Imikhiqizo yensimbi engagqwali isetshenziswa kabanzi ezimbonini eziningi nasekusetshenzisweni kwayo ngenxa yokusebenza kwayo okuhle kakhulu kanye nezakhiwo.Namuhla, sizoxoxa ngepayipi lensimbi engenamthungo kanye nepayipi lensimbi engagqwali le-ERW, kanye nomehluko phakathi kwemikhiqizo emibili.
Kunomehluko phakathi kwepayipi lensimbi engagqwali le-ERW kanye nepayipi lensimbi engenamthungo.I-ERW Pipe ifushane nge-Electric Resistance Welding.Isetshenziselwa ukuthutha uketshezi olunjengamafutha, amagesi, njll., kungakhathaliseki ingcindezi, futhi idlala indima ebalulekile kumapayipi emhlabeni jikelele.Ngesikhathi esifanayo, iyipayipi yensimbi engenamthungo.Amapayipi ensimbi ayisikwele nawonxande angenawo amalunga namaphrofayili angenalutho asetshenziselwa ukuthuthwa koketshezi ngenxa yokugoba kwawo okuphakeme okuvelele kanye namandla e-torsion, kanye nokwenza izingxenye zesakhiwo nemishini.Ngokuvamile, amapayipi e-ERW namapayipi ensimbi angenamthungo asetshenziselwa izinhloso ezihlukahlukene.
Amapayipi ensimbi engenamthungo enziwa ngamabhilidi ayindilinga, kuyilapho amapayipi ensimbi engagqwali e-ERW enziwa ngamakhoyili ashisayo.Nakuba izinto ezimbili zokusetshenziswa zihluke ngokuphelele, kufanele kuqashelwe ukuthi ikhwalithi yomkhiqizo wokugcina - amapayipi ancike ngokuphelele kulezi zici ezimbili - ukulawulwa kwekhwalithi ngesikhathi sokukhiqiza kanye nesimo sokuqala kanye nekhwalithi yezinto zokusetshenziswa.Womabili amapayipi enziwe ngensimbi engagqwali yamabanga ahlukene, kodwa elivame kakhulu ipayipi elenziwe ngensimbi engagqwali 304.
I-billet eyindilinga iyashiswa futhi iphushelwe entweni enezimbobo ize ithathe isimo esingenalutho.Kamuva, ubude nobukhulu bawo kulawulwa izindlela ze-extrusion.Endabeni yokukhiqizwa kwamapayipi e-ERW, inqubo yokukhiqiza ihluke ngokuphelele.Umqulu ugobekile ohlangothini lwe-axial, futhi imiphetho eguqukayo ihlanganiswe ngobude bayo bonke ngokushisela ukumelana.
Amashubhu ensimbi engenamthungo ahlanganiswe ngokugcwele emugqeni womhlangano futhi atholakala ku-OD kufika kumayintshi angu-26.Ngakolunye uhlangothi, ngisho nezinkampani zensimbi eziphambili kakhulu ezinobuchwepheshe be-ERW zingafinyelela ububanzi obungaphandle obungama-intshi angu-24.
Njengoba amapayipi angenamthungo ekhishwa, awanawo amalunga ekuqondeni kwe-axial noma kwe-radial.Amapayipi e-ERW, ngakolunye uhlangothi, enziwa ngokugobisa amakhoyili e-axis yawo emaphakathi ukuze ashiselwe ngobude bawo bonke.
Ngokuvamile, amapayipi angenamthungo asetshenziselwa ukufaka isicelo somfutho ophezulu, kuyilapho amapayipi e-ERW asetshenziselwa isevisi ezindaweni zokucindezela okuphansi nokuphakathi.
Ngaphezu kwalokho, uma kubhekwa izici zokuphepha ezingokwemvelo zamapayipi angenamthungo, asetshenziswa kakhulu kuwoyela negesi, ukuhluzwa kukawoyela nezinye izimboni zamakhemikhali, futhi inqubomgomo yokungavuzi iyadingeka ukuze kuqinisekiswe ukuphepha kwabantu kanye namabhizinisi.Ngesikhathi esifanayo, amapayipi e-ERW enziwe kahle ngaphansi kokulawulwa kwekhwalithi okuqinile angaphinde asetshenziselwe izinsizakalo ezifanayo ngaphandle kwezinsizakalo ezijwayelekile ezifana nokuthuthwa kwamanzi, isikafula kanye nokubiya.
Kuyaziwa ukuthi ukuphela kwangaphakathi kwamapayipi e-ERW kuhlala kulawulwa izindlela ezinhle zokulawula ikhwalithi, ngakho-ke ahlala engcono kakhulu kunamapayipi angenamthungo.
Endabeni ye-ASTM A53, uhlobo S lusho ukuthi alunamthungo.Uhlobo F - isithando somlilo, kodwa i-welding, thayipha u-E - ukumelana ne-welding.Yilokho kuphela.Lena indlela elula yokunquma ukuthi ipayipi alinamthungo noma i-ERW.
Ithiphu: I-ASTM A53 Grade B idume kakhulu kunamanye amabanga.Lawa mapayipi angaba nqunu ngaphandle kokunameka, noma angafakwa uthayela noma amadiphu ashisayo afakwe uthayela futhi enziwe kusetshenziswa inqubo yokukhiqiza eshiselwe noma engenamthungo.Emkhakheni kawoyela negesi, amapayipi e-A53 asetshenziselwa izinhlelo zokusebenza zesakhiwo nezingabalulekile.
Uma udinga ulwazi olwengeziwe mayelana nale phrojekthi, sicela usithinte ukuze uthole isimo samanje, imininingwane yokuxhumana yeqembu lephrojekthi, njll.
