A Comprehensive Analysis of the Models and Specifications of Tubular Conveyor Belts
2025,09,18
In industries such as metallurgy, power, and chemical engineering, tubular conveyor belts are increasingly widely used due to their ability to achieve closed material transportation. They come in various models and specifications, providing suitable solutions for different working conditions.
In terms of pipe diameter and belt width, common pipe diameters range from 100mm to 850mm, corresponding to belt widths from 400mm to 3150mm. For instance, a 150mm pipe diameter is typically paired with a 600mm belt width. According to the HG/T4225 - 2011 standard, specifications are marked with details such as pipe diameter, width, and the number of belt core layers. For example, "1000 NN 4 8 4+2+2 L" indicates a width of 1000mm, a 4-layer nylon core, and an upper cover thickness of 8mm, etc.
Regarding fabric cores, nylon canvas cores are common, with models ranging from NN - 100 to NN - 300, corresponding to different minimum roller diameters. The number of layers varies, and the suitable roller diameters also differ. For example, a 2-layer NN - 100 type belt is suitable for a 200mm roller. steel cord core specifications are classified by longitudinal tensile strength, ranging from ST 630 to ST 5400. Different strengths result in variations in steel wire diameter, spacing, and cover thickness. When enterprises select models, they need to comprehensively consider factors such as material characteristics and transportation distance to precisely match and ensure efficient transportation.
