3. لوله های PPRضخامت دیوار

 

The wall thickness of the لوله های PPRمربوط به ظرفیت تحمل فشار واقعی لوله آب است. اگر چه ظرفیت تحمل فشار واقعی ازلوله PPR mainly depends on the mechanical properties of the PPR raw material, on the basis of the same material, the thicker the wall thickness of the water pipe, the higher the pressure bearing capacity. it is good. Generally, the larger the diameter of the pipeline, the greater the flow rate, so the required wall thickness also increases, which is the basic principle of pipeline design.

 

برای لوله های آب با قطر لوله یکسان ، اگر ضخامت دیواره متفاوت باشد ، سری لوله های S انتخاب شده توسط آنها با ضریب ایمنی طراحی متفاوت است. مسلماً چنین لوله های آب با ضخامت دیواره های مختلف در شرایط یکسان دارای عمر مفید متفاوتی هستند و طول عمر لوله های آب با دیواره ضخیم بیشتر خواهد بود.

4. لوله PPR fittings

 

کیفیتلوله PPR fittings, especially copper fittings with wire mouth, is still very large. As far as copper itself is concerned, there are nickel-plated brass and non-nickel-plated brass. The quality of non-nickel-plated brass is better.

 

Looking at the amount of copper, it is usually invisible from the outside of the pipe, but once the pipe is cut, the clue can be seen.

 

لوله PPR is a very simple product, and we don't have to think about it too complicated at all. Its quality is nothing more than the quality of the raw materials and the solid workmanship. Nowadays, there are many marketing gimmicks in the market, focusing on concepts and functions. Consumers often hear them in the cloud, and in the end they actually pay for things that don't have much actual value.
