Apart from drilling regular Borewells of 4½” to 8½”, Al Shlaalat Drilling Est. is capable of taking Rotary Drilling & Earth Points also.

Al Shallalat Drilling is an inhouse specialist in super fast high power rigs. We also undertake installations; repairs of all types of .Borewells, Rotary, Earth Point, Cleaning, Yield testing etc. Earth Point is done up to 4” to 15”.

Drilling is done in all soils including clay & rocks. Our service is also available where vehicle facility is limited.

Another peculiarity of Drilling Borewell inside an open well will alsobe successfully handled by our well experienced crew.

Our services has been associated with the various types and diameter of borewell tubewell / handbore drilling and rig supply in industry of UAE for over 15 years.

All our percussion tools, backed with support vehicles andancillary equipments,staffs and machinery are working in a 24 x 7 manner even in shifts.

Earthing Methods:

A. Earthing to Water Main:

First the cold water pipe is thoroughly cleared of all grease and dirt. An adjustable clip is fixed at the cleaned spot. One end of the earthing cable is fixed to a lug which is attached to the clip by a fixing bolt and nut, tightening the nut draws the clip tight to grip the pipe firmly. The other end of the earthing cable is similarly connected to the conduit with a clamp and lug.

B. Pipe Earthing:

A galvanized iron pipe 38 mm in diameter and 2 meter long is driven into the ground or a copper plate of adequate size buried edge wise in the earth is used as the earth electrode. Its resistance must be kept below specified limit, packir % salts and powdered coke or charcoal to a depth of 30 cm, all around the pipein low resistance, keeping the earth moist by pouring water in to the pipe. According to the Electricity Rules, the frame of all motors, transformers etc and the metal casings of all power consuming equipments shall be earthed by two separate and distinct connections with earth. On electrical appliance the manufacturer provides an earthing terminale. The foundation bolts used for hold down the machines are often used for eathing them.

C. Plate Earthing:

The earth connection can be provided with the help of a copper/G.I. plate. When G.I. plate is used it should not be of less than 60 cm x 60 cm x 6.35 mm. The plate is kept with its face vertical at a depth of 3 m and is so arranged that it is embedded in an alternate layer of coke and salt for a minimum thickness of about 15 cm in case earthing is done by copper plate and in coke layer of 15 cm if it is done with GL Plate- The earth wire is securely bolted t0 the earth plate with the help of bolt nut and washer. Installed grounding systems and earth ground systems in such facilities must be visually checked to assure continuity, but must also be checked with instruments to determine the ground resistance potentials of the systems and that they will perform as designed. New construction must be verified through Quality Check processes to assure that systems are installed to specification and design. Modifications and / or repairs must be checked against specifications and drawings to assure elements are correctly re-installed, and composed of correct materials.

Some common ground failures are:

• Failure to electrically bond cable tray, pipe flanges, equipment bases, discharge nozzles.
• Failure to bond vessel, equipment, or process ground to installed ground grid or structural grounds
• Failure to assure adequate ground grid and potential distribution for the magnitude of the process or equipment involved, resulting in ionization potential.
• Failure to isolate control equipment from ionization potential of processes and vessels, or from RF energy.
• Failure to consider ionization potential from induced voltages associated with high voltage equipment, power lines, or generators operating near metallic alloy processes, vessels, and equipment.
