EN10217-7 AISI 304/304H heat exchanger stainless steel tubing with size 25.4x1.65mm
SPEZILLA TUBE supplies welded tube per ASTM A 269, ASTM A 249 or as rolled and welded. We supply common grades of stainless such as 304/304L and 316/316L in standard tube sizes and wall thicknesses, as well as more challenging stainless welded tube requirements including 304H, 316H, 309/S, 310/S, 317/L, 321/H, 347/H, 410, 410S, Duplex 2205, Duplex 2507, and more.
We can even supply material with wall thicknesses up to 3″ thick! Diameters sizes range from 1/8″ up to 96″. All welded tube products can be cut to size. Specialty testing services can also be provided. Stainless tubes can be polished per request and cut to size.
All of the stainless steel welded tube we produce begins its life as a welded tube. From there, we can do additional processing to the tube to reduce or essentially eliminate any evidence of a weld seam, or to achieve other goals such as very tight and consistent tolerances. Our welded and drawn over mandrel tubing is nearly indistinguishable from seamless tubing, and is often used as a less expensive substitute. Our five types of tubing are:
1. As Welded
2. Outer Diameter Conditioned
3. Bead Hammered
4. Cold Drawn Outside Diameter
5. Welded & Drawn Over Mandrel
6. Power generation
Alloys 304 (S30400) and 304L (S30403) stainless steels are variations of the 18 percent chromium – 8 percent nickel austenitic alloy, the most familiar and most frequently used alloy in the stainless steel family.
High strength, excellent corrosion resistance and minimized carbon content make Alloy 304 and 304L Stainless Steels useful for applications where welding is required. Uses include architectural mouldings and trim, welded components of chemical, textile, paper, pharmaceutical and chemical industry processing equipment.
Other advantages are its resistance to oxidation, excellent formability, ease of fabrication and cleaning, excellent strength to weight ratio and good toughness at cryogenic temperatures.
For severely corrosive environments,the lower content of Type 304L is preferred because of its greater immunity to intergranular corrosion.
