The difference between coated pipe and corrugated pipe

Different 1. production process The cladding pipe is made of two layers of metal pipes inside and outside, with a layer of insulating layer in the middle, which can be used to transport pipes with different media such as high temperature, low temperature, high pressure and low pressure. The corrugated pipe is formed by forming and welding metal sheet, which has the characteristics of light weight and good elasticity, and is mainly used in the fields of automobiles and airplanes. Different 2. uses Coated pipes are often used to transport high-temperature media, such as infusion pipes in petroleum, chemical, aviation and other industries; while corrugated pipes are gradually popular for their low cost and convenient installation and are used in some household appliances, vehicle exhaust pipes, and automobiles. Engine cooling system, etc. Differences in 3. structure The structure of the cladding pipe is relatively complex, consisting of two metal layers and an insulating layer inside and outside, which can play the role of isolation, heat preservation, and corrosion protection. The corrugated pipe is in the form of a corrugated pipe wall, which reduces the ratio of the inner diameter of the pipe to the outer diameter of the pipe, so it can effectively reduce the pressure loss. To sum up, although the coated pipe and the corrugated pipe are metal pipes, they are different in the production process, use and structure. The specific choice of pipe needs to be judged according to actual needs.

How many years is the life of the plastic pipe used in the gas pipeline

The life of plastic pipes depends on many factors, such as type, thickness, installation, etc., and can generally be used for 20-50 years. Advantages and disadvantages of using plastic pipes The use of plastic pipes in domestic gas pipelines is becoming more and more popular, because compared to traditional metal pipes, plastic pipes have the following advantages: 1. Lightweight and easy to install: Plastic pipes are lighter and easier to install than metal pipes. Moreover, the length of the plastic pipe can be customized, which reduces the connection and avoids the risk of pipe damage. 2. Corrosion resistance: Metal pipes are easy to rust, causing blockage and leakage, while plastic pipes have good corrosion resistance and strong acid and alkali resistance. 3. Energy saving and environmental protection: The thermal conductivity of the plastic pipe is lower than that of the metal pipe, which avoids the loss of part of the energy. Plastic pipes can also be recycled, reducing environmental pollution. However, the use of plastic pipes also has its disadvantages, such as being susceptible to temperature changes leading to deformation, easy to be pierced and damaged.

How to choose a gas pipe? Compare the difference between a 6-point gas pipe and a 4-point gas pipe

The gas pipe is a key component connecting the gas stove and the gas line. Choosing the right gas pipe is very important for the safety and use of the gas stove. When choosing a gas pipe, there are 6 points of gas pipe and 4 points of gas pipe. What are the differences between them? 1. the difference between 6 points gas pipe and 4 points gas pipe The main difference between the 6-point gas pipe and the 4-point gas pipe is the pipe diameter. The pipe diameter of the 6-minute gas pipe is DN20, while the pipe diameter of the 4-minute gas pipe is DN15. Due to the different pipe diameters, the gas delivered by the two is different, which in turn affects the size of the firepower. Generally speaking, the firepower of the 6-point gas pipe is larger than that of the 4-point gas pipe, which is more suitable for restaurants, restaurants and other areas, and the gas volume of the 4-point gas pipe is enough to meet the needs of ordinary families. However, because the gas volume of the 6-point gas pipe is larger, the gas cost is more than that of the 4-point gas pipe. If gas is needed for heating, a larger 6-point gas pipe is also needed. Precautions for 2. use of gas pipe 1. Regularly check and replace the gas pipe. Due to the long-term use of the gas pipe, problems such as aging, falling off, and wear may occur, so regular inspection and replacement are required. Especially at the joint, due to the higher temperature and more stored items, gas leakage accidents are more likely to occur. If the gas pipe is found to be aging or damaged, it should be replaced with a new gas pipe in time to ensure safety. 2. Use pipe buckle to avoid falling off. When using the gas pipe, it is necessary to use the pipe buckle to avoid the gas pipe falling off. In addition, the gas pipe should not be too close to the stove to avoid being damaged by high temperature. When the gas is not used, the gas valve must be closed in time, and the kitchen must be kept ventilated to avoid gas leakage and poisoning accidents. 3) Be vigilant. When using the gas pipe, always be vigilant. If you smell the gas odor, close the gas pipe in time and find the leak point. Can not take measures without authorization, should find professionals to replace the gas pipe in a timely manner. conclusion] The gas pipe is an indispensable part in the use of the gas stove. Choosing the right gas pipe can ensure the normal use and safety of the gas stove. When choosing a 4-point gas pipe and a 6-point gas pipe, it is necessary to consider factors such as household use demand, gas cost, and safety. When using the gas pipe, it is necessary to regularly check, install the pipe buckle, maintain ventilation and vigilance to avoid safety accidents.

The difference between 6-point gas pipe and 4-point gas pipe

The main difference between the 6-point gas pipe and the 4-point gas pipe is the pipe diameter, gas volume, firepower, and the use of the occasion and cost. Specifically: 12 The pipe diameter is different: the pipe diameter of the 4-point gas pipe is DN15, while the pipe diameter of the 6-point gas pipe is DN20. This means that the 6-point gas pipe can deliver more gas, thus providing more gas and firepower. Gas volume and firepower: Due to the difference in pipe diameter, the gas volume and firepower of the 4-point gas pipe are relatively small, which is usually sufficient to meet the needs of ordinary families. The 6-point gas pipe has a larger gas volume and firepower, which is suitable for restaurants, restaurants and other occasions that require larger firepower, as well as the need for gas heating at home. The cost is different: due to the larger amount of gas delivered by the 6-point gas pipe, the gas cost to be paid when using the 6-point gas pipe will be higher than when using the 4-point gas pipe. In summary, the choice of which gas pipe depends on the specific needs and occasions. For the average family, the 4-point gas pipe is enough to use, and if it is a restaurant or a family that needs to use a lot of gas for heating, it is recommended to choose the 6-point gas pipe to obtain a larger gas volume and firepower. At the same time, considering gas safety and efficiency, it is also very important to regularly check the condition of the gas pipe and maintain a certain installation distance.

How to judge the quality of the gas pipe

The quality of the gas pipe can be judged by observing the appearance, listening to the sound, smell and so on. These methods are free. 1. Appearance Observing the appearance of the gas pipe can preliminarily judge the quality. A good gas pipe has a smooth surface, uniform color, and no obvious dents or flaws. The surface of a poor quality gas pipe will have obvious flaws or dents, or even cracks, which will reduce its durability and safety. In addition, the connection of the gas pipe also needs to be observed, whether the connection is regular and firm, which will also affect the safety of the gas pipe. 2. sound Tap the gas pipe with your hand and listen to its sound to judge its quality. Generally speaking, the sound of a good gas pipe knocking is crisp, such as the sound of a metal collision; while the sound of a poor quality gas pipe is monotonous and dull, and there is no echo. In addition, if you pinch the gas pipe with your hand, a good gas pipe will be elastic, while a poor quality gas pipe will lose its elasticity. 3. taste If the quality of the gas pipe is poor, it may emit some unpleasant odors. When buying a gas pipe, you can smell it. 4. Other In addition to the above three methods, you can also start from the brand, manufacturer, after-sales service, etc., to understand the specific situation of the gas pipe, and to purchase guaranteed products.
