Frequently asked questions

Our standard lead time is 2 weeks, significantly faster than the industry average of12-20 weeks. We achieve this through modular design and a strategic inventory ofcore components (SS316L bodies, diaphragms). For urgent project needs, pleasecontact our engineering team for "Fast-Track" options.

Every single product undergoes a rigorous Helium Leak Test using ahigh-sensitivity mass spectrometer. We guarantee a leak rate of less than 1x10-3mbar-l/s. A detailed test report with a unique serial number is provided with eachdelivery.

Yes. We hold the CE-PED (Pressure Equipment Directive) certification (NB0036/0035 equivalent). This is not just a general CE mark, but a specific safetycertification for high-pressure equipment, which is a mandatory requirement for 90%of industrial projects in Europe (,, etc.).

We strictly use SS316L (VIM/VAR grade) for ultra-high purity and hydrogenapplications to prevent hydrogen embrittlement. All raw materials come with EN10204 3.1 Mill Test Reports. For corrosive gases, we offer Hastelloy and Elgiloydiaphragm options.

Absolutely. We specialize in "Lego-style" modular customization. Whether it's a70MPa hydrogen manifold or a semi-automatic changeover system for a lab, ourengineers can provide a professional 3D design and technical datasheet within 24-48nours.

Yes, we welcome sample orders. We understand that in the semiconductor andenergy sectors, "seeing is believing." You can test our Ra < 0.25um surface finish andoressure stability before committing to a bulk purchase.
