RFQ
1. What pressure ranges do your metal hoses cover?
We manufacture hoses for pressures from vacuum (10⁻⁸ Torr) to ultra-high pressure (1,500 bar/21,750 psi), with standard options covering PN16 to PN420 ratings.
2. What materials are available for corrosive applications?
Our standard 316L stainless steel handles most chemicals, while specialty options include Hastelloy C-276 for acids, Inconel 625 for caustics, and titanium for seawater service.
3. How do you ensure leak-free performance?
All critical welds are orbital TIG welded and 100% helium leak tested to 1×10⁻⁹ mbar·L/s, with metal-to-metal seals for extreme conditions.
4. What temperature limits can your hoses withstand?
Standard range: -269°C to +800°C. Special configurations with ceramic insulation or refractory metals reach 1,200°C continuous service.
