Drill Pipe Considerations for HDD Projects

Horizontal directional drilling, or HDD, is a trenchless technique for installing underground pipes. The pipes are installed along a bore path with a surface drilling rig, and done correctly minimizes impact on the surroundings. HDD is often used when trenching is not practical, and works with many soil conditions. At Corpac Steel Products, we are drill pipe manufacturers who understand the special needs of HDD projects.

Physical Properties That Must Be Considered

Drill pipe for HDD projects must be of the correct diameter, with an appropriate wall thickness, and the proper grade of steel for the conditions. Torsional stiffness is important for extended reach projects. With wall thickness, generally thicker means stronger, but there are exceptions. Modern steel alloys address the HDD project's need for pipe that's tougher. Drill pipe manufacturers should have the knowledge to understand the needs of HDD projects so that there are no misunderstandings.

Choosing a Supplier

If you're purchasing new pipe for your HDD project, thoroughly examine the quality control standards of the drill pipe suppliers you are considering. You should also choose a drill pipe supplier with the necessary engineering expertise to understand why you need what you need. Drill pipe suppliers should be about more than looking up inventory and quoting prices.

Planning for Delivery

You're better off planning your drill pipe purchases far enough in advance to find the selection and availability you need. What you don't want is to have to make a choice of "good enough" pipe that's in stock. Evaluate suppliers early so that you can order far enough in advance to get the exact pipe you want rather than running short on time and having to choose only from in stock pipe.

What to Expect from Your Supplier

Choose a drill pipe supplier who can provide reference material about their products to help you make the best decision on drill pipe. They should also offer inspection reports and calculations that can help you choose wisely. Furthermore, your supplier should have extensive logistics expertise to help you keep your project on schedule and on budget. At Corpac Steel Products, we deliver more than just steel pipe: we deliver peace of mind.
