Important technical terms
Seamless stainless steel tubes are generally ordered according to delivery standard(s). The respective delivery standard defines the labeling text (e.g.: manufacturer - material number - dimension - cast - execution - ...), which is applied to the tube surface (complete tube length). In addition to these standard specifications, the customer can define further labeling data.
In steel production, a sample is taken from each cast (ladle) and analyzed in the laboratory. Thus the content of the alloying elements, the oxygen activity, the degree of purity, etc., are determined.
That means a plastic sheet enforced with a texture, which protects the packaged product from contamination during transportation.
