According to GOST R 52318-2005, curvature and ovality are not set for pipes made in coils.
By agreement with the consumer, drawn copper pipes can be manufactured in coils of the following types:
- free winding coils (BT);
- coils of layer-by-layer ordered winding (BU);
- coils of flat spiral winding (BS).
Weight of pipes in coils with layer-by-layer winding
The mass of copper pipes in coils should not exceed 110 kg. The minimum and maximum masses of coils can be set by agreement with the consumer. By agreement with the consumer, the weight of the coils is from 40 kg to 70 kg.

Surface quality of corrugated copper pipes
The outside and inside of the copper pipes must be clean and smooth.
The inner surface of the pipes must be free of carbon film. On the inner surface of water pipes, the content of residual carbon should be no more than 0.20 mg / dm2.
LLC "Komtsentr Strategy" can manufacture corrugated copper pipes with diameters from 16 mm to 25 mm of any length.
Copper corrugated pipes must be airtight. Inspection of discontinuities is carried out using a flaw detector and testing by applying pressure to the pipe.
