Ngokuvamile, i-API 5L isho ipayipi lomugqa we-API 5L, elingaphandle komhlaba uwoyela, igesi, amanzi, ethuthwa ngamapayipi ezinkampanini zemboni kawoyela negesi.

ngokuya ngenqubo yokukhiqiza kanye nokuqhakaza kweshubhu kusetshenziswa ubujamo obuhlukene, i-api 5l ingahlukaniswa ibe ipayipi lensimbi elingenamthungo le-api 5l kanye nepayipi lensimbi elishiselwe i-api, phakathi kokusetshenziswa kwepayipi lensimbi elishiselwe ingaphezu kwepayipi lensimbi elingenamthungo.

Ibanga lamapayipi omugqa kanye nezingxenye zamakhemikhali

I-API 5L ingahlukaniswa ibe yi-API 5L PSL 1 ne-API 5L PSL 2, okuhlanganisa izinga le-API 5L PSL 1 futhi izigaba yilezi: A, B, x42, x46, x52, x56, x60, x65, x70, API 5L PSL 2 level futhi isigaba sithi B, x42, x46, x52, x56, x60, x65, xx70, x80.izinga eliphakeme kakhulu izici zemishini ezinamandla.

Isicelo: esetshenziselwa imboni kawoyela negesi, igesi, amanzi, ezokuthutha uwoyela.

I-API SPEC 5L Line Pipe

Inqubo yokukhiqiza ipayipi ye-API SPEC 5L ihlukaniswe yaba ipayipi lensimbi elingenamthungo, ipayipi lensimbi le-ERW, ipayipi elihlanganisiwe le-arc elingaphansi.Kodwa ukusetshenziswa okuyinhloko kwepayipi lensimbi elingenamthungo (i-Seamless), ipayipi lensimbi eliqinile eliqinile le-seam high frequency ukumelana (Electric-Resistance Arc Welding, elifushaniswe ngokuthi ERW), LSAW (Longigudinally Submerged Arc Welding short LSAW), ipayipi elishiselwe i-arc elihlanganisiwe (Spirally). I-Summerged Arc Welding, ifushane nge-SSAW) ezine.

Ipayipi le-LSAW lihlukaniswe laba yi-UO (indlela yokwenza i-UOE), i-RB (RBE), i-JCO (JCOE) nezinye izinhlobo.Ipuleti lensimbi ekubunjweni laliyocindezelwa libe okumise okwe-U, bese licindezelwa ku-O-, bese kuthi ngaphakathi nangaphandle kufakwe i-arc welding, ngemva kokushisela, ngokuvamile ekupheleni kobude obugcwele be-expander (Ukwandisa) okuthiwa. Ipayipi elishiselwe i-UOE, elingakhuli elaziwa ngokuthi yipayipi le-UO.Ukugoba kwepuleti lensimbi yokucindezela (Ukugoba kwe-Roll), bese kuba ukushisela kwe-arc okungaphansi nangaphandle, ngemva kokushisela, ukunweba ipayipi le-RBE, noma ukungakhulisi ipayipi le-RB.Ipuleti lokubumba ngokohlobo lwe-JOC-oda lokukhulisa ipayipi le-JCOE noma lingakhulisi ipayipi le-JCO ngemuva kokushisela.Amapayipi e-LSAW ngenhla, ukusetshenziswa kwe-UOE evamile.Ishubhu ye-welding ye-high frequency ukumelana ne-ERW tube embryo ngokusebenzisa umphumela wesikhumba kanye nomphumela wokusondela ku-high-frequency current kuze kube senqenqemeni lokuncibilika, bese ucindezela ama-roller ngaphansi kwe-welding yengcindezi, ebonakala ngokungabi bikho kwensimbi yokugcwalisa yangaphandle, indawo ethintekile ukushisa, ephezulu. ukusebenza kahle kokukhiqiza.Kuvunguza ipayipi lomthungo i-SSAW yepayipi lomugqa webanga elide linomlando omude, ipayipi eliseChina lisetshenziswa kakhulu.
