3) HANDLING INSTRUCTIONS:
Pipes should be kept on an even surface while storing. They should be properly supported and should not be stacked for heights more than 1.5m for longer durations.
While laying big pipelines provision should be made for expansion joints, air vents and proper anchorage.
Pipes or fittings should not be cleaned with solvent cement. Quality of solvent cement plays an important role and hence it is recommended to use good quality solvent cement only.
For large diameter and higher class pipes (6 Kgf/cm and above) always use heavy duty solvent cement. Very old, hard, semi-fluid solvent cement should not be used.
