X60 Line Pipe, Mechanical Properties Of

I-X60 Line Pipe, ukwelashwa kokushisa okungaphezulu kuhlukaniswe izigaba ezimbili, eyodwa iwukwelashwa kokushisa kwamakhemikhali, enye eyokucisha indawo kanye nokwelashwa kokushisa okupholile, indlela yokuhlola ubulukhuni imi kanje:

[1] Ukwelashwa kokushisa ngamakhemikhali kwepayipi le-X60
-- Ukwelashwa kokushisa ngamakhemikhali ukwenza ingaphezulu leshubhu lepayipi le-X60 lingene ku-athomu eyodwa yezakhi zamakhemikhali, ukuze kushintshwe ukwakheka kwamakhemikhali, ukwakheka kanye nezakhiwo ze-X60 pipeline tube surface.Ngemva kokucisha kanye nokushisa okuphansi kwezinga lokushisa, ingaphezulu lepayipi lepayipi le-X60 linobulukhuni obuphezulu, ukumelana nokugqokwa namandla okukhathala othintana naye, futhi umnyombo wepayipi lepayipi i-X60 unamandla aphezulu kanye nokuqina.

-- Imingcele yezobuchwepheshe eyinhloko yokwelashwa kokushisa ngamakhemikhali X60 ukujula kongqimba oluqinile kanye nokuqina kwendawo.Ukujula kongqimba oluqinile kufanele kuhlolwe i-vickers hardness tester.Linganisa ibanga ukusuka endaweni yepayipi engu-X60 ukuya endaweni lapho ubulukhuni behla bufike ku-50HRC.Lokhu ukujula okusebenzayo kokuqina kokwelashwa kokushisa kwamakhemikhali kokuhlola ubulukhuni bepayipi lepayipi le-X60 kanye nokwelashwa kokushisa kokuqina kwendawo ukuqina kokutholwa kwepayipi lepayipi le-X60, kungasebenzisa i-vickers hardness tester, i-surface rockwell hardness tester noma i-rockwell hardness test ukuhlola, kuphela ugqinsi lwe-nitriding elizacile eliwugqinsi, ngokuvamile elingabi ngaphezu kuka-0.7 mm, bese lingasakwazi ukusebenzisa i-rockwell hardness tester, i-Microhardness tester ingasetshenziswa.

[2] X60 indawo yepayipi yokucisha kanye nokwelashwa kokushisa okupholile
-- Ukucisha ubuso nokwelashwa kokushisa kokushisa kuvame ukwenziwa ngokufudumeza kwe-induction noma ukushisisa ilangabi.Imingcele yezobuchwepheshe eyinhloko ubulukhuni bobuso, ubulukhuni bendawo kanye nokujula kongqimba oluqinile olusebenzayo.I-Vickers tester hardness ingasetshenziselwa ukuhlola ubulukhuni, i-rockwell noma i-surface Rockwell ubulukhuni bokuhlola.Ukukhethwa kwamandla okuhlola (isikali) kuhlobene nokujula kongqimba oluqinile olusebenzayo nobulukhuni bobuso bepayipi le-X60.Kunezinhlobo ezintathu zamamitha okuqina ahilelekile.

I-Vickers tester hardness iyindlela ebalulekile yokuhlola ubulukhuni bobuso bepayipi lepayipi le-X60 eliphathwe ukushisa.Ingasebenzisa amandla okuhlola angu-0.5 ~ 100kg ukuze ihlole isendlalelo sokuqina esingaphezulu sibe mncane njengo-0.05mm.Ukunemba kwayo kuphakeme kakhulu, futhi ingakwazi ukuhlukanisa umehluko omncane wokuqina kobuso bepayipi lepayipi le-X60 eliphathwe ngokushisa.Ukwengeza, ukujula kwesendlalelo sokuqina esisebenzayo kubuye kukalwe ngesihloli sokuqina kokuqina kwe-vickers, ngakho-ke kuyadingeka ukuhlomisa isihloli sokuqina se-Vickers samayunithi enza ukwelashwa kokushisa okungaphezulu noma asebenzise inombolo enkulu yocwephe olungaphezulu lokwelapha ukushisa.

-- Umhloli wokuqina we-Surface Rockwell nawo ulungele ukuhlola ubulukhuni bepayipi lepayipi le-X60 eliqinile.Kunezikali ezintathu ze-surface Rockwell tester ongakhetha kuzo.Ingahlola imigqa ehlukene ye-X60 eqinile enokujula kokuqina okusebenzayo okukhulu kuno-0.1mm.Nakuba ukunemba kwesihloli sokuqina sokuqina kwe-Rockwell singekho phezulu njenge-vickers hardness tester, singahlangabezana nezimfuneko njengendlela yokuhlola yokuphathwa kwekhwalithi nokuhlola ukuhambisana kwezitshalo zokwelapha ukushisa.Ngaphezu kwalokho, futhi inezici zokusebenza okulula, ukusetshenziswa okulula, intengo ephansi, ukulinganisa okusheshayo, futhi ingafunda ngokuqondile inani lobulukhuni, njll. Isihloli sokuqina sokuqina kwe-Surface Rockwell singasetshenziselwa inqwaba yokwelashwa kokushisa okungaphezulu kwepayipi le-X60 ngokushesha futhi ngaphandle ukuhlolwa okulimazayo.Lokhu kubaluleke kakhulu ekucubunguleni amapayipi e-X60 nasezimbonini zokukhiqiza imishini.

-- Umhloli wokuqina we-Rockwell nawo ungasetshenziswa lapho ungqimba oluqinile olungaphezulu luwugqinsi.Uma ukushuba kongqimba oluqinile lokwelashwa kokushisa kungu-0.4 ~ 0.8mm, isikali se-HRA singasetshenziswa, lapho ugqinsi longqimba oluqinile lungaphezu kuka-0.8mm, isikali se-HRC singasetshenziswa.

-- Vickers, Rockwell kanye ne-Surface Rockwell ubulukhuni amagugu angaguqulwa kalula abe yizinga elijwayelekile, umdwebo noma amanani obunzima adingekayo.Amathebula okuguqulwa ahambisanayo anikezwa ngamazinga omhlaba e-ISO, i-ASTM ejwayelekile yase-American kanye ne-Chinese standard GB/T.

[3] Ukwelashwa kokushisa kwendawo
-- Uma ubulukhuni bendawo bezingxenye kudingeka bube buphezulu, ukwelashwa kwendawo okucisha ukushisa kungenziwa ngokushisisa okungeniswayo nezinye izindlela.Amapayipi anjalo e-X60 ngokuvamile adinga ukumaka indawo yokwelapha ukushisa okucishayo kanye nenani lobulukhuni bendawo emdwebeni.Ukuhlolwa kokuqina kwepayipi le-X60 kuzokwenziwa endaweni eqokiwe.Ithuluzi lokuhlola ubulukhuni lingasebenzisa i-Rockwell ubulukhuni umhloli, ukuhlola ubulukhuni be-HRC, njengongqimba oluqinile lokwelashwa alujulile, lungasebenzisa umhloli wokuqina wokuqina we-Rockwell, hlola inani lobulukhuni be-HRN.
