(1) Ke ano hoohehee kila
E hoʻoheheʻe ʻia ke kila GB 5310 20MnG e ka umu uila me ka hoʻomaʻemaʻe ʻana i ka umu ahi, ka mea hoʻololi oxygen me ka hoʻomaʻemaʻe ʻana i ka umu a i ʻole ke ʻano hoʻoheheʻe electroslag.

(2) Nā ʻano hana a me nā koi no nā blank tube
Hiki ke hana ʻia ka paipu blank ma ka hoʻolei mau ʻana, ka hoʻolei make a i ʻole ka ʻōwili wela (forging).

(3) Keʻano hana o ka paipu kila
E hana ʻia nā paipu kila GB 5310 20MnG e ka ʻōwili wela (extrusion, hoʻonui) a i ʻole kiʻi anu (rolling).

Hoʻohana nui ʻia ia e hana i ke kila kila kila kiʻekiʻe, ke kila huila a me ke kila pale ʻana i ka wela me nā paipu kila ʻole no ke kaomi kiʻekiʻe a ma luna o nā paipu paila mahu.

Hoʻohana nui ʻia no ka lawelawe kiʻekiʻe a me ka wela wela o ka paila (Superheater Tube, Reheater Tube, Air Guide Tube, Main Steam Tube No High and Ultra High Pressure Boilers).Ma lalo o ka hana o ke kiʻekiʻe wela Flue Gas a me ka wai mahu, ka Tube E Oxidize a Corrode.Ua koi 'ia i ka paipu kila he kiʻekiʻe ka lōʻihi, ke kūpaʻa kiʻekiʻe i ka oxidation a me ka corrosion, a me ke kūpaʻa maikaʻi.

Papa o ke kila kila kila kiʻekiʻe: 20g, 20mng, 25mng

Ka lōʻihi:
ʻO ka lōʻihi maʻamau o nā paipu kila he 4 000 Mm ~ 12 000 Mm.Ma hope o ke kūkākūkā ʻana ma waena o ka mea kūʻai aku a me ka mea kūʻai aku, a hoʻopiha i ka ʻaelike, hiki ke hāʻawi ʻia i nā paipu kila me ka lōʻihi ma mua o 12 000 mm a i ʻole pōkole ma mua o 000 mm akā ʻaʻole pōkole ma mua o 3 000 mm;Ka Loihi Pokole Ka heluna o na paipu kila ma lalo o 4,000 mm aka, aole emi malalo o 3,000 mm, aole e oi aku i ka 5% o ka huina o na paipu kila i haawiia.

Kaumaha hoʻouna:
Ke hāʻawi ʻia ka paipu kila e like me ke anawaena o waho a me ka mānoanoa o ka pā inoa a i ʻole ke anawaena o loko a me ka mānoanoa o ka pā inoa, e hāʻawi ʻia ka paipu kila e like me ke kaumaha maoli.Hiki ke hāʻawi ʻia e like me ke kaupaona ʻana.
Ke hāʻawiʻia ka paipu kila e like me ka inoa o waho anawaena a me ka liʻiliʻi o ka mānoanoa o ka pā, e hāʻawiʻia ka paipu kila e like me ke kaumaha maoli;Kūkākūkā nā ʻaoʻao hoʻolako a koi.A ua hoikeia ma ka aelike.Hiki ke hā'awi 'ia ka paipu kila e like me ke kaumaha o ka mana'o.

Kaumaha kaumaha:
E like me nā koi a ka mea kūʻai aku, ma hope o ke kūkākūkā ʻana ma waena o ka mea kūʻai aku a me ka mea kūʻai aku, a ma ka ʻaelike, ʻo ka ʻokoʻa ma waena o ke kaumaha maoli a me ke kaumaha kumu o ka paipu kila hāʻawi ʻia e hālāwai me kēia mau koi:
A) Paipu kila hoʻokahi: ± 10%;
B) ʻO kēlā me kēia pūʻulu o nā paipu kila me ka nui liʻiliʻi o 10 T: ± 7.5%.

Hōʻike Hydraustatic:
Pono e ho'āʻoʻia ka paipu kila me ka hydraulic hoʻokahi.ʻO 20 MPa ka piʻi kiʻekiʻe loa.Ma lalo o ke kaomi ho'āʻo, ʻaʻole i emi iho ka manawa hoʻokūpaʻa ma mua o 10 S, a ʻaʻole pono e kahe ka paipu kila.
Ma hope o ka ʻae ʻana o ka mea hoʻohana, hiki ke hoʻololi ʻia ka Hydraulic Test e ka Eddy Current Testing or Magnetic Flux Leakage Testing.

ʻO ka hoʻāʻo ʻino ʻole:
ʻO nā paipu e koi ana i ka nānā hou aʻe e pono ke nānā ʻia me ka Ultrasonically.Ma hope o ke kūkākūkā ʻana e koi ʻia ka ʻae ʻana o ka ʻaoʻao a ua kuhikuhi ʻia i loko o ka ʻaelike, hiki ke hoʻohui ʻia nā hoʻāʻo hoʻopōʻino ʻole.

Ho'āʻo palahalaha:
ʻO nā paipu me ka anawaena waho i ʻoi aku ma mua o 22 mm e hoʻāʻo ʻia i ka hoʻāʻo ʻana.ʻAʻole ʻike ʻia ka Delamination, nā kiko keʻokeʻo, a i ʻole nā ​​​​mea haumia i ka wā o ka hoʻokolohua holoʻokoʻa.

ʻO ka hoʻāʻo ʻana i ke ahi:
E like me nā koi o ka mea kūʻai aku a i ʻōlelo ʻia i loko o ka ʻaelike, hiki ke hana ʻia ka paipu kila me ka anawaena o waho ≤76mm a me ka mānoanoa o ka pā ≤8mm.Hana ʻia ka hoʻokolohua ma ka wela lumi me kahi lipi o 60 °.Ma hope o ka puhi ʻana, pono e hoʻokō ka wikiwiki o ka puhi ʻana o ka anawaena waho i nā koi o ka papa ma lalo nei, a ʻaʻole pono ka mea hoʻāʻo e hōʻike i nā māwae a i ʻole nā ​​​​haehae.
