What Is Wet Sandblasting Technology?

 Wet blasting is a technique for surface preparation using water, abrasives and compressed air.

"Wet blasting" refers to a technology that uses the power of compressed air to spray a mixture of water and abrasives at high speed to achieve surface cleaning, processing and modification of metals, plastics, ceramics and other materials. Since it is wet processing, it is also suitable for fine processing using abrasives as small as several microns.

Advantages of wet blasting 

Wide selection of abrasive grain sizes, shapes, and materials
Because the abrasive particles are carried by water to the target, finer particles can be used compared to dry blasting.

High fluid control and controllability
The grinding fluid mixed with water and abrasive grains can realize fluid control, so the processing precision is higher.

Less abrasive residue
After machining, the abrasive particles are washed away by water, so fewer particles remain on the machined surface.

Capable of handling ultra-thin targets
The processing pressure is small, and the ultra-thin target will not be damaged during processing.

Adding chemicals can get the effect of secondary treatment
Chemicals can be dissolved in water, and chemical treatment can be performed at the same time as sandblasting.

The principle of wet sandblasting

Wet sandblasting is an easy-to-automate and environmentally friendly way to circulate the grinding fluid. Check here to know wet blasting machine.

The basic principle of wet sandblasting is as follows. The grinding liquid (mixture of water and abrasive) in the grinding liquid tank is drawn to the sandblasting gun by a pump and is sprayed onto the target material by the action of compressed air in the sandblasting gun. The grinding fluid is recovered to the grinding fluid tank for recycling.

“Minimally Invasive Operation”For Laying Urban Pipe Network -- Brief Introduction of Horizontal Directional Drilling Rig

“Zipper Road”

We often find that in the city where we live, roads are often dug up. Whether newly built or used for a period of time, we always feel that the roads around our residence have never been intact. We dig and repair them every day, it is not convenient to travel, but also causes environmental pollution, the phenomenon of digging out a part of the road is also known as the “Zipper Road”.

The main reason for this type of Zipper is not only that the road is damaged, but also that the road was not well planned when it was built, and with the rapid development of the city, the existing underground pipelines can not keep up with the demand of the city, in addition, some new pipelines also need to cross the road.

A few days ago, I saw a news report that a certain place has stipulated that the newly-built urban roads should not be dug up for 5 years after they are delivered for use. This will effectively put an end to the phenomenon that urban roads are often dug up. It will also avoid the economic losses caused by the repeated occurrence of “Zipper Road”.

But at the same time, it puts forward higher requests to the construction of the underground pipe network of the city road.

Horizontal Directional Drilling Rig

Do you often see a machine at work in the city's green belt, or on the sidewalk, inserting a rotating iron pipe into the ground to make a hole, and not far away inserting cables and pipes into the hole made by the machine, this machine is the horizontal directional drilling machine.

A horizontal Directional Drilling Machine is the mechanical equipment for laying underground pipelines without the need to excavate the ground. It can avoid obstacles successfully within a certain radius of the ground. It can be operated in underground strata such as clay, sand, and so on. It is widely used in electric power, flexible pipeline laying in the fields of communications, oil, and natural gas.

Unlike road closures and major road repairs, horizontal directional drilling rigs can be built on the side of the road without affecting traffic or people’s normal travel, as we often see.

Through the advanced HDD drilling equipment calculation and positioning, can let the whole drill through the process of bypassing obstacles to reach the intended location, to ensure the construction accuracy.

Compared with the traditional construction method, horizontal directional drilling has many advantages such as high construction efficiency, low cost, no environmental impact and so on.

Development Course of Horizontal Directional Drilling Rig

Horizontal Directional drilling is a new construction method that combines the common pipeline laying technology with the drilling technology used in oil exploitation.

When the horizontal directional drilling machine was not invented, it was not only inefficient but also costly to dig holes and sink pipes when laying pipelines to cross rivers or obstacles.

THE ADVENT OF THE HDD DRILLING MACHINE

Horizontal Directional drilling first appeared in the United States, in the 1960s, an American engineer used oil field directional drilling technology in the pipeline.

Later, reaming technology was invented, which also made it possible to lay large diameter pipes, and a new horizontal directional drilling technology was formed.

THE HDD DRILLING MACHINE DEVELOP IN CHINA

China first introduced this horizontal directional drilling technology in the 1980s. With the rapid construction of crude oil pipelines and urban pipelines in recent decades, horizontal directional drilling has developed rapidly in China, both the length of the crossing and the diameter of the pipeline have set many records.

We all know that it takes a lot of skill to extract oil, and that’s because it’s buried in the ground where you can’t see it, and it takes a lot of hard work to extract it.

In the exploitation of the first need to carry out very important drilling work, but also according to different geological and use different methods to drill wells, so as to obtain oil resources.

ADVANTAGES OF HORIZONTAL DIRECTIONAL DRILLING TECHNOLOGY

The traditional method of drilling wells is usually vertical drilling, but in many cases, horizontal drilling in the ground is used to find oil. This technique uses advanced acoustic and Gamma-Ray functions on the drill bit, when drilling, the data in the formation is collected by the bit and transmitted to the ground operator, so that a more ideal drilling plan can be adopted in real-time, and the bit can be controlled to bend forward in the ground at will, that would be like installing a clairvoyant on an underground drill that would eventually find oil.

Since the appearance of the horizontal directional drilling technology, the human drilling technology has improved a step, improved the production efficiency, and reduced the engineering risk.

With the requirement of energy-saving and environmental protection getting higher and higher, horizontal directional drilling rig, a kind of trenchless pipeline laying equipment, will be used more and more widely. Check here to get HDD drilling machine price list.
