Iingenelo kunye nezicelo zeeMbhobho zeNsimbi eziDityanisiweyo eziSpiral (ASTM A252)

Yazisa:

Iipayipi zentsimbi ziyinxalenye ebalulekileyo yamashishini ahlukeneyo kwaye zinceda ekuthuthweni kolwelo, iigesi kwanezinto eziqinileyo. Olunye uhlobo olubalulekileyo lweepayipi zentsimbi oluye lwathandwa kakhulu ngokuhamba kwexesha yipayipi yentsimbi edibeneyo ejikelezayo. Le bhlog iza kujonga ngokunzulu iingenelo kunye nokusetyenziswa kwepayipi yentsimbi edibeneyo ejikelezayo, igxile ngokukodwa kumgangatho we-ASTM A252.

Iingenelo zeumbhobho odibeneyo ojikelezayo (ASTM A252):

1. Amandla kunye nokuqina kwesakhiwo:

Umbhobho wentsimbi odibeneyo ojikelezayo unomgangatho ogqwesileyo wesakhiwo, okwenza ukuba ufaneleke kwiimfuno ezifuna amandla aphezulu kunye nokuqina. Imigangatho ye-ASTM A252 iqinisekisa umgangatho kunye namandla ale mibhobho, nto leyo eyenza ukuba ilungele iiprojekthi ezibalulekileyo.

2. Ukusebenza kakuhle kweendleko:

Xa kuthelekiswa nezinye iindlela zokwenza imibhobho ezifana nokuwelda okungenamthungo okanye okude, imibhobho yentsimbi ewelding ejikelezayo ibonelela ngesisombululo esingabizi kakhulu. Inkqubo yokuwelda esetyenziswa kwinkqubo yokuvelisa yenza ukuba ifikeleleke ngakumbi kwaye ingabizi kakhulu ukuyivelisa, ekugqibeleni inceda ishishini kunye nabathengi.

3. Ukuguquguquka:

Umbhobho odibeneyo ojikelezayo usetyenziswa ngeendlela ezahlukeneyo kwaye ungasetyenziswa kumashishini ahlukeneyo, kuquka ioyile negesi, unikezelo lwamanzi, ulwakhiwo kunye nobunjineli be-geotechnical. Ubuninzi bezicelo zabo bubenza babe lukhetho olunomtsalane kwiiprojekthi ezininzi, nokuba zingakanani na ubukhulu kunye nobunzima bazo.

Ukusetyenziswa kombhobho wentsimbi odibeneyo ojikelezayo (ASTM A252):

1. Ishishini leoyile negesi:

Ishishini leoyile negesi lixhomekeke kakhuluimibhobho yentsimbi edibeneyo ejikelezayoukuthutha iimveliso zepetroleum kumgama omde. Amandla azo, ukuqina kwazo, kunye nokumelana namaqondo obushushu aphezulu kunye noxinzelelo kuzenza zibe lukhetho lokuqala kwimibhobho yeoyile negesi.

2. Ubonelelo lwamanzi kunye nenkqubo yogutyulo:

Kwiinkqubo zamanzi kunye namanzi amdaka, iipayipi zentsimbi ezidityanisiweyo nge-spiral zisetyenziswa kakhulu ngenxa yokukwazi kwazo ukumelana nokugqwala nokusebenza ngokuthembekileyo. Zikwazi ukuthutha amanzi amaninzi kunye nokuthutha amanzi amdaka ngokufanelekileyo, ezi pipes zibalulekile ekugcineni iziseko zophuhliso zizonke.

3. Ukwakhiwa kweziseko zophuhliso:

Umbhobho wentsimbi odibeneyo ojikelezayo ubalulekile kwiziseko zophuhliso kunye neeprojekthi zokwakha ezifana neebhulorho, iindlela ezinkulu, iitonela kunye nezibonelelo ezingaphantsi komhlaba. Le mibhobho inokumelana nemithwalo enzima kwaye ifanelekile kwizakhiwo zokuxhasa kunye neziseko kuzo zonke iintlobo zeeprojekthi zokwakha.

4. Imisebenzi yokubeka iipali kunye nesiseko:

Iipayipi zentsimbi ezidityanisiweyo ezihambelana nemigangatho ye-ASTM A252 zisetyenziswa kakhulu kwimisebenzi yokubeka iintsika kunye nesiseko ukuqinisekisa uzinzo kunye nokomelela kwesakhiwo. Zihlala zisetyenziselwa ukudala iziseko ezikhuselekileyo zezakhiwo, izakhiwo zoshishino kunye namaqonga angaphandle kolwandle.

Ukuququmbela:

 Umbhobho odibeneyo ojikelezayoihambelana nemigangatho ye-ASTM A252 kwaye inika iingenelo ezibalulekileyo kwaye inezicelo ezahlukeneyo kumashishini ahlukeneyo. Amandla azo, ukusebenza kakuhle kweendleko kunye nokuguquguquka kwazo kuzenza zibe lukhetho lokuqala kwiiprojekthi ezibalulekileyo ukusuka kwimibhobho yeoyile negesi ukuya kwiinkqubo zamanzi kunye neeprojekthi zokwakha. Njengoko itekhnoloji iqhubeka nophuhliso, ukubaluleka kunye nemfuno yemibhobho yentsimbi edibeneyo ejikelezayo kusenokwenzeka ukuba ikhule, ngaloo ndlela iququzelele uphuhliso lweeprojekthi ezininzi zoshishino kunye neziseko zophuhliso kwihlabathi liphela.
