Horizontal directional drilling (HDD), also called “directional boring”, is used in the underground construction industry and is a technique used when trenching or excavating is not practical. It is suitable for a variety of soil conditions and jobs including road, landscape and river crossings. E&M Supply Group can provide all of the necessary drill pipe for horizontal directional drilling at a very economical price.
Directional boring is an alternative process of installing or connecting utilities or pipelines in unsuitable environments.
HDD is also known as directional boring, road boring, or river crossing. The largest drills in this industry, or “maxi rigs”, are typically those that have over 200,000 lbs of drilling and/or pullback strength. These rigs are used on bores that start at around 1,500 ft in length, and go up to as long as 8,000’ in length. HDD maxi rigs use the same drill pipe that is used by the oil and gas industry. The most common drill pipe sizes used by maxi rigs are 5”, 5 1/2”, and 6 5/8” OD x 31ft long drill pipe. Smaller HDD rigs, on the other hand, use smaller and shorter drill pipe, and are used on bores that are less than 1,500 ft in length. The drill pipe that is used on these smaller rigs is also known as drill rod or drill stem and is unique to the HDD industry. E&M maintains an inventory of some of the more popular sizes of drill stem and drill rod, and we also represent some of the top drill rod and drill stem manufacturers in the country.
