ʻO ka Paipu Kila ʻŌwili S235 J0 - Hana Maikaʻi Loa o ka Paipu Welded Diameter Nui Kiʻi i Hōʻike ʻia

Wehewehe Pōkole:

Kuhi kēia ʻāpana o kēia Kūlana ʻEulopa i nā kūlana hoʻouna loea no nā ʻāpana kūkulu i hoʻopaʻa ʻia i hoʻopili anu ʻia, nā ʻāpana hakahaka o nā ʻano poepoe, huinahā a ʻehā paha a pili i nā ʻāpana hakahaka kūkulu i hana anu ʻia me ka ʻole o ka mālama wela ma hope.

Hoʻolako ʻo Cangzhou Spiral Steel Pipes Group Co., Ltd i nā paipu kila ʻāpana hakahaka o nā ʻano poepoe no ke kūkulu ʻana.

Haʻaheo mākou e hoʻolauna i kā mākou huahana kiʻekiʻe loa,Paipu kila ʻōwili S235 J0, i hoʻolālā ʻia e hoʻokō i nā pono e ulu nei o nā ʻoihana like ʻole. Ma ke ʻano he mea hana alakaʻi i ke kahua, hoʻohana mākou i ka ʻenehana holomua a me ka ʻike loea e hana i ke kūlana kiʻekiʻepaipu laina me ke kūpaʻa a me ka hana kūikawā.

Hana ʻia kā mākou mau paipu kila wili mai nā wili kila ʻāpana ma o ke kaʻina hana kuʻi arc submerged pālua ʻelua ʻaoʻao. Ma o ka ʻenehana hoʻoheheʻe extrusion mahana mau, hōʻoia mākou e hana ʻia kēlā me kēia paipu me ka pololei a me ke kūlike kiʻekiʻe loa. Hōʻoia kēia kaʻina hana hana akahele e hoʻokō kā mākou huahana i nā kūlana kiʻekiʻe loa, e kūpono ai no nā ʻano hana like ʻole.

Ke hoʻohālikelike ʻia me nā paipu welded kuʻuna,Paipu kila ʻōwili S235 J0 he mau hiʻohiʻona koʻikoʻi kēia:

A. I ke kaʻina hana ʻana, hoʻololi like ka papa kila a he liʻiliʻi ke koʻikoʻi koena. ʻAʻole wale kēia e hoʻolōʻihi i ke ola o ka paipu, hōʻoia pū kekahi i ka laumania o ka ʻili o ka paipu a ʻaʻohe ona ʻōpala a kīnā paha.

b. ʻO kā mākou kaʻina hana hoʻoheheʻe arc ʻelua ʻaoʻao holomua e hiki ai ke hoʻoheheʻe pololei i ke kūlana maikaʻi loa. Hoʻemi nui kēia i ka hanana o nā hemahema e like me nā kihi i kūlike ʻole, nā ʻokoʻa hoʻoheheʻe, a me ka hoʻoheheʻe piha ʻole. ʻO ka hopena, he maikaʻi loa ka maikaʻi o ka hoʻoheheʻe ʻana o kā mākou mau paipu, maʻalahi ke kaohi a hōʻoia i ka hana maikaʻi loa.

C. ʻO ka maikaʻi kā mākou mea nui loa. No laila, hana mākou i ka nānā pono ʻana i ka maikaʻi 100% ma kēlā me kēia paipu kila a mākou e hana ai. Hōʻoia kēia nānā piha e hoʻokō kā mākou mau paipu i nā kūlana ʻoihana kiʻekiʻe loa, e hāʻawi ana iā ʻoe i ka maluhia o ka noʻonoʻo ma ke kaʻina hana a me ka hoʻohana ʻana.
