PE PA and PP corrugated hose look the same but quite different from each other
Industrial hoses are indispensable parts in modern industrial production. Therefore, the quality of industrial hoses is directly related to the smooth progress of the entire industrial production process, as well as the production efficiency and product quality.
The industrial hose serves in manufacturing, petrochemicals, food and medicine, automobiles and aviation. It has become an important link between various mechanical equipment and fluid media. Therefore, in-depth exploration of the importance of industrial hose quality will help improve the safety and reliability of industrial production. But also be the key to promoting high-quality development of the manufacturing industry.
The importance of industrial hose quality is very large. Here are some important reasons:
Safety
Industrial hoses serve in many industries to transport gases, liquids or chemicals. If the quality does not meet the standards, leakage, fire, explosion or other dangerous situations may occur. Then cause serious losses to personnel and property. For example, in the petrochemical industry, inferior industrial hoses may cause chemical leaks, causing great harm to the environment and staff. Therefore, high-quality industrial hoses must be able to withstand extreme conditions such as high pressure, high temperature and chemical corrosion. Because only in this way can ensure the safety of the working environment.
Reliability
In many industrial production processes, industrial hoses are responsible for conveying not only materials. But also fluid media that may have a direct impact on product quality. If the hose material is not good, the inner wall is rough or has impurities, it will cause contamination to the fluid medium. And then affect the quality of the final product. Especially in industries with extremely high hygiene requirements such as food and medicine, the material and cleanliness of industrial hoses are directly related to the safety of the products. Therefore, the durability and reliability of high-quality hoses are very important to keep the production line running normally.
Durability
Industrial hoses are often subjected to forces and pressures such as pulling, bending and squeezing during use. If the quality of the hose is not up to standard, it is prone to problems such as cracks, aging and wear, and failures and damage. This requires frequent replacement and repair. But this will undoubtedly increase production costs and reduce production efficiency. Therefore, a good hose should have the characteristics of wear resistance, aging resistance and strong durability. At the same time, it can withstand long-term use and repeated use.
Performance stability
Industrial hoses are used in different working environments and process requirements, and their performance stability is required to be very high. For example, under high or low temperature conditions, the hose should maintain its shape and elasticity. Under contact with chemicals, the hose should be corrosion-resistant. Under high-pressure environments, the hose should be resistant to explosion. The instability of hose performance stability will lead to the hose not being used correctly and causing many problems.
In summary, the importance of industrial hose quality lies in ensuring the safety of the working environment, the stability of the production line and the quality of the product. Choosing high-quality industrial hoses can reduce the risk of equipment failure and production downtime, and improve work efficiency and economic benefits.
A low quality industrial hose will cause serious problem
Here I take the gas hose as example. Rubber gas hose is the most common hose in our daily life. Because we use it everyday. However, the gas hose must be a good quality one. Because once you get a bad one, there will be serious problem.
Not in compliance with regulations
According to the new national standard of the “Gas Engineering Project Specifications”: The scrapping period for gas stoves and gas water heaters is 8 years, and the service life of gas pipes cannot be lower than the scrapping period of gas appliances. However, the service life of rubber hoses is only 2 years, which does not meet the requirements of regulations.
But for families using rubber hoses, generally speaking, they will not change the pipes unless they are broken or leaking, and they will continue to use them, so there are great safety hazards.
Easy to age and leak
The materials of rubber and rubber-plastic hoses are not resistant to aging. If they are used for a little longer, they will naturally oxidize, then become hard, brittle, and crack, causing gas leakage.
Once they encounter open flames or electric sparks, they will cause explosions or fires, causing personal and property losses.
Real case
A residential building in Hangzhou, Zhejiang Province caught fire and exploded. The emergency repair personnel found that the rubber tube connecting the stove had a hole, which was suspected to be bitten by a rat. It was initially determined that the damage to the rubber tube was the main cause of the gas leak.
Easy to break
Due to the material, rubber and rubber-plastic hoses are not very strong in quality. If you don’t pay attention, you will be scratched or punctured by objects, causing gas leakage.
Real case
In a resident’s home in Xinhua Community, Chaoyang District, Changchun City, the rubber hose connected to the gas stove was damaged by external force. Then this results in gas leakage and flash explosion, causing 3 deaths and 3 injuries.
Fixed with clamps at both ends
Unreliable Both ends of the rubber hoses are fixed to the gas stove and gas meter with clamps and screws. This connection method looks very firm. But in fact it is not reliable at all and has poor firmness.
This connection method has poor sealing. And it is easy for the gas pipe to loosen or fall off. This will naturally cause gas leakage. Moreover, the clamps and screws will rust or loosen over time, affecting the stability of the gas pipe.
Real case
A resident in Liaoning Province caused a gas leak in his home due to the fall of the gas hose, which caused an explosion. The accident caused the unfortunate death of a 65-year-old man and serious injuries to his neighbors.
Not resistant to high temperature and corrosion
The temperature resistance and corrosion resistance of rubber and rubber-plastic hoses are very poor. This is why the pipe mouth connecting the stove position is very easy to age. If the gas pipe is directly exposed to the outside, it will accelerate the aging and damage of the gas pipe when it encounters high temp water and oil, and increase the risk of gas leakage.
Then how to improve the safety performance of rubber hose?
As a common pipe material, rubber hose is widely used in industrial and agricultural production and life. The quality of rubber hose directly affects the use effect and safety. Therefore, it is very important to select raw materials, produce and control the quality of rubber hose. The following will analyze the quality assurance of rubber hose from the aspects of raw materials, production process and quality control.
First of all, the selection of raw materials for rubber hose is very important
Rubber hose is mainly composed of rubber and reinforcing materials. The quality of rubber directly determines the elasticity, high temperature resistance and corrosion resistance of the pipe. Therefore, we should choose high-quality rubber raw materials to ensure that it has good physical properties. At the same time, the addition and ratio of reinforcing materials also need to be strictly controlled to ensure the strength and wear resistance of rubber hose.
Secondly, the production process has a huge impact on the quality of rubber hose
Mixing, extrusion, vulcanization and other processes are required in the production process. Each link may affect the quality of rubber hose. For example, the rubber temperature, time and speed need to be controlled during the mixing process to ensure that the rubber and reinforcing materials are fully mixed. During the extrusion process, the size and shape of the extrusion port need to be controlled to ensure that the appearance and size of the pipe meet the requirements. During the vulcanization process, the vulcanization temperature and time need to be controlled to ensure the strength and aging resistance of the rubber tube.
Finally, quality control is an important link to ensure the quality of rubber tubes
Manufacturers should establish a strict quality management system, strictly inspect and control the raw materials, and ensure that every link in the production process meets the standard requirements. At the same time, the finished products are sampled and tested comprehensively to ensure the stable and reliable quality of the rubber tube.
In summary, the quality assurance of rubber tubes needs to be comprehensively considered from the aspects of raw material selection, production process and quality control. By strictly controlling the quality of raw materials, optimizing the production process and establishing a sound quality management system, it can be ensured that the rubber tube has good performance and reliable quality. Thereby improving its application effect and safety in industrial and agricultural production and life.
