Ma ke kahua opaipu kila, he mea ko'iko'i nā kūlana no nā paipu kila wili pololei.ʻO kekahi o nā maʻamau ʻo GB/T3091-2008, e uhi ana i nā ʻano like ʻole o nā paipu kila humuhumu pololei, e like me ke kūpaʻa kiʻekiʻe.paipu kila welded (RW)., powa pohōpaipu kila welded (SAWL).a me nā paipu kila i hoʻopaʻa ʻia i loko o ka wai i hoʻopaʻa ʻia (SAWH).) Paipu kila.
No ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa, ʻōlelo pū ʻo GB/T3091-2008 i ka hoʻohana ʻana onā paipu kila welded galvanized.Hoʻohana ʻia kēia mau paipu kila welded uila, i ʻike nui ʻia ʻo nā paipu keʻokeʻo, e lawe i ka wai, gas, ea, aila, mahu hoʻomehana, wai mahana, a me nā mea ʻē aʻe. ka mānoanoa e like me nā lula o GB/T21835.Eia kekahi, hiki i ka lōʻihi o ka paipu kila mai 300mm a 1200mm, a hiki ke hoʻopaʻa ʻia ka lōʻihi a i ʻole ka lōʻihi pālua.
I ka wā e pili ana i nā pilikia maikaʻi, nui ka hopena o ka mahana i ka wā o ke kaʻina hana.Hiki i nā paipu kila ho'onui wela ke ho'ēmi iki i ka mahana ma kahi o 1200°C, akā na'e, hiki ke ho'emi iki ka ma'i kalapona a me nā mea ho'ohuihui.ʻO kekahi mea nui e noʻonoʻo ai ʻo ka hoʻemi ʻana i ka nui o ka unahi i ka wā o ka piko wela, no ka mea hiki ke hoʻopilikia i ke ola mea hana a me ka maikaʻi o ka ʻili.
He hana koʻikoʻi ka hana ʻana o ka hoʻomehana ʻana i ka hana16Mn paipu kila humuhumu pololei.No ka mea, ʻo ka hapa nui o ka hana ʻana i kahi kūlana wela, ʻo ka hoʻomalu pololei ʻana i ka wela wela he mea koʻikoʻi e hōʻoia i ka maikaʻi o ka huahana hope.
No ka mālama ʻana i ka maikaʻi a me nā kūlana, he mea koʻikoʻi ka hoʻomalu ʻana i ka mahana i ka wā o ka hana ʻana.ʻO ka maʻamau o GB/T3091-2008 ka paipu kila hili pololei i ʻae ʻia i ka nui, ke ʻano, ke kaumaha a me ke anawaena o waho a me ka mānoanoa o ka pā.ʻO ka ʻae ʻia ʻana o ka mānoanoa o ka pā maʻamau e like me ka deviation grade, mai S1 a i S5, a ʻo kēlā me kēia papa e kuhikuhi i ka pākēneka kūpono a me ka haʻahaʻa haʻahaʻa.
Ma waho aʻe o ka mānoanoa pā maʻamau tolerances, non-standardized pā mānoanoa tolerances no hoi noonoo.Loaʻa i nā pae haʻahaʻa (e laʻa me NS1 a i NS4) nā pākēneka kikoʻī e hōʻoia i ka mana maikaʻi.Pono e hoʻomaopopo ʻia ʻo S ka mānoanoa o ka paia o ka paipu kila, a ʻo D ke anawaena o waho o ka paipu kila.
ʻO ka hōʻoia ʻana i ka hoʻokō ʻana i kēia mau maʻamau he mea koʻikoʻi ia i ka hana ʻana i nā paipu puʻu kila longitudinal submerged arc welded steel pile.Ma ka mālama ʻana i ka mana kūpono o ka mahana a me ka nānā ʻana i nā deviations ʻae ʻia, hiki i nā mea hana ke hoʻokō i nā manaʻolana o ka mea kūʻai aku a hāʻawi i nā huahana hilinaʻi a paʻa.
