(b) tubes wrapped in plastic sheets, burlap,
(c) tubes in wooden crates.
The tubes are supplied in packages with a circular or hexagonal outline with having weight of 300 – 2500 kg.
Testing of heat exchanger tubes
– prescribed mechanical tests,
– leak tightness test by eddy current,
– hydrostatic testing,
– ultrasound testing.

specified testing – 3.1.B
after agreement – 3.1.A, 3.1.C, 3.2
DIN 50049, – 2.2, 3.1. B
Straightness of heat exchanger tubes
Straightness deviation for the whole length of a tube L can not exceed value of 0.0015 x L. In conversion to the 1 meter length it can not exceed 3 mm.
Condition of delivery and surface of tubes
Tubes are supplied according to agreed standards. The cold drawn tubes after the final forming go through thermal processing in shielding gas – normalizing.
Surface protection of heat exchanger tubes
The inner and outer surface is protected by a light oil application. Upon request it may be protected with and easy removable oil application on the outer side. The tube ends may be enclosed by a plug.
