Lithapo tsa epoxy fiber tse matlafalitsoeng tsa polasetiki tsa HP le li-tubing tse tlase li hlahisoa ka tumellano e tiileng le litlhaloso tsa API. Sehlahisoa sa selemo le selemo se fihla ho 2000km ka bolelele le bophara bo tlohang ho DN40 ho ea ho DN300mm. The epoxy FRP HP surface line e na le API e tloaelehileng ea likhoele tse pota-potileng ka thepa e kopantsoeng, eo ho hanyetsa ha eona ho eketsang bophelo ba ho sebetsa ha pipe.
