Characteristics
Heat exchanger tubes in the oil and gas extraction industry require very precise standards for the outer diameter. The inner welding seam has a max of 0,05 mm for rolling in the tube sheets. To increase the corrosion resistance of the tube, we apply solution annealing. An intensified eddy current test ensures extra security in relation to the leaktightness. A pneumatic or ultrasone test is also possible. The tubes are perfectly round to use in extruded finning.
