Hydrojetting Services

At present Al Fahhad Zegwaard Co. are equipped with following Hydro Jetting Machines:

10 H.P. Pumps with working pressure of up to 10,000 psi
3 H.P. Pumps with working pressure of up to 15,000 psi
3 H.P. Pumps with working pressure of up to 7,500 psi @ 208 F water temperature

All Hydrojetting Machine

All Hydrojetting Machines are equipped with all the necessary accessories such as jetting gun, foot pedal,jetting hoses, flexible lances, rigid lances, nozzles, and safety gear, to execute all kinds of Hydrojetting jobs. The Hydrojetting equipment is regularly pressure tested by third party(s) and test certificates can be submitted upon Client request.

For today’s toughest industrial cleaning problems we can provide powerful Hydrojetting machines to carry out cleaning jobs once considered “impossible”. Whatever built up chemical residues; paint, tar deposits, rust, scale, Al Fahhad Zegwaard Co. Hydrojetting machines cuts through it! Jets it away and leaves a clean residue free surface. Al Fahhad Zegwaard Co. provides Hydrojetting services since 1986 with pumps capable of producing pressures in excess of 10,000 psi, which is widely accepted by the industry as a safe and economical means of cleaning. Hydrojetting; a specialized operation with proper equipment and well trained and experienced operators (usually 2 – 3) fully equipped with the necessary PPE that reduce downtime and maintenance cost. For cleaning surface areas contaminated with oil, grease, jell, drilling mud, etc. our high pressure steam cleaners with a water temperature of 208 F, will leave a clean area without the usage of chemical cleaning agents. Ultra High Pressure Hydrojetting is the fastest growing surface preparation system in the Marine, Petrochemical and Refining Industry both on-shore and off-shore

Al Fahhad Zegwaard Co. Heat Exchanger Maintenance Includes:

All work is performed in compliance with strict safety rules and regulations, by our experienced hydroblast operators whom are trained at our Dammam facility.

Power Lance

The power lance is rigid lance fitted to a X-Y frame to safely unplug tubes which are completely plugged with hard scale such as calcium sulfate or calcium carbonate of condensers, heat exchangers, and reboilers.
The lance does not require external power source. It utilizes the water flow and pressure up to 10,000 psi from an existing hydroblast unit. The rigid lance will erode, extrude or shatter all fouling materials which plug the tube with a maximum length of 6 meter per run. The special designed nozzles / tips with various patterns have most jets pointed forward.

Flexible Lance Machine (OAB II)

The 2-flexible lancing machine, is fitted with two (2) ⅛” flexible lances coiled on a air operated hose reel. A flexible lance guide can be adjusted to the correct pitch of the tubes and the hose reel set to the correct length of the tube bundle.

Advantages of the Flexible Lancing Machine are:

  • Safer tube cleaning operation. The operator does no longer come in contact with the flexible lance(s) and
    Pollutants omitted from the high pressure cleaning of heat exchanger tubes.
  • Reduces downtime / reduces cleaning time due to the fact that two (2) are used simultaneously and the
    nozzle pattern (jets are pointed forward).

Drill Lance

The air powered drill lance can be fitted in the X-Y frame of the power lance and can be operated to working
pressure of up to 20,000 psi. The air motor can push the rigid lance in the tube and a second motor turns the
