Tube Tech Copper & Alloys Pvt. Ltd.

Palghar, Maharashtra

The bimetallic tube is composed of two different materials - usually inner material is a corrosion resistant alloy (copper, aluminium brass or Cupro nickel) whereas the outer material is a high-stress resistant alloy (Brass, stainless steel or carbon steel). It is, however, possible to manufacture bimetallic tubes with any material combination as per the requirement & availability. In applications with high pressures and corrosive conditions, bimetallic tube permits large economical savings in comparison with a tube made of a single alloy, since the use of precious materials is reduced to the minimum. 

Bimetal tubes combine the positive properties of different materials for use in various media. Bimetal tubes are a safe and economical solution for heat transfer in aggressive media since expensive, corrosion-resistant materials can be combined with less expensive ones. We manufacture these tubes through the rolling & drawing process which gives flawless cladding between two different metal tubes.

In order to increase the area of the tube for better heat transfer, helical fins can be formed on outer tubes surface, if required. Fin density of 11 FPI to 26 FPI can be accommodated, depending upon the Customer’s specific requirement.

Turbo Chill Tubes is an integral low fin tube provided with spiral ridges on the inside. In a Turbo Chill Tube, the inside fluid heat transfer capability is remarkably improved in comparison with the smooth in-tube type tubes. By the effects multiplied mutually by the tubes outside fins and inside spiral ridges a high coefficient for overall heat transfer is obtained. These parameters significantly contribute to the reduction in size of various freezing machines. Normally, Turbo Chill Tubes are generally supplied with 8 & 10 starts configuration; however, it can also be fabricated with other number of starts on request. These tubes are fabricated in alloy C 12200 to meet the chemical, mechanical and other test parameters of ASTM B 75 / B 359 and in alloy 70600 to meet the chemical, mechanical and other test parameters of ASTM B 111 / B 359. BS EN, JIS and DIN standards are also available on request.
