Tube tapering is a mechanical process that makes it possible to reduce or modify the diameter of a tube, creating customised geometric shapes for technical, aesthetic or functional applications. It is an essential process in sectors where components are designed to fit joints, connectors or complex metal structures.
Siera utilizes dedicated plastic deformation machinery to process stainless steel, aluminium and other materials, in line with the required tolerances. The result is a uniform and controlled tapering.
The solutions offered meet the needs of the main industrial sectors:
Thanks to the combination of technical know-how and dedicated equipment, the Siera team is able to manage both simple tapering operations and complex processes, always ensuring high process repeatability.
Tube flaring is one of the most requested processes when it is necessary to reinforce the tube end, create a support surface or prepare the piece for assembly with other components (such as ogives). This operation makes it possible to obtain regular, burr-free edges, increasing both safety and functionality.
Siera performs flaring with different angles and radii, configuring the tube based on the customer’s project. Our techniques include:
The use of modern machinery ensures controlled deformation and consistent quality even on difficult materials such as stainless steel. Flaring can be combined with tapering, cutting, bending or satin finishing, enabling the production of a finished component ready for assembly.
Relying on Siera for tube deformation and flaring means collaborating with a partner capable of guaranteeing high standards and a personalised approach. The main advantages include:
The processes are engineered and carried out in compliance with the required tolerances.
Siera works with various metals:
Thanks to their experience, Siera operators configure each process according to the specific deformation parameters of every material.
The in-house tube division – which includes cutting, bending, welding, satin finishing and polishing – makes it possible to manage a project completely, reducing logistical steps for the customer and achieving greater aesthetic and functional uniformity.
Whether for a single prototype or industrial production, each phase is customised based on the technical drawing provided or developed jointly.
Siera has been operating for over 40 years in the metalworking sector, with a fully equipped department dedicated to tubular deformation. The approach is based on three key principles: quality, consultancy and production continuity.
Highly specialised personnel and ongoing training allow the execution of complex processes while meeting the standards required by the most demanding industries.
The use of specific equipment allows tube deformation while maintaining concentricity, regularity and linearity of the surface.
Clients are supported in selecting the most suitable solution to achieve the deformation geometry required.
Every process is monitored in each phase, guaranteeing maximum repeatability and compliance with the technical drawing.
Thanks to a full service offering, Siera can deliver a finished, assembly-ready product, reducing time and production costs for the customer.
The stainless steel tube tapering process follows a precise sequence designed to preserve the material’s mechanical properties and achieve the required shape:
When correctly deformed, stainless steel maintains its original strength and excellent corrosion resistance, making the process ideal for food-grade, aesthetic and industrial applications.
Tubular deformation requires equipment designed to ensure proper execution. Siera’s production machinery enables:
This technology ensures to realize components suitable for integration into the final project.
The role of the specialised operator is essential to ensure the high-quality standards that characterise every Siera process. Experience enables the operator to:
The result is a customised, functional tube ready to be incorporated into the final project.
