SSAW Yeeb Nkab API Spec 5L (PSL2) Rau Cov Yeeb Nkab Roj Ntuj
Ntawm Cangzhou Spiral Steel Pipes Group Co., Ltd., peb zoo siab heev los nthuav qhia peb qhov kev tshawb pom tshiab tshaj plaws hauv kev lag luam yeeb nkab hlau -SSAW yeeb nkabCov khoom tshiab no muab cov thev naus laus zis tshiab nrog kev txawj ntse tsis muaj qhov sib piv los muab cov kev daws teeb meem zoo rau ntau yam kev siv.
SSAW yeeb nkab yog ib qhokauv welded yeeb nkabua los ntawm cov hlau zoo. Peb siv cov thev naus laus zis extrusion siab heev los xyuas kom meej tias qhov kub sib xws thoob plaws hauv cov txheej txheem ntau lawm, thiab tom qab ntawd ua qhov kev vuam ob-xaim ob sab submerged arc tsis siv neeg. Cov thev naus laus zis no ua kom ntseeg tau tias muaj kev sib txuas ruaj khov thiab ruaj khov, ua rau cov yeeb nkab muaj zog thiab txhim khu kev qha.

Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawmkauv welded rajyog nws lub zog zoo dua, uas tshaj qhov ncaj seam welded yeeb nkab. Qhov no ua rau nws zoo tagnrho rau cov haujlwm uas xav tau kev txhim kho kev ruaj khov. Tsis tas li ntawd, vim nws cov txheej txheem tsim khoom tshwj xeeb, cov yeeb nkab welded kauv tuaj yeem tsim los ntawm kev siv cov hlau billets nqaim dua, tso cai rau kev tsim cov yeeb nkab loj dua. Tsis tas li ntawd, los ntawm kev siv cov blanks ntawm tib qhov dav, peb tuaj yeem yooj yim tsim cov yeeb nkab ntawm ntau txoj kab uas hla, ntxiv nthuav nws qhov kev hloov pauv.
Nrog kev cog lus ruaj khov rau qhov zoo, peb lub tuam txhab tau nqis peev ntau yam khoom siv los tsim cov chaw tsim khoom zoo tshaj plaws. Lub tuam txhab npog thaj tsam ntawm 350,000 square meters thiab muaj tag nrho cov cuab tam ntawm 680 lab yuan. Tab sis qhov tseeb ua rau peb sib txawv yog peb pab neeg mob siab rau. Peb cov neeg ua haujlwm ntawm 680 tus kws tshaj lij yog lub zog tsav tsheb tom qab peb txoj kev vam meej.
Peb txaus siab rau peb lub peev xwm tsim khoom txhua xyoo ntawm 400,000 tons ntawm cov yeeb nkab hlau sib ntswg, uas dhau cov qauv kev lag luam. Cov khoom tsim tawm tsis muaj qhov sib xws no tau tsim cov nqi tsim tawm siab heev ntawm 1.8 billion yuan. Peb pab neeg ua haujlwm mob siab xyuas kom meej tias txhua lub cuab yeej tawm hauv peb lub chaw ua raws li cov kev tswj hwm zoo tshaj plaws, lav peb cov neeg siv khoom zoo tshaj plaws.
Hauv kev xaus lus, cov kav dej vuam uas muab kauv rau hauv qab dej yog qhov hloov pauv loj rau kev lag luam yeeb nkab hlau. Nrog nws lub zog zoo tshaj plaws, kev hloov pauv tau zoo heev thiab kev ntseeg siab tsis muaj qhov kawg, nws yog qhov kev daws teeb meem zoo tshaj plaws rau txhua yam koj xav tau ntawm cov yeeb nkab vuam. Koom tes nrog Cangzhou Spiral Steel Pipes Group Co., Ltd. hnub no kom paub txog yav tom ntej ntawm kev lag luam yeeb nkab hlau.
