United Industries has over 80 years of experience producing both ferritic-grade and austeniticgrade stainless steel tubing for automotive industry applications. Production of a wide variety of laser welded, stainless alloys is available.
United Industries specializes in the high-quality tubing required for severe fabrication applications, including tubular manifolds, crossover and downpipes, spun catalytic converters, muffler/resonator components, and tailpipes.
Manufacturing
All tubing is produced in a true inline/work cell environment that minimizes work-in-process problems
common among most batch-type manufacturing. Raw materials are purchased in wide coils and slit
to width. The tube production begins with roll forming, then laser welding, weld bead conditioning,
inline induction or hydrogen bright annealing (when specified), final sizing OD stencil (if required),
cut to length, deburring, polishing (when specified), and packaging for shipment.
Polishing
Polished tubing has become increasingly popular for visible exhaust components. Inline polishing
is available ranging from 180-grit satin type to a high-luster super buff finish. All tubing is paperprotected
to ensure the ultimate surface condition during shipment and customer handling.
Quality/Testing
All United Industries’ tubing is tested to ASTM and customer fabrication requirements by the
operator of each work cell. Tubing is 100% eddy current tested, and destructive tests are
performed at regular intervals. Incoming raw material is inspected and must conform to our rigid
standards set for all our suppliers. Final dock audits are made to ensure consistent quality.
