1. Khetha indawo efanele nendawo yokugcina impahla

1) Indawo noma inqolobane laphoamapayipi ensimbi angenamthungoezigcinwe kufanele zikhethwe endaweni ehlanzekile nengenamanzi kahle, kude nezimboni nezimayini ezikhiqiza amagesi ayingozi noma uthuli. Ukhula kanye nayo yonke imfucumfucu kufanele kususwe endaweni ukuze kugcinwe ipayipi lensimbi elingenamthungo lihlanzekile.

2) Akumele zipakishwe kanye ne-asidi, i-alkali, usawoti, usimende nezinye izinto ezigqwalisela insimbi esitolo. Izinhlobo ezahlukene zamapayipi ensimbi angenamthungo kufanele zipakishwe ngokuhlukana ukuze kuvinjelwe ukudideka nokugqwala.

3) Amapayipi ensimbi angenamthungo anobubanzi obukhulu angapakishwa emoyeni ovulekile.

4) Amapayipi ensimbi angenamthungo anobubanzi obumaphakathi angagcinwa eshedini lempahla enomoya omuhle, kodwa kufanele embozwe ngeseyili.

5) Amapayipi ensimbi angenamthungo anobubanzi obuncane noma anodonga oluncane oluncane, amapayipi ahlukahlukene agoqekayo, akhanwayo futhi anenani eliphezulu, angagqwala kalula angenamthungo angagcinwa endaweni yokugcina impahla.

I-6) Indawo yokugcina impahla kufanele ikhethwe ngokusekelwe ezimeni zendawo. Ngokuvamile, kusetshenziswa izindawo zokugcina ezivamile ezivaliwe, okungukuthi, izindawo zokugcina izimpahla ezinezindonga ophahleni, iminyango eqinile namafasitela, nemishini yokufaka umoya omncane.

7) Indawo yokugcina impahla idingeka ukuthi ifakwe umoya ngezinsuku ezinelanga, ivalwe ukuze kuvinjelwe umswakama ezinsukwini zemvula, futhi indawo yokugcina impahla kufanele inakekelwe ngaso sonke isikhathi.

2. Ukupakisha okunengqondo kanye nokuqala kokuphuma kuqala

I-1) Imfuneko yomgomo yokupakisha amapayipi ensimbi angenamthungo ukupakisha ngokwezinto zokwakha kanye nokucaciswa ngaphansi kwemibandela yokupakisha okuzinzile kanye nokuqinisekisa ukuphepha. Amapayipi ensimbi angenamthungo wezinto ezihlukene kufanele apakishwe ngokuhlukana ukuze avimbele ukudideka nokugqwala.

2) Akuvunyelwe ukugcina izinto ezigqwalile kumapayipi angenamthungo eduze nendawo yokupakisha.

3) Iphansi lesitaki kufanele liphakame, liqine, futhi liyisicaba ukuze kuvinjelwe amapayipi ekubeni manzi noma akhubazeke.

4) Izinto zohlobo olufanayo zipakishwe ngokwehlukana ngokuya ngendlela ezibekwe ngayo endaweni yokugcina, ukuze kube lula ukuqaliswa komgomo wokufika kuqala.

5) Amapayipi ensimbi angenamthungo anobubanzi obukhulu apakishwe endaweni evulekile kufanele abe namaphedi okhuni noma izicucu zamatshe ngaphansi, futhi indawo enqwabelene kufanele itsheke kancane ukuze kube lula ukugeleza kwamanzi. Naka ukuzibeka ziqonde ukuze uvimbele ukugoba nokuguqulwa.

6) Ubude bokunqwabelanisa akumele budlule ku-1.2m ekusebenzeni ngezandla, u-1.5m wokusebenza ngomshini, futhi ububanzi besitaki akumele budlule ku-2.5m.

7) Kufanele kube nomzila othile phakathi kwezitaki, futhi isiteshi sokuhlola ngokuvamile sibe ngu-O. 5m. Ishaneli yokufinyelela incike kusayizi wepayipi elingenamthungo kanye nezinto zokuthutha, ngokuvamile eziyi-1.5~2.0m.

8) Iphansi lesitaki kufanele liphakanyiswe. Uma inqolobane iphansi usimende libalele, ukuphakama kufanele kube ngu-0.1m; uma kuyindawo yodaka, ukuphakama kufanele kube ngu-0.2 ~ 0.5m. Uma kuyindawo evulekile, iphansi likasimende kufanele lihlanganiswe ngobude obungu-0.3 kuya ku-0.5m, futhi indawo yesihlabathi nodaka kufanele ihlanganiswe nobude obuyi-0.5 kuya ku-0.7m.

Amapayipi ensimbi angenamthungo esinawo esitokweni unyaka wonke ahlanganisa: amapayipi ensimbi angenamthungo,A335 P5, P11, P22,12Cr1MoVG, 15CrMoG. Kanye ne-carbon steel pipeI-ASTM A106impahla engu-20#, njll., zonke zigcinwa endlini, esitokweni, zilethwa ngokushesha kanye nekhwalithi enhle.
