Isifinyezo: Ipayipi lensimbi elinwetshiwe ngokushisa i-A106GRB, njengepayipi lensimbi elingenamthungo elibalulekile lezimboni, lidlala indima ebalulekile ezinhlelweni zamapayipi ngaphansi kwezimo zokushisa okuphezulu kanye nokucindezela okuphezulu ngenxa yenqubo yalo yokukhiqiza eyingqayizivele kanye nokusebenza okuhle kakhulu okuphelele. Lesi sihloko sichaza kabanzi ngenqubo yokukhiqiza, izici zobuchwepheshe eziyinhloko, amasimu okusetshenziswa ayinhloko, kanye nezinzuzo ezivelele zalokhu.A106GRBipayipi elinwetshwe ngokushisa uma liqhathaniswa nezindlela zokukhiqiza zendabuko, okunikeza inkomba yokukhetha nokuklama kobunjiniyela obuhlobene.

1. Ubuchwepheshe Obuyinhloko: Ukubuka Konke Kwenqubo Yokukhulisa Okushisayo

Inqubo yokwandisa okushisayo iwubuchwepheshe obunwetshiwe bokucubungula obusekelwe ekukhiqizweni kwamapayipi ensimbi angenamthungo. Ingaphakathi layo lihilela ukuthatha ipayipi lensimbi elingenamthungo elincane (ipayipi elingumama) elenziwe ngokugoqa okushisayo noma ukudweba okubandayo, lifudumale ngokulinganayo kuze kube sebangeni lokushisa eliqiniswayo ngaphansi kwezimo zokushisa eziphakeme ezilawulwa kahle kusetshenziswa ukushisa okufakwayo okuvama okuphakathi noma isithando somshanelo wokuhamba. Ngemva kwalokho, ukwanda kwe-radial kwenziwa nge-mandrel ekhulayo yangaphakathi (njenge-plug ekhonjisiwe) ukuze ekugcineni kutholakale ipayipi lensimbi elinobubanzi obukhulu elifunekayo.

Isihluthulelo sale nqubo sisekulawuleni izinga lokushisa okunembile kanye nokuphathwa kokuguquguquka, ukuqinisekisa ukugeleza kwensimbi okufanayo kanye nesakhiwo se-metallographic esizinzile noma esilungiselelwe kahle (ngokuvamile i-ferrite + pearlite yensimbi yeBanga B) ngesikhathi sokunwetshwa, ngaleyo ndlela kuqinisekiswa ukuthi izakhiwo zemishini zomkhiqizo wokugcina ziyahlangabezana noma zidlula izidingo ezijwayelekile.

2. Izici Eziyinhloko Zepayipi Elinwetshiwe Elishisayo le-A106GRB

Ipayipi elinwetshiwe ngokushisa i-A106GRB lihambisana ne-I-ASTM A106ejwayelekile, lapho i-"GR.B" ikhombisa ukuthi izinga layo lezinto ezibonakalayo lingu-B. Izici zayo eziyinhloko yilezi:

1. Izakhiwo Ezinhle Kakhulu Zomshini: Ngemva kokwandiswa okushisayo nokwelashwa okulandelayo, ipayipi kumele lihlangabezane nezidingo zezakhiwo zomshini ze-ASTM A106 GR.B, kanti amanani ajwayelekile anamandla okudonsa≥415 MPa kanye namandla okukhiqiza≥I-240 MPa, ihlanganisa amandla amahle nokuqina okuthile.

2. Izinga Lokushisa Elithembekile Nokumelana Nokucindezela: Yakhelwe ngqo isevisi yokushisa okuphezulu kanye nokucindezela okuphezulu. Igcina amandla aphezulu emazingeni okushisa aphezulu (isb., afinyelela cishe ku-450 degrees Celsius)°C), okwenza ifanelekele ukudlulisa izinto ezifana nomusi kanye namafutha/igesi okushisa okuphezulu.

3. Ukuguquguquka Okuhle Kobukhulu kanye Nokusebenza Kahle Kwezindleko: Inqubo yokukhulisa eshisayo ingakhiqiza amapayipi ahlukahlukene aqediwe anobubanzi obukhulu avela ku-mother pipe specification efanayo, idlula imikhawulo yamandla emishini emikhulu yamapayipi engenamthungo. Ingcono kakhulu futhi iguquguquka ekukhiqizeni amapayipi anobubanzi obukhulu, anodonga olujiyile uma kuqhathaniswa namapayipi aqondile angenamthungo anobubanzi obukhulu agoqwe ngokushisa, futhi inciphisa izikhathi zokulethwa.

4. Imvelo Engagoqeki Egcinwe: Naphezu kokucutshungulwa kwesibili, ipayipi eliqediwe lihlala lingenamthungo lilonke, ligwema izindawo ezibuthakathaka ezingaba khona ezihlobene nokushisela, okuholela ekuqhubekeni okuhle.

3. Izinkambu Eziyinhloko Zokusebenza

Ukusebenzisa lezi zici ezingenhla, amapayipi anwetshiwe ashisayo e-A106GRB asetshenziswa kabanzi ku:

•Izinhlelo Zokushisa Zezitshalo Zikagesi: Zezingxenye zokushisa okuphezulu kanye nengcindezi ephezulu yemigqa eyinhloko yomusi bese uphinda ufudumale imigqa yomusi.

•Imboni Ye-Petrochemical: Amapayipi enqubo yokushisa okuphezulu ezindaweni zokucwenga, izitshalo zamakhemikhali, amapayipi esithando se-pyrolysis, njll.

•Izinhlelo Zokushisa: Imigqa eyinhloko yokudlulisa amanzi ashisayo ashisa kakhulu ezinhlelweni zokushisa zesifunda.

•Ukudluliswa Kwamafutha Negesi: Amanye amapayipi okudlulisa amabanga amade ngaphansi kwezimo zokusebenza ezishisa kakhulu.

•Ezinye Izinkambu Zezimboni: Imishini ehlukahlukene yezimboni exhuma amapayipi adinga ukumelana nokushisa okuphezulu kanye nokucindezela.

4. Isifinyezo Sezinzuzo Eziyinhloko

Uma kuqhathaniswa namapayipi endabuko ahlanganisiwe ngomthungo we-longitudinal noma amapayipi angenamthungo ngezincazelo eziphelele, izinzuzo zamapayipi anwetshiwe ashisayo e-A106GRB yilezi:

•Ibhalansi "Ububanzi Obukhulu" kanye "Nokungenamthungo": Inikeza ikhambi elithembekile lamapayipi amakhulu angenamthungo.

•Ukuhambisana Nokusebenza, Ukulawula Ikhwalithi: Izinqubo zokwelashwa kokushisa ezivuthiwe ziqinisekisa ukuthi izakhiwo zemishini kanye nesakhiwo esincane ziyahlangabezana noma zidlula izidingo ezijwayelekile.

•Ukusebenza Kahle Kakhulu Kwezindleko: Kusebenza kahle kakhulu futhi kuyaguquguquka ekukhiqizeni kobubanzi obuthile bosayizi uma kuqhathaniswa namapayipi amakhulu angenamthungo aqhutshwa ngokugcwele ashiswayo anencazelo efanayo.

•Amandla Nokuphepha Okuphezulu Kokucindezela: Isakhiwo esingenamthungo sigwema ukushintshwa kwe-longitudinal, sinikeza ukufana okwengeziwe ngaphansi kokucindezeleka okuzungezile, okulungele izimo ezidinga amandla.

Ipayipi elinwetshiwe elishisayo le-A106GRB liyimpumelelo ebalulekile kubuchwepheshe besimanje bokukhiqiza amapayipi ensimbi. Ligcwalisa ngempumelelo isidingo semakethe ngale komkhawulo ophezulu wezimiso ezijwayelekile zamapayipi angenamthungo aqhutshwa ngokushisa ngenkathi ligcina ukuphepha nokuthembeka kwamapayipi angenamthungo. Ekwakhiweni kwezimboni ezibalulekile emnothweni wezwe, njengamandla kagesi kanye namakhemikhali e-petroleum, ukukhethwa okufanele kwamapayipi anwetshiwe aqhutshwa ngokushisa e-A106GRB ahambisana nezindinganiso kubaluleke kakhulu ekuqinisekiseni ukusebenza kwesikhathi eside okuphephile, okuzinzile, nokonga kwezinhlelo zamapayipi. Ngesikhathi sokukhetha, iziqu zenqubo yomenzi, uhlelo lokulawula ikhwalithi, kanye nemibiko yokuhlola umkhiqizo kufanele kubuyekezwe ngokuqinile ukuqinisekisa ukuhambisana ngokugcwele nezimiso ezijwayelekile ze-ASTM A106.
