Welded Tubing

Welded tubing is produced by roll-forming strips or sheets into a tube shape, then welding the seam longitudinally. While welded tubing can be produced through either hot forming and cold forming processes, cold forming results in smoother finishes and tighter tolerances.

At James Duva, Inc., our stock tubing is bright annealed. Through a process of quickly heating in a closed, Oxygen-free furnace, then inserting Hydrogen or Argon gas and rapidly cooling, the tubing has a non-oxidizing protective layer on the outer surface which aides in resisting corrosion. The process maintains the smoothness of the surface, and results in a bright, shiny appearance.
Welded tubing can be a cost-effective solution for applications with lower working pressures. James Duva, Inc. supplies welded tubing that is reliable and durable, yet affordable.

Welded Tubing Affordability

Welded tubing is less expensive than seamless tubing. While seamless tubing is created through a time and labor intensive extrusion process which is required to make tubing without a weld seam, the welded tubing manufacturing process is, by comparison, extremely simple. Cost of production is low, and the tubing can be produced more rapidly.

Welded Tubing Versatility

Welded tubing is common use across many industries, primarily for low and medium pressure applications. The manufacturing process of forming from sheets results in consistent wall thickness along the length of the tube. For that reason, welded tubing is extremely reliable. It has superior concentricity to seamless tubing, high internal surface quality, and can be made with thin nominal wall thickness.
