HESPER
Engineered to mitigate pipeline thermal contraction, misalignment, and structural vibrations in deep-sea intakes and heavy mineral processing plants.
Namibia's industrial landscape represents one of the most demanding environmental challenges globally. From the hyper-arid coastal zones of Swakopmund and Walvis Bay to the inland processing mines of Tsumeb and Otjiwarongo, piping infrastructure is exposed to intense environmental stressors.
Thermal expansion and contraction are amplified by temperature differentials exceeding 30°C in less than 12 hours. Piping systems must accommodate these cyclic thermal displacements without experiencing structural fatigue, flange leaks, or anchor failures.
Furthermore, with Namibia's critical focus on Uranium and Copper extraction, industrial piping frequently transports corrosive leach solutions, sulfuric acid, and abrasive ore slurries. Our specialized PTFE-lined expansion compensators and highly reinforced metallic bellows provide the crucial mechanical dampening and acid resistance required to keep your processing plants online.
For installations near Walvis Bay, we enforce the utilization of Duplex Stainless Steel (e.g., SS2205) or marine-grade EPDM for expansion joints to resist chloride stress corrosion cracking caused by salt spray and coastal fog.

The choice depends on the temperature, pressure, and the medium being transported. Rubber joints offer superior sound and vibration isolation and are highly resistant to abrasive slurries, making them ideal for raw mine runoff and hydrocyclones. Metallic bellows, however, are required when temperatures exceed 115°C or in high-pressure steam and gas lines.
Yes. We routinely manufacture and drill flanges to match ANSI B16.5, DIN EN 1092-1, BS10 Table D/E, and AS2129 specifications, ensuring seamless drop-in compatibility with legacy piping systems across Southern Africa.
Absolutely. Virgin PTFE exhibits near-universal chemical inertness. Our PTFE expansion compensators are rated to handle up to 98% concentrated sulfuric acid and other corrosive leaching acids without degradation.
Ocean transit from Chinese main ports (Qingdao, Tianjin, Shanghai) to Walvis Bay Port typically spans 30 to 45 days. We oversee all shipping documentation, export packing (seaworthy wooden cases), and coordinate customs-ready invoicing to ensure smooth clearance.
