Wolverine Tube - Turbo-C

· 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 B111/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 SB111/SB359 for alloy C70600. Other applicable standards - DIN 1787, DIN 17671, DIN 17664, and ADW 6/2 WD TUV 420/5.

· Plain Sections

Plain ends and lands of 1" (25.4 mm) and over are standard. For plain ends and lands down to 5/8" (15.9 mm), contact the Wolverine Marketing Department.

· Lengths

End finish shall be chamfered or brush deburred as specified by the customer. If not specified by the customer the end finish will be at the discretion of the producing plant.

· Temper

Turbo-C is supplied as standard, 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.

An Improved Refrigerant Condenser Tube

Turbo-C is designed for refrigerant condensers. The integral helical fins on the outside of the tube are modified to enhance the condensing heat transfer coefficient. The inside heat transfer coefficient is improved 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-C especially suitable for shell and tube-side condensers.

Where there is a need for a low ID pressure drop, several sizes are available in Turbo-C. It may also be supplied with a smooth bore.
