Ibanga eliyinhloko lepayipi lensimbi

Q345, 15CrMo, 12Cr1MoV, A53A, A53B, SA53A, SA53B

Usayizi weshubhu lensimbi engenamthungo kanye nokuchezuka okuvumelekile

Izinga lokuchezuka Ukuchezuka okuvunyelwe kobubanzi obujwayelekile obungaphandle
D1 ±1.5%,最小±0.75 mm
D2 Kuhlanganisa noma susa u-1.0%. Okungenani +/ – 0.50 mm
D3 Kuhlanganisa noma susa u-1.0%. Okungenani +/ – 0.50 mm

I-Carbon steel tube (I-GB/8162-2008)

Lolu hlobo lwepayipi lensimbi lesakhiwo ngokuvamile lincibilika ngesiguquli noma iziko elivulekile, impahla yalo eluhlaza okuyinhloko yinsimbi encibilikisiwe kanye nensimbi eyizinsimbi, okuqukethwe kwesulfure ne-phosphorus ensimbi kuphakeme kunokwekhwalithi ephezulu yepayipi lensimbi ye-carbon structural, ngokuvamile isulfure ≤0.050 %, i-phosphorus ≤0.045%. Okuqukethwe kwezinye izakhi ze-alloying, njenge-chromium, i-nickel nethusi, okulethwe ensimbi ngezinto zokusetshenziswa ngokuvamile akukho ngaphezu kuka-0.30%. Ngokwezidingo zokwakheka nokusebenza, izinga lalolu hlobo lwepayipi lensimbi lesakhiwo liboniswa ngensimbi yensimbi Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275 njalonjalo.

Qaphela: “Q” iqoqo lezinhlamvu zefonethiki zesiShayina zesivuno “qu”, lilandelwa inani elincane lephoyinti lesivuno (σ S) lebanga, lilandelwa uphawu ngokuya ngezakhi zokungcola (sulphur, phosphorus) ukusuka phezulu ukuya phansi. nezinguquko ku-carbon nezakhi ze-manganese, ezihlukaniswe ngamabanga amane A, B, C, D.

Lolu hlobo lokukhishwa kwepayipi lensimbi lwesakhiwo lukhulu kakhulu, ukusetshenziswa kubanzi kakhulu, kugoqeke kakhulu kupuleti, iphrofayili (eyindilinga, isikwele, isicaba, umsebenzi, umsele, i-Angle, njll.) kanye nephrofayili nokukhiqiza ipayipi lensimbi yokushisela. Isetshenziswa kakhulu ku-workshop, ibhuloho, umkhumbi nezinye izakhiwo kanye namapayipi okuthutha amanzi ajwayelekile. Lolu hlobo lwensimbi ngokuvamile lusetshenziswa ngokuqondile ngaphandle kokwelashwa kokushisa.

I-alloy ephansi enamandla aphezulu ipayipi lensimbi yesakhiwo (I-GB/T8162-2008)

Ngaphezu kwenani elithile le-silicon noma i-manganese, amapayipi ensimbi aqukethe ezinye izakhi ezifanele izinsiza zaseChina. Njenge-vanadium (V), i-niobium (Nb), i-titanium (Ti), i-aluminium (Al), i-molybdenum (Mo), i-nitrogen (N), kanye nezakhi zokulandelela zomhlaba ezingavamile (RE). Ngokwezidingo zokwakheka kwamakhemikhali nokusebenza, ibanga layo limelwe yi-Q295A, B, Q345A, B, C, D, E, Q390A, B, C, D, E, Q420A, B, C, D, E, Q460C, D , E kanye namanye amamaki ensimbi, futhi incazelo yawo iyafana nepayipi lensimbi yesakhiwo se-carbon.

Ngaphezu kwensimbi yebanga A no-B, insimbi yezinga C, GRADE D kanye neBanga E kufanele iqukathe okungenani izakhi zokulandelela okusanhlamvu ezicolisisiwe njenge-V, Nb, Ti kanye ne-Al. Ukuze kuthuthukiswe ukusebenza kwensimbi, insimbi ye-A, B grade nayo ingangezwa kwenye yazo. Ngaphezu kwalokho, okuqukethwe okusele kwe-Cr, Ni ne-Cu kungaphansi kuka-0.30%. I-Q345A, B, C, D, E amamaki amele lolu hlobo lwensimbi, phakathi kwawo A, B grade steel ngokuvamile abizwa ngokuthi 16Mn; Kufanele kwengezwe i-trace element engaphezu kweyodwa ebangeni C nangaphezulu kwepayipi lensimbi, futhi indawo eyodwa enethonya eliphansi lokushisa kufanele yengezwe ezintweni zayo zokuzilungisa.

Isilinganiso salolu hlobo lwepayipi yensimbi yesakhiwo nensimbi yesakhiwo se-carbon. Inezinzuzo zamandla aphezulu, ukusebenza kahle okuphelele, impilo ende yesevisi, ububanzi bohlelo lokusebenza kanye nomnotho wokuqhathanisa. Isetshenziswa kabanzi kumabhuloho, imikhumbi, ama-boilers, izimoto kanye nezakhiwo ezibalulekile zokwakha.
