wind loads; 2012 ANSI/ ASME B31 and European EN codes; 95+ load cases; expansion stresses for 50+ thermal ranges; support load summary for 150+ load combinations;
