Uyini bezinhlamvu ipayipi?

Okwamanje, imboni ukhiqiza izinhlobo eziningana amapayipi. Endaweni yokuqala, lapho udinga ukwaba ezimbili: coring nobukhulu bezinhlamvu. Bezinhlamvu isetshenziselwa ukuthuthukisa uwoyela negesi imithombo ngesikhathi imishini yabo kanye nentuthuko.

Bezinhlamvu okwesikhathi kahle kungaba kuqukathe izinto ezahlukene ngokuphelele: yensimbi, steel, plastic, asbestos, njll

Kunengqondo ukuthi eminyakeni yamuva esetshenziswa ngabantu abaningi ukuzedlula zonke plastic, njengoba le nto eyenziwe casings for imithombo abe nokuphila ngokwanele eside.

Kuyaphawuleka futhi ukusebenza high plastic.

Ngokwemvelo, efika engqondweni ukumelana ukugqwala, okungenzeka babe metal. Uma metal amapayipi amanzi agobhoze, iyona nomthelela omubi kakhulu kukhwalithi. Lapho usebenzisa i-ngamapayipi ensimbi emanzini ngokuvamile kubonakala ezingemnandi metallic ukunambitheka.

Ngaphezu kwalokho, tube bezinhlamvu plastic ukucwila kahle amanzi ngokwanele ukumelana ukungcola kanye tshe ukuba kwenze. Kanti liyakwazi ka withstanding imithwalo kahle eliphezulu (kufika ku 5 m), ukuqina kanye namandla kuyahluka. Kuyadingeka ukuba eceleni uqaphele okusezingeni eliphezulu ebusweni sangaphakathi ipayipi, ngaleyo ndlela kuncishiswe ukugeleza yayo ukumelana. Ngaphezu amathuba abo bonke it has ikhono lungisani ukufakwa kwamapayipi ka diameters ezincane.

Kufanele ikhumbule iqiniso lokuthi bezinhlamvu ipayipi ziyokwenziwa ngokuvumelana nazo zonke izinkambiso aqine. Kulokhu, ngisho ngeziphambeko ezincane azivumelekile. Naphezu ezihlukile ovality futhi amapayipi imingcele noma kunjalo akufanele lukwazi isethi ubukhulu nemingcele futhi odongeni ukujiya. Kuyefana nasendleleni misalignment yayo. Per imitha pipe esiphezulu misalignment kuvunyelwe elilodwa milimitha. Ngaphezu kwalokho, kuphela endabeni uma kuziwa ezinkulu-ububanzi amapayipi (phezu 89 mm), enziwe ngokunemba evamile.

Lapho esikhiqiza amapayipi ngokunemba Kwandiswa ngisho nomehluko omncane kukhona imingcele engamukeleki (esiphezulu 0.5 amamilimitha angu imitha ngalinye). Ekhuluma amapayipi ubukhulu ezincane (33,5-89 mm), esimweni kuqala kuvunyelwe ukuphambuka 0.7 mm, okwesibili - 0.3 mm.

ipayipi okunjalo ngihlaliswa emthonjeni ukuze kuvinjelwe fraying zomhlaba zokwakheka okuxekethile. Kunoma isiphi isimo, igemfe bezinhlamvu kufanele kwenzeke ukuba banamathele ezindongeni kahle ngokwalo. Ngakho-ke, ezihlukahlukene ezifana zokukhonjiswa ububanzi umkhiqizo osuphelile.

Ngokuvamile, phakathi bezinhlamvu ipayipi futhi odongeni Borehole ligcwele ukhonkolo. Kuyadingeka for nenkanuko edlulele baqinisa. Bese ngokuhamba kakade ezincane ubukhulu ipayipi. Bayadingeka ukuze imishini okwengeziwe noma Ukulisebenzisa ngokuqondile kanjena kahle. Kumele kuqashelwe futhi ukuthi tube kufanele uhlale ububanzi ezithile kanye isinqumo esithile. Kungenjalo, inqubo imishini kungaba ukuba yinkimbinkimbi kakhudlwana, okuyinto engathandeki kakhulu.
