Hoʻokaʻawale ʻia nā paipu kila i nā paipu kila ʻole a me nā paipu kila welded (seamed pipes).

ʻO ka paipu paila he ʻano o ka paipu ʻole. ʻO keʻano o ka hanaʻana ua like ia me ka paipu liʻiliʻi, akā aia nā koi koʻikoʻi ma nā pae kila i hoʻohanaʻia no ka hanaʻana i nā paipu kila. E like me ka mahana hoʻohana, hiki ke hoʻokaʻawale ʻia i nā paipu boiler maʻamau a me nā paipu paila kiʻekiʻe.

1) ʻO 20G, 20MnG a me 25MnG nā māka kila o ke kila kila kila kiʻekiʻe.

2) Alloy structural steel grades 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.

ʻO nā paipu kila maʻemaʻe no nā paila haʻahaʻa a me ka liʻiliʻi (GB3087-2008), Na paipu kila lauwili ole no na boiler kiekie (GB5310-2008), ASME SA-106, ASME SA-213, ASTM A335

Eia kekahi, hana pū kā mākou hui i nā paipu kila ʻole no nā hale (GB/T 81628163), nā paipu kila maʻemaʻe no ka haki ʻana o ka ʻaila (GB9948), paipu kila maʻemaʻe no ka mea hoʻomomona kiʻekiʻe (GB6479), paipu paipu aila (API 5L) a me nā paipu pahu aila (API 5CT), a me nā mea hoʻopili paipu huila.
