20G high pressure boiler tube implementation standardGB5310-2008chiyero chekushandiswa, chinoshandiswa kugadzira bhaira remvura rine simba rakawanda uye rinorema kupfuura simba rebhaira rine simbi yekabhoni yepamusoro, simbi yesimbi yesimbi isina tsvina uye bhaira resimbi isina tsvina isina tsvina. Bhaira resimbi risina simba rebhaira rine simba rakawanda imhando yebhaira, nekuti bhaira re20G rine simba rakawanda rinowanzo shandiswa mumamiriro ekupisa akakwira uye ekumanikidzwa kwakakwira, bhaira iri pasi pesimba regesi inopisa uye utsi hwemvura, oxidation uye ngura zvichaitika. Pipe yesimbi inodiwa kuti ive nesimba rakasimba, inodzivirira ngura zvakanyanya uye kugadzikana kwakanaka kwe microstructure. Bhaira remvura rine simba rakawanda rinonyanya kushandiswa kugadzira bhaira remvura ine simba rakawanda uye superheater, bhaira reheater, bhaira, bhaira remvura, bhaira guru remvura, nezvimwewo. Mukushanda kwebhaira remvura risina simba rebhaira, mvura yakatarwa inofanira kuchengetwa mubhaira, kumanikidzwa hakufanirwe kudarika kumanikidzwa kwebhaira, vashandi vebhaira vanofanirwa kugara vachitarisa gauge yekumanikidzwa kwemhepo. Kana bhaira razara nemvura, rinofanira kusvinwa nemvura nenguva kuti rimire kunyorova pamwe chete uye kudzoreredza huwandu hwemvura. Mushure mekunge vira ramiswa, mushure mekunge mvura yatonhodzwa kwenguva refu kusvika pasi pemadhigirii makumi manomwe, mvura yevira inogona kuburitswa, uye mvura yemuboiler yekurapa nemakemikari inogona kushandiswa mushure mekunge mambure adzimwa. Boiler ine simbi isina musono inoshandiswa zvikuru kugadzira machubhu emuboiler ane pressure yakakwira uye ultra high pressure superheater, reheater tube, pombi, main steam pipe, nezvimwewo. Rudzi rweboiler tube rwunoenderana nekushanda kwekupisa kwakanyanya rwakakamurwa kuita machubhu emuboiler akajairika uye machubhu emuboiler ane pressure yakakwira.
