Overview

Ultra High pressure water jetting machine is the preferred method on projects where large amounts of abrasives must be collected and disposed.

Several studies have shown that surfaces which have been water blasted with super high pressure water blasters . Watex machine is more better than those jetting with traditional solid abrasive methods.

Ultra High Pressure water jetting machine is very useful for any business that needs water blasting equipment. To begin with, Watex will reduce the overall cost of the operation, since the overall hydroblasting project duration become shorter (which leads to reduction of the overhead expenses). And no costs occur for the removal, storage and containment of the media.

Moreover, ultra high pressure water jetting machine provide a cleaner surface to coat, resulting to longer lasting coating.

It is commonly accepted that surfaces that have been water blasted with super high pressure jetters have a significantly lower level of residual chlorides (salts) which allows better coating adhesion and longer life.

Watex also abolishes the possibility of media contamination that can potentially reduce the profits. Such as grit contamination of turbines, compressors and deck equipment, sensitive and equipment with bearings.

When it comes to speed, it has been already mentioned that, the total project time is reduced. Watex UHP water jetting machine operates at such high pressure that leads to increased productivity. In general, Watex allows immediate completion of work less mess inspection.

What is the application of the ultra High Pressure Water Jetting Machine

High pressure Water Jetting Machine media

The use of water is a technique for cleaning surfaces, which relies solely on the energy and force of water striking a surface to acheive its cleaning effect.

In principel abrasive is not used in waterblasting systems, hence, the problems caused by dust pollution .And by the disposal of spent abrasives are eliminated.

Surface condition after water jetting

When large areas are water blasted, flash rusting which demolish the original surface standard may occur, before painting can be carried out.

The degree of flash rusting depends on many factors .Such as humidity level, temperature and the length of time the surface is exposed.

Small quantities of light tan-brown rust will partially discolour the original steel surface. The discolouration may be evenly distributed, or in patches, but it will not be heavy enough to mark an object brushed against the areas.


Medium flash rust : a layer of light tan-brown rust will cover the original steel surface after high pressure water jetting machine

This layer may be evenly distributed or in patches, but it will be heavy enough to easily mark objects brushed against the areas.
Heavy flash rust : a heavy layer of dark tan-brown rust will be completely covering the original surface. This layer will be evenly distributed and will easily mark objects brushed against the areas.

Temperature rise when UHP water blasting

The use of water jet blasting will cause the temperature of the steel to rise. The increase of temperature of the steel surface can be substantial. Depending on the pressure of the equipment used and will help water blasted surfaces to dry off faster, hence reducing the degree of flash rusting.

Removal of foreign elements with high pressure water jetting machine


The use of water has the advantage of removing oil and grease from the surface along with salt deposits. This is a major plus point of water jet blasting equipment . The grey, brown to black discoloration of corroded and pitted steel after water blasting cannot be removed by further blasting. Studies shows that this thin film consists of mainly ferric oxide, which is an inert material. As it is tightly adherent, it does not present a serious contamination problem.
