Description:

?

Dual certified seamless?stainless steel tubing?of grades?304/304L &?316/316L are the workhorse grades for a variety of instrumentation and hydraulic applications. This material is stocked in 20 foot lengths in both welded and seamless production forms. Spezilla?maintains extensive inventories in a wide range of instrumentation tube sizes in all of our warehouses.

?

1. No harder than Rockwell 80 seamless stainless steel tubing.
2. Tolerance ASTM A269
3. Capped tube ends
?
Material and Method of Manufacture:
Spezilla seamless stainless steel tubing?is generally Dual Grade where possible. Dual Grade means alloy with identical physical characteristics and only slightly different chemical characteristics are specification- controlled favoring the grade with the more refined chemical characteristics.

?

Surface Finish:


ASTM specifications are ambiguous on the subject of finishes. Instrumentation tubing should be free from nicks, gouges, and deep scratches which can interfere with proper sealing, particularly in gas service. Spezilla seamless stainless steel?tubing?incorporate packaging and preservation standards which ensure that the tubing arrives in proper condition for use in instrumentation systems.

?

Hardness:


All instrumentation tube fittings require that the tubing be softer than the fitting material. While most metal tubing is restricted to a maximum hardness measured on the Rockwell hardness scale, Spezilla seamless stainless steel tubing?has a lower restricted maximum hardness. This restricted tolerance control lowers installed cost by allowing the tubing to be more easily bent and installed.
