At present, most of the gutter grates that use grooved pipe fittings in Taiwan are mainly made of cast iron, which is expensive, heavy, consumes a lot of cast iron, and is easy to lose. After exploratory investigations, Taiwan State Construction Engineering Research Institute and Hainchu Municipal Engineering Management Office carried out research on steel fiber reinforced concrete rainwater grate. The steel fiber reinforced concrete rainwater grate is made of steel fiber reinforced concrete as the base, with appropriate reinforcement, and the frame is reinforced with glass fiber reinforced plastic and steel ring. It is carefully processed and can be used with the original grate frame. This kind of grating takes advantage of the excellent crack resistance, impact resistance and fatigue resistance of steel fiber reinforced concrete of grooved pipe fittings and the characteristics of steel fiber reinforced concrete tending to two-dimensional distribution in thin-walled members, and has the advantages of low cost, light weight, and can save a lot of cast iron. Compared with the cast iron gutter, the grooved pipe fittings can reduce the weight of components by 30%, reduce the cost by about 50%, and meet the requirements of heavy vehicle loads.

At present, the grooved pipe fittings we use are generally made of cast iron, so many people who do not want to pay attention to this point, and the robbery of grooved pipe fittings is increasingly rampant. Then we must come up with a complete set of methods and strategies to prevent the recurrence of the stolen time of grooved pipe fittings. Domestic theft and damage to municipal public facilities occur frequently, especially the manhole cover of cast iron grooved pipe fittings is the most serious. According to the specific technical requirements of heavy traffic and vehicle load, other cities have carried out the research and development of steel fiber cement concrete inspection manhole covers for grooved pipe fittings. After comparative experiments and technical and economic comparisons, milled steel fibers are finally selected as fiber reinforcement materials for high-strength steel fiber concrete. It is reported that more than 10000 manhole covers made of steel fiber materials have been installed after the improvement project of the back streets and alleys in Hainchu in the past few years. Except for occasional damage, none of them have been stolen so far, because steel fibers have no recycling value. Thieves are not interested. Hainchu City plans to replace the manhole cover of cast iron grooved pipe fittings in the urban area within 3 years. By 2025, thieves will not think about the manhole cover in Hainchu.

In the past, we have talked about a lot of misdeeds about inferior grooved pipe fittings, how they can't work properly, how to identify them, and so on. And then do you know how a qualified grooved pipe fitting works under normal working conditions? Perhaps, if you understand and recognize the normal high-quality grooved pipe fittings, you will know the difference between high-quality and low-quality. 1. First of all, a qualified grooved pipe fitting is a national standard pipe fitting, which conforms to the standards established by the country. This is a general model, and the second is non-standard. 2. Secondly, the material composition of a qualified grooved pipe fitting is very rigorous and scientific, without flaws. It is made of pure cast iron material, which is very hard and has some softness at the same time. 3. Another very important point is that a high-quality grooved pipe fitting must be very strong in terms of voltage regulation and pressure, and its sealing performance is also very good.

After the installation of grooved pipe fittings, there is a misunderstanding, and we also ask our friends to pay attention, that is, many times, the maintenance and maintenance work after the installation of grooved pipe fittings is neglected. In people's daily life, grooved pipe fittings occupy a very important position, and while we are using it, it is very important to do a good job of its protection, so what are the specific protection work? 1. It is very important whether the grooved pipe fittings strictly meet the usage specifications in daily use, which has a great impact on its function and life, so it is very important to use it strictly in accordance with the specifications; 2. After use, in order to prevent displacement and offset, the reserved holes must be filled in time; 3. In order to ensure that the pipe fittings are not affected by other factors during use, the surrounding environment should be kept neat and clean, and remember to keep away from contaminated items; 4. In order not to damage the structure of the pipe fittings, the diameter of the reserved hole must be kept within the specified size; 5. Always check the pipe fittings to see if the parts are missing. If they intersect with other pipe fittings, remember not to disassemble them at will.

Grooved fittings are no longer the only tool for connecting pipes! Suddenly, the majority of friends or manufacturers who heard this news exploded the pot overnight. Is there a new connection method or other tool that can replace the grooved pipe fittings? What is it, or is there a mystery in it? Of course not. In fact, grooved pipe fittings still exist as a practical connection method. His status has not changed. What has changed is that he has added a twin brother, that is, plastic-lined grooved pipe fittings and valve grooves. Pipe fittings, why do these two ways and proliferating products appear? Because in the era of grooved pipe fittings, there are still many jobs that he cannot complete. At the same time, the market is constantly improving, and the connection of pipe fittings is also caused by the upgrade. When it comes to plastic-lined grooved pipe fittings, everyone is not unfamiliar with it, and it is not unfamiliar with valve-type grooved pipe fittings. The big family, in terms of vague concept, is a kind of grooved pipe fittings, which is a hard-to-separate relationship; grooved pipe fittings are no longer the only connection tool, because he has better helper, isn't it? Of course, with these two kinds of good helpers, when we use and work in the project, we will become more and more satisfactory hands, the work efficiency will be improved, and it will be more helpful for future pipelines. maintenance, which can be felt. If you have used the two good helpers of grooved pipe fittings, you can share your experience with us, we have generous gifts waiting for you.
