1. Manufacturing process of PEX pipe
The manufacturing process of PEX pipe mainly includes the steps of raw material preparation, extrusion molding, radiation crosslinking and follow-up treatment.
Raw material preparation: High-density polyethylene (HDPE) is selected as the main raw material, and an appropriate amount of auxiliary raw materials, such as antioxidants, are added to ensure the stable performance of the pipe.
Extrusion molding: The evenly mixed raw materials are fed into the extruder and extruded into uncrosslinked pipes through the mold. In this process, the size, wall thickness and surface quality of the pipe must be strictly controlled.
Radiation cross-linking: The extruded uncrosslinked pipe is placed on the radiation device, and the radiation cross-linking is carried out by high-energy rays, so that a stable chemical bond is formed between the molecular chains of the pipe, thereby improving the performance of the pipe.
Follow-up treatment: Cutting, flaring, inspection and other follow-up treatment of the cross-linked pipe to ensure that the quality of the pipe meets the standard.
2.The material characteristics of PEX pipe
Excellent temperature resistance: PEX pipe can be used in a wide temperature range of -70℃ ~ 110℃, and has good thermal stability.
Excellent thermal insulation performance: PEX pipe has low thermal conductivity, which can effectively reduce heat transfer and improve thermal insulation effect.
Environmental performance: PEX pipe does not contain harmful substances, can be recycled, in line with environmental requirements.
Excellent chemical properties: PEX pipe has good chemical corrosion resistance and can resist the erosion of a variety of chemical substances.
Good shape memory recovery performance: PEX pipe can be quickly restored to the original state after external force, with good vibration resistance and impact resistance.
To sum up, PEX pipe has a wide application prospect in the engineering field because of its unique manufacturing process and excellent material properties. With the continuous progress of science and technology, the performance of PEX pipes will be further improved to provide more reliable and efficient pipeline solutions for various projects.
