Raws li cov ntawv thov kev lag luam tau hloov zuj zus thiab cog cov khoom lag luam ntau, cov khoom xa khoom thiab cov tshuab uas pab lawv kom lawv tau ua kom tiav.
Txawm hais tias ntau txoj kev tsim hluav taws xob muaj nyob, qhov kev sib tham tshaj plaws hauv kev lag luam yog qhov sib piv ntawm kev tiv thaiv (ERW) thiab seamless (sms) kav hlau. Yog li qhov twg yog qhov zoo dua?
Qhov sib txawv ntawm seamless stainless hlau yeeb nkab hlau thiab welded yeeb nkab nyob rau hauv cov lus nrov tshaj plaws yog qhov txawv tsis muaj weld, txawm li cas los xij, qhov no tseem ceeb qhov sib txawv hauv cov txheej txheem ntau lawm. Nws yog qhov sib txawv ntawm cov txheej txheem ntau lawm uas muab ob qho tib si ua tau zoo thiab lub hom phiaj.
Raug Seamless Yeeb Nkab
Seamless steel yeeb nkab yog ua los ntawm tib daim ntawv hlau, saum npoo ntawm cov yeeb nkab steel yam tsis muaj qhov kab ntawm kev sib txuas, hu ua Seamless Steel Yeeb Nkab. Raws li cov qauv ntau lawm, cov yeeb nkab kub, khaub thuas dov yeeb, txias rub yeeb nkab thiab yeeb nkab yeeb nkab thiab yeeb nkab sib faib.
Seamless piping pib li cov khoom siv cylindrical hunk ntawm cov hlau hu ua ib billet. Thaum tseem kub kub, lub billet siv ib lub mandrel chob los ntawm lub chaw. Cov kauj ruam tom ntej yog kom yob thiab ncab lub hollow fillet. Cov ntses tau muab dov thiab ncab kom txog thaum ntev, txoj kab uas hla thiab phab ntsa thiab phab ntsa tuab teev nyob rau hauv cov neeg xaj khoom.
Raug Welded Yeeb Nkab
Lub xeev qub ntawm Welded yeeb nkab yog ntev, coiled steel sawb. Txiav rau qhov ntev xav tau ntev thiab dav mus ua ib daim ntawv plaub hau tiaj tus hlau. Qhov dav ntawm daim ntawv yuav dhau los ua cov yeeb nkab sab nraud ntawm cov yeeb nkab, thiab tus nqi no tuaj yeem siv los laij nws txoj kab uas hla kawg. Cov ntawv sib dhos dhau los dhau ntawm chav tsev yob yog li ntawd ob tog kom ntev dua los ua ib lub tog raj kheej. Thaum Erw, ntau zaus cov zaub uas tau kis tau ntawm cov npoo, ua rau lawv yaj thiab fuse ua ke.
Qhov sib txawv dav dav yog tias:
Welded yeeb nkab yog suav tias yog muaj qhov tsis muaj zog vim tias nws suav nrog ib Weld. Seamless tubes tsis muaj cov qauv zoo nkauj no tsis meej thiab yog yog li yog li ntawd thiaj li muaj kev nyab xeeb dua. Txawm hais tias lub yeeb nkab welded muaj xws li sib koom ua ke, txoj kev tsim no ua rau cov yeeb nkab welded ua rau tus neeg siv khoom thiab cov tuab tuab yog ib yam nkaus. Txawm hais tias lub seamless yeeb tau pom meej zoo, kev thuam ntawm cov yeeb nkab seamless yog tias dov thiab ncab cov txheej txheem ua cov tuab tuab.
Nyob rau hauv cov roj, roj, hluav taws xob ntau thiab cov ntaub ntawv lag luam, ntau cov ntawv thov kub xav tau kev siv hluav taws xob. Vuam kav yog feem ntau pheej yig dua los tsim thiab siv dav ntev li ntev tau, siab thiab lwm yam kev pabcuam hloov pauv tau teev tseg hauv cov qauv siv.
Ib yam li ntawd, tsis muaj qhov sib txawv hauv kev ua tau zoo ntawm Erw thiab seamless steel kav hauv cov ntawv thov txheej txheem txheej txheem. Thaum ob qho kev hloov pauv tau, nws ua rau tsis muaj kev nkag siab los qhia kom meej lub yeeb nkab seamam thaum tus pheej yig welded yeeb nkab yog siv tau zoo ib yam nkaus.
