matter which might effect the quality of the weld and the cut surface shall be ground to a smooth

bright uniform surface by removing approximately 0.5mm of metal.

After grinding the weld ends shall be visually examined to ensure freedom from defects.

9.3.3 Heat Treatment

All pipes, fittings and flanges shall be furnished in the heat treated condition. Heat treatment may

be waived in the case of cold formed bends, where unallowable deformation may occur as a result

of quenching. This shall be in agreement between parties concerned and to be discussed for each

individual case.

The surface of the pipes and fittings shall be cleaned, pickled - passivated, so as to remove any

dirt, stains, scale, etc. and to yield an uniform surface condition.

Flanges shall be completely machined. Surface treatment by grinding can only be performed after

approval from Company.
