2021 High quality 3 Inch Hdpe Pipe Roll - HDPE Optical fiber cluster tube – HONOUR SHINE

Product description
• HDPE cluster tube is a new type of micro-cable protective sleeve, which combines 7-hole 25/21 sub-tubes in a certain way. The outer layer is composed of a 3.0mm high-density polyethylene sheath, which can be accommodated in a limited space. More tube holes and protection of sub-tubes.

Main Specifications
• The sub-pipes should be made of high-density polyethylene (HDPE);
•The inner wall of the sub-pipe adopts longitudinal guide groove or silicon coating to improve blowing efficiency (longitudinal guide groove and silicon coating can also be used at the same time);
• The appearance colors of the sub-pipes are distinguished by 7 kinds of colored pipes, so as to meet the quality standard of non-doped recycled materials. The inner and outer wall entities should be flat, uniform and smooth, free of collapse, holes, tear marks, impurity pits and other defects. No bubbles or cracks;
• Mechanical properties of the sub-tube: tensile yield strength ≥18MPa; elongation at break ≥350%; pressure 25bar; minimum bending radius 144mm, maximum traction load 735n.

Outer protection tube
• The outer protective tube should be made of high-density polyethylene (HDPE);
• During the bunching process, no damage to the outer wall or structure of the sub-pipe shall be caused;
• The inner and outer walls of the pipe should be smooth, flat, clean, and no bubbles, cracks, significant dents, impurities, etc. are allowed. The cross section of the pipe is uniform. The inner and outer layers of the outer protective pipe should be tightly welded, and the appearance of the color is uniform. The above product identification is complete;
•Mechanical properties: tensile yield strength ≥18MPa, elongation at break ≥350%;

Pipeline characteristics
The outer wall of the pipeline adopts a flat-walled solid-walled pipe with a wall thickness of 3.0mm to achieve higher ring stiffness and ring flexibility.

The inner wall of the pipeline is made of a solid silicon lubricating layer. In simple terms, the cluster tube has the following five advantages compared with traditional pipes. Although the inner wall of the cluster tube is a silicon core layer, it is a solid lubricant with a small friction coefficient. Ensure that the inner wall is smooth, and the pipeline transmission loss is 30% lower than that of the steel pipe. The structure of the cluster tube is excellent. The silicon core layer of the cluster tube is evenly coated on the inner wall of the HDPE through high pressure, so that the two can be well integrated into a whole, and there is no distinction between inner and outer layers, and will not be peeled off. The cluster tube is light in weight and easy to install. The matrix of the cluster tube is HDPE synthetic resin layer, and its chemical composition is HDPE. Compared with similar pipes, the quality is only one-tenth, which is convenient for transportation and storage. The cluster tube has the strength, rigidity and compression resistance of ordinary pipes, can well protect the silicon core layer inside, and has tensile resistance similar to steel. The inner wall of the cluster tube is made of solid silicon material, which has very good flame retardancy, insulation, corrosion resistance and acid and alkali resistance.
