Iipayipi zingabonelelwa nge-primer coating (i-zinc-rich epoxy), i-hot-dip galvanizing, okanye i-3LPE/FBE xa iceliwe.
2. I-ASTM A53 Ibanga B: Ukwakhiwa kwezinto kunye neempawu zokusebenza
I-ASTM A53 Grade B ludidi lwentsimbi yekhabhoni kwipayipi edibeneyo nengenamthungo. Igubungela iintlobo ezintathu: Uhlobo F (i-furnace butt welded), Uhlobo E (i-electric resistance welded – ERW), kunye noHlobo S (ingenamthungo). Kwimibhobho ye-LSAW, sibhekisa kuHlobo E okanye uHlobo S? I-LSAW yi-arc welded engaphantsi komhlaba, engagutyungelwanga ngokucacileyo yi-A53, kodwa i-A53 ivumela ezinye iinkqubo zokuwelda xa kuvunyelwene ngazo. Ngokwesiqhelo, imibhobho ye-LSAW ye-A53 Grade B iyamkelwa kwinkonzo yolwelo oluphantsi kunye nolwelo oluphantsi olusekelwe kwiimpawu zoomatshini.
