High-precision steel tubing for gas springs, hydraulics and industrial actuation systems.
The alternative to seamless tube that cuts cost without sacrificing performance.
Fabricamos tubo de acero soldado de alta precisión con interior espejo para la industria de ingeniería: gas springs, cilindros hidráulicos, actuadores neumáticos y mecanismos de cierre. Prestaciones técnicas equivalentes al seamless, con coste de tubo soldado de precisión y plazos predecibles.
Seamless tube is still more expensive than it needs to be.
El tubo extrusionado sin soldadura lleva décadas siendo el estándar en ingeniería de precisión interior. Su argumento histórico: sin costuras interiores. Pero ese argumento tiene un coste oculto que muchos ingenieros y responsables de compras no han cuantificado. La gama PRECISE de Delmàs ofrece el mismo rendimiento técnico a un coste muy inferior — con previsibilidad en las entregas.
Without PRECISE range — with seamless tube
- Cost 30% to 80% higher than the equivalent precision welded tube
- Uncertain and unpredictable lead times in non-catalogue diameters
- In diameters under 25 mm, availability is scarce and MOQs are high
- In non-standard diameters: unavailable or with unworkable minimum quantities
- The technical advantage of "seamless" is not necessary in low pressure
- Real life-cycle cost is significantly higher than the purchase price
With the Delmàs PRECISE range
- Mirror bore technically equivalent to seamless (EN 10305-2)
- Precision welded tube pricing: direct savings of 30% to 80%
- Predictable availability and tailored supply chains
- Diameters 8–25 mm, including non-standard sizes on request
- Already replaces seamless in gas springs, hydraulics and mechanical engineering
- Savings accumulate: order by order, month by month
We manufacture for every subsector where the tube bore is the determining factor.
Low-pressure hydraulics and gas springs are the two applications where seamless tube replacement is most direct and the savings most quantifiable. The tube bore is the piston's working surface: it must be perfect.
Precision pneumatic actuators, high-precision guides and demanding mechanical assemblies require the dimensional control that only the PRECISE or OPTIM range can provide in welded tubing.
Closure mechanisms, security doors and industrial shutter systems require the precise dimensional fit that the OPTIM range guarantees. Electrical engineering uses PREMIUM tubing as finished-surface cable conduit.
