Q345B ka palapala hoʻokō o ka mea hana paipu kila
I loko o ka moʻo paipu kila maʻemaʻe, aia kahi mea i kapa ʻia ʻo Q345B seamless steel pipe, nona ka moʻo haʻahaʻa haʻahaʻa. Ma waena o nā mea haʻahaʻa haʻahaʻa, ʻo kēia mea ka mea maʻamau. Q345B paipu kila maʻemaʻe i kapa ʻia ʻo 16Mn paipu kila ʻole. Nui nā ʻano hoʻokaʻawale. E like me ke kaʻina hana, aia nā: hot rolled seamless paipu a me anu. E like me ke kumu, aia nā: paipu kila maʻemaʻe no ka hana maʻamau, paipu kila maʻemaʻe no ka hoʻouna ʻana i ka wai, paipu kila maʻemaʻe no ka paila haʻahaʻa haʻahaʻa a me ka paipu kila maʻemaʻe no ka paila kiʻekiʻe. E like me ka mea, aia nā: kiʻekiʻe carbon structural kila seamless kila paipu, haʻahaʻa-alloy structural kila seamless kila paipu a me ka hao kila seamless kila paipu. Hoʻohana nui ʻia ka paipu kila Seamless, hiki ke hana ʻia i loko o nā ʻāpana mechanical, hoʻohana ʻia no ka lawe ʻana i ka wai a i ʻole ke kinoea, hoʻohana ʻia e like me nā bearings, a hoʻohana ʻia e kūkulu i nā hale paʻa.
ʻO ke kūlana hoʻokō waho o Q345B paipu kila ʻole he gb709 a ʻo ke kūlana hoʻokō kūloko ʻo GB / t1591-94.
Ua like ke ano o ka inoa me Q345B.
Ma muli o ka hoʻokō ʻana i ka maʻamau, ʻae ʻia kēia ʻano pā kila e hāʻawi ʻia me ka hoʻomanawanui maikaʻi ʻole.
Q345 seamless kila paipu mea he 'ano o ke kila paipu mea. Hōʻike ka Q i ka hua o kēia mea. ʻO kēia ka 345 e pili ana i ka waiwai o kēia mea, ma kahi o 345. E emi ana ka waiwai me ka piʻi ʻana o ka mānoanoa.
Q345A, ʻaʻohe hopena;
Q345B, 20 ° ka hopena wela maʻamau;
Q345C, 0 degere ka hopena;
Q345D, he - 20 degere ka hopena;
ʻO Q345E - 40 degere ka hopena.
Ma nā wela hopena like ʻole, ʻokoʻa nā koina hopena.
Q345A, Q345B, Q345C, Q345D, Q345E, ʻO kēia ka ʻokoʻa o nā māka, e hōʻike nui ana he ʻokoʻa ka hopena hopena.
ʻO Q345B paipu kila maʻemaʻe he ʻano mea kila, hiki ke māhele ʻia i Q345A, Q345B, Q345C, Q345D a me Q345E e like me ka papa. ʻO ka mea a lākou e hōʻike nei he ʻokoʻa ka wela hopena. Q345A, ʻaʻohe hopena; Q345B, 20 ° ka hopena wela maʻamau; Q345C, 0 degere ka hopena; Q345D, he - 20 degere ka hopena; ʻO Q345E - 40 degere ka hopena.
Hoʻokaʻawale ʻia e ke kaʻina hana: ʻo ka paipu wela ʻole a me ke anu.
E like me ka hoʻohana ʻana, aia nā: paipu kila maʻemaʻe no ka hana maʻamau, paipu kila maʻemaʻe no ka hoʻouna ʻana i ka wai, paipu kila maʻemaʻe no ka paila haʻahaʻa haʻahaʻa a me ka paipu kila maʻemaʻe no ka paila kiʻekiʻe.
Ma ka mea: high quality carbon structural steel seamless steel pipe, haʻahaʻa structural structural steel seamless steel pipe, alloy steel seamless steel pipe.
1. ʻO ka paipu hoʻoheheʻe ʻole ʻia (GB / t8162-2018) he paipu kila maʻemaʻe no ka hana maʻamau a me ka hoʻolālā mechanical.
2. ʻO ka paipu kila maʻemaʻe ʻole no ka lawe ʻana i ka wai (GB / t8163-2018) he paipu kila maʻamau i hoʻohana ʻia no ka lawe ʻana i ka wai, ka aila, ke kinoea a me nā wai ʻē aʻe.
3. ʻO ka paipu kila maʻemaʻe no ka paila haʻahaʻa a me ka haʻahaʻa haʻahaʻa (gb3087-2018) he kiʻekiʻe kiʻekiʻe o ka carbon structural steel hot-rolled a me ke anu i huki ʻia (rolled) seamless steel pipe i hoʻohana ʻia no ka hana ʻana i ka paipu mahu superheated, ka paipu wai paila no ka paila haʻahaʻa a me waena. , paipu mahu pumehana a me ka paipu pōhaku lepo no ka paila locomotive.
4. ʻO ka paipu kila maʻemaʻe no ka paila puʻupuʻu kiʻekiʻe (gb5310-2018) he kila kalapona kiʻekiʻe, ke kila kila a me ke kila wela hoʻopaʻa ʻole ʻia i hoʻohana ʻia no ka hana ʻana i ka ʻili hoʻomehana o ka paila wai me ke kaomi kiʻekiʻe a ma luna.
