"System, please calculate, if the monthly supply of 10,000 tons of water, no pressurization equipment, ordinary water speed, 8 hours a day water pipe opening time, how big water pipe needs to be used?"

Wang Hao didn't want to do a lot of construction, if he used pressurized water pipes, such a long distance, once there was a little problem, it would be easy for the water pipes to burst, so he just wanted to build some ordinary water supply pipes.

As long as these pipes are strong enough, they will not break due to heavy pressure, nor will they be damaged within a few years due to natural corrosion.

Basically, as long as these two conditions are met, it can be manufactured.

The current text of the system: "Host, a water pipe with a diameter of 20 cm can meet this requirement." ”

“OK！”

Now that you know the diameter of the pipe, the next thing is to choose the material.

The materials of water pipes include galvanized iron pipes, PVC pipes, PPR pipes, aluminum-plastic composite pipes, stainless steel pipes, copper pipes, cement pipes, etc.

Galvanized iron pipes are the most commonly used water pipes in water companies.

The price of this kind of water pipe is low, but after a few years of use, a lot of rust will be produced in the pipe, and the yellow water flowing out will not only pollute the sanitary ware, but also be mixed with bacteria that breed on the uneven inner wall.

According to the test, this kind of corroded water pipe will cause high heavy metal content in the water, which seriously endangers human health.

Wang Hao directly discarded this material.

He clearly remembers that when he used to be at home, as long as the water company stopped the water, the water that had just been piped was usually rusty yellow, with an iron smell.

PVC pipe

Although the water pipe of this material will not rust, but the weathering is relatively fast, and it is easy to brittle off after a long time, and this kind of water pipe is generally used as a sewer pipe to discharge sewage, which is not resistant to water pressure or heavy pressure.

Frequent maintenance is a hassle when it is broken.

Abandon!

PPR pipe

This is an ordinary melt tube and is simple to install.

As a new type of water pipe material, it can be used as a cold pipe, a hot water pipe, or even a pure drinking water pipe.

Because of its non-toxic, light weight, pressure resistance and corrosion resistance, it is a commonly used water supply pipe at present.

But according to the news that Wang Hao learned through the grapevine

PPR pipes are not good!!

This kind of water pipe has no self-cleaning function and bactericidal function, and can easily become a gathering place for secondary pollutants in water quality and a breeding place for bacteria, which seriously threatens human health.

However, it is an undisclosed secret in the pipe industry that PPR plastic pipes are not suitable for household water pipes!

PPR raw materials are inexpensive, easy to install, and profitable.

If it is used for industrial water transportation or general purpose water transportation, it is very worthy of promotion.

The water that Wang Hao is now preparing to send to the natives is not only used for irrigation, but also for drinking, so he can only give it up.

Aluminum-plastic pipes are similar to PPR pipes, and they are also discarded.

Stainless steel pipes are too troublesome to install, and ordinary stainless steel will also have heavy metal pollution, and furthermore, there is not much iron in Wang Hao's system space, so it is discarded.

Copper pipes are a good choice, but the little copper that Wang Hao dug out has long been gone, and when does he plan to buy another batch from outside, although copper pipes have many benefits, he can only give up.

Cement pipes, too easy to get dirty.

Moreover, this material is too heavy, easy to produce, and the installation is only afraid that a crane will be used to install.

"It is a stress-resistant, durable, non-polluting, lightweight, ready-made material, which is really a test of my creative ability!"

Wang Hao quickly mobilized his brain and quickly thought of a solution.

Production of composite materials!!

"System, make a 20 cm diameter water pipe, the inner wall of the pipe is made of graphene plastic, the outer wall is made of PPB material (PPB is better than PPR), and the wall thickness is 1 cm!"

Wang Hao quickly set up various manufacturing data in the manufacturing panel.

System: "Available, please confirm the quantity manufactured!"

"Make 1 meter first!"

The system prompts: "Manufacturing, manufacturing completed, congratulations to the host for successfully manufacturing the new material, please name the new material!"

The system prompts again: "Because the host has created successful materials independently, the host experience point is 2, and the current host experience value is 180/200, please continue to work hard!"

Wang Hao was stunned for a moment, and jumped up happily.

"Oh oh! Bunker is up this way to get XP too!!"

With these two experience points, plus completing the task of systematically gaining the favor of the natives, you can immediately reach level 5!!

Level 5 has 9 times more space than level 4!!

"Host, please name the new material within five minutes! If the naming is not successful within five minutes, the system will adopt the default name!"

At this time, the system prompted again, and the virtual picture of the manufacturing drawings flashed in front of Wang Hao's eyes.

"Hehe! I'm sorry, I'm so happy for a while, I'll name it now, but let me see if the water pipe I made is good to use before naming it!" Wang Hao patted his head and said with a smile.

The 22-centimeter-thick white water pipe has been automatically put into Shangshen's warehouse.

Wang Hao clicked on the water pipe, and as soon as his mind moved, he moved the water pipe outside.

Next, Wang Hao first stood on the top of the water pipe, stepped on it hard, felt the weight resistance of the water pipe, and found that it was exactly the same as he thought, very solid, and the water pipe also has a very strong elasticity, which makes the water pipe not easily broken or damaged even if gravity suddenly applies to the water pipe.

Look at the inner wall of the water pipe.

The inner wall is made of a very thin, transparent graphene material.

Wang Hao took out a bottle of fruit juice drink and poured some into the tube, and the juice flowed along the inner wall without sticking to the wall of the tube.

"Not bad!!

"System, name the new material Water Guard material!!"

After a little thought, Wang Hao came up with such a Chinese material name.

"Whatever, let foreigners have a headache when translating the name of this material in the future!"

System: "The name has been successful, and the manufacturing drawings of the Water Guard material have been successfully saved!"

Wang Hao went upstairs first, found Li Qian, who was learning from each other with Xinghe, said a word to Li Qian, and walked towards the outside of the wall.

Wu Guang, the head of the machine security detachment, and his two machine security guards guarding outside the west gate.

The remaining 24 machine guards are still patrolling the outermost perimeter, keeping snakes and insects away and preventing unauthorized access to the mine!

"BOSS!" Wu Guang saw Wang Hao coming, and immediately stood up and saluted.

Wang Hao nodded and said, "Scott, Div, Glenn will come over in front of the container truck, and you beckon them to transport the water pipes to the truck transporting the mine." ”

Wu Guang, the leader of the machine detachment, responded: "Yes, BOSS!"

Wang Hao selected a suitable place for water discharge pipes and parking outside the West Gate, called out the system, and manufactured 15,000 water guard water pipes with a length of 4 meters and an outer diameter of 22 cm in batches.

In order to facilitate loading, Wang Hao also deliberately packed these water pipes in bundles according to the size of the truck, and then only needed to drive a small crane to easily load and unload the truck.
