Product Information
Welded Stainless steel pipe
Welded and drawn is the preferred tubing choice in terms of economy, lead time and tolerancing compared to seamless in most instances.
On our welded and drawn tubing line, we offer:
Lowest minimums in the industry and competitive pricing
In-stock random lengths - typically ship same day of order if placed before 1pm EST
Hundreds of thousands of feet of unlisted non-standard sizes in stock
Custom tubing you need---cheaper, faster and better than the others

A WORD ON OUR WELDED AND DRAWN PROCESS...
The flagship lines of stainless steel and alloy tubing for hypodermic needles provided by Haohua Industry Needle Company are manufactured using the T.I.G. (Tungsten Inert Gas) welded and plug (floating or mandrel) drawn process with full hard temper (typically 150 KPSI minimum). This process has been the "gold standard" for all medical grade tubing for hypodermic needles since the 1960's. The significant amount of cold work put into the material from the drawing process results in the best finishes and hardest tempers (tensile strength) achievable. Burr removal is easiest in the full hard temper condition as chips break off versus "gummy bending" at lower tensile strengths.
