Corrosion resistance ye galvanized steel pipe muChina
Nekuda kwekuti inopisa-dip galvanized seamless simbi pombi inopisa-dip galvanized, huwandu hwemarara hwakakwira zvakanyanya. Avhareji ukobvu hwemalata anodarika 65 microns, uye kushorwa kwayo kwakasiyana zvakanyanya kubva kune inopisa-dip galvanized pombi. Vagadziri vepombi dzakagarwa nemarara vanobvumidzwa kushandisa mapaipi anotonhora semapombi emvura uye gasi. Iyo galvanized layer yeinotonhora galvanized simbi pombi ndeye electroplating layer, uye zingi layer inoparadzaniswa nesimbi pombi substrate. Iyo zinc layer yakatetepa, uye zinc layer inongobatanidzwa kune simbi pombi matrix, iyo iri nyore kudonha. Naizvozvo, kusaita ngura kwayo hakuna kunaka. Mudzimba itsva, zvinorambidzwa kushandisa mapaipi esimbi anotonhora sepombi dzesimbi dzekupa mvura. Mushure mekunhonga, API mapaipi esimbi isina musono anocheneswa muammonium chloride kana zinc chloride aqueous solution kana ammonium chloride uye zinc chloride yakasanganiswa aqueous solution tank. Kuti uve nechokwadi chemhando, electro galvanizing (kutonhora plating) inonyanya kushandiswa. Iwo chete mabhizinesi madiki ane diki uye midziyo yekare anoshandisa electro galvanizing, hongu, mutengo wavo wakachipa. Bazi rekuvaka rakabvisa zviri pamutemo pombi inotonhora yekudzokera kumashure, isingazove magetsi mune ramangwana. Iko kuita kuti simbi yakanyungudutswa iite pamwe nesimbi matrix kuti ibudise alloy layer, kuitira kuti ibatanidze matrix uye coating. Kupisa dip galvanizing ndiko kutora pombi yesimbi kutanga, kuitira kubvisa iron oxide pamusoro pepombi yesimbi, wozoitumira kune inopisa dip galvanizing tank. Kupisa dip galvanizing kune zvakanakira kupfeka yunifomu, kunamatira kwakasimba uye hupenyu hurefu hwebasa. 1. Medium plate unit: inonyanya kugadzira mahwendefa akafara uye akakora ekugadzira mapombi akadzika arc welded longitudinal. Iyo longitudinal yakanyura arc welded pombi ndeyemhando yakavimbika uye inoshandiswa zvakanyanya mumutsara mukuru weoiri uye gasi yakakwira-kudzvanywa kwekufambisa.
Steckel Mill:Chigayo cheSteckel chinosanganisira chigayo chinodzokorodza uye 4-yepamusoro inodzoreredza yekupedzisa chigayo. Zvigayo zviviri zvinopisa zvemakoiri zvakaiswa pamitsetse yekutakura pamativi ese echigayo chekupedzisa. Iyo inobuda roller tafura inowanzo sanganisira laminar inotonhorera system uye coiling station. Pachigayo che steckel, iyo thermomechanical nhoroondo yehurefu hwese hwesimbi isina simbi inotsika mugokora pombi fittings inoshanduka zvakanyanya, kunyanya mukugadzirwa kweiyo micro-stainless simbi inotsikirira mugokora pombi fittings, iyo inozokanganisa zvakanyanya dhigirii recrystallization, kukura kwezviyo uye kunaya kwemvura pakupedzisa. chigayo, uye zvinotungamira kukuchinja kwakasimba mune yekupedzisira microstructure uye zvivakwa zvehurefu hwese hwesimbi isina tsvina inotsikirira elbow pombi fittings.
Semi continuous mill:kusanganisira 1 Steckel mill uye 5 yekupedzisa mill. Pachigayo chinoramba chichikunguruka, kupisa kutenderedzwa kwepombi mafittings mukupedza kupfuudza kunongogara kubva kune rumwe rutivi kuenda kune rumwe. Nguva iri pakati pekupfuura pachigayo chekupedzisa kazhinji isingasviki 3S.
CSP inoenderera mberi ichikanda nekukunguruka:kune yakaderera kabhoni manganese simbi ine niobium, vanadium uye titanium composite Microalloying paCSP mutsara wekugadzira, yakakodzera inodzorwa kutenderedza, inodzorwa kutonhora uye coiling maitiro anogona kuve nechokwadi chekuti michina zvivakwa uye microstructure yepombi fittings inosangana nezvinodiwa zvehunyanzvi zvemazuva ano X60 simbi isina tsvina inotsika gokora uye. maitiro ekusimudzira emazuva ano simbi isina stamping elbow pombi fittings. China's CSP inoenderera mberi ichikanda uye kukungurutsa mutsara wekugadzira yakagadzira X60 Stainless simbi inotsika magokora fittings, nepo vamwe vagadziri veCSP muUnited States nekune dzimwe nyika vakagadzira uye vakagadzira yepamusoro-giredhi Stainless simbi inotsikisa gokora fittings X60, X65 uye kunyange X70. Iyo maitiro ekuita ndeyekuti pane yepakati kupatsanurwa mukuenderera mberi kukanda nhete slab. Kubviswa kwekupatsanurwa kwepakati mukuenderera mberi nekukandira ganda rakatetepa nesimbi isina musono pombi ndiro dambudziko rakakosha rehunyanzvi kuti uwedzere kuvandudza kunaka kwesimbi isina tsvina yekutsika magokora mafittings. Mahwendefa aishandiswa simbi isina tsvina yekutsika gokora ainyanya kushandiswa A3 uye 16Mn akagadzirwa naAngang nevamwe vagadziri muma1960 nema1970. Nekuwedzera kwepombi dhayamita uye kutapurirana kumanikidza, Simba repombi yekuisa ndiro haigone kuita zvinodiwa. Mushure memakore ekuma1980, mafekitori ese epetroleum welded pombi epaipi akatanga kushandisa mapaipi esimbi mahwendefa akagadzirwa zvinoenderana neAmerican API zviyero. Panguva iyoyo, nekuda kwehunyanzvi hwekuita tekinoroji yevagadziri vesimbi isina simbi inotsikirira elbow plate, mahwendefa aitengeswa kunze kwenyika ainyanya kushandiswa.
