He ʻāpana hakahaka ka paipu paila ma nā wēlau ʻelua, a he ʻāpana hakahaka kona. ʻO ka lōʻihi a me ka puni o ke kila nui, hiki ke hoʻokaʻawale ʻia ke paipu kila seamless a me ke paipu kila welded e like me ke ʻano hana. Hiki ke hoʻokaʻawale ʻia ke paipu kila i nā ana holoʻokoʻa (e like me ke anawaena a i ʻole ka lōʻihi) a me ka mānoanoa o ka paia e like me nā kikoʻī o ka paipu kila. He ākea loa kona nui, mai ke anawaena liʻiliʻi a hiki i kekahi mau mika ke anawaena, mai ke anawaena nui o ka paipu kila.

Hiki ke hoʻohana ʻia nā paipu kila no ka paipu ʻana, nā lako wela, ka ʻoihana mīkini, ka ʻimi ʻana i ka ʻāina petroleum, nā ipu, ka ʻoihana kemika a me nā kumu kūikawā.

(1) Ke kila kila kūkulu kalapona kiʻekiʻe 20G, 20MnG, 25MnG.

(2) Ke kila hoʻonohonoho ʻia me ke kinikini 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, a pēlā aku.

Ua māhele ʻia ka paipu paila i ʻelua mau ʻāpana:GB/T3087-2018paipu paila waena a me ke haʻahaʻa haʻahaʻa,GB/T5310-2018paipu paila kaomi kiʻekiʻe. ʻO kā mākou huahana nui:

ASTMA210(A10M)-2012ʻO ka paila kila kalapona waena a me ka paipu kila seamless superheater, ʻo ka mea nui ʻo SA210 GrA1, SA210GrC;

ASME SA106/SA-106M-2015, ʻo nā mea nui ʻo GR.B gr.C;
