Packaging of heat exchanger tubes

(a) tubes bound with a steel band that has a paper underneath

(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.

Certified test reports for heat exchanger tubes

ASTM / ASME A450

EN 10204: for EN 10297 non specified testing (only the mandatory tests), 2.2

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
