High-conductivity, corrosion-resistant copper tubing
BK Industries manufactures UNICOP™ copper tubes at our plant in Palghar, Maharashtra, near Mumbai, and supplies buyers across India. We make round copper tubes from 1/4" to 4" OD and square copper tubes from 3/8" to 2", including copper tubes for earthing and lightning arresters and EC grade copper tubes for cable lugs.
Our seamless copper tubes offer high electrical conductivity, high thermal conductivity and excellent corrosion resistance — used in HVAC, earthing, water heaters, heat exchangers and industrial applications, as well as water and gas lines. BK Industries supplies round and square UNICOP™ copper tubes in straight lengths, in the tempers your process needs.
Alongside phosphorus-deoxidised (DHP) copper, we make EC grade (electrolytic copper) high-conductivity tubes, mainly for cable lugs and electrical terminals. Tubes are supplied in straight lengths up to 18 ft (approx. 5.5 m) or cut to size, with cleaned bores and end caps where required for ACR and heat-exchanger use.
