Chromium Carbide Overlay Coated Steel Wear Plates

Welldam wear plate are manufactured by welding one or multiple abrasion resistant layers on a medium or low carbon steel base plate. The overlay alloy has a high amount of chromium carbide hard particles. 
Thickness Range: 3-20 mm, Thickness error is ±0.3mm 

Our Wear plate has following advantages: 

1. Flat surface and nice outlooking 2. Outstanding welding strength

3. Excellent wear resistance 4. Excellent impact resistance

5. Easy processing 6. High Cost Performance

7. Comprehensive quality control.

HDD Hole Opener

First : PILOT HOLE DRILLING

The pilot hole is drilled from the entry point to the exit point following a previously designed profile and alignment. The Drilling Tools and rig equipment selected for each job is largely determined based on the results of the geotechnical investigation and the size of the crossing (length and diameter). During the pilot hole drilling, a directional guidance system is used to navigate the pilot hole along its pre-designed profile. Marine Support including vessel and dive crew management is essential on Shore Crossing Projects.

Second : HOLE ENLARGEMENT

In small diameter crossings the pipeline may be directly installed in the pilot hole. However in most cases pilot hole enlarging, known as [pre-reaming," will be necessary. Pre-reaming is required to provide a bore diameter large enough so that the pipeline can be installed in the drilled crossing. Based on the final desired diameter and soil conditions this process may include one or more stages.

Third : PULL BACK

Once the drilled hole has been enlarged to the required diameter and cleaned adequately, the pipeline is installed. When applicable, the pipeline is pre-assembled in a single string and placed on rollers prior to pullback. For pullback, a reamer is connected to the Drill Pipe. Behind the reamer a swivel is connected allowing the drill pipe to rotate the reamer without allowing the transfer of torque to the product pipe. The drill pipe is then pulled back towards the entry point until the pipeline is fully installed.
