USER RESPONSIBILITY

Because design, fabrication, erection and cutting vari- ables affect the results obtained in applying this type of information, the serviceability of a product or struc- ture is the responsibility of the user. Variation such as plate chemistry, plate surface condition (oil, scale), plate thickness, preheat, quench, gas type, gas flow rate and equipment may produce results different than those expected. Some adjustments to procedures may be necessary to compensate for unique individ- ual conditions. Test all procedures duplicating actual field conditions.
