· External Standards

This product is produced in alloy C12200 to meet the mechanical, chemical, and testing requirements of ASTM B75/B359 and in alloy C70600 to meet the mechanical, chemical, and testing requirements of ASTM B466/B359.  For applications to the ASME pressure vessel code, the product will be produced to meet the requirements of ASME SB75/SB359 for alloy C12200 and to SB466/SB359 for alloy C70600.  Other applicable standards - DIN 1787, DIN 17671, DIN 17664, and ADW 6/2 WD TUV 420/5.

· Plain Sections

Plain end and land of 1" (25.4 mm) and over are standard.  For plain end and land lengths down to 5/8" (15.9 mm), contact the Wolverine Marketing Department.  Spacing between lands of 18" (457.2 mm) and over are supplied as standard.

· Lengths

Overall lengths, with power brush deburred ends, are supplied from 4' (1.219 m) to 60' (18.288 m) as standard.  Overall lengths, with chamfered ends, can be supplied from 3' (0.914 m) to 28' (8.534 m) as standard lengths.

ID/OD Enhanced Surface for Improved Boiling Heat Transfer

Turbo-ELP is designed for boiling of low pressure refrigerants.  The integral helical fins on the outside of the tube are modified to enhance the initiation of nucleate boiling sites, thus improving the over all heat transfer coefficient.  The inside heat transfer coefficient is improved over smooth bore products because of increased surface area and turbulation induced by integral helical ridges on the inside surface.  The availability of plain ends and intermediate lands makes Turbo-ELP suitable for shell and tube evaporators.  

The external configuration and the ID ridges have been modified in such a way to match the Turbo-BIII LP performance.
 

· Temper

Turbo-ELP is supplied as standards, in the "as finned" condition with plain ends and lands in the annealed condition.  Material can be supplied in the annealed condition the entire length by special request.
