High-reliability pipe conveyor solutions and critical system components engineered for extreme Arctic operating parameters.
Sweden stands at the forefront of the global transition toward fossil-free mining and zero-emission raw material production. Major domestic entities in the Norrbotten and Västerbotten industrial zones—such as LKAB at Kiruna (the world’s largest underground iron ore mine) and Boliden's massive copper extraction sites—are enforcing strict environmental mandates. In this context, conventional open troughed conveyors are increasingly being replaced by advanced pipe conveyor systems.
Unlike standard belts, pipe conveyor belts transition from a flat profile to a sealed cylinder immediately after loading. This design addresses Sweden's two most critical bulk handling challenges: total environment encapsulation (eliminating hazardous fugitive dust emissions) and insulation against high-latitude climates (preventing material freezing, snow accumulation, and roller icing during Sub-Arctic winters).
Engineered rubber compounds and structural reinforce mechanisms designed to operate under sustained tensile stress and dynamic fatigue.
| Parameter Class | Fabric Reinforcement (EP/NN) | Steel Cord Core (ST Class) | Nordic Custom Cover Grade (Low Temp) |
|---|---|---|---|
| Nominal Tensile Strength | 400 N/mm to 3150 N/mm | ST 500 to ST 5400 N/mm | Optimized for elastic strain recovery |
| Pipe Diameter (mm) | Ø 150 – Ø 700 | Ø 250 – Ø 850 | Maintains strict tube geometry stability |
| Forming Elastic Index | Transverse rigidity grade B & C | High-modulus dynamic spring-back | Formulation: Polybutadiene (BR) + NR blend |
| Abrasion Loss (ISO 4649) | ≤ 90 mm³ (Extra wear-resistant) | ≤ 70 mm³ (Swedish rock & slag grade) | Custom options down to ≤ 50 mm³ |
| Working Temp Range | -40°C to +80°C | -55°C to +90°C (Polar duty) | Maintains flexing properties without embrittlement |
Operating out of our Boye County facility spanning over 30 acres, Hebei Boao Rubber Technology Co., Ltd. produces premium conveyor belts sold under our flagship "Jinao" brand. We utilize a highly integrated manufacturing process—from raw polymer compounding to high-pressure vulcanization. This enables us to export durable bulk-handling solutions directly to major European ports, servicing Scandinavian distributors and mines.
Our Quality Assurance system includes an on-site chemical analysis lab and a physics testing suite. Every batch of rubber compound is evaluated for rheology properties, ultimate tensile strength, heat aging characteristics, and low-temperature elastic recovery. These steps ensure our products meet or exceed Swedish industrial requirements prior to shipping.
Proof of reliability through demanding real-world applications in heavy industries, steelworks, and ports.
Ensuring dimensional accuracy, optimal vulcanization, and material properties through automated process control.
