Proper installation of stainless steel corrugated pipes is crucial to ensure their optimal performance. The following are the key steps and precautions for installing stainless steel corrugated pipes:
1. Inspection of bellows: Firstly, check whether the category and size of the bellows meet the requirements, ensuring that the selected bellows match the project requirements.
2. Prepare tools and materials: Prepare the necessary tools and materials such as wrenches, cutting machines, connectors, sealing rings, and gaskets.
3. Cutting corrugated pipe: Mark the cutting position according to actual needs, and use a cutting machine to cut the corrugated pipe along the marked area. Ensure that the cutting surface is flat and free of burrs.
4. Processing the cut surface: Place the cut corrugated pipe into the slot, exposing 3 sections of the corrugated pipe. Gently impact the corrugated pipe in the slot with a hammer to make it smooth.
5. Install pipe clamps: Install pipe clamps on the smooth part of the corrugated pipe to ensure that the pipe clamps are firmly installed and will not loosen.
6. Connecting pipes: Use specialized connectors to connect corrugated pipes to other pipes. During the connection process, ensure good sealing between the connector and the corrugated pipe to prevent water or air leakage.
7. Tighten the connectors: Use the correct tools and gradually and evenly tighten the connectors according to the torque requirements provided by the manufacturer. Avoid excessive force to prevent damage to the bellows or connectors.
8. Check installation quality: After installation, check whether the installation position and direction of the corrugated pipe are correct, whether the connection is firm, and whether the seal is good. Ensure that the corrugated pipe is not twisted or stretched.
9. Performance testing: Before actual use, pressure test the corrugated pipe to ensure that it can withstand the expected working pressure without any leakage.
In addition, the following points should be noted:
During installation, avoid scratching or colliding the corrugated pipe with sharp objects to prevent damage to its surface or structure. Ensure that the corrugated pipe is kept clean during installation to prevent impurities or dirt from entering the interior of the pipeline. Select appropriate corrugated pipe materials and specifications based on the usage environment and requirements to ensure that they meet the usage requirements.
By following the above steps and precautions, stainless steel corrugated pipes can be installed correctly to ensure their optimal performance and service life.

The manufacturing process of stainless steel corrugated pipes is special. On the basis of the original high-quality performance of stainless steel materials, the corrugated shape makes the pipe body have stronger compressive strength and better flexibility. It can bend 360 degrees and be shaped into any form without damage. Stainless steel corrugated pipes have a wide range of applications, even our household water supply pipelines can use stainless steel corrugated pipes.
The key lies in the strong performance of stainless steel corrugated pipes, which have high strength and pressure resistance, high and low temperature resistance, rust and corrosion resistance, and explosion resistance. In short, they are very durable. Durability is a priority factor for the public, and we do not want the maintenance caused by pipeline problems to affect our lives and cause certain economic losses. For example, rubber gas hoses have long been our first choice for gas pipes used in gas appliances. But after using it, I didn't pay too much attention anymore. I used it for many years until it was damaged and leaked, and then I realized that this gas pipe was not good.Nowadays, more and more people use pipeline gas, but the majority still use rubber hoses. Apart from cost saving considerations, they are not aware of the existence of stainless steel corrugated pipes as gas pipes. Narrowly listening, do you still think that this hard metal tube can be used as a gas pipe? Rubber hoses are soft and flexible, making them easy to use.Little did they know, stainless steel corrugated pipes also become very soft after being processed into corrugated shapes, with denser ripples becoming softer. The key is that it can be used in many ways, even longer than rubber hoses, and will not age or cause metal corrosion. The outer layer is wrapped in flame-retardant and fire-resistant materials, which not only improves its appearance but also resists high temperatures, providing an additional layer of protection for safety.The stainless steel corrugated hose for gas also adopts a more secure threaded connection on the interface, and the all metal hose will not age and loosen like rubber hoses. Moreover, the corrugated hose is flexible and can be bent and shaped, without causing dragging at the interface. Although the rubber hose is soft, it always forms dragging at the interface, which will crack and leak air after aging. Compared to stainless steel corrugated hoses, it is obviously safer.At present, after years of use, the superior performance of stainless steel corrugated hoses has been verified and widely recognized by users. As the preferred pipeline gas installation pipe material for gas companies, stainless steel corrugated hoses have unparalleled safety performance in pipeline gas compared to other pipe materials.

VIEW DETAILSNowadays, the water pipes used in home decoration are generally made of plastic, including PVC, PE, and PPR. The choice of material mainly depends on what goes inside, as well as the temperature of the material. The reason for this is that the melting temperature of plastic is generally within the range of 200-300 degrees Celsius. After the temperature is high, the physical and chemical properties of the water pipes will change, such as strength. Another issue that is easily overlooked is the expansion amount, which tests not only the pipe but also the joints of the pipe, such as connecting tees and elbows. This cold and hot change can cause the rubber parts under the threaded joint to become loose. If the installer doesn't pay attention, then just wait to knock on the tiles and remove the floor. Of course, There is also a hot melt method for joints, which mainly involves the connection between pipes and the connection of small bends. The hot melt area may not look much on the outside, but if you cut it open, you can clearly see irregular replacement protrusions inside, which feel a bit like intestinal obstruction. These ring protrusions will affect the size of the water flow, but the impact is not significant. The problem is that most households use tap water, and when not in use, scale, that is, calcium and magnesium salts in the water, will deposit, just like the skin poured out of the old water bottle liner permanently. This thing likes to accumulate in the hot melt area. In some northern regions, if the water hardness is particularly high, this problem will occur. It is indeed quite easy to cause pipe blockage, and the most obvious manifestation is that the water flow is small and the water pressure decreases.However, the biggest advantage of rubber tubing is its affordability! Please remember this sentence, this is the biggest advantage.Next, pull the stainless steel corrugated pipe again.....Firstly, based on my experience, the main materials for stainless steel corrugated pipes on the market are 304 and 316L, which are also common steel in the 300 series in China. The difference in chemical composition between the two is basically whether Mo (molybdenum) is added or not, which mainly affects their corrosion resistance. However, to be honest, the residual chlorine in the tap water you use in this pipe can be directly consumed by people. Therefore, whether or not to use a high-grade material like 316L is subjective. If you want it to be permanent, you can add 316L and think it's okay. It's okay to use 304. Trust me, austenite is not as fragile as you think. All the stainless steel corrugated pipes you can see or buy on the market now, without exception, are welded pipes. To put it bluntly, they are welded by rolling iron sheets together. The welding methods here are divided into spiral welds and straight welds. Generally speaking, straight welds are better than spiral welds. Don't ask why, if you want to ask, you can check the literature yourself. After the iron sheet is welded, it is a very long and straight pipe with a smooth surface like washing. Next, we need to add ripples to this pipe.
This wave is mainly aimed at increasing the deformation capacity of the entire pipe, similar to a spring. After the wave is applied, it can be bent to solve the problem of requiring bends in the connecting parts. It can reduce the use of pipe fittings and bends, thereby reducing the cost of the entire pipeline system. The commonly seen one on the market now is the ring wave, which is like putting multiple rings on a pipe. The benefits of corrugated pipes are also very obvious. Firstly, they have high structural strength, which is not on the same level as plastic pipes. Secondly, the inner wall is smooth, and the metal is naturally hydrophobic and has a fast flow rate. Thirdly, they are carbon free, so there is no need to consider microbial reproduction like plastic pipes do now.It seems that stainless steel corrugated pipes are indeed good, but this type of pipe has a fatal problem, which is that it is expensive! It's just expensive! It's just expensive! Generally, pipelines are measured based on 100 square meters, usually around 40-50 meters. Without considering underfloor heating, the entire water supply costs only two to three thousand yuan. However, if you want to replace it with stainless steel pipes, the cost will at least double. After all, the thicker the stainless steel pipe, the more expensive it is. By the way, the common thickness on the market is 0.3. If you ask why it is 0.3, it is sufficient for one day and cannot be made even thicker. But now I do know that there is a company that can achieve 0.8 thickness, which is not at all the same level as 0.3.After installation, everyone needs to maintain pressure. Stainless steel pipes outperform plastic pipes in this regard. Plastic pipes maintain a pressure of 5-6 kilograms, while stainless steel pipes start at 25 kilograms. I have seen the most exaggerated test of maintaining a pressure of 60 kilograms. However, the pressure of tap water at home is usually 2-3 kilograms, so water pressure is not a problem. But after maintaining pressure on stainless steel pipes, if the two ends are clamped tightly, the middle ripple will be stretched. Sometimes the pressure will bounce back when released, and sometimes it will not. This depends on whether the deformation has exceeded its yield limit. Otherwise, it would be like a straightened spring swaying and hanging there, and the owner would not pass the visual inspection when they come over. Therefore, some small manufacturers' stainless steel corrugated pipes still need to be carefully inspected. If it were me, my choice would be stainless steel corrugated pipes. Once and for all, relieve future troubles!
With the development of the times, people's acceptance of information is becoming more and more widespread. However, in today's world of such a huge amount of information, the relevant knowledge of gas pipes is increasingly being ignored. We should re-examine gas pipes for safety and family responsibility. So, let's reply to the question that many people have been questioning recently, which is better between gas stainless steel corrugated pipes and gas pipe hoses?There are two types of gas pipes, one is stainless steel corrugated gas pipe, and the other is gas pipe hose (metal wrapped hose); Each has its own advantages and disadvantages. It is recommended to choose according to one's own situation. The following is an introduction to the advantages and disadvantages of two types of hoses:1、 The material of stainless steel bellows (also known as stainless steel bellows) is 304 or 316 stainless steel, which can be selected according to different requirements. 316 is used in industries with relatively high requirements. For the gas pipeline industry, there is no special requirement. The 304 specification can already meet the requirements. Stainless steel bellows have the advantages of aging resistance, high temperature resistance, rat bite resistance, anti falling off, corrosion resistance, and long service life. However, the price is higher than that of gas hose (metal wrapped hose), and when using stainless steel corrugated hose, it is important to be careful not to disturb it back and forth, which may cause metal fatigue or leakage of threaded joints. On the other hand, stainless steel corrugated pipes should not be too long. If they exceed 1.5m, they need to be fixed; When mechanical damage occurs due to external force, we cannot visually determine whether there are cracks or stress concentration, and it must be replaced.2、 Gas hose (metal wrapped hose) is generally divided into three layers, with the innermost layer being a PVC rubber inner tube, the middle being a metal protective layer, and the outermost layer being a flame retardant layer. The metal protective layer plays a role in clamping the PVC inner pipe, and the protective layer plays a role in flame retardancy, preventing rodent bites and scratches. The price of PVC gas hose ends is relatively cheap. Suitable for household use where liquefied gas is connected to a liquefied gas tank and requires regular ventilation. Compared to the first type of stainless steel corrugated pipe, it is more convenient to replace.From the above two types of non material hoses, stainless steel bellows and gas hose, each has its own advantages, depending on where you are using them. The conclusion is already clear that stainless steel bellows and gas hose are on par. However, the safety of household gas is not only a matter of gas pipes, but also depends on individuals' good habits of using gas pipes. In addition to inviting professionals to come and inspect, we also need to regularly self check gas appliances in daily life: first, smell the odor. There is a special odor added to the gas, which is easily detected in case of leakage; Secondly, without using gas at all, check if the number in the red box at the end of the gas meter is moving; Finally, spray soapy water on each interface. If bubbles are found, it indicates a leak. Gas enters every household, safety depends on everyone!
