Njengamanje, amapayipi asetshenziswa kakhulu ekuthuthweni kukawoyela negesi amabanga amade. Amapayipi ensimbi epayipi asetshenziswa kumapayipi akude ikakhulukazi ahlanganisaamapayipi ensimbi ashiselwe i-arc angaphansi kwe-spiralkanye namapayipi ensimbi ashiselwe ngomthungo oqondile anezinhlangothi ezimbili. Ngenxa yokuthi ipayipi elihlanganisiwe le-arc elihlanganisiwe lenziwe ngensimbi ye-strip futhi ubukhulu bayo bodonga bulinganiselwe, ukuthuthukiswa kwebanga lensimbi kunqunyelwe ukwelashwa kokushisa kwempahla. Ukwengeza, kukhona ukushiyeka okungenakunqobeka kwepayipi elishiselwe i-arc elijikelwe emanzini, njenge-weld ende, ingcindezi enkulu eyinsalela kanye nokwethenjwa okubi kwe-weld. Ngezidingo ezikhulayo zamapayipi ensimbi adlulisa uwoyela negesi, awasasetshenziswa ezindaweni ezinabantu abaningi nasezindaweni ezinezidingo ezinokwethenjelwa okuphezulu, futhiamapayipi ashiselwe aqondile anobubanzi obukhulukancane kancane bashintsha amapayipi ashiselwe athandelene.
Muva nje, i-China isheshisa ukuthuthukiswa kukawoyela negesi e-East China Sea. Ngokuthuthuka kokuxhashazwa kukawoyela ekujuleni kolwandle, ipayipi elibekwe phansi olwandle lithintwa amandla ahlangene okucindezela, amandla okushayisana namandla okugoba, futhi kusabonakala isenzakalo sokucaba, okuyisixhumanisi esibuthakathaka se-spiral welded. ipayipi. Ukuze kuthuthukiswe umthamo wokuthutha wamapayipi kanye nokuqinisekisa ukuthi ipayipi elihamba ngaphansi kwamanzi lizothuthukela odongeni oluwugqinsi, ipayipi elingaphansi kwamanzi ngokuvamile lithatha ipayipi elishiselwe ngqo. Ngakho-ke, uma kuqhathaniswa nepayipi elishiselwe okuvunguzayo, ipayipi elishiselwe ngokuqondile linobude obuphakeme bokunemba kanye ne-welding yokulungisa kalula, ngakho-ke kulesi sici, ipayipi elihlanganisiwe eliqondile liwukhetho lokuqala.
Imishini, ukwakhiwa, imboni yamakhemikhali nezinye izimboni zidinga amapayipi ashiselwe aqondile. Njengamanje, imbobo yangaphakathi yesihlalo se-valve yenziwa ngomshini ngemuva kokwakhiwa embonini yemishini, edla umsebenzi, edla isikhathi futhi edla izinto ezibonakalayo. Uma kusetshenziswa ipayipi elishiselwe ngomthungo owugqinsi elinezindonga eziqinile, kuzoba ukonga kakhulu. Ngaphezu kwalokho, ngenxa yezidingo zemishini ye-anti-flattening, amapayipi ahlanganisiwe kuphela asetshenziselwa ukwakha amapayipi; Ipayipi elishiselwe ngokuqondile kulindeleke ukuthi lisetshenziselwe amapayipi amakhemikhali.
