GENERAL INFORMATION:
A wide range of fittings and special pieces can be manufactured in G.R.P. They present, therefore, the same characteristics, both chemical and mechanical of the pipes. Fittings are manufactured manually employing male moulds or pipes pieces to be joined together. Ends of fittings can be bell and spigot type provided with sealing gaskets or plain type to be by welding to adjacent pipes or other fittings. The normal production includes:
-different degree bends (by moulds or pipe pieces)
-equal tee or reduced tee (by moulds or pipe pieces)
-concentric and eccentric reducers (by moulds)
-fixed flanges and stub end (by moulds)
-blind flanges (by moulds)
Moreover, other special pieces such as manholes, flanged pipes equal and reduced tees etc. can be manufactured by welding together fittings and/or pipes sections.
