1. Whirihoranga kohu.I te wa e kowhiri ana i te kohua, me tino whakaaro te "unga paanga".Ko te "Taunga paanga" e pa ana ki nga taputapu e whakamahi ana i te mamaoa mo te wa poto, penei i nga taputapu horoi wai.60% o te kohi mamaoa o nga taputapu horoi wai ka pau i roto i te 5 meneti.Mena he iti rawa te kowhiringa o te kohua, karekau te waahi whakaetonga i roto i te tinana kohua, ka nui te wai ka puta mai i te wa e whakaetonga ana.Ka tino heke te tere o te whakamahi wera.I te wa ano, i te wa e horoi ana i te miihini horoi, ka whakatauhia te nui o te whakaurunga matū i raro i te nui o te wai.Mena he nui rawa te makuku o te mamaoa, ka nui rawa te rereketanga o te wai o te miihini horoi i te wa o te whakamahana, ka pa ki te kounga o te rinena.Te awe horoi.
2. Ko te whirihoranga o te whakamaroke me tutuki nga whakaritenga o nga miihini horoi rereke i te wa e whiriwhiri ana.Ko te tikanga, ko te kaha o te whakamaroke kia kotahi teitei ake i tera o te miihini horoi, a ko te rōrahi o te whakamaroke kia kotahi te taumata teitei ake i tera o te miihini horoi.Ka piki ake te tauwehenga rōrahi e 20% -30% i runga i te paerewa o te motu hei whakapai ake i te pai o te whakamaroke.Ina whakamaroke te whakamaroke i nga kakahu, ma te hau e tango te makuku.E ai ki te paerewa a-motu o naianei, ko te 1:20 te owehenga rōrahi o te whakamaroke.I te timatanga o te whakamaroke, he ranea tenei tauwehenga, engari ka maroke te rinena ki tetahi taumata, ka wetekina.I muri i tera, ka nui ake te rahi o te rinena i roto i te tank o roto, ka pa ki te whakapiri i waenga i te hau me te rinena, na reira ka roa te wa tiaki wera o te rinena.
3. I te wa e whakauru ana i te pipeline mamaoa o te taputapu, ka tūtohu kia whakauruhia te pipeline mamaoa.Ko te paipa matua he paipa paipa me te pehanga whakataurite rite ki te kohua ka taea.Ko te roopu whakaheke pehanga me whakauru ki te taha o te kawenga.Ko te whakaurunga o te paipa taputapu ka pa ki te whakamahi hiko.I raro i te pehanga o te 10Kg, he 50 mm te rere o te paipa mamaoa, engari ko te mata o te putorino he 30% iti ake.I raro i nga tikanga whakamaarama, ko te mamaoa e pau ana i nga paipa e rua i runga ake nei mo ia 100 mita ia haora he iti ake te 7Kg o mua atu i era o muri.No reira, mena ka taea, ka tohutohuhia kia whakauruhia te paipa mamaoa me te whakamahi i te paera me te pehanga whakatau rite mo te paipa matua.Mo nga pipelines, me whakauru te roopu whakaheke pehanga ki te taha o te kawenga.
