Pipelines are connected by Pipelines, Pipeline couplings and valves to transport gas, liquid or fluid devices with solid particles. In fact, this kind of device has been used in ancient China thousands of years ago. The evolution of human water supply Pipelinelines for thousands of years is also the evolutionary history of human civilization.

 

 

 

 

 

Clay Pipeline

 

 

 

According to worldwide archaeological excavations, the earthen drainage Pipeline unearthed from the ancient city site of Pingliangtai in Huaiyang County, Henan Province (approximately 4600 years ago, 600 years earlier than the Xia Dynasty) is the oldest drainage Pipeline. The real drainage Pipelines in the West did not appear until the Industrial Revolution, more than 4000 years later than China.

 

 

 

Archaeologists discovered three ceramic drainage Pipelines totaling more than 5 meters in length. These drainage Pipelines consist of a single ceramic drainage sleeve. The drainage sleeve is large at one end and small at the other end. The small end is inserted into the larger side, and the Pipelines are set one by one to form a long drainage Pipeline to drain water outside the city.

Water is the source of life and the lifeblood of a city. The main measures of water supply in ancient Chinese cities were digging wells to draw water, opening canals, building dams to store water, and water carts to deliver water to meet people's living and production water needs.

As early as 2000 AD

 

Bamboo has been widely used in China as the main water Pipelineline material

 

 

 

 

Lead Pipeline

 

 

 

During the rule of ancient Rome, more than ten aqueducts were constructed, and the water from the canals was filtered and conveyed through lead Pipelines wound with lead sheets.

Some scholars revealed that lead poisoning may be one of the reasons for the decline of ancient Rome

 

 

 

 

Galvanized steel

 

 

 

In the middle of the 20th century, galvanized Pipelines were the mainstay, and various metal Pipelines coexisted.

Copper and iron Pipelines

 

 

 

With the rapid development of the national economy and the improvement of metal machining technology, copper Pipelines and iron Pipelines have appeared one after another, replacing lead Pipelines.

 

 

 

Copper Pipelines are durable and environmentally friendly, but with high cost and high construction requirements, they will produce patina after a long time.

 

 

 

 

PP-R plastic Pipeline

 

 

 

With the rapid development of petrochemical and plastic industries, plastic Pipelines such as PPR and PE are booming. Under suitable conditions, PPR's pressure resistance, corrosion resistance, high and low temperature resistance can meet the daily needs of consumers; the connection method adopts the hot melt method of the body material, which can greatly prevent water leakage at the interface;

 

 

 

 

 

The main disadvantages of PP-R plastic Pipeline

 

Under critical use conditions, the pressure resistance, high and low temperature resistance of PPR will quickly deteriorate. For example, a low temperature below 5°C will rapidly increase the brittleness of PPR, making it difficult to install. Especially in the winter when the temperature is very low, the PPR Pipeline may burst easily.

 

 

 

The structure of PPR is not dense, it can transmit light and oxygen, so that bacteria and microorganisms will grow on the inner wall of the water Pipeline, which will affect the water quality;

 

 

 

PPR has no self-cleaning and antibacterial effects, and the water quality will quickly deteriorate after a period of non-use.

 

 

 

Each section of PPR is limited in length and cannot be bent for construction. The Pipeline laying distance is long or there are many corners, and a large number of joints are required. PPR Pipelines are cheap but the price of accessories is relatively high.

 

 

 

The PPR connection method adopts the hot melt method of the main body material, which is complicated in construction and requires high construction technology. Generally, water seepage is at the Pipeline connection.

 

 

 

 

 

 

Stainless steel Pipeline

 

 

 

Stainless steel is a recognized healthy material that can be implanted into the human body. Stainless steel Pipelines have been successfully used in developed countries for many years. In particular, thin-walled stainless steel Pipelines have gradually become a new material for home improvement water supply Pipelines due to their characteristics of safety, reliability, sanitation, environmental protection, and economical application.

 

 

 

The surface of the stainless steel material will form a dense chromium-rich oxide film, so that the stainless steel water Pipeline can adapt to various water quality, and has good performance in pressure resistance and corrosion resistance; toughness and pressure resistance are incomparable with PPR; safe and non-toxic It is non-corrosive and will not cause secondary pollution of water quality.

 

 

 

Unique advantages of stainless steel Pipelines

 

Safe and reliable

 

Tensile performance

The tensile performance is 8-10 times that of PP-R Pipeline

 

Low thermal conductivity

 

Thermal conductivity is one-fifth of copper

 

Sanitation and environmental protection

 

Strong corrosion resistance

 

The Pipeline is solid-solution treated to avoid water quality problems caused by corrosive substances

 

High hygienic performance

 

Stainless steel is a healthy material that can be implanted in the human body

 

Affordable

 

High efficiency

 

The service life of stainless steel Pipelines can be as long as 100 years

 

Easy to install and maintain

 

Stainless steel Pipelines are easy to operate and safe, and construction is quick

 

 

 

Go back to history and follow the trend. The home improvement Pipelines around us have gone through from galvanized iron Pipelines, PVC-U water supply Pipelines, aluminum-plastic composite Pipelines, to PPR plastic water Pipelines, copper water Pipelines, and then to stainless steel water Pipelines. This is a process of continuous updating. For the water and electricity installation stage of the top "hidden project" for home decoration, the lack of reliable Pipeline guarantee will bury potential safety hazards. Stainless steel green Pipeline is a healthy choice in the new era.
