ʻO kēia ʻano paipu kila hoʻoheheʻe ʻia e ka mea hoʻololi a i ʻole ke ahi hāmama, ʻo kāna mea waiwai nui he hao i hoʻoheheʻe ʻia a me ke kila ʻōpala, ʻoi aku ka kiʻekiʻe o ka sulfur a me ka phosphorus i ke kila ma mua o ke kiʻekiʻe o ke kiʻekiʻe carbon structural paipu kila, maʻamau sulfur ≤0.050 %, phosphorus ≤0.045%. ʻO ka ʻike o nā mea hoʻohui ʻē aʻe, e like me ka chromium, nickel a me ke keleawe, i lawe ʻia i loko o ke kila e nā mea maka, ʻaʻole ma mua o 0.30%. E like me ka haku mele ʻana a me nā koi hana, hōʻike ʻia ka pae o kēia ʻano paipu kila e ke kila kila Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275 a pēlā aku.

'Ōlelo Aʻo: "Q" ʻo ia ka pīʻāpā phonetic Kina o ka hua "qu", a ukali ʻia e ka helu haʻahaʻa haʻahaʻa (σ S) waiwai o ka papa, a ukali ʻia e ka hōʻailona e like me nā mea haumia (sulfur, phosphorus) maʻiʻo mai ke kiʻekiʻe a haʻahaʻa. me nā hoʻololi i nā mea kalapona a me manganese, i hoʻokaʻawale ʻia i ʻehā mau papa A, B, C, D.

ʻO kēia ʻano ʻano paipu kila kila ka mea nui loa, ākea loa ka hoʻohana ʻana, ʻoi aku ka ʻōwili ʻia i loko o ka pā, profile (poe, square, flat, work, groove, Angle, etc.) and profile and manufacturing welding steel pipe. Hoʻohana nui ʻia i ka hale hana, ke alahaka, ka moku a me nā hale kūkulu hale ʻē aʻe a me nā paipu lawe wai maʻamau. Hoʻohana pololei ʻia kēia ʻano kila me ka mālama ʻole ʻana i ka wela.

Ma waho aʻe o kekahi nui o ka silikoni a i ʻole manganese, aia nā paipu kila i nā mea ʻē aʻe i kūpono i nā kumu waiwai o Kina. E like me ka vanadium (V), niobium (Nb), titanium (Ti), aluminika (Al), molybdenum (Mo), nitrogen (N), a me ka honua laha ʻole (RE). Wahi a ka haku mele a me nā koi hana, ua hōʻike ʻia kona māka e Q295A, B, Q345A, B, C, D, E, Q390A, B, C, D, E, Q420A, B, C, D, E, Q460C, D , E a me nā māka kila ʻē aʻe, a ʻo kona ʻano he like ia me ka paipu kila kila.

Ma waho aʻe o ke kila A a me B, pono e loaʻa i ka kila papa C, GRADE D a me ka Papa E ma ka liʻiliʻi loa o hoʻokahi o nā mea ʻano mea ʻai i hoʻomaʻemaʻe ʻia e like me V, Nb, Ti a me Al. I mea e hoʻomaikaʻi ai i ka hana o ke kila, hiki ke hoʻohui ʻia ke kila kila A, B i kekahi o lākou. Eia kekahi, ʻoi aku ka liʻiliʻi o ke koena o Cr, Ni a me Cu ma mua o 0.30%. ʻO Q345A, B, C, D, E nā māka mākaʻikaʻi o kēia ʻano kila, a ma waena o nā kila kila A, B i kapa ʻia ʻo 16Mn; Pono e hoʻohui ʻia ma mua o hoʻokahi ʻano mea i ka pae C a ma luna o ka paipu kila, a pono e hoʻohui ʻia i hoʻokahi waiwai hopena haʻahaʻa i kona mau waiwai mechanical.

ʻO ka lakio o kēia ʻano paipu kila kila i ke kila kila. Loaʻa iā ia nā pōmaikaʻi o ka ikaika kiʻekiʻe, ka hoʻokō piha maikaʻi, ke ola lawelawe lōʻihi, ka laulā noi ākea a me ka hoʻokele hoʻohālikelike. Hoʻohana nui ʻia ia i nā Bridges, nā moku, nā paila, nā kaʻa a me nā hale hale koʻikoʻi.
