Amapayipi ashiselwe enziwe ngamapuleti ensimbi noma amapheshana ensimbi agotshwayo abese eshiselwa. Ngokwefomu le-welding seam, ihlukaniswe yaba ipayipi elihlanganisiwe le-seam kanye ne-spiral welded pipe.
Ngokwenhloso, ahlukene ngamapayipi ashiselwe ngokuvamile, amapayipi ashiselwe uthayela, amapayipi ashiselwe aphefumulelwa umoya-mpilo, amakesi ocingo, amapayipi ashiselwe amametric, amapayipi amarola, amapayipi epompo ajulile, amapayipi ezimoto, amapayipi e-transformer, amapayipi kagesi ashiselwe anezindonga ezincane. , amapayipi kagesi ashiselwe amise okukhethekile namapayipi ashiselwe athandelene.
Ipayipi elishiselwe jikelele: Ipayipi elishiselwe elijwayelekile lisetshenziselwa ukuthutha uketshezi olunomfutho ophansi. Yenziwe ngensimbi ye-Q195A, Q215A, Q235A. Ingenziwa futhi ngezinye izinsimbi ezithambile ezishisela kalula. Amapayipi ensimbi adinga ukuhlolwa okufana nomfutho we-hydraulic, ukugoba, nokucaba, futhi anezidingo ezithile zekhwalithi yendawo. Ngokuvamile, ubude bokulethwa buba ngu-4-10m, futhi ukulethwa kobude obunqunyiwe (noma ubude obuningi) kuvame ukudingeka.
Ukucaciswa kwamapayipi ahlanganisiwe kuvezwa ngobubanzi obujwayelekile (amamilimitha noma amayintshi). I-diameter okuzisholo yona ihlukile kokwangempela. Ngokusho kokuqina kodonga olucacisiwe, kunezinhlobo ezimbili zamapayipi ashiselwe: amapayipi ensimbi ajwayelekile namapayipi ensimbi ajiyile. Okulandelayo isingeniso esifushane sokusetshenziswa kwamapayipi amaningana aqinile:
1. Amapayipi ashiselwe ngokuvamile asetshenziselwa ukuthutha uketshezi oluvamile olunomfutho ophansi njengamanzi, igesi, umoya, uwoyela, nesishifu sokushisisa.
2. Imikhono yensimbi yensimbi ye-carbon evamile (GB3640-88) amapayipi ensimbi asetshenziselwa ukuvikela izintambo ngesikhathi sokufakwa kukagesi njengezakhiwo zezimboni nezomphakathi kanye nokufakwa kwemishini nezinto zokusebenza.
3. Umthungo oqondile wepayipi kagesi oshiselwe (YB242-63) iyipayipi lensimbi lapho umthungo we-weld uhambisana nesiqondiso se-longitudinal sepayipi lensimbi. Imvamisa ihlukaniswe ngamapayipi kagesi ashiselwe kagesi, amapayipi anezindonga ezincane kagesi, amapayipi kawoyela okupholisa ama-transformer, njll.
4. Ipayipi elishiselwe i-arc elingaphansi kwamanzi elisontekile lokuthuthwa koketshezi olucindezelayo (SY5036-83) iyipayipi elishiselwe i-arc elijikelwe ngaphansi kwamanzi ukuze kuthuthwe uketshezi olucindezelayo. Yenziwe ngamakhoyili e-hot-rolled steel strip futhi yakhiwe ngokuvunguza ngokushisa okungashintshi. Ishiselwe nge-arc welding enamacala amabili. Kuyipayipi elishiselwe i-arc elijikelwe ngaphansi kwamanzi okucindezela uketshezi lokuthutha Ipayipi lensimbi lokuthunga. Amapayipi ensimbi anomthamo oqinile wokuthwala ingcindezi nokusebenza okuhle kokushisela. Baye babhekana nokuhlolwa okunhlobonhlobo okuqinile kwesayensi futhi baphephile futhi bathembekile ukuzisebenzisa. Ipayipi lensimbi linobubanzi obukhulu, ukusebenza kahle kokuthutha okuphezulu, futhi lingasindisa utshalomali ekubekeni amapayipi. Isetshenziselwa ikakhulukazi amapayipi athutha uwoyela negesi yemvelo.
5. Ipayipi elishiselwe i-Spiral seam high-frequency weld (SY5038-83) yokuthutha uketshezi oluthwele ingcindezi lenziwa ngamakhoyili ensimbi agoqelwe ashisayo njengezikhala zamapayipi, akhiwe ngokuvunguza ekushiseni okungaguquki, futhi ashiselwe ngendlela ye-high-frequency lap welding. Isetshenziselwa ukuthutha uketshezi olunengcindezi. Kuvunguza umthungo wepayipi wensimbi oshiselwe imvamisa ephezulu. Amapayipi ensimbi anomthamo oqinile wokuthwala ingcindezi, kanye nepulasitiki enhle, futhi kulula ukuwashisela nokuwenza. Ngemuva kokuhlolwa nokuhlolwa okunhlobonhlobo okuqinile nokwesayensi, aphephile futhi anokwethenjelwa ukuwasebenzisa. Amapayipi ensimbi anobubanzi obukhulu, ukusebenza kahle kwezokuthutha, futhi angasindisa utshalomali ekubekeni amapayipi. Isetshenziselwa kakhulu ukubeka amapayipi athutha uwoyela, igesi yemvelo, njll.
6. Ipayipi lensimbi eli-Spiral submerged arc welded steel (SY5037-83) lokuthuthwa koketshezi olunomfutho ophansi ojwayelekile lenziwa ngamakhoyili ensimbi agingqike ashisayo njengezikhala zamapayipi futhi lenziwa ngokuvunguza ngokwezinga lokushisa elingashintshi; yenziwe ngokushisela i-arc enezinhlangothi ezimbili okuzenzakalelayo noma ukushisela okunohlangothi olulodwa. Amapayipi ensimbi afakwe ngaphansi kwamanzi asetshenziselwa ukuthutha uketshezi oluvamile olunomfutho ophansi njengamanzi, igesi, umoya, nesitimu.
Amapayipi ashiselwe angasebenzisa izindlela ezintathu zokuhlola ubulukhuni.
