① kūlana o ka lawe ʻana
Hōʻike i ke kūlana o ka hoʻololi ʻana i ka plastik hope a i ʻole ka mālama wela hope o ka huahana i hāʻawi ʻia. ʻO ka maʻamau, ʻo ka ʻōwili wela a i ʻole ka huki anu (rolling) mokuʻāina a i ʻole ka mokuʻāina ʻoihana: ʻoihana wela wela no ka lawe ʻana ma hope o ka mālama ʻana i ka wela, a i ʻole ke ahi maʻamau (maʻamau), ka hoʻoponopono maikaʻi, ka hopena paʻa, ka moku'āina annealing e like me keʻano o ka mālamaʻana i ka wela. Ke kauohaʻia, e hōʻikeʻia ke kūlana hoʻouna i loko o kaʻaelike.
Hāʻawi ʻia ʻo ② e ke kaumaha maoli a i ʻole ke kaumaha kumu
Kaumaha maoli-Ma ka lawe ʻana, hāʻawi ʻia ke kaumaha o ka huahana ma ke kaupaona ʻana (kaumaha) paona;
Kaumaha manaʻo-ʻO ke kaumaha o ka huahana ke kaumaha i helu ʻia mai ka nui inoa o ke kila. ʻO ke ʻano helu helu penei (koi ʻia e like me ke kaumaha theoretical, e hōʻike ʻia i loko o ka ʻaelike): ke kaumaha theoretical i kēlā me kēia mika (ka mānoanoa o ke kila. ʻo 7.85 kg/dms3) ka helu helu:
ʻAno w= (DS) S: ke kaumaha o ka manaʻo o T hoʻokahi paipu kila no ka mika, kg/m;ke anawaena o waho o ka paipu kila D, m: s ka mānoanoa o ka paia o ka paipu kila, m.
③ nā kūlana hōʻoia
E like me ke kūlana o kēia manawa o ka lā i ʻōlelo ʻia o ka nānā ʻana a hōʻoia i ka hoʻokō ʻana o ka maʻamau, i kapa ʻia nā kūlana hōʻoia.
A. Nā kūlana hōʻoia kumu (kahi i ʻike ʻia he kumu hoʻopaʻapaʻa koi). Inā hōʻike ʻia i loko o ka ʻaelike. ʻO nā waiwai, ka ʻokoʻa nui, ka maikaʻi o ka ʻili a me ka ʻike ʻana i nā hemahema, ka hoʻāʻo hydraulic a i ʻole ka peʻahi kaomi a i ʻole ka hoʻonui ʻana 1 1 a me nā hoʻokolohua hana hana ʻē aʻe.
B. Agreement guarantee conditions: Ma waho aʻe o nā kumu kumu hōʻoia i loko o ka maʻamau, aia nā "kūkākūkā ma waena o nā ʻaoʻao ʻelua e like me nā koi o ka mea koi.aiʻole ” ke makemake ka mea kūʻai mai.E ʻimi…, pono e hōʻike ʻia ma ka ʻaelike “;kekahi mau mea kūʻai mai, i ka kumu palapala hoʻokō pono e like me ka haku mele 'ana, mechanical waiwai, ka nui deviation, etc.) ai 'ole nā mea nānā 'ē aʻe (e like me ke kila paipu ellipticity, unequal pā mānoanoa). e kūkākūkā, e kau inoa i ka ʻaelike ʻenehana lako a hōʻike iā ia i loko o ka ʻaelike.
④ kākau i nā ʻōlelo aʻo a i ʻole nā manaʻo ma
ʻO ka "puʻupuʻu" ma ka maʻamau e pili ana i kahi pūʻulu nānā,ʻo ia hoʻi ka pūʻulu nānā. liʻiliʻi, hiki ke hoʻokaʻawale ʻia ka pūʻulu nānā i nā pūʻulu hoʻouna.
A. E haku ʻia kēlā me kēia pūʻulu i nā paipu kila me ka helu hōʻailona like (ke kila), ka helu o ka umu ahi (tank) a i ʻole ka helu umu hoʻokahi makuahine, ka kikoʻī like a me ka ʻōnaehana mālama wela like (nā manawa umu).
B. No ke kiʻekiʻe kiʻekiʻe kalapona kila structural paipu a me ka wai paipu, okoa umu (tanks) hiki ke loaʻa i ka helu momoku ahi like, ka ia kiko'ī a me ka ia wela wela nenoaiu (manawa umu).Huipuia o ka paipu kila.
C. E haku ʻia kēlā me kēia pūʻulu o ka paipu kila i hoʻopaʻa ʻia me ka paipu kila me ka pae like (steel grade) a me nā kikoʻī like.
⑤ kila maikaʻi a me ke kila maikaʻi
Ma GB / T699-1999 a me GB / T3077-1999 mau kūlana, kona hōʻailona hoʻi me "A", no ke kila kila kiʻekiʻe, i ʻole ke kila kila kiʻekiʻe.
A. E ho'ēmi i ka laulā maʻiʻo ʻāpana:
B. E ho'ēmi i ka maʻiʻo o nā mea ʻino (e like me ke kahe, phosphorus a me ke kila):
