Shi Ming Pipeline is an early enterprise in the plastic pipeline industry. I don't know when it was established. You can check official information. For the popularity of the three northeastern provinces, the channel of Shi Ming Pipeline developed earlier, and provincial offices were established very early. Although it is not as big as Jinde and Rifeng, and its influence and popularity are not as good as those of first-line brands, the product quality is still good. This established enterprise has accumulated his technical strength. In my impression, Shi Ming is also the drafter and participant of many national standards for pipeline industry. The details can be verified with the official, because of the time. I only know that Shi Ming is the drafting unit of many national standards. It is said that many big-name pipeline enterprises have cooperated with Shi Ming from the beginning. Regarding popularity, I think the development path of each enterprise is different. I don't know if it's appropriate. For example, Shi Ming is an honest farmer of cultivated land. Although other enterprises are farmers, they have all started to "fish ponds and farms". Shi Ming is simple, and other enterprises make public, each with its own merits. Simple, honest and diligent. In addition, the Shi Ming pipeline is quite powerful in engineering. More than 80% of the water separators of Evergrande Real Estate are made in Shi Ming, and all of them cooperate with large-scale real estate. How to put it? Every enterprise has its own emphasis. I believe that this enterprise has greater potential and space in market popularity than the first-line brands, and the same is true for agency distribution. The so-called "everyone knows, fans follow" (no source) means that if everyone knows, there is no secret, and if everyone doesn't know, it will attract people to follow!
