If your job does not require the use of prime materials, you may want to consider using surplus pipe for
your next project. Not only will used and surplus steel save you in material costs, but it also keeps you
ahead of your competition

Common Uses for Secondary Steel Pipe

Secondary steel pipe has many applications. It is available in a variety of different lengths, dimensions and styles. Secondary pipe can be welded, painted, cleaned and cut to the exact specifications FOR your project. This type of steel pipe can be used to create sign poles, dock piles, pipe piling, road bore casings and other structural construction applications. It can also be used for barriers, bollards and bumpers, and for temporary staging work.

Common Topics Involving the use of Secondary Steel Pipe

Secondary is pipe that cannot be sold as “prime” pipe for one reason or another. It can be either new or otherwise unused pipe, such as excess steel pipe leftover from another project. There are a lot of ways to use surplus pipe in the construction industry. Anything that requires a dense under girding to add additional strength or needs to be shored up can use secondary or surplus steel, such as bulkheads or foundations. Similar to used steel, surplus steel pipe can also be used to build sign poles and fence posts, as well as culverts, bridge railings and other types of railings.

Where Does Our Secondary Steel Come From?

Some of the suppliers of secondary piping may surprise you. Because of laws and regulations regarding the classification and uses of used and surplus pipe in North America, much of it is new, unused, excess or lightly used. For example, excess pipe that comes from pipeline jobs that was used to replace worn sections by an energy or utility company qualifies as used or surplus, even if it was never used. This could include lengths of pipe that were never even cut prior to delivery.
Steel pipe that comes from milling operations that cannot be used due to repairs or issues with tolerance due to yields or chemistries can also be sold as surplus or used materials. Obsolete or surplus pipe that comes from various manufacturers and contractors throughout North America, however, is one of the largest suppliers of used pipe in the area.
Lastly, steel mills that manufacture prime steel pipe quite often generate pipe that for one reason or another is marketed as “excess prime,” meaning, quite literally, that it is brand new pipe but does not have mil certification or “pedigree” paperwork accompanying it, for marketing or other pricing/availability issues.

Where to Get the Best Prices on Used and Surplus Steel

When it comes to used and surplus steel, it helps to go to the experts. Steel Traders buys large quantities of new mill reject pipe from major pipe and steel mills throughout North America, and therefore is able to also buy surplus, reject, or excess prime pipe and steel from those same steel mills and significant cost savings that it can pass on to its customers. Furthermore, Steel Traders is a sister company of Oilfield Pipe and Supply.

The following Weld Procedure relates to all New Mill Reject material
welded to length with the incorporation of a "Backing Ring".

The circumferential weld joint configuration is Bevel x Bevel. The beveled ends for each spliced joint configuration are achieved by flame beveling. The beveled surface is ground with an abrasive grinding disc to remove any foreign or free materials as a result of the flame beveling process. No preheat is required since the base metal does not exceed .75 inches in thickness. The surface area on the base metal is free of any foreign solvents or materials prior to the welding process. The installation of a “Backing Ring” of .188 inches or thicker steel is at the base of the root opening. A joint root opening of .125 inches or .188 inches is maintained at the base of the root opening. A root pass is welded into the backing ring .045 inch MIG wire AWS A5. 18-79, class ER 70S-6 (gas shield wire). Upon completion of the root pass, the surface of the weld is ground with an abrasive grinding disc to remove any foreign or free materials as a result of the welding process. A multi-pass filler and cap weld is administer utilizing .045 inch MIG wire AWS A5.20/SFA-5.20 (flux core wire). The splice configuration is positioned on the horizontal plane directly in front of the welding operator and is rotated on mechanical energized rollers/manipulator. The “Backing Ring” remains in the welded member and is not removed, therefore no back gouging is necessary.
