Ukupholisa ipayipi, lashukumisa (Standard)

Muva nje, ipayipi ukupholisa isibe zinc wandile, esesikhundleni plasticity okusezingeni eliphezulu futhi ehlukile anti-ukugqwala izakhiwo. imikhiqizo enjalo ingasetshenziswa ezihlukahlukene izimo, kodwa kubalulekile ukuba ukhethe kubo ngendlela efanele. I enamathela isetshenziswa therein aluzinc ehlanganisa 5% aluminium futhi 95% zinc.

Amapayipi Nezimo babe izinhlobonhlobo eziningi, kodwa zenziwa ngokuvumelana nesimo namazinga 14918-80 futhi ngezinga eliphezulu ukuzinza zamakhemikhali. Ukudayiswa kungabonwa ipayipi i ukupholisa izinhlelo, okuyinto kuhluke ultrahigh ukugqwala ukumelana kanye nezinguquko lokushisa, kulesi simo GOST 5632-72 isetshenziswa inqubo ukukhiqizwa.

Imininingwane Standard

Ukupholisa ipayipi , lashukumisa ungaba aboncamane nofana isiyingi cross-section, omhlophe webhola is rebated noma ashiselwe, futhi isiqondiso salo - ngqo noma Helical isiqondiso. Kukhona imikhiqizo ehlukahlukene okungatholakala ihlukaniswa ngokweminyaka yobunzima. Kodwa phatha ongaqhuba lapho lokushisa kuma kunqoba 80 ° C. Ukupholisa ipayipi, lashukumisa 100 mm - umugqa umkhiqizo oqala osayizi ububanzi. I enkulu ubukhulu umkhawulo 1250 mm. I ukushuba we ishidi esetshenziswa zingahluka kusuka 0.5 kuya 1.25 mm, kuyilapho ubude obuncane komkhiqizo kungenzeka elilingana 3 m, kodwa ubude obukhulu 25 amamitha. Athobele lezi kwezinkambiso imikhiqizo sanitary imithetho 2.04.05-91; 3.05.01-85.

Pipe nobudlova lashukumisa lingasetshenziswa kokuthutha nomswakama umoya 60% noma ngaphansi, izinga lokushisa kufanele angavuki ngenhla 80 ° C. Uma umkhiqizo ukuthi izosebenza ngaphansi kwezimo ezinjalo ukuthi ngesikhathi ukukhiqizwa steel ishidi isetshenziswa, okuyinto oluqanjwe indlela ugingqe abandayo. Uhlonze lwalo ungakwazi ukukwenza kufanele kulingane umkhawulo od 0.5 kuya 1 mm, indaba kumele uhambisane namazinga kahulumeni 14918-80. Ukuyisa umoya oshisayo ngaphezulu ezingeni lakhe lokushisa uyofinyelela 500 ° C, kumele imikhiqizo ekhethekile esetshenziswa afaneleka igesi zokuthutha.

I ukushuba kwezinkambiso sanitary imithetho

Ukupholisa ipayipi, lashukumisa 100 mm - liwumkhiqizo ubukhulu bayo, kodwa lokhu akulona isici kuphela ukuthi ichaza izici izinhlelo ezinjalo. Kubalulekile azi futhi mayelana ukushuba lapho ngoMthetho sanitary kwezinkambiso imithetho 11-33-75; 41-01-2003. Uma lo ububanzi we imbobo luyehluka in the ububanzi kufika ku 315 mm, ukushuba we ishidi esetshenziswayo 0.5 mm. Uma ipharamitha kuqala ngeke ifane kusuka 350 kuya ku-800 mm, umkhiqizo kufanele abe ukushuba odongeni 0.7 mm; lapho ubukhulu luyanda 900-1250 mm, udonga ukujiya kuyoba ulingana 0.9 mm. Udonga ukushuba 1.2 mm, uma ububanzi 1400-1600 mm.

ukumelana umlilo

Lashukumisa ipayipi ukuzwakalisa ungase ube athile isilinganiso umlilo ukumelana, lesi sici ichaza nesikhathi umkhiqizo ingahlala kusuka ekuqaleni bafudumale. Lokhu ipharamitha olushiwo imizuzu, lingatholakala ku uvule imbobo. Ukuze amapayipi asetshenziswe eliphezulu liphumele izakhiwo ukupholisa izinhlelo, umkhawulo ukumelana umlilo kuba imizuzu 90, ezakhiwe ezinjalo ogibele ophahleni.

Uma sikhuluma izindonga ephasishi umkhawulo engu-30. Lezi Amapayipi kukhona zero ekilasini ukumelana umlilo, kuyilapho namuhla kwaba namakilasi amahlanu athatha ezaziwayo. Kusukela zero kuze ngezinga yesihlanu komlilo ingozi uyanda. I tube kungenzeka eminye ivikelwe Ukwakheka ukumelana nomlilo. Ungenza ngokwakho, emva umthengi udinga ukuhlanza ebusweni elingaphandle umkhiqizo.

Ukwahlukaniswa air Amapayipi

Amapayipi Kuchazwe kungenzeka kwesigaba aboncamane nofana isiyingi. Imikhiqizo okuye kushiwo ukuwa last ku ukukhiya Kuvunguza futhi ashiselwe. Amashubhu nesigaba isiyingi kunenzuzo ngaphezulu kuqhathaniswa ne unxande cross kwesigaba amashubhu. Round nesisindo yobunzima ingasaphathwa ngenhla nokufaka izinhlelo ezifana letihambisana kulula.

umkhiqizo kukanxande oxhumene Flanges ngesikhathi sokufaka, kodwa sisebenzisa ubuchwepheshe ngaphandle Flanges. Izindawo ukusetshenziswa amapayipi unxande kukhona, emahhovisi, izikole nezindawo zezempilo. Amapayipi Round kukhona unxande ingasaphathwa, intengo 35% ephansi. Air ukusatshalaliswa kule mikhiqizo kuyinto iyunifomu, futhi izakhiwo umsindo-iyavuleka - ngenhla.

Izici ngci, Kuvunguza isilonda kanye nemikhiqizo longitudinally ashiselwe

I ukushisa namakhaza piping lokushisa akusho udedele, ke aqede okuvela ukufingqa ezindongeni, okungase kulimaze into. Lashukumisa umsebenzi ipayipi ngempela ezinomsindo, futhi khona nangokuvikela ungqimba yenza umsebenzi ukwahlukanisa umsindo. ungqimba enjalo ingenziwa yezimbiwa fibre wazizwa, polyurethane, kanye elastomers Foam.

Lashukumisa ipayipi ukuzwakalisa (125) wenziwe Kuvunguza iribhoni ezisontekile kuveza Kuvunguza, it kwandisa amandla futhi rigidity. Ubude imikhiqizo enjalo ngokuvamile elilingana 3 m. I ezivuzayo imbobo inombolo sakugcina amalunga, okusho ukuthi uhlelo has a yobunzima ephakeme. amapayipi eziphothene ishibhile kuqhathaniswa Kuvunguza, ngoba enza yabo akudingekile ukulungiselela lashukumisa steel ishidi. Ubude amapayipi longitudinal uqobo 125 m, njengoba umthetho, basuke uthenge ukufakwa ngaphandle.

Izindleko Amapayipi isiyingi ngensimbi lashukumisa, kuncike ubukhulu

Ukupholisa ipayipi, lashukumisa 200 mm - lena umkhiqizo ukuphunyuka, okuyinto kuyodingeka bakhokhe ruble 755. Uma ubukhulu luyanda 1250 mm, bese intengo kuyoba ulingana ruble 7500. yileyo naleyo ingamashekeli. Ukuze imikhiqizo ububanzi kulencane 100 mm kufanele ukhokhe ruble 400. sibalo Isilinganiso nge ububanzi 500 mm izindleko umthengi ruble 2800.
