ʻO 20G paipu kila maʻemaʻe he ʻano maʻamau o ka paipu kila ʻole. ʻO ka "20G" ma kona inoa e hōʻike ana i ka mea o ka paipu kila, a ʻo ka "seamless" e hōʻike ana i ke kaʻina hana. Hoʻokumu pinepine ʻia kēia kila me ke kila kalapona, ke kila kila, a me nā mea ʻē aʻe, a loaʻa iā ia nā waiwai mechanical a me ka weldability. ʻO nā hiʻohiʻona nui o ka 20G seamless steel paipu he kiʻekiʻe ke kū'ē i ka wela, ke kū'ēʻana i ka corrosion, ka ikaika compressive kiʻekiʻe, a me nā mea'ē aʻe.
