Paipu huinahahe ʻano ʻano pahu kila hollow square section shape steel, i ʻike ʻia hoʻi he paipu square,paipu hāhāhā.Hōʻike ʻia kāna kikoʻī ma ka mm o ke anawaena o waho * ka mānoanoa pā.Hana ʻia ia me ke kila ʻōwili wela e ka ʻōwili anu a i ʻole ke kaha kiʻi anu.
Ka hoʻohana ʻana i ka paipu huinahā like ʻole:
huinahā lauwili ʻole apaipu huinahāhā yuantaihoʻohana nui ʻia.Hoʻohana maʻamau ia i ka hana ʻana i nā ʻāpana hana a me nā ʻāpana mechanical, e like me ka ʻaila drill pipe, kaʻa hoʻoili kaʻa, ka paikikala a me ka scaffolding kila i hoʻohana ʻia i ke kūkulu ʻana, i hana ʻia me ke kila kila kila kiʻekiʻe e ka ʻōwili wela a i ʻole ke kiʻi anu, a ua hoʻohana nui ʻia e like me nā paipu a i ʻole nā ʻāpana hana e lawe i nā wai.
Ke ʻano o ka paipu ʻāpana ʻehā ʻole:
1. E like me ka mea, hiki ke hoʻokaʻawale ʻia i ke kila kila maʻamau a me ke kila kila kiʻekiʻe.ʻAʻole ʻoi aku ka nui o ke kalapona ma mua o 4.5%;Sulfur ≤ 0.035;phosphorus ≤ 0.005;chromium ≤ 0.15;maʻiʻo nikela<0.25;keleawe ≤ 0.30;Loaʻa i ka mea hope kahi liʻiliʻi o ka silika, manganese a me ka vanadium me ka carbon, sulfur, phosphorus a me chromium.
2. E like me ka maikaʻi o ka ili:
(1) Hoʻopau:
1 ʻO ka ʻili o loko a me waho o ka paipu huinahalike ʻole e maʻalahi a palahalaha me ka ʻole o nā ʻōhū a me nā wrinkle.
2 Ke emi ka ʻili o loko ma lalo o 100 mm2, ʻo ka ʻae ʻia ʻana o ka ʻili o loko he ± 0.2 mm.
3 Ke ʻoi aku ka nui o ka ʻili o loko ma mua o 100 mm2, ʻo ± 0.5 mm ka ʻae ʻia o ka ʻili o loko.
4 ʻAʻole ʻae ʻia nā māwae a i ʻole nā pelu ma ka ʻili o loko;5 ʻAʻole e ʻulaʻula.
(2) Palahalaha:
1 ʻO ka ʻili o loko a me waho o nā paipu huinahalike ʻole he palahalaha a pahee.
2 ʻAʻole pono ke ʻano like ʻole ke nānā ʻia me kahi aniani hoʻonui 10X.
3 ʻO ka ʻaoʻao hope o ka nozzle ua kū pololei i ke kikowaena o ka paipu.
4 ʻAʻole ʻae ʻia ka ʻaoʻao hope o ka puka paipu me nā ʻū.
5 ʻAʻole ʻumi ʻia ma ka piko o ka paipu.
6 E kulike na welau elua o ka paipu.
7 ʻAʻole ʻae ʻia ka puʻupuʻu ʻike ma ka weld ma hope o ka wehe ʻana i ka ʻōpala.
8 ʻAʻohe lua maopopo.
9 ʻAʻole ʻae ʻia nā hemahema e pili ana i ka hoʻohana.
10 Ke hoʻohana ʻia ka mīkini ʻōwili pā no ka wili, ʻaʻole e emi ka radius fillet ma ka weld ma mua o ka mānoanoa o ka metala kumu.
(3) Ka pololei o ke ana:
1 ʻAʻole ʻoi aku ka hewa o ka pōʻai ma mua o 2 mm/m2 i ʻoi aku ma mua o ka ʻokoʻa kiʻekiʻe i hōʻike ʻia ma ke kūlana kūpono.
2 ʻAʻole ʻoi aku ka pololei a me ka ʻae ʻana o ke kihi ma mua o 1/20 o ka ʻokoʻa kiʻekiʻe i ʻōlelo ʻia ma ke kūlana kūpono.
3 ʻAʻole e ʻoi aku ka palena palena o ka lōʻihi ma mua o 1.5 manawa o ka waiwai i kuhikuhi ʻia.
ʻO ka mana maikaʻi opaipu kila yuantaikoʻikoʻi loa, no laila hiki i nā mea kūʻai ke koho me ka hilinaʻi.Hui YuantaiLoaʻa iā 77 mau palapala patent,kila Yuantaiua lanakila ʻo ia i ka poʻokela hoʻokahi o ka ʻoihana pahu rectangular no 10 mau makahiki,
Inā pono ʻoe e kiʻiyuantai kila paipu kumukuai， E ʻoluʻolu e kelepona mai iā mākou.
