Doko loyera la fyuluta lizikhala pansi, ndipo padzakhala malo okwanira ogwira ntchito pansi pake; tsinde la valavu la valavu ya pachipata lidzakhala lowongoka komanso losavuta kutsegula ndi kutseka
Ntchito: pamwamba pakuwunika kudzakhala koyenera komanso kokhazikika.

Kuyika kwa mita ya 2
Kukhazikitsa mita yamadzi: kukhazikitsa kwa mita ya projekiti kumaphatikizapo mita yayikulu yamadzi ndi mita yogawa madzi yomwe wogwiritsa ntchito amagwiritsa ntchito. Mita yayikulu yamadzi imayikidwa mu chomera chamadzi
Pa chitoliro chachikulu, mita yogawa madzi imayikidwa patsogolo pa chitseko cha wogwiritsa ntchito. Mukakhazikitsa mita yamadzi, wogwiritsa ntchitoyo azisamalira momwe angapangire mita kuti madzi alowe mofanana ndi malangizo omwe amapezeka pamamita amadzi, ndipo mita yazoyeserera idzayikidwa mopingasa. Kuyika mozungulira sikuloledwa. Mamita ozungulira amadzi amatha kukhazikitsidwa mopingasa, mozungulira kapena mozungulira. Ikayikidwa mozungulira kapena mopingasa, mayendedwe amadzi ayenera kukhala ochokera pansi mpaka pamwamba. Chipolopolo chakunja cha mita yamadzi yakunyumba chizikhala 1-3cm kutali ndi khoma. Ngati gawo lolunjika la chitoliro lisanachitike komanso pambuyo pake mita yamadzi ipitilira 30cm, liyenera kupindika
Kuyika khoma. Pali mtunda wina pakati pa mita yamadzi ndi valavu I, ndipo kutalika kwake ndikokulirapo kuposa kapena kofanana ndi maulendo 8-10 a chitoliro.

Unsembe 3.Flange kugwirizana
Chongani ngati m'mphepete yotukuka ya flange lathyathyathya kuwotcherera ndi mosabisa ndi poyambira uli wathunthu, ndi flange zosalongosoka sati ntchito;
Pazitsulo zachitsulo zikasonkhanitsidwa ndi chitoliro, dzenje pakati pakatundu wakunja wa chitoliro ndi mkati mwake mwa flange silipitilira 2mm; flange ikamalumikizidwa, chitolirocho chimalowetsedwa kupitirira theka la makulidwe a flange, ndipo mawonekedwewo adzafufuzidwa mbali ziwiri ndi mbali ya 90 ° wina ndi mnzake, ndipo perpendicularity izikhala yochepera 0.5mm ; cholumikizira cha flange chimamangirizidwa ndi njira ziwiri zowotchera, ndipo ndodo yowotcherera ndi e4315, yomwe imawumitsidwa pasadakhale ngati pakufunika. Zitsulo zotsekemera zizichotsedwa pambuyo pomaliza china chilichonse, ndipo mawonekedwe ake akuyenera kuwunikidwa mosamala. Magawo osayenerera ayenera kuchotsedwa kuti akonzedwe; kuwotcherera kwa flange kumachitika pambuyo pomaliza mbali yakunja, ndipo kutalika kwakatundu kotsekera sikungapitirire kumtunda kosindikiza; flange fillet weld idzayang'aniridwa ndi maginito a 100% kapena kuyendera kolowera, ndipo mtunduwo udzakwaniritsa zofunikira za kalasi yachiwiri ya jb4730-2005 muyeso woyeserera wopanda ziwiya zapanikizika; The ulusi ulusi wa flange adzaonetsetsa mayikidwe a mabowo wononga, ndi awiri a mabowo wononga ndi akapichi adzakhala yofananira, kutalika kwa akapichi kulumikiza adzakhala yemweyo, mtedza adzakhala mbali yomweyo, ndi mtedza adzakhala anawonjezera pambuyo mabotolo ndi omangika mabatani awiri; gasket yosindikiza idzakonzedwa ndi gasket wa Bunan flange; pambuyo pa kukhazikitsa kwazitsulo, zida zachitsulo zowonekera zidzakombedwaMalaya awiri amakala phula epoxy.
