DOM(Drawn Over a Mandrel)is a process that is applied to tubing after it is initially constructed. It giving more exact dimensions relative to the inside and outside diameters, a smoother finish, and better alignment of the crystal lattice structure. DOM tubing is a kind of precious tube.Although it is almost always referred to as a seamless tube, technically it is NOT seamless tubing, and it started life as some sort of EW (electric welded) tubing. During the manufacturing process, the weld line becomes nearly undetectable, thus it is referred to as SMLS. It is considered a high strength, high quality tube, and is normally constructed from SAE 1020 ,1026 steel or ASTM A513 Type 5 (EN10305-2).
