A drill pipe is the backbone of any directional drilling project. This hardy, handy tool may not get all the attention it really deserves, but one cannot deny that it plays a vital role in the success of a project, or its failure!
The drill pipe may be the unsung hero at the drilling rig but it is expensive equipment and it does cost money. A string of drill pipe could be extremely expensive, sometimes costing $25,000 or more (depending on the size, of course). Since the drill pipe is among the most expensive wear item for drilling jobs, buying it and maintaining it is a necessity.
The market is quite competitive and in spite of the downturn in the economy, the drilling market is booming. So, the demand for drill pipes is pretty high, and there are some factors to keep in mind before buying a drill pipe.
There are different kinds of drill pipes that one may buy, ranging from the most common integral forged pipe to the press and fit type. Just as people conduct research while purchasing other products, the same must be done in the case of a drill pipe too. For instance, the buyer must consider how much power the rig has and what kind of rig they intend to use with the pipe. If the pipe and the rig do not match in size, the buyer is in for a lot of headaches besides waste of money. It is important to make sure that the drill pipe being purchased is strong enough for a particular rig or even for the particular application one has in mind.
It is important to use the right grade of pipe. A low quality pipe leads to a lot of fatigue resistance and this factor is highly critical in the drilling industry as the torque limits of the pipe is pushed right to the edge. Also, when drilling in a horizontal manner, there are a large number of cyclical forces at work.
When buying drill pipes, a percentage of customers always go with the price factor. However, buying cheap may not always be a great idea when it comes to a tool like the drill pipe. Some contractors tend to be a little shortsighted here, but one cannot get away with low quality pipe all the time. Tough conditions can test the strength of the pipe. If the quality of the pipe is low, disaster can strike at any moment.
Since drill pipes are expensive, it is important to take good care of them. Maintenance can maximize the life of the drill pipe. Even simple actions like rod inspection and regular cleaning yield good results. The string in the drill pipe must be inspected regularly to prevent failure of the string. Another important tip is to rotate the drill rods in the rod basket so that the same rod is not the first one to go into the ground always.
The above tips can help you make the right purchase and extract the most out of your purchase.
