Inkcazo yombhobho womgca: 8-1240 × 1-200mm

umgangatho: API SPEC 5L

Ukusetyenziswa: isetyenziselwa ukuthutha igesi, amanzi kunye neoyile kwimizi-mveliso yepetroleum kunye negesi yendalo.

I-API SPEC 5L-2007 (inkcazo yombhobho womgca), ehlanganiswe kwaye ikhutshwe yi-American Petroleum Institute, isetyenziswa ngokuqhelekileyo kuwo wonke umhlaba.Umbhobho womgca: I-oyile, igesi okanye amanzi aphuma emhlabeni athunyelwa kwi-petroleum kunye negesi yendalo kumashishini oshishino ngombhobho womgca.Imibhobho yomgca ibandakanya imibhobho engenamthungo kunye nemibhobho edityanisiweyo.Iziphelo zombhobho zineziphelo ezisicaba, iziphelo ezinemisonto kunye neziphelo zesokethi;iindlela zokudibanisa i-welding yokuphela, ukudibanisa ukudibanisa, ukudibanisa i-socket, njl. Izinto eziphambili ityhubhu yi-B, X42, X46, X56, X65, X70 kunye namanye amabakala ensimbi..

Umgangatho wombhobho womgca:

I-API SPEC 5L-American Petroleum Institute Standard

I-GB/T9711-China iMgangatho weSizwe

Sebenzisa:

Imibhobho yokuhambisa ioksijini, amanzi kunye neoyile esetyenziswa kumashishini epetroleum kunye negesi yendalo

Ikakhulu ivelisa amanqanaba emibhobho yentsimbi:

B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485

Ukunyamezela ubungakanani bombhobho womgca:

1.【Umlilo owahlukileyo kwimibhobho yomgca】Ubushushu obuphantsi (150-250 degrees)

Ulwakhiwo olufunyenwe ngobushushu obuphantsi bobushushu bubushushu be-martensite.Injongo yalo kukunciphisa uxinzelelo lwangaphakathi kunye nokunyanzeliswa kwentsimbi ecinyiweyo phantsi kwesiseko sokugcina ubunzima obuphezulu kunye nokumelana nokugqoka okuphezulu, ukwenzela ukuba ugweme ukutshatyalaliswa okanye ukulimala kwangaphambili ngexesha lokusetyenziswa.Isetyenziselwa ikakhulu izixhobo ezahlukeneyo zokusika i-carbon high-carbon, izixhobo zokulinganisa, i-GB/T9711.1 imibhobho yentsimbi yombhobho, iibheringi eziqengqelekayo kunye neenxalenye ze-carburized, njl.

2.【Umlilo owahlukileyo kwimibhobho yomgca】Ubushushu obuphakathi (250-500 degrees)

Ulwakhiwo olufunyenwe ngokufudumeza kubushushu obuphakathi yi-troostite epholileyo.Injongo kukufumana amandla esivuno esiphezulu, umda we-elastic kunye nokuqina okuphezulu.Ke ngoko, isetyenziswa ikakhulu kunyango lwemibhobho yentsimbi ye-GB/T9711.1 eyahlukeneyo kunye nokubumba okutshisayo komsebenzi, kwaye ubunzima emva kobushushu ngokuqhelekileyo yi-HRC35-50.

3. 【Umlilo owahlukileyo kwimibhobho yomgca】Ubushushu obuphezulu (500-650 degrees)

Ulwakhiwo olufunyenwe ngobushushu obuphezulu bobushushu bubushushu be-sorbite.Ngokwesiko, unyango lobushushu oludibanisa ukucima kunye nobushushu obuphezulu bubizwa ngokuba kukucinywa kunye nonyango olushushu, kwaye injongo yalo kukufumana iipropathi ezibanzi zoomatshini kunye namandla amahle, ukuqina, iplastiki kunye nokuqina.Ngoko ke, isetyenziswa ngokubanzi kwiimoto, i-GB/T9711.1 imibhobho yentsimbi yombhobho, izixhobo zoomatshini kunye nezinye iindawo ezibalulekileyo zesakhiwo, ezifana neentonga zokudibanisa, iibholiti, iigiya kunye ne-shafts.Ubulukhuni emva kobushushu ngokuqhelekileyo yi-HB200-330.
