What Is Hydro Jetting?

Water jet cleaning, or hydro jetting and sometimes with special fluids under a certain pressure and with the required feed rate, is a type of preparation of surfaces for various purposes for further processing. 

There are various reasons why you might need to hire a hydro jetting company in order to clean your drains. You may have seen them in action at airports, or heard about how they are used to clear roads after floods and snowfalls. 

The reason that they are so powerful is because they use an extremely high pressure stream of water instead of using harmful chemicals. This means that they can remove dirt, mold, grime and even old paint without damaging your driveway or patio. Once you see how well it works, you’ll never consider doing these types of cleaning jobs by hand again!

The hydro jetting method removes contaminants of various origins. It can be rust, scale, peeling paint, outdated plaster, resins, bitumen, etc. The method is used in construction in the preparation of building facades, including the removal of graffiti and inter-slab seams, in mechanical engineering and shipbuilding, in the construction of hulls and technological equipment, in aviation to remove traces of rubber from runways, etc.

In this way, tanks, heat exchangers and pipe structures are cleaned from scale, deposits and contamination both inside and outside. 

The essence of the method: a jet of water under pressure acts on the surface, tears off and carries away particles of unnecessary materials from the surface. Thus, it cleans from dirt and deposits, and with the use of special compositions it also degreases. Hydro-jet cleaning of metal structures is especially popular, since it allows them to prepare them for painting in an environmentally friendly way. 

In this article we have discussed advantages of hydro jetting cleaning. Read on to find what benefits do hydro jetting provide. 

Advantages of Hydro Jetting

The hydro jetting method of surface preparation using water supplied under different pressures and at different speeds has the following advantages: 

  • The operation can be performed on materials of different origins; there is no thermal effect
  • Explosion and fire safety of work
  • High degree of purification
  • High speed of the operation
  • Cleaning can be carried out in hard-to-reach places
  • Absence of gas emission, i.e. The process is environmentally friendly

In addition, the hydro jetting cleaning method can be applied using liquids with surfactants, which expands the capabilities of the method. 

The method has only two drawbacks. Firstly, it can be performed only at a positive temperature, and secondly, the surfaces after irrigation with water need to be refined, since in this way the necessary profile and the required degree of cleanliness are not given. 

Unlike the hydro abrasive method, where a material of a certain hardness is fed together with a liquid, it is impossible to obtain a clean surface and cut. With its help, you can only get rid of contaminants of various kinds and origin, prepare a metal, plastered surface for the necessary technological operations. Purification degree 

The hydro jetting method is distinguished by several degrees of cleaning, which are specified in ISO 8501-4: 2006. It depends on the pressure of the liquid, which can be supplied in different ways to the surface to be treated. 

According to this principle, the hydro jetting method is divided into the following types (the unit of pressure measurement in MPa is indicated in the technical documentation and in the passport data for a specific installation):

  • super high (above 170); high (70 ÷ 170); 
  • medium (34 ÷ 70);
  • low (less than 34). 

Some major advantages of hydro jet cleaning are as follow 

  • Low cost of consumables – fresh water is used. If necessary, you can add liquid detergents to it.
  • High speed, quality and manufacturability of work.
  • Eco-friendly and no waste. The remains of some types of pollution are collected and disposed of, but in most cases no further cleaning is required – the water will dry out.
  • Explosion and fire safety of the work carried out.
  • The compact equipment can be used even in confined spaces.

The disadvantage of this method is only one – the impossibility of using at low temperatures, when the water freezes.

Equipment for Hydro Jetting

For cleaning, a manual or industrial set of equipment is used, which includes a pump or pump, an engine (gasoline, diesel or electric), hoses, nozzles, filters and accessories. The units are distinguished by their mobility and compactness. 

They are selected depending on the pressure and speed with which the liquid must be supplied to the surface to be treated. The units are produced by Russian and foreign manufacturers, with a water pressure of up to 2960 atm. 

At the same time, powerful devices include a special unit – a flow amplifier. As a rule, they are mounted on a trolley or platform. In the latter case, they are supplied with a control panel. Some hydraulic jet models are equipped with safety systems, pump cooling, pressure regulator, instrumentation, 

The best domestic water-jet cleaning units are considered products of the Poseidon series (manufacturer – ZET-TECHNO, Russia). Devices for universal use are assembled from components manufactured in the USA, Germany, Italy. 

They differ in layout, type of drive and its power, pressure, amount of consumed water per hour and the presence of additional functions. The installation kit includes a trolley or platform, a three-plunger high-pressure pump, a flow-through filter, a hose of a certain diameter and length wound on a drum, a nozzle, a gun and a spear. There are models with water heating. 

A powerful installation for flushing pipelines of various diameters and technological equipment can be purchased at the Svesky pumping plant. It is mounted on a mobile platform, and a feature of the model is the ability to regulate the amount of supplied water in the range from 2 to 8 m³ per hour and develop a pressure from 100 to 1000 kef / cm², which makes it possible to clean any kind of surface contamination of various types.  

Why You Need to Hire Hydro Jetting Cleaning Services?

Cleaning the surface with a high pressure hydro jetting has little to do with regular cleaning. Water supplied by a directed jet at a pressure of 1000-2500 bar easily removes not only old paint, but also a porous layer of concrete. 

High pressure water cleaning should only be performed by personnel trained and familiar with safety precautions.
