Liyini ipayipi/ishubhu le-LSAW?

Ipayipi / Ipayipi ye-LSAWUbhavuingUmkhiqizi,Umphakeli/Isitokoyepayipi le-LSAW, ipayipi le-LSAWUmthumeli ngaphandleISHAYINA.

1.ISINGENISO NGOKUJWAYELEKILE KWE-LSAW PIPE

Ipayipi Le-Arc Welding Elifakwe Kade Engaphansi (elifushanisiwe njengepayipi le-LSAW).I-Longitudinally Submerged Arc Welding (LSAW) ikhiqizwa kusetshenziswa ipuleti elilodwa njengempahla eluhlaza, ngokucindezela (ukugingqa) ipuleti lensimbi libe yipayipi elingenalutho esikhunjeni noma emshinini wokubumba, futhi yamukele ukushisela kwe-arc ezinhlangothini ezimbili kanye nokwandisa ububanzi.Umkhiqizo oqediwe unezinhlobonhlobo zokucaciswa, futhi i-weld inokuqina okuhle, ipulasitiki, ukufana nokubumbana, futhi inezinzuzo zobubanzi bepayipi elikhulu, udonga lwamapayipi aminyene, ukumelana nokucindezela okuphezulu, ukumelana nokushisa okuphansi nokumelana nokugqwala.

Lapho wakha amapayipi aphezulu, aqine kakhulu, ekhwalithi ephezulu kawoyela negesi amabanga amade, iningi lamapayipi ensimbi adingekayo amapayipi anobubanzi obukhulu anodonga oluqondile lwe-arc ashiselwe.Ngokwezinga le-API, emapayipini amakhulu kawoyela negesi, ipayipi elishiselwe i-arc elinethungo eliqondile liwukuphela kohlobo lwepayipi olukhethiwe lapho udlula ezindaweni ze-Class I kanye ne-Class 2 njengendawo yokuphakama okuphezulu, ulwandle, nezindawo ezinabantu abaningi basemadolobheni.

2.IZINHLOBO ZEPIPHA LSAW

Ngokuya ngezindlela ezahlukene zokubumba, zingahlukaniswa zibe:

Ipayipi elishiselwe le-UOE:ngemva kokugoba kwangaphambili kwepuleti elilodwa lensimbi, i-U-forming, i-O-forming, i-welding yangaphakathi, i-welding yangaphandle, ukunwetshwa okubandayo kwemishini nezinye izinqubo;

Ipayipi elishiselwe i-JCOE:kuhambisana nenqubo ye-"JCOE" ye-welding pre-welding, ukwakha, ukunweba okubandayo ngemva kokushisela;

Ipayipi elishiselwe le-HME:Yakhiwa yi-"CCO" nge-mandrel rolling method, kanye nenqubo yokwandisa okubandayo ngemva kokushisela.

3.IMIPHITHA YOBUCHWEPHESHE YEPIYI LSAW

Imingcele yezobuchwepheshe eyinhloko ye-LSAW imi kanje:

Ubukhulu bodonga:6.4-23.8mm (0.252-0.94in) ebangeni lensimbi le-X80 kanye no-6.4-26.4mm (0.252-1.04in) ebangeni lensimbi le-X70.Ukushuba kodonga kungandiswa kuye kumazinga ahlukahlukene njengoba impahla yehliswa.

Izinga lomkhiqizo:ISO3183-3, API Spec 5L, GB9711, njll.

Umthungo oqondile ongaphansi kwe-arc oshiselwe ipayipi lensimbi ububanzi obufika ku-Φ406.4-Φ1422.4mm

Ipayipi lensimbi lingaba ngu-12.2m ubude futhi ukujiya kodonga kube ngu-6.4-26.4mm ebangeni lensimbi elingu-×70.

4.MIZIMPABA ZAMAI-LSAWI-PIPE:

I-1) Ipayipi yensimbi ine-weld longitudinal, futhi ama-welds angaphakathi nangaphandle ahlanganiswe nge-arc welding engaphansi kwamanzi.

I-2) Ngemuva kokwelashwa okunwetshwa komshini jikelele, ukucindezeleka kwangaphakathi kwepayipi lensimbi kuncane futhi kusatshalaliswa ngokulinganayo, okungavimbela ngempumelelo ukuqhekeka kokugqwala kwengcindezi, ukunemba okuphezulu kwe-dimensional, futhi ilungele ukwakhiwa kwe-welding endaweni.

3) Ukusebenzisa inqubo ye-weld-weld after-welding, inqubo yokushisela izinzile futhi izinga lokushisela liphezulu.

I-4) Ama-Welds kulula ukufeza ukuhlolwa okungabhubhisi ngesikhathi sokukhiqiza kanye nokuhlolwa okungabhubhisi ensimini ngesikhathi sokusetshenziswa.

5) Uhla lokucaciswa komkhiqizo lukhulu, olungaveza ububanzi obuncane, ukushuba kodonga olukhulu futhi lungakhiqiza nobubanzi obukhulu kanye nepayipi elikhulu lensimbi eliwugqinsi.

Thina JINBAICHENG sinjaloaumkhiqizi, umdayisi, umnikazi wamasheya kanye nomphakeli wohlu olunekhwalithi lwamapayipi we-LSAW.Sinekhasimende elivela eThane, Mexico, Turkey, Pakistan, Oman, Israel, Egypt, Arab,Vietnam, Myanmar.
