ERW (hluav taws xob tiv thaiv welded) kavyog tsim los ntawm kub dov coils los ntawm hluav taws xob koom nrog ob qhov kawg ntawm lub kauj. High-zaus tam sim no yog dhau los ntawm cov coils siv cov hluav taws xob tooj liab.
Kev tawm tsam hluav taws xob ntws ntawm cov neeg saib xyuas ua rau muaj cua sov kom zoo siab rau cov npoo, tsim kev tawm tsam. Thaum muaj qee qhov kub tau mus txog, nias tau thov, ua rau cov nqaws tuaj koom ua ke.
Cov yam ntxwv ntawm ERW kav:
● Lightitudinal welded seam.
● Ua los ntawm kev hla dhau cov zaus tam sim no los ntawm cov coils hlau thiab fusing qhov kawg hauv qab kev kub siab.
● Sab nraud cov uas hla los ntawm ½ rau 24 ntiv.
Wallly Phab Ntsa Thuab sib txawv ntawm 1.65 txog 20 hli.
● Raug yeej yog 3 txog 12 m, tab sis ntev muaj nyob ntawm kev thov.
● Tau muaj lub tiaj, xov, lossis beveled xaus raws li tau teev tseg los ntawm tus neeg siv khoom.
● Erw kav teev tseg nyob rau Astm A53 ua lub hauv paus ntawm cov kav dej feem ntau siv tau hauv cov roj, roj, lossis vapor kua.
Cov txheej txheem tsim khoom ntawm ERW kav:
● Cov kauj hlau yog cov khoom siv hauv paus rau kev ua cov kav dej erw.
Hlau Hlau yog qhov ua rau muaj qhov dav thiab ntau thiab tsawg ua ntej tau muab tso rau cov mills vuam.
● Cov coils hlau tsis muaj ris ntawm lub pob nkag ntawm lub pob zeb thiab hla lub zeb los tsim cov raj ua kom zoo li ib tug.
● Ntau ntau yam kev qhia xws li leeg vuam, nyem vuam, thiab kev tawm tsam kev ntsuas vuam siv.
Cov Hluav Taws Xob Tshaj Plaws, Cov Hluav Taws Xob Tsawg Tshaj dhau los ntawm Copper Electrounes Clamping rau Steel Yeeb Rau Cov Khoom Siv Steel
Rush Flash welding yog siv ib feem ntau siv raws li nws tsis xav hadering cov khoom.
Arc Arc Tawm cov hom ntawv nruab nrab ntawm cov npoo, thiab thaum mus txog qhov ntsuas kub, cov nqaws tau nias ua ke rau weld cov khoom.
● Vuam hlaws ntau qee zaum txiav cov cuab yeej carbide, thiab thaj chaw welded tau tso cai rau txias.
● Lub tubing txias yuav nkag mus rau ib qho sizing yob kom ua kom muaj cov taub sab nraum sab nraud raws li cov kev cai tshwj xeeb.
Cov ntawv thov ntawm ERW kav:
Qhov kev siv cov kav dej ntau tshaj plaws yog li kab kav dej nqa cov roj crude, nkev, thiab lwm yam khoom siv. Lawv muaj cov kab uas hla siab dua li cov kav dej tsis muaj zog thiab tuaj yeem ntsib cov kev xav tau siab thiab qis-siab, ua rau lawv muaj peev xwm thauj khoom pipes.
● ERW kav, tshwj xeeb tshaj yog ntawm cov ntsiab lus API 5ct, yog siv nyob rau hauv casing thiab tubing
● ERW kav yuav tau siv raws li cov qauv tubes rau cua fais fab nroj tsuag
● ERW kav yog siv nyob rau hauv kev lag luam ntau lawm li kev coj tes tsho, ua cov tshuab ua txhua yam, ua tshuab, thiab lwm yam
● Erw cov yeeb nkab siv suav nrog cov zaub mov roj, cov kua hluav taws xob hluav taws xob hluav taws xob fais fab, thiab ntau dua.
● Lawv kuj muaj kev siv hauv av, av hauv av, kev thauj mus los hauv av, thiab dej kub thauj.
