Surface Cleaning & Peparation

Surface Cleaning & Peparation

Cleaning is the most common use for water at pressure, known as water jetting or hydro-blasting and is used regularly by KHIDMAH Industrial Services in tank cleaning and in spill clean ups. A high quality result is achieved by our experienced operators who are trained as a minimum to the Water Jetting Association Standard and in addition we conduct our own training including practical training from a senior supervisor.

KHIDMAH Industrial Services own a fleet of jetting units including trailers capable of providing High Pressure (HP) Water Jetting, Hot Water (Hot Wash) and Ultra High Pressure (UHP) Jetting Units all these are fitted with Spark Arrestors and Chalwyn Valves as standard allowing them to be used on all our clients’ sites. The pressure selected will be dictated by the construction of the tank including any tank linings, the product and the finish required for the next stage.

We have a variety of lances and nozzles for use on our fleet of high pressure units, the variety means we can select the most appropriate depending on the priority, be it a wider surface area to be cleaned or a more focussed jet for stubborn products.

KHIDMAH Industrial Services can also use water jetting to prepare a surface ready for maintenance. There are a variety of methods available and with investigation in to the tank construction the correct method can be chosen for each client’s needs. If the tank is to be relined using linings selected to meet the needs of the tank materials and proposed contents the application can begin on the newly prepared surface and the lining, such as an epoxy resin, can be applied in a timely manner for optimum adhesion. Similarly if the externals require re-coating using specialist paints selected to fit the purpose KHIDMAH Industrial Services can complete the project without delay.

We work with selected partners who carry out NDT testing and we would be happy to liaise directly with them on behalf of our clients to ensure no lost time as we could be in full communication with them on your behalf.

Specialist Cleaning

Specialist Cleaning

KHIDMAH Industrial Services are able to offer a range of specialist cleaning for Pipes, Heat Exchangers, Tube Bundles, Condensers and Fin Fans.

Commonly KHIDMAH Industrial Services are asked to clean the pipework associated with tank cleans and there are many different methods suitable depending on the diameter of the pipes and the product which has been transferred through them. In some instances mechanical techniques such as pigging can be suitable and KHIDMAH Industrial Services can supply this including the full range of equipment to carry out pigging of lines of most diameters. With more stubborn products mechanical techniques will only remove a proportion of the deposits and a liquid chemical phase is required to penetrate and lift the residue once this is achieved, a ‘water-wet’ barrier is formed on the metal which minimises re-deposition. KHIDMAH Industrial Services use as a range of cleaning agents and chemicals dependant on the product and can customise the decontamination and cleaning service to suit.

Heat exchangers and tube bundles are historically time consuming and dangerous to clean, but using the freelance system KHIDMAH Industrial Services can clean these quickly, safely and with minimum contamination. The trained operative using the freelance system can clean over 200 tubes an hour and due to the waste tube, which is located in the lance handle, the waste water can be directed where required and the kick back force of the water is safely controlled.

Cold Cutting

Cold Cutting

KHIDMAH Industrial Services are regularly asked to make cuts without generating heat either as part of a contract or as a standalone job to reduce the danger of hot work such as petrochemical fumes and with explosive dusts on a huge range of sites and may require improved access to a confined space or dismantlement of a tank or tower. Also if there is a situation where the danger of heat is unknown, such as a pipeline or under a tank floor, the worst case scenario needs to be assumed and safety has to be the top priority.

KHIDMAH Industrial Services have a number of systems for cutting each have benefits depending on the task at hand. They all work on the principle of water at pressure mixed with a cutting abrasive. This is an environmentally safe and heat free method of cutting through metals including steel at thickness up to 6 inches. Only top quality garnet abrasive is used ensuring a fast and clean cut with our experienced operatives ensuring health and safety using the equipment and of the task freeing the released part.

With the selection of cutting units, heads, nozzles and tracks available we can ensure that the combination used is suitable both for the material being cut and offer this at the best cutting time giving a time and cost saving for our clients.
