CS / ALLOY TUBE & PIPE

CARBON STEEL / ALLOY STEEL TUBES & PIPES

Carbon steel tube and alloy steel tubues are the most common grades for Heat exchanger, Condenser and Air cooler fabrication.

Depending upon our customer's need, we provide most competitive solution with various options such as stock delivery for shutdown within 24 hours response but also in new production basis as per client's purchase order subject to required length and grades.
