E hoʻopili ʻia ka paipu kila i hana anu ma hope o ka hana ʻana.Inā pono, hiki i ka mea kūʻai ke kuhikuhi i ka mālama wela o nā welds o STPG 410 resistance welded steel pipe.
Inā hoʻohana ʻia ka wili kuʻi, pono e hoʻoneʻe ʻia nā kuʻekuʻe ma ka ʻaoʻao o loko a me waho o ka paipu e loaʻa ai kahi weld maʻemaʻe ma ke ʻano o ka paipu.Eia naʻe, inā paʻakikī ka wehe ʻana i ka weld ma ka ʻili o loko, hiki ke mālama ʻia ke kūlana welded.
Hoʻopaʻa ʻia ʻo Wela - Pipe Keʻokeʻo
No ka meakeʻokeʻopaipu(paipu haawi zinc-coating), ka ili o ka nanapaipu ʻeleʻele(ʻO nā paipu i hāʻawi ʻole ʻia i ka zinc-coating) e hoʻomaʻemaʻe ʻia e ka sandblasting, pickling, a i ʻole nā lāʻau ʻē aʻe ma mua o ka hoʻoheheʻe ʻana i ka wela.ʻO ka Zinc no ka hoʻoheheʻe ʻana i ka wela wela he JIS H 2107 Grade 1 distilled zinc ingot a i ʻole zinc o ka like a ʻoi aku ka maikaʻi.
ʻO nā koi maʻamau ʻē aʻe no ka galvanizing e like me JIS H 8641.

ʻO nā mea maʻamau o nā hoʻokolohua analytical a me nā ʻano o ka laʻana a me ka nānā ʻana e like me ka JIS G 0404 'ikamu 8 (Kemimi hoʻohui).
E like ke kaʻina hana analytical me JIS G 0320.

Na Pono Mechanical o JIS G 3454
ʻO nā koi maʻamau no ka hoʻāʻo mechanical e like me JIS G 0404 Paukū 7 (Nā Manaʻo Nui) a me ka Paukū 9 (Mechanical Properties).
Eia nō naʻe, ʻo ke ʻano o ka hōʻiliʻili ʻana i nā specimen no ka hoʻāʻo ʻana e like me ka JIS G 0404 Paukū 7.6 (Nā kūlana hōʻiliʻili a me nā mea hoʻohālike), Type A.
E hana nā mea hōʻike paipu i nā hoʻokolohua e like me JIS Z 2241 a ʻo ka ikaika tensile, ka hoʻoulu ʻana, a me ka elongation e like me ka Papa 3.
Eia naʻe, no nā paipu i emi iho ma lalo o 8 mm mānoanoa, e like ka elongation me ka Papa 4 no nā ho'āʻo tensile me ka hoʻohana ʻana i ka helu 12 a i ʻole No. 5 specimens.
Ho'āʻo palahalaha
ʻO ka mahana ho'āʻo he lumi lumi (5 ~ 35 ℃), kau ʻia ka specimen ma waena o ʻelua mau papa pālahalaha a hoʻopaʻa ʻia a hiki i ka mamao o ka H ma waena o nā papa ma lalo o ka waiwai i ʻōlelo ʻia, ke hoʻopalapala ʻia ka specimen, e nānā inā he māwae. ma ka ili o ka paipu kila.
Ke H=2/3D, e nānā i ka weld no nā māwae.
Ke H=1/3D, e nānā i nā māwae ma nā ʻāpana ʻē aʻe ma waho o ka hili weld.
Hiki ke hoʻokuʻu ʻia ka paipu kila ʻole mai ka hoʻāʻo palahalaha, akā pono ka hana o ka paipu e like me nā ʻōlelo.
Ho'āʻo Kulou
Pili i nā paipu me ka anawaena o waho ≤ 40A (48.6mm).
ʻAʻole e māhā ka mea hoʻohālike i ka wā e pio ai ma 90° me ka radius o loko o 6 manawa o ke anawaena o waho.
Hiki i ka mea kūʻai ke kuhikuhi i kahi kihi piko o 180 a / a i ʻole radius i loko o 4 mau manawa o ke anawaena o waho o ka paipu.
No nā paipu welded kū'ē, e loaʻa ka wili weld ma kahi o 90° mai ka ʻaoʻao loa o ka piko.
ʻO ka hoʻāʻo hydraulic a i ʻole ka hoʻāʻo hoʻopau ʻole
Pono nā paipu a pau e ho'āʻo hydraulically a i ʻole hoʻāʻo ʻole ʻia.
Eia naʻe, no nā paipu keʻokeʻo, hana maʻamau kēia ma mua o ka galvanizing.
ʻO ka hydrotesting a i ʻole ka hoʻāʻo ʻole luku ʻia he ala nui o ka mālama ʻana i ka maikaʻi o ka paipu e hōʻoia i ka palekana a me ka hilinaʻi o ka paipu i ka wā e hoʻokomo ai a hoʻohana.
Hoʻāʻo Hydrostatic
E noi i kahi kaomi ho'āʻo hydraulic kiʻekiʻe aʻe ma mua o ka kikoʻī i ka paipu a paʻa iā ia no ka liʻiliʻi he 5 kekona e ʻike inā hiki i ka paipu ke kū i ke kaomi a inā hiki mai ka leakage.
