I-ERW yi-high-frequency resistant welding-straight seam welding pipe; I-LSAW intywiliselwe i-arc welding-straight seam welding pipe; zombini zezemibhobho edityanisiweyo ethe tye, kodwa inkqubo yokuwelda kunye nokusetyenziswa kwezi zimbini zahlukile, ngoko azinakumela imibhobho edityanisiweyo ethe tye yodwa. I-SSAW-spiral welding-spiral welding pipes ixhaphake kakhulu.

Umahluko kunye nokusetyenziswa kwe-ERW, i-LSAW kunye neepayipi zensimbi ze-SSAW

Umthungo othe tye i-frequency ephezulu (i-ERW yentsimbi yombhobho) yahlulwe kwi-welding induction kunye ne-welding yoqhagamshelwano ngokweendlela ezahlukeneyo ze-welding. Isebenzisa iikhoyili ezijikelezileyo ezishushu ezibanzi njengemathiriyeli ekrwada. Emva kokugoba kwangaphambili, ukubunjwa okuqhubekayo, i-welding, unyango lobushushu, i-gluing, ukulungiswa, ukusika, ineenzuzo ze-welds ezimfutshane, ukuchaneka komgangatho ophezulu, ubukhulu bodonga obufanayo, umgangatho omhle womphezulu kunye noxinzelelo oluphezulu xa kuthelekiswa ne-spiral. Nangona kunjalo, ukungahambi kakuhle kukuba kuphela imibhobho enodonga oluncinci kunye needayamitha ezincinci kunye neziphakathi zinokuveliswa. I-Fusion, i-groove-like corrosion defects. Iindawo ezisetyenziswa kakhulu ngoku yigesi yendalo yasezidolophini kunye nothutho lwemveliso yeoli ekrwada.

Umthungo othe ngqo we-arc welding (i-LSAW yentsimbi yombhobho) iveliswa ngokusebenzisa ipleyiti enye kunye nengqimba njengento eluhlaza, ukucofa (ukuqengqeleka) ipleyiti yentsimbi kumatshini wokubumba okanye wokubumba, ukuwelda kwe-arc kumacala amabini, kunye nokwandisa ububanzi. Imveliso egqityiweyo inoluhlu olubanzi lweenkcukacha, ukuqina okuhle kwe-weld, iplastiki, ukufana kunye nokuxinana, kwaye ineenzuzo zobukhulu bombhobho omkhulu, udonga lombhobho otyebileyo, ukumelana noxinzelelo oluphezulu, ukuxhathisa ubushushu kunye nokuxhathisa ukubola. Xa usakha amandla aphakamileyo, ukuqina okuphezulu, umgama omde womgama omde kunye nemibhobho yerhasi, imibhobho yentsimbi efunekayo ubukhulu becala inobubanzi obukhulu obunodonga olungqindilili oluthe tye lwe-arc. Ngokomgangatho we-API, kwimibhobho emikhulu ye-oyile nerhasi, xa udlula kwiindawo zoMgangatho woku-1 kunye noDidi 2 (ezifana neendawo ezineentaba, amazantsi olwandle, kunye neendawo ezixineneyo zasezidolophini), i-arc ephantsi kwamanzi ethe tye kuphela kohlobo oluchongiweyo lwemibhobho. Ngokweendlela ezahlukeneyo zokubumba, inokwahlulwa ibe: U0E/JCOE/HME.

I-Spiral submerged arc welding (i-SSAW yentsimbi yombhobho) ithetha ukuba xa uqengqeleka umbhobho, isalathiso saso sangaphambili sikwi-engile (i-adjustable) ukuya kumgca osembindini wombhobho wokwenza, kwaye i-welding yenziwa ngexesha lokuqulunqa, kwaye i-weld yayo yenza umgca we-spiral. Inzuzo kukuba ukucaciswa okufanayo kunokuvelisa iibhobho zetsimbi ezinobubanzi obuhlukeneyo, izinto eziluhlaza zinoluhlu olubanzi lokuguquguquka, i-weld inokuphepha uxinzelelo oluphambili, kwaye uxinzelelo lulungile. Ukungalungi kukuba ubungakanani bejometri buhlwempuzekile. Ubude be-weld bude kunobo bomthungo othe tye. Ukuqhekeka, ama-pores, ukufakwa kwe-slag kunye nokuphambuka kwe-welding kulungele ukwenzeka. Kwiziphene ze-welding, uxinzelelo lwe-welding lukwimeko yoxinzelelo.

Inkcazo yoyilo lwemibhobho ye-oyile kunye negesi yomgama omde ichaza ukuba i-spiral submerged arc ingasetyenziswa kuphela kwi-Class 3 kunye ne-Class 4 indawo. Emva kokuphucula inkqubo yangaphandle, izinto eziluhlaza zitshintshwa ngamacwecwe ensimbi ukuze ahlukane nokwenza kunye ne-welding. Emva kwe-welding yangaphambili kunye nokuchaneka, i-diameter ye-welding iya kwandiswa emva kwe-welding ebandayo. Umgangatho we-welding usondele kumbhobho we-UOE.
Okwangoku, akukho nkqubo enjalo eTshayina. Eli linyathelo lokuphucula umzi-mveliso wethu. Umbhobho we "West-East Gas Transmission" usaveliswa ngokwenkqubo yendabuko, kodwa ububanzi bokuphela kombhobho kwandisiwe.
I-United States, iJapan kunye neJamani ngokubanzi ziyala ukusebenzisa i-SSAW kwaye zikholelwa ukuba umgca oyintloko akufanele usebenzise i-SSAW.
IKhanada ne-Itali ngokuyinxenye zisebenzisa i-SSAW, kwaye iRussia isebenzisa i-SSAW ngamanani amancinci. Baqulunqe iimeko ezongezelelweyo ezingqongqo kakhulu. Ngenxa yezizathu zembali, uninzi lwemigca yetrunk yasekhaya isasebenzisa iSSAW. Izinto ekrwada zitshintshwa zibe ipleyiti yentsimbi ukwahlula ukubunjwa kunye nokuwelda. Emva kwe-welding yangaphambili kunye nokuchaneka, ububanzi be-welding buya kwandiswa emva kwe-welding ebandayo. Umgangatho we-welding usondele kumbhobho we-UOE.
Umbhobho odityanisiweyo othe tye we-ERW usetyenziswa ngokubanzi njengendawo yokugcina iingcingo kushishino lwamandla. Iimpawu zokusebenza: I-100% yovavanyo lwe-ultrasonic yezinto zomzali iqinisekisa umgangatho wangaphakathi womzimba wombhobho; akukho nkqubo yokucheba idiskhi, kwaye izinto zomzali zinemingxuma emincinane kunye nemikrwelo; umbhobho ogqityiweyo emva kokupheliswa koxinzelelo ngokusisiseko awunalo uxinzelelo olushiyekileyo; i-weld imfutshane kwaye amathuba okuba neziphene zincinci; inokuthutha igesi yendalo emuncu efumileyo; emva kokwandiswa kobubanzi, ukuchaneka kobungakanani bejometri yombhobho wensimbi uphezulu; i-welding iqhutyelwa kumgca othe tye kwindawo ethe tye emva kokuqulunqwa kugqityiwe, ngoko ukungahambi kakuhle, ukuvulwa komthungo, kunye nomjikelezo wombhobho wedayamitha zilawulwa kakuhle, kwaye umgangatho we-welding uhle kakhulu. Imigangatho ephunyeziweyo yemveliso: API 5L, API 5CT, ASTM, EN10219-2, GB/T9711, 14291-2006 kunye neminye imigangatho yakutshanje. Amabakala ensimbi yemveliso abandakanya: GRB, X42, X52, X60, X65, X70, J55, K55, N80, L80, P110, njl. Iimveliso zisetyenziswa ngokubanzi kwioli, igesi yendalo, igesi yamalahle, imigodi yamalahle, oomatshini, umbane, ukufumba kunye nezinye iinjongo. Izixhobo zetekhnoloji yenkqubo ephezulu: ezifana nokubumba i-W-FF, i-welding high-frequency induction welding, i-ultrasonic flaw ubhaqa, ukufumanisa impazamo yemagnethi ukuvuza, kunye nezixhobo zokuvavanya eziphezulu: ezifana nohlalutyo lwe-metallographic, i-Vickers tester hardness, umatshini wokuvavanya impembelelo, i-spectrum analyzer, umatshini wokuvavanya jikelele kunye nezinye izixhobo. Iimveliso zithunyelwa eMzantsi Melika, kuMntla Melika, kwiManyano yaseYurophu, kuMzantsi-mpuma Asia nakwezinye iindawo. Ukutyhubela iminyaka, bamkelwe kakuhle ngabathengi kwihlabathi liphela.
