Cov txheej txheem tsim khoom

Kauv welded yeeb nkab, tseem hu ua SSAW (kauv submerged arc welded) yeeb nkab, yog tsim los siv kauv sib sau thiab submerged arc vuam cov tswv yim.Cov txheej txheem pib nrog kev kho ntug ntawm cov coiled steel sawb thiab tom qab ntawd khoov cov sawb mus rau hauv ib lub voj voog.Tsis siv neeg submerged arc vuam yog siv los koom nrog cov npoo ntawm cov strips ua ke, tsim kom muaj kev sib txuas txuas ntxiv raws qhov ntev ntawm cov yeeb nkab.Txoj kev no ua kom ntseeg tau tias qhov sib koom ua ke muaj zog thiab ruaj khov thaum txo qis qhov tsis xws luag thiab tswj kev ua haujlwm zoo.

Qhov zoo ntawm kauv welded carbon steel yeeb nkab

1. Lub zog thiab kav ntev:Spiral welded carbon steel yeeb nkabpaub txog nws lub zog zoo dua thiab ua haujlwm ntev, ua rau nws haum rau cov ntawv thov uas xav tau kev kub siab ua haujlwm thiab kev ua haujlwm ntev.

2. Kev Ua Tau Zoo: Cov kav dej no muab cov kev daws teeb meem zoo vim tias lawv cov txheej txheem tsim tau zoo, cov khoom siv qis dua, thiab txo cov kev ua haujlwm ntawm cov kav dej piv rau lwm cov kav dej.

3. Versatility: Lub versatility ntawm kauv welded carbon steel yeeb nkab tso cai rau nws siv nyob rau hauv ntau yam kev siv, xws li kev thauj mus los hauv dej, roj thiab roj tsheb thauj mus los, piling structures, dej phwj tuaj, thiab ntau yam kev lag luam.

4. Dimensional raug: Cov txheej txheem muab kauv tuaj yeem tswj tau qhov loj thiab phab ntsa tuab ntawm cov yeeb nkab, kom ntseeg tau qhov raug thiab sib xws ntawm kev tsim khoom.

Cov chaw thov

1. Kev lag luam roj thiab roj av: Kauv welded carbon steel kav yog siv dav hauv kev lag luam roj thiab roj, tshwj xeeb tshaj yog nyob rau hauv kev thauj mus los ntawm cov roj av, roj av thiab cov khoom siv roj av.Lawv lub zog thiab muaj peev xwm tiv taus qhov chaw muaj kev kub ntxhov ua rau lawv zoo tagnrho rau cov kav dej ntev.

2. Kev xa dej: Txawm hais tias yog rau cov dej hauv nroog lossis dej hauv lub hom phiaj, kauv welded carbon steel kav muab kev daws teeb meem zoo heev vim lawv cov corrosion kuj, lub zog thiab yooj yim ntawm installation.

3. Kev them nyiaj yug tus qauv: Hom yeeb nkab no tau siv dav hauv kev tsim kho kev lag luam los muab kev txhawb nqa rau cov tsev, txuas hniav, docks thiab lwm yam kev tsim kho vaj tse.Lawv durability thiab tsis kam rau cov khoom sab nraud ua rau lawv ntseeg tau hauv cov ntawv thov.

4. Kev Siv Hluav Taws Xob: Kauv welded carbon steel kav yog siv nyob rau hauv ntau yam kev lag luam xws li kev ua tshuaj lom neeg, cov chaw tsim hluav taws xob thiab kev ua haujlwm mining vim lawv muaj peev xwm tswj tau qhov kub thiab txias, siab thiab corrosive ib puag ncig.

Hauv kev xaus

Kauv welded carbon steel yeeb nkab, xws liX42 SSAW tub, tau hloov kho cov txheej txheem hlau yeeb nkab vuam, nqa ntau cov txiaj ntsig rau kev lag luam sib txawv.Lawv lub zog, durability, nqi-zoo thiab qhov tseeb qhov tseeb ua kom muaj kev ncaj ncees ntawm ntau yam kev siv.Lub peev xwm tiv taus huab cua kub, kub thiab corrosive ib puag ncig ua rau nws zoo tagnrho rau kev xa cov roj thiab roj, dej thiab lwm yam kev lag luam.Yog li ntawd, thaum nws los txog rau hlau yeeb nkab welding, kev siv cov kauv welded carbon steel kav tseem yog ib tug txhim khu kev qha thiab npaum kev daws teeb meem los xyuas kom meej lub sij hawm ntev thiab resilient infrastructure.

Hydrostatic Test

Txhua qhov ntev ntawm cov yeeb nkab yuav tsum raug kuaj los ntawm cov chaw tsim khoom mus rau lub siab hydrostatic uas yuav tsim nyob rau hauv cov yeeb nkab phab ntsa ib qho kev ntxhov siab tsis pub tsawg tshaj 60% ntawm qhov tsawg kawg nkaus yield zog ntawm chav tsev kub.Lub siab yuav tsum tau txiav txim los ntawm qhov sib npaug hauv qab no:
P = 2st/D

Permissible variations In Weights and Dimensions

Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau ntsuas nyias thiab nws qhov hnyav yuav tsum tsis txhob sib txawv ntau dua 10% tshaj lossis 5.5% raws li nws qhov hnyav, suav nrog nws qhov ntev thiab nws qhov hnyav ntawm ib chav tsev ntev.
Sab nraud txoj kab uas hla yuav tsum tsis txhob sib txawv ntau tshaj ± 1% ntawm lub npe nominal sab nraud txoj kab uas hla
Phab ntsa thickness ntawm txhua qhov chaw yuav tsum tsis pub ntau tshaj 12.5% raws li cov phab ntsa thickness
