Munyika yekugadzira maindasitiri, kunyanya muchikamu chesimba, mhando yewelds mukugadzirwa kwepombi yakakosha. Izvi zvinonyanya kuitika kune mapaipi egasi, uko kutendeseka kweweld kunogona kureva musiyano pakati pekuchengetedza nenjodzi. Pafekitori yedu muCangzhou, Hebei Province, tinonzwisisa basa rakakosha rinoitwa nemhando yeweld mukuona kuvimbika uye kuchengetedzeka kwezvigadzirwa zvedu. Kambani yedu yakavambwa muna 1993 uye yakakura kusvika 350,000 square metres, yakazara midziyo yeRMB 680 miriyoni, uye 680 vashandi vakazvipira.
Chimwe chezvinhu zvakakosha zvekufunga kana arc welding magasi echisikigo mapaipi ndiyo mhando yewelding tekinoroji inoshandiswa. Forspiral welded pipe, nzira yakajairika ndeye submerged arc welding (SAW) nzira. Iyi tekinoroji inofarirwa nekugona kwayo kugadzira yakasimba, yakasimba, yemhando yepamusoro welds. Iyo yakanyura arc welding process inosanganisira kuumbwa kwearc pakati peiyo inoramba ichidyiswa electrode uye workpiece, iyo inonyudzwa pasi pechikamu chegranular flux. Izvi hazvingodziviriri weld kubva pakusvibiswa, asi zvakare inovandudza kunaka kweiyo weld nekupa arc yakagadzikana uye kuderedza spatter.
Kukosha kwepipelinewelding quality haigone kuwedzeredzwa. Mukutakurwa kwegasi rechisikigo, chero kutadza kwewelding kunogona kukonzera njodzi, kusanganisira kuvuza, kuputika uye kukanganisa kwezvakatipoteredza. Naizvozvo, kuve nechokwadi chekuti maitirwo ewelding anosangana nepamusoro-soro ndiyo inonyanya kukosha. Kuzvipira kwedu kumhando kunotanga nekusarudzwa kwezvinhu zvakabikwa uye kunoenderera mberi kuburikidza nedanho rega rega rekugadzira, kusanganisira kuomarara kuyedzwa uye kuongororwa kwewelds.
Panzvimbo yedu yeCangzhou, tinoshandisa tekinoroji yepamusoro uye matekinoroji ane hunyanzvi kuona kuti yedu yakanyura arc welding process inounza mhedzisiro. Chikwata chedu chakadzidziswa kunyatso tarisa uye kudzora welding paramita, kuve nechokwadi chekuti weld yega yega inosangana nezvinodiwa zvakatemerwa neindasitiri zviyero. Uku kutarisisa kune zvakadzama hakungonatsiridza hunhu hwemapombi edu egasi, asi zvakare kuwana kuvimba kwevatengi vedu, vanovimba nezvigadzirwa zvedu zvekuchengetedza uye zvine simba zvekufambisa simba.
Pamusoro pezvo, pombi weld mhando inokanganisa zvakananga kuita kwese uye hupenyu hwepombi. Yepamusoro-sorotube weldkuderedza mukana wekugadzirisa nyaya uye kuwedzera hupenyu hwepombi, pakupedzisira kuchengetedza mari kune vatengi vedu. Muindastiri umo kuvimbika kwakakosha, kuisa mari mumhando yepamusoro weld inopfuura kungosarudza; chinhu chinodiwa.
Mukupedzisa, kukosha kwepipeline welding quality mukugadzirwa kwemapombi egasi chaiwo haigoni kuregererwa. Semugadziri anotungamira muindasitiri, kuzvipira kwedu pakushandisa matekinoroji epamberi senge akanyura arc welding uye kutarisa kwedu pakutonga kwemhando kunoita kuti tive shamwari yakavimbika kune vatengi vedu. Neanopfuura makore makumi matatu echiitiko uye nevashandi vakazvitsaurira, tinoenderera mberi tichiisa pamberi pekuchengetedza uye kuvimbika kwezvigadzirwa zvedu, tichiona kuti tinozadzisa zvinodiwa neindasitiri yesimba iri kusimukira. Sezvatinofambira mberi, tinoramba takasimba mubasa redu rekupa iyo yepamusoro-soro yemapaipi egasi echisikigo, nokuti kana zvasvika kune simba rekufambisa, hutano hahuna kukosha chete; zvakakosha.
