Buyer Guide
Frequently Asked Questions for Kópavogur Procurement Teams
Addressing practical engineering constraints, logistical realities, import duties, and thermal characteristics for sourcing clear quartz in Iceland.
How do clear quartz tubes withstand geothermal gases rich in H₂S and silica?
Fused quartz consists of ≥99.99% crystalline silica, rendering it completely inert to hydrogen sulfide (H₂S), sulfur dioxide (SO₂), carbon dioxide (CO₂), and concentrated acids (with the exception of hydrofluoric and boiling phosphoric acids). Unlike soda-lime or borosilicate glass, it will not experience alkaline leaching, clouding, or embrittlement under continuous geothermal vapor exposure.
What is the distinction between fused quartz and synthetic fused silica?
Fused quartz is produced by melting natural high-purity quartz crystal sand in high-temperature electric arc furnaces; synthetic silica is synthesized via chemical vapor deposition (CVD) of SiCl₄. For virtually all geothermal sight glasses, furnace envelopes, and photobioreactors in Kópavogur, fused quartz provides unmatched mechanical strength and 1,100 °C heat resistance at a significantly lower procurement expense.
What are the lead times and shipping routes for fragile quartz tubes to Iceland?
Standard prototypes or small batches are dispatched via DHL/FedEx Express directly to Keflavík International Airport within 5–7 transit days. Bulk industrial orders (such as large-diameter tubes or full container loads of sight glass plates) ship via ocean freight to the Port of Reykjavík/Sundahöfn within 30–38 days. Each unit is suspended in customized high-density shock foam inside export crates.
Can you manufacture quartz tubes according to custom CAD drawings with ground joints?
Yes. We specialize in custom flame-working and CNC cold finishing. We produce clear tubes with flared ends, domed/flat sealed bottoms, standard taper joints (ST), spherical ball joints, and ISO/KF-style quartz flanges manufactured to dimensional tolerances as tight as ±0.05 mm.
What tube outer-diameter (OD) range is available from your Donghai factory?
Our standard drawing facilities produce continuous clear tubes from miniature 2 mm capillary lines up to 500 mm OD heavy-wall industrial columns. Through our provincial scientific R&D achievements, we also supply ultra-large 520 mm semiconductor-grade quartz core tubes for high-temperature diffusion applications.
What technical criteria should we specify when requesting a quote for Kópavogur?
To receive an expedited and accurate technical proposal, provide: 1) Outer diameter (OD), inner diameter (ID) or wall thickness, and total length; 2) Required dimensional tolerance; 3) Operating temperature and pressure/vacuum level; 4) Working atmosphere (chemical reagents or geothermal vapors); and 5) End finish (fire-polished, ground flat, or flange-coupled).
