· 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-CIII 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-CIII is designed for condensing refrigerants.  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-CIII especially suitable for shell and tube-side condensers.

The OD enhancement, the ID ridge count, and the configuration have been modified to improve both the OD and ID heat transfer coefficients while simultaneously reducing the weigh per unit length, providing less water-side pressure drop.

Where there is a need for a low ID pressure drop, the tube is supplied with a smooth bore.
