First of all, look at the specifications and classification of rubber joints.
1. According to the performance, it can be divided into general, special and heat-resistant.
General grade: it is suitable for conveying water with temperature of-15℃ ~ 80℃ and acid solution or alkali solution with concentration below 10%.
Special category: suitable for special performance requirements, such as oil resistance, blocking resistance, ozone resistance, wear resistance or chemical corrosion resistance.
Heat resistance: suitable for conveying water with temperature higher than 80℃
2. According to the structural form, it is divided into single sphere, double sphere, three sphere, elbow sphere and wind pressure coil body.
3. According to the shape, it can be divided into concentric diameter, concentric diameter and eccentric diameter.
4. According to the connection form between the product and the pipeline, it can be divided into flange connection, threaded connection and clamp connection, threaded pipe flange connection, etc.
5. According to the working pressure: 0.25MPa, 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa and 6.4MPa.
Regarding brand recommendation, let's first look at a scenario simulation:
"Is it reliable to buy cheap rubber joints?" "Excuse me, heroes who have bought rubber joints, which industries use high-performance rubber joints with high price and good quality. Can you sell them? I think owners generally don't care too much about this small part, as long as they can guarantee that there will be no accidents for one year, the quality will be cheaper and they can buy it with more kickbacks. Right? Is there any industry or unit that requires the use of rubber joints with high quality, high performance and high price? "
It can be seen that the person who asked this question must be interested in contacting the agent of rubber joint industry, and some problems can be seen from his question. Although he is also concerned about the price of rubber joints in places like property, he wants to buy rubber joints not because of the good quality, but because he wants to get kickbacks, regardless of the consequences, because as long as the products can be used for a certain period of time before problems occur, then he can push the final problem to the quality of rubber joints and continue to get kickbacks in this way. If the rebate continues after the problem occurs, it means that the inferior rubber joint has no quality guarantee.
Then we analyze this problem from the material of rubber joint:
As the saying goes, when users choose rubber joints, they must choose materials according to the media used. When choosing a rubber joint, don't look at the price first, but at its use demand. For example, we need to apply this product to rubber joints with high acid and alkali corrosion, but you are only willing to pay the price of ordinary rubber joints, and problems will inevitably occur after installation. Let's not talk about the price of rubber joints. How much energy can you solve the trouble caused by the problem?
Finally, we analyze this problem from the perspective of brand quality:
In fact, rubber products are deep in water, and the quality of the whole industry is different. But if you don't buy a good rubber joint, it will be dangerous at any time and it is easy to have an accident. Can you find someone who sells things to you after the accident? This is whether you want to choose a guaranteed manufacturer or a knockoff machine without a brand.
Today's society is a society where economy tells development. With the progress of society and the increase of labor price, commodity prices will also rise appropriately. When you find that the price of the products you buy is the same as in previous years, and some of them are even lower, please think about whether they cut corners or lower the quality standard in this environment of increasing production costs in all aspects.
As a product, rubber joint plays an important role and belongs to the key link, although it is not widely used in the vast engineering. Only products with the word "quality" can stand up. Because rubber products are not vulnerable parts like steel, if you muddle through and choose poor quality products, the owners will eventually doubt the supply of all suppliers. And cause greater invisible losses.
Therefore, the choice of rubber soft joint manufacturers should choose Songjiang's high-end brand. After all, it is used in engineering and quality is crucial. When choosing a regular and large manufacturer, don't just look at the price, so as to avoid various unsolvable problems in the future. Just looking at the price will definitely suffer, because many of them are leather bag companies with poor after-sales or no after-sales directly. Don't think that buying low-priced products takes a big advantage, but in fact you have suffered a big loss. It is very troublesome for some big projects to go wrong, so you must choose a real and reliable brand entity manufacturer, so that you can have no worries.
