Ama-diameter yamapayipi amanzi: i-GOST. Amapayipi amanzi epulasitiki nasensimbi

Ngesikhathi ehlanganyela ekwakhiweni noma ekulungisweni kwamapayipi amanzi, omunye kufanele ahlaziye emkhakheni wezimpawu zepayipi. Emva kwakho konke, kuye ngezimo ezikhona, kubalulekile ukuthola olunye noma olunye uhlobo lwemikhiqizo enjalo. являются одной из самых важных их характеристик. Ububanzi bamapayipi amanzi ngenye yezici ezibaluleke kakhulu. Ngakho-ke, kunakekelwa okuningi kule nkinga.

Kunezinhlobo eziningana eziyinhloko zamapayipi amanzi. Kuye eqenjini lapho umkhiqizo ngamunye ungowakhe, kunamasayizi athile. Yiziphi amamitha, indlela yokuzikhethela, okufanele zicatshangelwe ngaphambi kokuthenga nokufaka uhlelo.

Izici ezijwayelekile

Ukuhlomisa uhlelo lwamanzi ngaphakathi kwezakhiwo, izitsha zensimbi, amapulasitiki kanye namapayipi ahlangene. Kuzohlukahluka ngalunye kunesilinganiso saso. можно измерять в дюймах или в миллиметрах. Ububanzi bamapayipi amanzi angalinganiswa ngamasentimitha noma ngamamitha. Ukukhethwa kokubala kubhekene nezici zomkhiqizo.

Ukuze ulungise ubukhulu bepayipi yamanzi, sebenzisa izinkomba ezintathu eziyinhloko. Lokhu kufaka phakathi ububanzi obungaphakathi nangaphakathi, kanye nobukhulu bezindonga.

Ekhulwini leminyaka elidlule, lapho kuhlala ezindlini zezakhamuzi ezejwayelekile kwakukhona kuphela amapayipi ensimbi kuphela, isimiso esiyingqayizivele sokubala ubukhulu bokuxhumana sasungulwa. это 12,7) могли составлять, например, полдюйма. Ububanzi bangaphakathi bamapayipi amanzi (in mm ngu-12.7) kungaba, isibonelo, isigamu intshi. Kodwa ngesikhathi esifanayo usayizi wangaphandle nomcibisholo ufinyelele okungaba ngu-21 mm. Ngakho-ke, ukubhala intambo eboniswe ukuthi yi-intshi yama-intshi.

Amapayipi ensimbi nezethusi

указывается в маркировке по размеру снаружи, а также толщине стенки. Ububanzi bamapayipi amanzi ensimbi kuboniswa ekumakeleni ubukhulu bezingaphandle, kanye nobukhulu bodonga. Isibonelo, umkhiqizo we-60x3 wuxhumano olunengxenye yangaphandle engaba ngu-60 mm nobukhulu bodonga obu-3 mm. Ingxenye yangaphakathi izoba ngu 54 mm. Kukhona nesistimu ye-metric elula. Ukumaka kwawo, isibonelo M14, kubonisa ukuthi ipayipi ine-diameter yangaphandle ka-14 mm.

Kodwa ngemikhiqizo yethusi, isistimu yokulinganisa inch isetshenziswa. Futhi ukumaka kwenziwa ngokucabangela ububanzi obungaphandle. Kulesi simo, kunolwazi oluthile lwamapayipi wezethusi kumshini we-metric. Isibonelo, i-intshi engu-1 ilingana no-25.4 mm.

Uma kudingekile ukuthi usebenze ngesikhathi sokusebenza ukuxhuma ipayipi yensimbi ngezinhlobo zepulasitiki, kusetshenziselwa ukukhishwa okukhethekile. Kungase kube nezinkinga. Ukuze ukhethe usayizi wabo, udinga ukunaka ukumaka kwepayipi yensimbi.

Amapayipi eplastiki

Ezinye izindlela eziningi zokumaketha zinamapayipi amanzi eplastiki . которых имеет номер 18599-2001, имеют большой диапазон. I-Diameter, i-GOST yayo inombhalo 18599-2001, inebanga elikhulu. Kuthengiswa kukhona amapayipi amanzi ane-cross-section kusuka 20 kuya 1200 mm. Ngokuvamile, ukhetho luwela emikhiqizweni enjenge-PE 80 noma engu-100.

Amapayipi PE 80 aklanyelwe amanzi okushisa (0-40 ° C). Zigwetshiwe abamnyama ngesigcawu eside sombala we-blue tones. Ububanzi bangaphakathi bokuxhumana okusetshenziselwa kakhulu kungasuka ku-16 kuya ku-110 mm. Inkinga yabo yokusebenza, kuye ngokuthi yiqembu, ivela ku-0.32 kuya ku-2 MPa.

I-PE 100 ingumshini wokucindezela. Yenziwa yi-extrusion. Lezi zinhlobonhlobo zisetshenziselwa izinhlelo zangaphandle zokuhlinzeka kwamanzi abandayo.

Amapayipi e-polyethylene athengiswa ngokudayiswa ngokumaka, okukhombisa uhlobo lomkhiqizo, injongo yalo, ubukhulu bodonga nobubanzi, kanye nokubeka uphawu kwe-GOST okudalwe ngalo mkhiqizo.

Amapayipi e-polypropylene nama-PVC

в продаже представлена с маркировкой толщины стенки. Ipayipu yamanzi epulasitiki idayiswa ngokubhala nge-thickness. Futhi, abakhiqizi babonisa ububanzi bayo bangaphandle. Lena enye yezinhlobo ezintsha zamapayipi amanzi. Ngakho-ke, zakhiwa ngokuhambisana namazinga (isibonelo, 4200 / DIN noma i-2458 ISO, njll).

Kumaphayiphi anjalo kufanele abe khona uphawu lokuhweba nesitifiketi sokwaziswa. Kunezinhlobo eziningana ze-polypropylene zokuxhumana, kuye ngokuthi ingcindezi yokuqokwa.

Usayizi wangaphandle wezinhlobo zepayipi ezethuliwe zingaboniswa ngamasentimitha noma amanani we-metric. Ukukhethwa kwesistimu kuncike kumakhi.

Amapayipi e-PVC akhethwe ngendlela efanayo nezinhlobo ze-polypropylene. Kuzo zombili izinhlobo zemikhiqizo, ubukhulu abuhambisani namanani avamile we-metric system.

Dlulisa amasentimitha kuya kuma-millimeters

которой указан в дюймах, можно перевести в миллиметры. Ipayipi yamanzi, ebangeni layo langaphandle likhonjiswa ngamasentimitha, lingaguqulelwa libe yizigidigidi. Inqubo kufanele icatshangelwe ngesibonelo. Ake sithi kuthengwa ithubhu enobubanzi obuyi-1 intshi. Ububanzi bayo obungaphandle uma kulinganiswa nombusi cishe buyi-25.4 mm.

Kodwa ngokukhethwa kokufakelwa udinga ukwazi inkomba yochungechunge. Uma ucabangela imingcele yezobuchwepheshe yochungechunge lwama-cylindrical ngamapayipi, ububanzi obungaphandle kwalesi sibonakaliso buzolingana no-33.2 mm. Lokhu kungenxa yezici ezikhethekile zokukhiqiza. Intambo inqunywa ngaphandle kwezokuxhumana. Ngakho-ke, ukuhlobana kwalo nobubanzi bangaphakathi kunalokho kungabonakali. Ngokwezibalo, ubukhulu bodonga obuphindwe kabili bunwetshwa ku-25.4 mm.

Ukukhethwa kwamamitha

являются важной характеристикой. Amapayipi wamapayipi amanzi ayingxenye ebalulekile. Lokhu kungenxa ye-bandwidth yokuxhumana. Kuncike ekutheni, amanzi angakanani azodlula ohlelweni ngalunye isikhathi. Umahluko omkhulu kunomahluko ophikisayo kuwo, izinga elikhulu lokugeleza ketshezi.

Amasu akhethekile wokubala umkhawulokudonsa wokuxhumana. Amatafula akhethekile asetshenzisiwe. Ngenxa yokuthi isibalo esinjalo sinzima kakhulu, cishe asisetshenziselwa ukuhlomisa uhlelo ngaphakathi kwendawo.

Ngokuvamile ama-repairmen wezisebenzi nama-house aqondiswa ukulula. Ukwenza ukusatshalaliswa kwamanzi ngaphakathi kwefulethi, ukuthengwa kwamapayipi ½ amasentimitha. Uma ufaka i-riser, ukuxhumana nesigaba esinqunyiwe se-¾ noma 1 intshi kuyadingeka.

Ukuxhomeka kokuphakama kokubonakalayo

может стыковаться со стальными коммуникациями. Njengoba kukhulunywe ngenhla, ipayipi yamanzi epulasitiki ingaxhunyaniswa nensimbi yokuxhumana. Ukuze uthole ukufakwa okulungile, udinga ukuthenga izinhlobo zabo ezijwayelekile. Uma zakhiwa, ubukhulu bombhobho bucatshangelwa, ngokuya kwento. Ngakho-ke, akufanele kube khona ubunzima kule nqubo.

Kodwa lapha kushintsha ithusi, amapayipi aluminium, kuyadingeka ukuba ungene embuzweni wemigomo yabo. Ubukhulu bemikhiqizo enjalo kuboniswa ohlelweni lwe-metric. Futhi, ngenkathi uzijoyina ngezinhlobo zepulasitiki, kufanele ucabange kokubili ububanzi obungaphakathi nangaphandle, kanye nobukhulu bawo obuyizinkulungwane.

Ngakho-ke, ukuze uthole i-wiring yangaphakathi, ungathenga imikhiqizo ngobubanzi obuyi-10 no-15 mm, futhi ukuphakama kungama-20 no-25 mm. Kumele kuqashelwe ukuthi ipulasitiki yeplastiki ene-½ "ingxenye yesigcawu ingaba nosayizi wangaphakathi ka-11-13 mm.

, можно правильно подобрать изделия для системы коммуникаций. Njengoba ujwayele isici esinjengamamitha emipayipi yamanzi , kungenzeka ukhethe imikhiqizo efanele yesistimu yokuxhumana.
