Maintenance and diagnostics for industrial cylinders
Enrico Zanini
When it comes to industrial plants, cylinders are the beating heart of production. Yet, unexpected machine downtime or a quality defect can result from invisible wear that escapes routine checks. This is precisely why A.Piovan has developed an approach that goes beyond simple re-rubberization: a comprehensive mechanical overhaul and advanced diagnostics protocol that guarantees the complete integrity of the component.
Entrusting a cylinder to A.Piovan also means you can count on a complete mechanical overhaul service. Thanks to its consolidated experience and a qualified network of partner workshops, the company supports customers in the mechanical overhaul of cylinders, ensuring precise tolerances that make the difference in terms of performance and durability.
Maintenance Services
- Bearing seat overhaul and restoration: Pin wear analysis is the starting point. A.Piovan reconstructs the seats through metal coatings and precision grinding, restoring the component to its original specifications.
- Pin repair or replacement: The pin is the most stressed element of the entire cylinder. The technical team proceeds with restoration work through galvanization and grinding or, in cases of structural damage or breakage, with the complete replacement of the component.
- Dynamic balancing: Eliminating residual vibrations is not a minor detail, it is a fundamental requirement to preserve the useful life of machinery and ensure consistent production even at the highest operating speeds.
- Magnetic particle inspection (MT): Particularly suitable for ferromagnetic components, magnetic particle inspections allow for the precise identification of surface and subsurface discontinuities that could compromise structural integrity.
- Liquid penetrant testing (PT): This technique is essential for verifying the integrity of non-porous surfaces. The test accurately highlights porosity, cracks, or welding defects that may not be visible to the naked eye.
- Dimensional and eccentricity checks: Using certified measuring instruments, A.Piovan ensures that each cylinder strictly complies with the customer's technical drawings, checking critical parameters such as runout and cylindricity.
A.Piovan's approach stands out for its ability to offer a comprehensive service that integrates re-rubberization and mechanical maintenance into a single workflow. This synergy allows maintenance managers to optimize intervention times and receive fully overhauled components, ready to guarantee maximum performance
