Special ACR & Refrigeration Tubes

Kanak Pipe Industries stands at the forefront as a prominent manufacturer of specialized ACR (Air Conditioning and Refrigeration) Copper Tubes in India. Specifically, ACR Copper denotes a durable, hard-drawn rigid pipe with a length of 20 feet, tailored for applications in commercial settings such as refrigeration or chill water piping.

The distinct advantage of employing ACR rigid copper lies in its suitability for projects featuring extended straight runs. This eliminates the need for additional labor to straighten rolled copper, mitigating the risk of overbending and potential distortion that could lead to pipe tears and subsequent leaks.

ACR Copper Tubes (ACRCT) find indispensable use in the Air Conditioning and Refrigeration Field Service Industry, designated by the tube’s actual Outer Diameter (OD). Notably, only hard-drawn ACRCT is color-marked, distinguishing it from annealed variants. These tubes serve a crucial role in facilitating the efficient functioning of air conditioning systems by containing various refrigerant mediums. This, in tandem with refrigerant compressors and copper’s exceptional heat conductivity, enables rapid heat transfer, a fundamental aspect of air conditioning.

Given the pivotal role of internal pressures in ACR applications, it is imperative to adhere to the working pressures recommended by the Copper Development Association. These recommendations, in conjunction with the ASTM’s (American Society for Testing and Materials) Standard Specification for Seamless Copper Tubes, provide essential guidelines for ensuring the reliability and performance of ACR Copper Tubes in diverse applications.
