ʻO ka wehewehe ʻana a me ke kaʻina hana o nā paipu kila kalapona

ʻO ka Pipe Steel Carbon he paipu i hana ʻia me ke kila kalapona ma ke ʻano nui. Aia ma waena o 0.06% a me 1.5% ka nui o ke kalapona, a loaʻa kahi wahi liʻiliʻi o ka manganese, silicon, sulfur, phosphorus a me nā mea ʻē aʻe. Wahi a nā kūlana honua (e like me ASTM, GB), hiki ke hoʻokaʻawale ʻia nā paipu kalapona i ʻekolu mau ʻāpana: haʻahaʻa kalapona kila (C≤0.25%), kalapona kila kila (C=0.25% ~ 0.60%) a me ke kila kalapona kiʻekiʻe (C≥0.60%). I waena o lākou, ʻo nā paipu hao kalapona haʻahaʻa ka mea i hoʻohana nui ʻia ma muli o kā lākou hana maikaʻi a me ka weldability.
