Tus Hlau Yeeb Nkab Ua Li Cas? Cov Ntawv Tseem Ceeb & Variables

Carbon Steel Pipes — **Cov Kav Hlau Hlau**

Raws li tus kws ua haujlwm tsim kho ntawm Huayang Steel yeeb nkab Co., Ltd.hluav taws xob tiv thaiv welded steel yeeb nkabrauHFW Steel Yeeb NkabCov. Nkag siab txog txoj cai ua haujlwm pab kom ntseeg cov ntaub ntawv peb muab, lawv npaj kev txhawb nqa rau high- hfw kav. Hauv tsab xov xwm no, peb yuav tawg cov qauv tseem ceeb, thiab yuav ua li cas Huayang Customator rau phim peb cov pa specifications {}} Thaum lub sij hawm hais meej zoo liERW cov yeeb nkab ntsiab lusthiab HFW lub ntsiab lusrau cov ntsiab lus teb.

Ntawm lub plawv ntawm txhua tus neeg siv hluav taws xob ua haujlwm hnyav yog ib tus qauv tsim los ntawm Carbon Steel lub ntom ntom (7.85 g /} Cov ntaub ntawv peb tsuas yog siv rauhluav taws xob tiv thaiv welded steel yeeb nkabthiabHFW Steel Yeeb NkabCov. Cov qauv ficula rau cov yeeb nkab hollow, tsom mus rau qhov hnyav "ntawm cov hlau (tsis suav nrog qhov chaw sab hauv).

Cov mis uas dav tshaj plaws siv cov mis (thiab ib qho peb cia siab rau ntawm HUAYANG) yog:

Qhov hnyav rau ib meter meter (kg / m)=0.02466 × × × (od {{t)

Qhov twg:

0.02466: A constant derived from carbon steel density (7.85 g/cm³) and unit conversion (converting millimeters to meters and cubic centimeters to kilograms-eliminating the need for clients to handle complex unit math).

T: Phab Ntsa Thickness ntawm cov yeeb nkab (hauv millimeters, mm)-} qhov sib txawv ntawm hom yeeb nkab thiab sijhawm (SCH) qib.

Od: Theter txoj kab uas hla ntawm cov yeeb nkab (hauv millimeters, mm)- Qhov loj me (piv txwv li, nps 4 kav hlau muaj tus qauv OD ntawm 114.3mm).

Cia peb siv qhov no rau peb feem ntauhluav taws xob tiv thaiv welded steel yeeb nkab: Nps 4, Sch 40 (siv hauv nroog hauv nroog). Nws cov lus qhia tshwj xeeb yog t= 6.02 hli, ol=114.3 hli. Plugging rau hauv cov mis:

Qhov hnyav rau ib lub ntsuas ntsuas=0.02466 × 6.02 × (× 0.02466 × 6.28 ≈ 16.8kg / m.

Qhov no phim rau qhov hnyav tiag

Thaum od thiab t yog cov qauv nkag, qee cov neeg siv khoom (piv txwv li, cov neeg hauv kev ua lag luam tshuaj) muab cov taub sab hauv txiav txim siab ua kua muaj peev xwm. Rau cov rooj plaub no, peb siv cov qauv hloov pauv hloov tshiab rau OD (txij li Od {{4} {5} {t):

Qhov hnyav rau ib meter meter (kg / m)=0.02466 × × × t × (id + t)

Qhov no yog tshwj xeeb siv rau pebHFW Steel Yeeb Nkab, uas feem ntau muaj cov phab ntsa thicker rau qhov siab -} qhov kev siv siab. Nqa peb NPS 8, SCH 80 HFW YEEB (siv hauv cov roj sib kis): id {{4= 219.1 hli, t= 10.31 mm). Siv daim ID ID:

Qhov hnyav rau ib lub ntsuas ntsuas=0.02466 × 10.31} ({{2 × 0.02466 ≈ 53.5kg / m.

Qhov no ua kom haum nrog Od - Raws kev xam, kom cov neeg siv khoom siv tsis hais txog txoj kab no lawv muab. Ntawm Huayang, peb lub laij lej online tau hloov ntawm ob tus qauv raws li cov neeg siv khoom siv {}} txuag lawv lub sijhawm thiab txo cov yuam kev.

Qhov ceev yog lub hauv paus ntawm kev suav hnyav, thiab rau peb cov kav dej, peb nruj me ntsis siv 7.85 g / cmÃ (ceev ntawm cov roj carbon hlau). Qhov no tsis yog - sib ceg vim tias:

Hluav taws xob tiv thaiv welded steel yeeb nkabSiv tsawg -} roj carbon steel (0.05% -0.25% c), uas muaj qhov sib txawv ntawm kev tsis huv (peb txwv tsis pub dhau 0.05%, yog li ceev tsis ruaj khov).

HFW Steel Yeeb NkabSiv nruab nrab - @} -0.60 -0.60%, uas tseem muaj lub zog ntau dua tab sis tsis ntom.

Peb ib zaug muaj tus neeg siv yuam kev siv kev siv cov hlau tsis muaj zog siv (7.93 g / cm³) rau peb cov kab mob ERW, ua rau 1% overestate ntawm tag nrho qhov hnyav. Txhawm rau tiv thaiv qhov no, peb lub laij lej siv rau 7.85 g /M³ yog tias: "Rau Huayang cov pa roj carbon hlau erw / hfw} g /}} Tsis muaj kev hloov kho uas xav tau." Peb kuj tsis lees txais txhua tus neeg thov kev thov kom siv lwm yam ntxim nyiam rau peb cov qauv cov qauv, vim tias nws yuav muaj kev sib yeem.

Phab Ntsa Thickness (t) yog qhov kev sib txawv tshaj plaws, raws li nws nyob ntawm cov yeeb nkab lub sijhawm (sch, sch {{}} thicker phab ntsa). Ntawm Huaayang, peb sivnominal ntsa tuab(Tus qauv ntawm tus qauv rau txhua tus qauv lej) hauv kev suav nrog {{}} Ii txawm hais tias yog qhov tseeb thickness muaj qhov tseeb thickness muaj qhov tseeb ntawm ± 10% (ib tus GB / T 3091 rau ERW thiab API 5L rau HFW).

Piv txwv li:

Peb lihluav taws xob tiv thaiv welded steel yeeb nkab(Nps 2, Sch 40) muaj ib qho nominal t ntawm 3.91mm- tiag t ranges los ntawm 3.52mm rau 4.30mm.

Peb liHFW Steel Yeeb Nkab(Nps 10, SCH 120) muaj nominal t ntawm 14.27mm - tiag t ranges los ntawm 12,84mm rau 15.70mm.

Txhawm rau zam kev tsis meej pem, peb lub laij lej siv cov npe nrov t tab sis suav nrog lub 'meter': 5.4kg ± 0.4kg ± 0.4gg ± 0.4kg ± 0.4kg ± 0.4kg ± 0.4kg ± 1 sch 40 ERW YEEB "). Qhov no yog qhov tseem ceeb rau 2024 Beijing lub chaw hauv nroog: Tus neeg siv khoom siv rau phau ntawv tsheb, thiab kev siv nyiaj ntau rau lawv tsis tau ntsib teeb meem cov kav dej ntau dua.

Feem ntau cov zauv laij lej hnyav los laij tawm qhov hnyav ib meter, tab sis cov neeg yuav tsum tau muaj qhov hnyav tag nrho rau kev txiav txim siab rau kev txiav txim siab rau kev txiav txim siab kom ntev (l) yog qhov kawg siab sib txawv. Ntawm Huaayang, peb muab ob tus qauv ntev, uas peb ua ntej -}}}}}}}}}}}}:
