The PRO-Fit Precision Flaring Kit is a pipe flaring tool for copper and aluminum tubing used in air conditioning and refrigeration work. It helps prevent potential sidewall splits and leaks associated with slow traditional flaring tools when forming 45-degree field-applied refrigeration tubing flare connections.
The easybend kit consists of four color-coded, industrial-grade, solid, polyethylene mandrel diameters. It is 13 feet long and fits quickly, but snugly, into soft copper lineset tubing sizes of ¼-, 3/8-, ½-, and 5/8-inch.
The International Copper Association Inc. (ICA) and Optimized Thermal Systems Inc. (OTS) announced a new technology outreach program on the design and use of heat exchangers made with MicroGroove™ smaller diameter copper tubes.
The International Copper Association (ICA) and Optimized Thermal Systems Inc. (OTS) announced that newly developed MicroGroove™ small-diameter copper tube correlations will be implemented in CoilDesigner® software, a proprietary heat exchanger simulation and design optimization tool.
Smaller-diameter copper tubes strengthened with low percentages of alloying elements can withstand the higher pressures of the new refrigerants such as CO2 (R-744), according to the International Copper Association.
Concerns related to soldering copper tube and the new no-lead copper alloys led the Copper Development Association (CDA) to conduct laboratory research and testing out in the field. The CDA found that, in many cases, those working with the new no-lead copper alloys were using the incorrect soldering procedure.
Aquatherm-to-copper stub-outs come in ½-, ¾-, and 1-inch diameters and range 11-18 inches in length. Installers can easily transition to a fan coil unit, zone valve, heat pump, or other HVAC components with sweated connections using polypropylene-random (PP-R) piping systems.
The copper tubing from five air conditioning units at the school was removed on Aug. 1, leaving the building with no air conditioning less than two weeks before the first day of classes.
When it came time to install the mechanical and plumbing system at the Nemours/A.I. DuPont Children’s Hospital in Wilmington, Delaware, the shape of the new building created some unforeseen challenges for the contractor.
