Kiekie Kiekie Welded Steel Paipu

ʻO ka blank i hoʻohana ʻia no ka paipu kila welded ʻo ia ka pā kila a i ʻole ke kila kila.Ma muli o nā kaʻina hana hoʻoheheʻe ʻokoʻa, ua māhele ʻia i loko o ka umu ahi welded paipu, ka uila kuʻi (kū'ē kū'ē) paipu a me ka arc welded paipu.Ma muli o ko lākou mau ʻano wiliwili like ʻole, ua māhele ʻia lākou i ka paipu wili wili pololei a me ka paipu wiliwili spiral.Ma muli o kona ʻano hopena, ua hoʻokaʻawale ʻia i ka paipu welded circular a me ke ʻano kūikawā (square, flat, etc.) welded pipe.Hoʻokaʻawale ʻia nā paipu welded i nā ʻano like ʻole ma muli o kā lākou mau mea like ʻole a me ka hoʻohana ʻana:
GB / t3091-2008 (welded steel pipe no ka haʻahaʻa haʻahaʻa haʻahaʻa kaʻa wai): hoʻohana nui ia no ka lawe ʻana i ka wai, ke kinoea, ka ea, ka aila, ka wai wela a i ʻole ka mahu a me nā wai haʻahaʻa haʻahaʻa haʻahaʻa a me nā paipu no nā kumu ʻē aʻe.ʻO kāna mea kikoʻī he Q235 grade a kila.
GB / t14291-2006 (welded steel pipe no ka lawe ʻana i ka wai wai): hoʻohana nui ʻia ia no ka paipu kila wili wili pololei no koʻu ea kaomi, hoʻoheheʻe a me ka hoʻoheheʻe kinoea.ʻO ke kila kila Q235A a me B ka mea hōʻike.
GB / t12770-2002 (stainless steel welded steel pipe for mechanical structure): hoʻohana nui ʻia no ka mīkini, kaʻa, kaʻa, nā lako, hōkele a me nā hale ʻaina a me nā ʻāpana mechanical a me nā ʻāpana hana.ʻO nā mea ʻelele he 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0cr18ni11nb, etc.
GB / t12771-1991 (Sila welded steel paipu no ka lawe ʻana i ka wai): hoʻohana nui ʻia ia e lawe i ka media corrosive haʻahaʻa.ʻO nā mea kikoʻī he 0Cr13, 0Cr19Ni9, 00cr19ni11, 00Cr17, 0cr18ni11nb, 0017cr17ni14mo2, etc.
Eia hou, welded kuhiliʻole kila paipu no ka hoʻonani (GB / T 18705-2002), welded kuhiliʻole kila paipu no ka hale hoʻonani (JG / T 3030-1995), a welded kila paipu no ka wela exchangers (yb4103-2000).Loaʻa i ka paipu welded longitudinal nā mea maikaʻi o ke kaʻina hana maʻalahi, ka hana kiʻekiʻe o ka hana, ka haʻahaʻa haʻahaʻa a me ka hoʻomohala wikiwiki.ʻOi aku ka ikaika o ka paipu wiliwili spiral ma mua o ka paipu wili pololei.Hiki iā ia ke hana i ka paipu welded me ka nui o ka paipu anawaena me ka haiki hakahaka, a welded paipu me ka like ole anawaena paipu me ka blank o ka laula like.Eia nō naʻe, ke hoʻohālikelike ʻia me ka paipu seam pololei me ka lōʻihi like, piʻi ka lōʻihi weld e 30 ~ 100%, a haʻahaʻa ka wikiwiki o ka hana.Uncoiling nā mea maka - pae - hoʻopau ʻāhi a me ka hoʻopaʻa ʻana - looper - hoʻokumu - Welding - wehe i loko a me waho weld bead - pre correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydraulic inspection - Pickling - hope inspection (koʻikoʻi mana) - Packaging - hoʻouna.Hoʻohana nui ʻia nā huahana i ka ʻenekinia wai wai, ʻoihana petrochemical, ʻoihana kemika, ʻoihana mana uila, ʻoihana mahiʻai a me ke kūkulu kūlanakauhale.ʻO ia kekahi o nā huahana nui 20 i kūkulu ʻia ma Kina.
