Learn More >Namibia's industrial economy is significantly anchored on extractive mineral resources, heavy manufacturing, and maritime logistics. The vast deserts and coastal conditions impose harsh, dry, high-abrasive, and corrosive environments on machinery operations. Sectors such as Uranium mining (e.g., the massive Rössing and Husab Open-Pit mines), Gold mining (Otjikoto), Copper processing (Tschudi), and Marine Diamond dredging require heavy-duty equipment to work continuously without catastrophic failure. Mechanical components like excavator buckets, dragline chutes, hopper linings, and mill cyclones encounter severe abrasive and impact wear from silica-rich sands and rock fragments.
Traditional structural steels (Q235, Q345, or equivalents) undergo rapid wear under the severe quartz-heavy soils of the Erongo and Otjozondjupa regions. Without protective hardfacing layers, key machinery experiences downtime and excessive maintenance costs. Implementing Chromium Carbide Overlay (CCO) Wear Plates and applying hardfacing flux-cored welding wires has emerged as the premier strategy to extend component lifespan, reduce downtime, and improve overall mining operational efficiency (OEE) across Namibia.
Global procurement teams targeting Sub-Saharan Africa demand strict adherence to quality parameters. Welding wires and CCO plates must meet international standards such as DIN 8555 (e.g., MF10-GF-60-GR) to guarantee performance consistency. Industrial operators in Namibia prefer partnering directly with integrated factories that can supply custom chemistry modifications, offer robust wear calculations, and manage comprehensive export logistics directly to major destinations such as Windhoek, Swakopmund, and the Port of Walvis Bay.

Tangshan Runxing Machinery Co., Ltd. is an established, specialized manufacturer headquartered in Tangshan, Hebei Province, focusing on the research, development, manufacturing, and on-site deployment of hardfacing wear-resistant metal components since its foundation in 2010.
Our comprehensive production spectrum includes Chromium Carbide Overlay (CCO) wear plates, customized wear liners, wear-resistant pipelines and fittings, hardfacing flux-cored welding wires, automatic surfacing machinery, and expert mill roll refurbishment services. Driven by the philosophy of "Integrity, Superior Quality, Innovation & Sustainable Development," we possess mature and cutting-edge surface hardfacing metallurgy.
To support international clients, all export and trading activities are fully managed and cleared by Hebei Yuwan International Trade Co., Ltd. This strategic division allows our manufacturing site to focus entirely on metallurgical quality control and precise production cycles, while ensuring seamless logistical handling, international payment options, and customs clearance procedures for Namibian mining and industrial clients.
Maximized uptime of vertical mills and separator screens. Our wear plates prevent downtime in Namibian cement production.
Providing wear liners and high-carbide welding wire for open-cast copper, uranium, and gold mining operations.
Withstanding high temperatures, raw minerals, and continuous abrasive impact on material guide plates.
Wear protection for fan blades, fuel transport systems, and hopper chutes in localized power generating stations.
Corrosion-resistant hardfacing alloys for hopper dredgers and ship-unloader liners working at coastal ports.
Sintered, high-purity alumina options when lightweight, chemical corrosion-resistant wear shielding is required.
We continue to optimize alloy formulations to match changing mineral profiles, environmental temperatures, and industrial machinery dynamics worldwide.
Our hardfacing flux-cored wires incorporate high concentrations of Chromium (Cr) and Carbon (C). During welding, they form primary chromium carbides of the M7C3 type, embedded within a tough, impact-resistant eutectic matrix. The microscopic hardness of these carbides ranges between 1200 - 1600 HV, while the bulk overlay maintains a macro-hardness of 58 - 62 HRC. This microstructure is particularly effective against 3-body abrasive wear, preventing high-velocity sand particles from scoring the underlying parent steel plate.
Purchasing directly from Chinese factories can sometimes present importing and logistical barriers. Runxing overcomes this via Hebei Yuwan International Trade Co., Ltd. We handle all sea freight booking, export documentation matching Namibia Standards Institution (NSI) requirements, and coordinate inland shipping from the Port of Walvis Bay to the inland mining centers. This structured process guarantees that high-wear parts and heavy welding consumables arrive directly at your site on time, bypassing customs delays.

Why is self-shielded flux-cored wire preferred for Namibian mine maintenance?
Namibia's open-pit mines are frequently subjected to high desert winds, which disperse conventional gas shielding (like Argon/CO2). Runxing's self-shielded flux-cored wires feature integrated fluxing agents that generate their own protective atmosphere upon burning, ensuring clean, defect-free welds even in windy, outdoor environments.
How does Runxing CCO wear plate stand up to coastal salinity in Walvis Bay?
Our bimetallic CCO plates integrate high levels of chromium, which forms a dense, passive chromium oxide layer. This layer resists both severe particulate abrasion and chemical oxidation caused by marine salt air, delivering longer life than carbon steel or traditional quench-and-tempered plates.
What is the typical shipping lead time from China to Namibia?
Sea shipment from Chinese ports to Walvis Bay generally spans 35 to 45 days. Our partner Hebei Yuwan International Trade coordinates the shipping documentation, customs clearance, and inland routing to guarantee a trouble-free process.
