When we talk about an eco-city, we are essentially talking about a city that "can breathe and heal itself" - it can not only withstand the test of heavy rain, but also minimize the load on the environment in daily operation. And the "invisible support" of all this is hidden in the underground criss-crossing drainage pipe network. As the "blood" of the city, the toughness of the pipe network directly determines the "anti-strike ability" of the eco-city, but the pain points of traditional pipes that are easy to settle, slow drainage, and unenvironmentally friendly have become the "blocking point" for the advancement of urban ecology. The emergence of AD pipe HDPE carat pipe is breaking the "inner project" of the eco-city with the "toughness" of the product.

In urban construction, the underground environment is never a "smooth road": soft soil foundation, vehicle load, pipeline staggered... These factors are all testing the "compressive ability" of the pipe. The AD HDPE carat pipe adopts a unique "steel belt reinforced spiral corrugated pipe" structure, and the ring stiffness can reach SN8 and above (equivalent to the pressure of 8000 cattle per square meter). Even if it is buried in complex areas such as main roads and subway lines, it can effectively resist soil settlement and ground load, and avoid the "rupture leakage" and "pavement collapse" problems common to traditional concrete pipes. In the municipal drainage project of a new urban area in Hangzhou, the pipe was applied to the soft soil foundation section. It has been put into use for 3 years without any structural deformation, becoming a benchmark case of the local "toughness pipe network".

Drainage efficiency is the "core indicator" for ecological cities to deal with rainstorm waterlogging. The inner wall of the HDPE carat pipe is made of flat PE material, the roughness is only 0.01mm (the traditional concrete pipe is about 0.1-0 mm), the water flow resistance is more than 40% smaller than that of the traditional pipe, and the drainage enhancement capacity under the same pipe diameter is 30%. During the renovation of an old community in Shenzhen, residents frequently complained because of the "water on the first floor overflowing the threshold" during the rainy season. After replacing it with the AD carat pipe, the drainage speed of the pipe network was shortened from the original 2 hours to 40 minutes, completely solving the waterlogging problem that has plagued the community for 10 years. "Now it rains, there is no need to move sandbags to block the door, and children can play downstairs with confidence." The words of the resident Aunt Wang became the most real praise.

The "ecology" of an eco-city is not only the visible green trees and safflower, but also the invisible "low-carbon cycle". AD HDPE carat pipes are made of food-grade high-density polyethylene as raw materials. There is no heavy metal precipitation in the production process. After being discarded, they can be recycled and reused 100%. Compared with traditional concrete pipes, production energy consumption is reduced by 20% and carbon emissions are reduced by 15%. In the construction of a "zero carbon park" in an industrial park in Suzhou, the pipe was incorporated into the drainage system to help the park achieve "the minimization of the carbon footprint in the whole life cycle of the pipe network", which became an important plus for the park to declare as a "national-level ecological demonstration park".

For an eco-city, "less maintenance" is "more ecology" - frequent excavation and maintenance not only wastes resources, but also destroys the urban ecological texture. The designed service life of AD HDPE carat pipe can reach more than 50 years (2-3 times that of traditional concrete pipe), and it is resistant to acid and alkali, corrosion, and can operate stably even in corrosive environments such as chemical parks. In a chemical park in Ningbo, AD carat pipe has been used continuously for 12 years without major maintenance during this period. Compared with traditional pipes, the annual maintenance cost saved is equivalent to 15% of the initial investment, truly realizing "one investment, long-term benefits".

The construction of an eco-city has never been a "face project", but a "inner work". AD Pipeline uses HDPE carat pipes as a carrier to integrate "toughness", "environmental protection" and "efficiency" into every inch of the underground pipe network: it is like the "ribs of the city", supporting the high-rise buildings and people on the ground; like the "lungs of the city", swallowing rainwater and sewage; more like the "genes of the city", writing "sustainability" into the operation logic of the city. When we walk on the boulevard of the ecological city, see the road without stagnant water after rain, and hear the murmur of water in the sewer, it is the AD carat pipe that "silently speaks" - it does not say "grand slogans", but only does "real support", using the quality of every inch of pipe to protect every toughness of the ecological city.

This is the most literal annotation of the "eco-city" by AD Pipeline: not to make the city "look ecological", but to make the city "run ecological" - starting from the underground pipe network, let every drop of water flow smoothly, let every inch of soil remain intact, and let every development leave no regrets. When the rainstorm hits, it is "the guarantee of peace of mind"; when the years pass, it is "the constant promise" - this is the "pipe" of HDPE carat pipe, and it is also the longest guardian of the eco-city by AD Pipeline.
