Double layer steel braided steam hose 4MPa pressure resistant steam hose
Steam transportation is a crucial link, especially in industries such as chemical, petroleum, and food manufacturing, where the pressure resistance and safety requirements for steam hoses are extremely strict. In this context, double-layer steel braided steam hoses have become an ideal choice for filtering and transporting high-pressure steam due to their excellent performance and reliability. This article will delve into the structural characteristics, performance advantages, application areas, and maintenance of double-layer steel braided steam hoses, helping readers to have a more comprehensive understanding of this important equipment.
1、 Structural characteristics of double-layer steel braided steam hose
Double layered steel braided steam hoses are usually composed of an inner layer and an outer layer. The inner layer is made of high-quality synthetic rubber, which can withstand high temperature and high pressure, providing a guarantee for the safe transportation of steam; The outer layer is made of special materials that are wear-resistant and weather resistant, and a steel wire weaving layer is reinforced inside to provide additional strength and pressure resistance for the rubber hose. This double-layer structure not only ensures the stability of the hose in high temperature and high pressure environments, but also prevents the impact caused by external environmental changes.
1. Inner layer material:
The inner layer is usually made of neoprene (CR), nitrile butadiene rubber (NBR) or ethylene propylene rubber (EPDM). These materials have excellent heat resistance and aging resistance and can work stably at high temperatures up to 150 ℃. Meanwhile, their excellent elasticity and stretchability greatly enhance the durability of the rubber hose.
2. Outer layer material:
The outer layer is generally made of wear-resistant and UV resistant polyurethane (PU) or rubber materials to ensure that the hose will not be damaged when used in various harsh environments. In addition, the selection of outer material also takes into account oil resistance and chemical corrosion resistance, adapting to the needs of different industrial occasions.
3. Steel wire weaving layer:
The steel wire braided layer is the core part of the double-layer steel braided steam hose, with a compact structure that greatly enhances the tensile strength and pressure resistance of the hose. The design of the gap between the braided steel wires ensures that the rubber hose remains stable and not easily deformed even when twisted or twisted.
2、 Performance advantages of double-layer steel braided steam hose
The main advantages of double-layer steel braided steam hoses are reflected in the following aspects:
1. Voltage resistance performance:
Its pressure tolerance can reach up to 4.0MPa (40kgf/cm ²), which is suitable for most industrial steam transportation needs. When transporting high-pressure steam, it can effectively prevent hose rupture or leakage, ensuring production safety.
2. High temperature resistance performance:
Even at temperatures as high as 150 ℃, double-layer steel braided steam hoses can maintain excellent flexibility and strength, ensuring no brittle cracking during operation and improving equipment reliability.
3. Excellent flexibility:
Despite its high strength, the double-layer steel braided steam hose still maintains good flexibility, can adapt to complex industrial environments, and is easy to install and place.
4. Corrosion resistance:
The special material selection enables this hose to resist corrosion from various chemical media and is suitable for use in a variety of chemical environments.
3、 Application fields of double-layer steel braided steam hose
Double layered steel braided steam hoses are widely used in multiple industries, and the following are some of the main application areas:
1. Chemical industry:
In chemical plants, steam is widely used as a heating and reaction medium, and double-layer steel braided steam hoses are very suitable for use in these environments due to their high temperature resistance, corrosion resistance, and other characteristics.
2. Food manufacturing:
In the food industry, the hygiene and safety requirements for conveying equipment are extremely high. Qualified double-layer steel braided steam hose ensures the transportation of high-temperature steam without causing contamination to food.
3. Pharmaceutical industry:
The environmental hygiene and material safety requirements are extremely strict during the pharmaceutical process. The double-layer steel braided steam hose can ensure the purity and temperature of the steam well, ensuring the efficiency of the pharmaceutical process and the quality of the product.
4. Construction industry:
In construction, steam is often used for heating, concrete curing, and other processes. Double layered steel braided steam hoses have become the preferred conveying material in the construction industry due to their good pressure resistance and flexibility.
4、 Maintenance and upkeep
Although the performance of double-layer steel braided steam hoses is excellent, regular maintenance and upkeep are still essential during use. Here are some basic maintenance suggestions:
1. Regular inspection:
Regularly conduct a comprehensive inspection of the rubber hose to observe for any signs of external damage, wear, or aging, and promptly replace damaged parts to avoid accidents.
2. Avoid excessive bending:
During installation, excessive bending or twisting of the hose should be avoided, as this can affect its normal fluid transport function and may also cause damage to the hose.
3. Avoid exposure to extreme environments:
Although double-layer steel braided steam hoses have good temperature and pressure resistance, prolonged exposure to extreme high or low temperature environments may still have a certain impact on their performance.
4. Proper storage:
When not in use, the rubber hose should be stored properly, avoiding direct sunlight and moisture to maintain its long-term performance.
In summary, double-layer steel braided steam hoses have become an indispensable and important component of modern industry due to their excellent pressure resistance, high temperature resistance, and wide range of applications. With the continuous development of technology, future steam hoses will usher in more innovation and progress, providing a more solid guarantee for the steady development of various industries.
