1. Masitepe
Malinga ndi malo okwera operekedwa ndi engineering Civil, chongani mzere wokwera pakhoma ndi maziko pomwe payipi ikuyenera kuyikidwa;kukhazikitsa bulaketi ya payipi ndi hanger malinga ndi chojambula ndi nambala;khazikitsani payipi molingana ndi chojambula choyika mapaipi ndi nambala yokhazikika ya payipi;Sinthani ndikuwongolera otsetsereka kwa chitoliro, konzani chithandizo cha chitoliro, ndikuyika chitolirocho.
2.Pemphani
Mayendedwe otsetsereka ndi kukwera kwa payipi ziyenera kukwaniritsa zofunikira za mapangidwe;otsetsereka a payipi akhoza kusinthidwa ndi chitsulo chothandizira mbale pansi pa chithandizo, ndi hanger akhoza kusintha ndi boom bawuti;mbale yochirikiza iyenera kutenthedwa ndi magawo ophatikizidwa kapena mawonekedwe achitsulo, Siyenera kugwidwa pakati pa chitoliro ndi chithandizo.
Flanges, welds ndi mbali zina zolumikizira ziyenera kukonzedwa kuti ziwonedwe mosavuta ndi kukonza, ndipo zisakhale pafupi ndi khoma, pansi kapena chimango cha chitoliro.
Pamene payipi idutsa pansi, chubu chotetezera chiyenera kuikidwa, ndipo chubu chotetezera chiyenera kukhala 50mm pamwamba pa nthaka.
Pamene payipi idutsa pansi, chubu chotetezera chiyenera kuikidwa, ndipo chubu chotetezera chiyenera kukhala 50mm pamwamba pa nthaka.
Mawonekedwe ndi kukwera kwa chithandizo ndi hanger ziyenera kugwirizana ndi zofunikira za zojambulazo, ndipo malo okonzekera ndi njira yokonzekera ayenera kugwirizana ndi mapangidwewo ndikukhala osasunthika komanso olimba.
Mizere ya mapaipi opingasa kapena ofukula iyenera kukhala yaudongo, ndipo malo oyika ma valve pamizere ya mapaipi ayenera kukhala ofanana.
3. Kuyika
Kuyika mapaipi kumagawidwa m'machitidwe ndi zidutswa.Chitoliro chachikulu choyamba, ndiye chitoliro cha nthambi.Chitoliro chanthambi kuchokera ku chitoliro chachikulu chiyenera kukhazikitsidwa chitoliro chachikulu chitatha.Century Star idalengeza kuti payipi yolumikizidwa ku zidazo iyenera kuchitidwa zida zitasinthidwa.
Kulumikizana kwa flange kuyenera kukhala kokhazikika ndi payipi, ndipo ma flange ayenera kukhala ofanana.Kupatuka sikuyenera kukhala kopitilira 1.5% yakunja kwa flange komanso osapitirira 2mm.Mabowo amayenera kuonetsetsa kuti mabawuti amatha kulowa momasuka, ndipo mabawuti sayenera kulowetsedwa ndi njira zokakamiza..
Ndege ziwiri za gasket ziyenera kukhala zathyathyathya komanso zoyera, ndipo sipayenera kukhala zokopa zozungulira.
Kulumikizana kwa flange kuyenera kugwiritsa ntchito mabawuti amtundu womwewo, ndipo njira yoyikamo iyenera kukhala yofanana.Pamene ma gaskets akufunika, bawuti iliyonse sayenera kupitilira imodzi, ndipo mabawuti ndi mtedza pambuyo polimbitsa ziyenera kusungunuka.
