Featured products certified for heavy-duty material handling in maritime port terminals, mining pits, and cement production facilities across Portugal.
Portugal is experiencing a structural modernization across its heavy industrial sectors. Driven by the European Green Deal and strict national environmental regulations, industries such as cement manufacturing (Cimpor, Secil), deep mining (Neves-Corvo, Aljustrel), and maritime logistics terminals (Port of Sines, Port of Leixões) are moving away from traditional open conveyor systems to cut down on dust emissions, avoid material loss, and lower operational carbon footprints.
Enclosed pipe conveyor belts have become the preferred technical solution for modernizing these operations. By wrapping the conveyed materials in a sealed cylindrical rubber tube, pipe conveyor systems prevent fine particles of coal, clinker, ores, and woodchips from leaking into nearby ecosystems. This is especially critical in agricultural zones and tourist areas across Portugal, such as Setúbal and Alentejo, where environmental compliance is closely monitored.

A deep look into the structural physics and formulation technology that enable pipe conveyor systems to operate efficiently over long distances.
Operating a pipe conveyor belt involves complex dynamic stresses. Unlike flat belts, a pipe belt must maintain a stable cylindrical shape while running, resist collapse along curves, and open flat at head and tail terminals. This requires specialized carcass design and compounding to ensure the right balance between transverse stiffness and longitudinal flexibility.
Our engineering team adjusts the carcass construction using high-modulus EP (Polyester-Polyamide) fabrics or premium steel cords. This provides the lateral stiffness needed to keep the belt round, preventing collapse under load while keeping the overlap seal tightly closed between support idlers.
To reduce power consumption at high-throughput port terminals, we use custom-developed viscoelastic rubber compounds. These compounds reduce indentation energy loss as the belt rolls over idler rollers, saving up to 12% to 18% in power consumption compared to standard rubber cover grades.
Our pipe belts undergo strict testing to verify their ozone and fatigue resistance. Because the belt is constantly flexing through transition zones, the rubber must resist cracking and ply separation over millions of cycles, ensuring a long service life under harsh maritime and industrial conditions.
| Property Parameter | DIN 22102 Standard Requirement | Jinao Brand Performance (Boao Group) | Engineering Benefit |
|---|---|---|---|
| Tensile Strength (MPa) | ≥ 18 MPa | 20 - 24 MPa | High safety factor under peak startup tensions | Elongation at Break (%) | ≥ 350 % | ≥ 400 % | Prevents micro-cracks under high flexural fatigue |
| Abrasion Loss (mm³) | ≤ 120 mm³ (DIN Y) / ≤ 90 mm³ (DIN W) | ≤ 75 mm³ | Extends life when handling abrasive materials like slag & clinker |
| Overlap Stability | Subject to local alignment | Self-correcting edge geometry | Minimizes structural twist on long-distance curves |
