I-Q345 Spiral Welded Pipe
Ipayipi lensimbi elishiselwe i-Spiral seam elingaphansi kwe-arc (SY5036-83) lokuthutha uketshezi olunengcindezi lisetshenziselwa ikakhulukazi amapayipi okuthutha uwoyela negesi yemvelo; ipayipi elishiselwe i-spiral seam high-frequency welded steel (SY5038-83) yokuthutha uketshezi oluthwala ingcindezi, kusetshenziswa indlela yokushisela ye-high-frequency lap Welding, umthungo ovunguzayo wepayipi wensimbi oshiselwe imvamisa ephezulu wokuthutha uketshezi olunomfutho. Ipayipi lensimbi linomthamo oqinile wokuthwala ingcindezi kanye nepulasitiki enhle, elungele ukushisela nokucubungula. Ngokuvamile, uthungelwano oluvunguzayo olungaphansi kwamanzi lwe-arc olushiselwe ipayipi lensimbi (SY5037-83) lokuthuthwa koketshezi olunomfutho ophansi lwenziwa ngokushisela okuzenzakalelayo okungaphansi kwe-arc okunezinhlangothi ezimbili noma ukushisela okunohlangothi olulodwa lwamanzi, ipayipi lensimbi elifakwe ngaphansi kwe-arc elishiselwe ukudlulisa uketshezi oluvamile lwengcindezi ephansi. njengegesi, umoya nesitimu
(1) Izinto ezisetshenziswayo amakhoyili ensimbi ehlutshiwe, izintambo zokushisela, nama-fluxes. Ukuhlolwa okuqinile ngokomzimba namakhemikhali kuyadingeka ngaphambi kokutshala imali.
(2) Inhlanganisela yezinqe yekhanda nomsila we-strip, sebenzisa i-arc welding eyodwa noma izintambo ezimbili ezingaphansi kwamanzi, ngemva kokuboshelwa epayipini lensimbi, sebenzisa i-arc yokushisela engaphansi kwamanzi ukuze ilungise ukushisela.
(3) Ngaphambi kokwakhiwa, i-strip yenziwa ileveli, ukunqunywa konqenqema, i-edge planing, ukuhlanzwa kwendawo kanye nokudlulisa, kanye nokwelashwa kwangaphambili kokugoba.
(4) Igeji yokulinganisa ingcindezi kagesi isetshenziselwa ukulawula ukucindezelwa kwamasilinda ezinhlangothini zombili zomhambisi ukuze kuqinisekiswe ukuhanjiswa okushelelayo komugqa.
(5) Yamukela isilawuli sangaphandle noma ukwakhiwa komqulu wokulawula wangaphakathi.
(6) Idivayisi yokulawula igebe lokushisela isetshenziselwa ukuqinisekisa ukuthi igebe le-welding seam lihlangabezana nezidingo zokushisela, kanye nobubanzi bepayipi, inani lokungahambi kahle kanye negebe le-welding seam konke kulawulwa ngokuqinile.
(7) Kokubili ukushisela kwangaphakathi nokushisela kwangaphandle kusebenzisa umshini wokushisela we-American Lincoln kagesi wocingo olulodwa noma i-double-wire submerged arc welding, ukuze kutholwe ukucaciswa kokushisela okuzinzile.
(8) Ama-seam ashiselwe wonke ahlolwa ithuluzi elisebenza nge-inthanethi eliqhubekayo le-ultrasonic, eliqinisekisa ukumbozwa kokuhlola okungabhubhisi okungu-100% kwama-spiral weld. Uma kunesici, kuzokwethusa ngokuzenzakalelayo futhi kufafaze uphawu, futhi izisebenzi zokukhiqiza zingalungisa imingcele yenqubo nganoma yisiphi isikhathi ngokusho kwalokhu ukuze kuqedwe iphutha ngesikhathi.
(9) Umshini wokusika i-air plasma usetshenziselwa ukusika ipayipi lensimbi libe yizicucu ngazinye.
(10) Ngemva kokusika emapayipini ensimbi eyodwa, iqoqo ngalinye lamapayipi ensimbi kufanele ahlolwe kuqala ukuze ahlole izakhiwo zemishini, ukwakheka kwamakhemikhali, isimo sokuhlangana kwamapayipi okushisela, ikhwalithi engaphezulu yamapayipi ensimbi kanye nokuhlola okungacekeleli phansi. ukuqinisekisa ukuthi inqubo yokwenza amapayipi ifanelekile. Ngemuva kwalokho, ingafakwa ngokusemthethweni ekukhiqizeni.
(11) Izingxenye ezinamamaki okuthola amaphutha e-sonic aqhubekayo ku-weld zihlolwa kabusha nge-manual ultrasonic ne-X-ray. Uma kunesici, ngemva kokulungiswa, kuzophinde kudlule ekuhloleni okungabhubhisi kuze kube yilapho kuqinisekiswa ukuthi iphutha lisusiwe.
(12) Amapayipi lapho umthungo wokushisela izinqe zensimbi uthunga kanye namajoyinti amise okuka-D aphambana nama-spiral welding seams ahlolwa ngomabonakude we-X-ray noma ukuqoshwa.
(13) Ipayipi ngalinye lensimbi lihlolwa ingcindezi ye-hydrostatic, futhi ingcindezi ithatha uphawu lwe-radial. Ingcindezi yokuhlola nesikhathi kulawulwa ngokuqinile ipayipi lensimbi le-hydraulic microcomputer idivayisi yokubona. Imingcele yokuhlola iphrintwa futhi irekhodwe ngokuzenzakalelayo.
(14) Isiphetho sepayipi sicutshungulwa ngomshini, ukuze ukuma kobuso bokuphela, i-engeli ye-bevel kanye nonqenqema lwe-obtuse kulawulwe ngokunembile.
Njengamanje, izindinganiso ezivame ukusetshenziswa zamapayipi ensimbi okuvunguza ngokuvamile zihlukaniswa zibe: SY/T5037-2000 (Izinga likaNgqongqoshe, elibizwa nangokuthi i-spiral seam submerged arc welded steel pipe yamapayipi ajwayelekile okuthutha uketshezi), GB/T9711.1-1997 (National okujwayelekile, okubizwa nangokuthi ukuthuthwa kwezimboni zikawoyela negesi Ingxenye yokuqala yezimo zokulethwa kwezobuchwepheshe zamapayipi ensimbi: Amapayipi ensimbi eBanga A (amapayipi amaningi kakhulu Izidingo eziqinile amapayipi ensimbi e-GB/T9711.2 Grade B), API-5L (American Petroleum Institute, ebizwa nangokuthi amapayipi ensimbi; ihlukaniswe yaba izinhlobo ezimbili: PSL1 kanye PSL2 Grade), SY/T5040-92 (Spiral submerged arc ipayipi lensimbi elishiselwe inqwaba)
I-Spiral tube impahla:Q235A, Q23b, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb. Q345 L245 L290 X42 X46 X70 X80
Amapayipi ensimbi okuvunguza asetshenziswa kakhulu kubunjiniyela bokuhlinzekwa kwamanzi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla kagesi, ukuchelela ngenkasa kwezolimo, kanye nokwakhiwa kwamadolobha. Ingenye yemikhiqizo engu-20 ebalulekile eyenziwe ezweni lami.
Isetshenziselwa ukuthutha uketshezi: amanzi, amanzi. Isetshenziselwa ukuthuthwa kwegesi: igesi yamalahle, umusi, igesi ye-petroleum ewuketshezi. Ngezinhloso zesakhiwo: njengamapayipi okunqwabelanisa, njengamabhuloho; izinsimbi, imigwaqo, izakhiwo zokwakha, njll.
