Ubukhulu bamapayipi egesi bungasukela kumayintshi angu-2 -60 ububanzi kuyilapho, kumapayipi kawoyela busukela ku-4 – 48 amayintshi ububanzi bangaphakathi kuye ngemfuneko.Ipayipi likawoyelaingenziwa ngensimbi noma ngepulasitiki kodwa esetshenziswa kakhulu yipayipi lensimbi.Amapayipi ensimbi afakwe ezishisayo ngokuvamile asetshenziselwa ukuthutha uwoyela negesi.

Izinzuzo zamapayipi ensimbi:
Amapayipi ensimbi agqitshwe amakhulu eminyaka anezakhiwo ezingajwayelekile ezihlanganisa ukumelana nokucindezeleka kokuqhekeka kwegesi yemvelo.Zingcolile futhi zinamandla okumelana nomthelela, isilinganiso esiphezulu se-HDB esingu-20°C, 60°C no-80°C, ukungena okuphansi kwe-methane ne-hydrogen.Inokusebenza okuthembekile kwe-UV okumangazayo kwesitoreji sangaphandle.I-insulation material ivamise ukuba yi-polyurethane foam (PU) esebenza kahle kakhulu ekushiseni futhi iqine ngokwemishini.

Ipayipi likawoyela negesi elihamba phambili:
Amapayipi ensimbi amancane, aphakathi nendawo amakhulu ayatholakala, kodwa amandla aphezulu ensimbi enza ukugoba nokwenza kube nzima kakhulu.Ngokuvamile, ipayipi lensimbi elithi Electric Resistance Welded (ERW) lisetshenziselwa ukucubungula uwoyela negesi kanye nemigqa yokudlulisa ebhalisiwe eqinisekisa ikhwalithi engaguquki ekusetshenzisweni kwayo.Amapayipi e-ERW mahle ngokulinganayo ezindaweni ezishisayo noma ezimanzi njengokuwela umfula kanye nezindawo ezimbi.

Ukubaluleka kwamasu okuthuthwa nokusatshalaliswa kukawoyela negesi ukuze kutholakale amandla kugcizelele ukukhiqizwa kwamapayipi ensimbi namashubhu.Ukuvikela ukugqwala, upende osuselwe emanzini lusetshenziswa endaweni yamapayipi angaphandle ukuze kuvikelwe ekugqwaleni komoya ngesikhathi sokuthutha nokugcinwa kanye ne-PE evikelayo enezingqimba ezi-3 ingasetshenziswa emapayipini ngokwesicelo seKhasimende.

Amapayipi ensimbi ahamba amabanga amade oketshezi oluvuthayo namagesi.Amapayipi kalayini angenazihibe asetshenziselwa ukwakhiwa kwamapayipi amabanga amade oketshezi oluvuthayo namagesi, amapayipi esiteshi senuzi, amapayipi esistimu yokufudumeza, amapayipi enhloso evamile.Ngakho-ke, izidingo zokuqina zamashubhu ensimbi olayini ziyinkimbinkimbi kunezidingo zesakhiwo esiqinile.

Amapayipi ensimbi olayini akhiqizwa futhi ancibilika esithandweni sikagesi, aphathwe ngama-slags okwenziwa futhi aphonswe ama-casters aqhubekayo.Inqubo yokwenza insimbi esetshenzisiwe iqinisekisa ukuzuzwa kwensimbi ehlanzekile ngamakhemikhali ngokubhekiselwa kokuqukethwe kwesulfure ne-phosphor ehlinzeka ngezici eziphakeme zokudonsa, i-ductility kanye nokugqwala kwamapayipi okumele asetshenziswe emazingeni okushisa aphansi emithonjeni ehlukahlukene yokugqwala.

Amapayipi ensimbi afakwe ku-thermal abaluleke kakhulu embonini kawoyela negesi.Amapayipi ensimbi, agqitshwe amakhulu eminyaka, anezinto ezingavamile ezihlanganisa ukumelana okuhle kakhulu nokuqhekeka kwegesi yemvelo nokungcola kwayo, ukungena okuphansi kwe-methane ne-hydrogen, isilinganiso se-HDB esiphezulu esingu-20°C, 60°C no-80°C, ngaphezu kwalokho. ukumelana nomthelela, ukuminyanisa, nokusebenza okuthembekile kwe-UV kusitoreji sangaphandle.I-insulation material ivamise ukuba yi-polyurethane foam (PU), esebenza kahle kakhulu ekushiseni futhi iqine ngokwemishini.

Amapayipi amancane, aphakathi nendawo kanye nobubanzi obukhulu ayatholakala futhi amandla aphezulu ensimbi nawo enza ukugoba nokwenza kube nzima kakhulu.Ngokuvamile, i-Electric Resistance Welded (ERW) ipayipi yensimbi isetshenziselwa ukucubungula uwoyela negesi kanye nemigqa yokudlulisa ebhalisiwe futhi iqinisekisa ikhwalithi engaguquki ekusetshenzisweni kwayo.Lawa mapayipi kawoyela nawegesi mahle ngokulinganayo ezindaweni ezishisayo noma ezimanzi ezifana nokuwela imifula kanye nezindawo ezimbi.Ukusetshenziswa kwensimbi kunikeza indinganiso yepayipi elifanele ukusetshenziswa ekudluliseni igesi, amanzi namafutha kuzo zombili izimboni zikawoyela negesi yemvelo.
