• Sewage treatment

Tube Tech manufactures Plain and finned U – Bent tubes in Copper, Brass, Cupro Nickel, Stainless Steel & Carbon Steel tube materials, according to various heat exchanger standards or to customer's specifications. During U Bending of finned tubes, the Bend portion is generally left unfinned during finning operation to accommodate smooth bending. The Finned U Tubes are produced, controlled and measured in accordance with SB 395 & TEMA standards.

Both Plain U Tubes and Finned U Tubes are hydro tested after fabrication against any surface defects / leakages. We have in house stress relieving facility and these tubes can be heat treated for stress relieving, if required by the Customer. We can offer a range of additional testing on request, including dye penetrant and PMI testing.

U Tubes are cut to the specified leg length, ends deburred and internally cleaned with dried air before final inspection & packing. Each bundle is protected with plastic sheets. Detailed packing lists are attached to boxes to give quick and clear identification of contents.
