DN13 PTFE Hose | Corrosion Resistant
DN13 PTFE hose, as a pipe material widely used in industry and scientific research, has become the preferred choice of many engineers and technicians for its unique performance and wide application scenarios. This article will explore the performance, material characteristics, application scenarios and precautions of DN13 PTFE hose under 3Mpa pressure in order to provide readers with a comprehensive and in-depth understanding.
PTFE, or polytetrafluoroethylene, is a synthetic polymer material. The hydrogen atoms in its molecular structure are completely replaced by fluorine atoms, giving it a series of excellent physical and chemical properties. PTFE hose, as an application form of PTFE material, shines in many fields with its excellent chemical stability, high temperature resistance, low friction coefficient and physiological inertness. DN13, as a specification of hose, usually refers to the size of its inner diameter or outer diameter. The choice of this size is often based on the needs of specific application scenarios.

Under 3Mpa pressure, DN13 PTFE hose shows excellent pressure resistance. Generally speaking, PTFE bellows can withstand a pressure of up to 3MPa, but the specific pressure level needs to be determined according to the actual application. This pressure range makes DN13 PTFE hose perform well in high-pressure fluid transmission, chemical reagent delivery and other occasions. Its pressure resistance is not only due to the strength of the PTFE material itself, but also due to the reasonable design of the hose structure, such as the selection of corrugated shape and the optimization of wall thickness. These factors together ensure the stability and safety of the hose under high-pressure environment.
In addition to the pressure resistance, the chemical stability of DN13 PTFE hose is also one of the reasons why it is so popular. PTFE material is almost insoluble in all solvents and can resist the erosion of strong acids, strong alkalis, strong oxidants, reducing agents and various organic solvents. This feature makes DN13 PTFE hose widely used in chemical, pharmaceutical, food processing and other industries. In these industries, fluids often contain corrosive substances, which traditional pipeline materials often cannot withstand, while PTFE hoses can easily cope with it, ensuring the purity and safety of the fluid.
In addition, DN13 PTFE hose also has good high temperature resistance. The long-term use temperature of PTFE material can reach 260℃, and the short-term use temperature is even higher. This feature makes it possible to use DN13 PTFE hose in high temperature environments, such as steam delivery, high temperature oil circulation, etc. At the same time, its low friction coefficient also gives the hose good lubrication properties, reduces the resistance of the fluid in the pipeline, and improves the transmission efficiency.
In the medical field, DN13 PTFE hose also plays an important role. Due to its physiological inertness and non-stickiness, PTFE hose is widely used in tissue repair materials and artificial organ materials such as artificial blood vessels and heart repair membranes. These applications require not only good biocompatibility of materials, but also the ability to withstand certain pressure and tension. With its excellent performance, DN13 PTFE hose has successfully met these requirements and made important contributions to the development of the medical field.
In the aerospace field, DN13 PTFE hose also plays an important role. Aerospace equipment often needs to work in extreme environments, such as high temperature, high pressure, strong radiation, etc. Traditional pipeline materials are often difficult to withstand these extreme conditions, while PTFE hoses have become an ideal choice in the aerospace field with their excellent resistance to high temperature, high pressure and radiation. In key parts such as rocket engines and satellite propulsion systems, the application of DN13 PTFE hoses ensures the stable transmission of fluids and the normal operation of equipment.
However, despite the many advantages of DN13 PTFE hoses, some precautions should be taken during use. First, although PTFE materials have good chemical stability, chemical reactions may occur in certain environments such as strong oxidants, molten alkali metals, and sodium hydroxide solutions at high temperatures, resulting in performance degradation. Therefore, when selecting DN13 PTFE hoses, it is necessary to fully consider their working environment and fluid properties to ensure that the hoses can operate stably for a long time.
Secondly, the installation and use of DN13 PTFE hoses also need to follow certain specifications. During installation, the hoses should be prevented from being subjected to excessive bending and stretching to avoid damage to their structure. At the same time, when connecting the hoses, suitable joints and seals should be selected to ensure the reliability and sealing of the connections. During use, the appearance and performance of the hoses should be checked regularly. If cracks, deformations, or leaks are found, they should be replaced or repaired in time.
In addition, DN13 PTFE hoses also need to pay attention to some issues during storage and transportation. Since PTFE materials are sensitive to ultraviolet rays, long-term exposure to sunlight may cause material aging. Therefore, during storage and transportation, the hose should be avoided from direct exposure to sunlight and corresponding protective measures should be taken. At the same time, during transportation, the hose should be avoided from being squeezed and collided to avoid damage to its structure.
In summary, DN13 PTFE hose has been widely used in many fields due to its excellent performance. Under a pressure of 3Mpa, its pressure resistance, chemical stability, high temperature resistance and low friction coefficient make it the preferred choice of many engineers and technicians. However, some issues still need to be paid attention to during use, such as the selection of working environment, the specifications of installation and use, and the precautions for storage and transportation. Only by fully understanding and following these precautions can we ensure that the DN13 PTFE hose can play its excellent performance stably for a long time and make greater contributions to the development of various fields.
