Kuzindikira ndi kuyesaMuyezo wa ASTMA53Chitoliro chiyenera kupambana mayeso ndi mayeso angapo monga kusanthula kapangidwe ka mankhwala, kusanthula kwa spectral, kuyesa katundu wa makina, kuyesa kupotoza, kuyesa kupindika, kuyesa kukhudzidwa, ndi kuzindikira zolakwika za radiographic.
Makhalidwe a ntchito ya chitoliro chachitsulo chosasunthika cha ASTMA53GR.B
1. Katundu wabwino kwambiri wama makina
Chitoliro chachitsulo chopanda msoko cha ASTMA53GR.B chili ndi mphamvu komanso kulimba kwambiri ndipo chimatha kupirira kupsinjika kwakukulu, kuonetsetsa kuti dongosolo la mapaipi ndi lotetezeka komanso lokhazikika. Kuphatikiza apo, zinthuzo zimakhalanso ndi kukana kuwonongeka komanso kukana kugwedezeka, zomwe zimatha kukulitsa moyo wa ntchito ya mapaipi.
2. Kukana dzimbiri mwamphamvu
Chitoliro cha ASTMA53GR.B chopanda chitsulo chopanda msoko chimapangidwa ndi chitsulo chapamwamba kwambiri cha kaboni. Pambuyo pokonza kutentha kwambiri, chimakhala ndi kukana dzimbiri ndipo chimatha kukana kuwonongeka kwa mankhwala monga ma acid ndi alkali, zomwe zimapangitsa kuti makina a mapaipi azigwira ntchito bwino kwa nthawi yayitali.
3. Kugwira ntchito bwino pokonza
Chitoliro chachitsulo chopanda msoko cha ASTMA53GR.B chili ndi kusinthasintha kwabwino, kudula bwino komanso pulasitiki, zomwe zimapangitsa kuti chikhale chosavuta kuchikonza ndikuchiyika. Kuphatikiza apo, zinthuzo zimakhalanso ndi kukana kutentha kwambiri komanso kotsika ndipo zimatha kugwira ntchito bwino m'malo ovuta.
Magawo ogwiritsira ntchito chitoliro chachitsulo chosasunthika cha ASTMA53GR.B
Chitoliro chachitsulo chosasunthika cha ASTMA53GR.B chimagwiritsidwa ntchito kwambiri m'magawo oyendera mafuta, gasi wachilengedwe, madzi, nthunzi ndi zina. Makamaka nthawi zina zomwe zimafunika kupirira kuthamanga kwambiri komanso kutentha kwambiri, chipangizochi ndi chisankho chofunikira kwambiri. Kuphatikiza apo, mapaipi achitsulo chosasunthika a ASTMA53GR.B amagwiritsidwanso ntchito kwambiri m'mafakitale a mankhwala, magetsi, zomangamanga ndi mafakitale ena kuti apereke zida zodalirika zamapaipi pazinthu zosiyanasiyana zotumizira madzi.
Kusankha ndi kusamalira chitoliro chachitsulo chopanda msoko cha ASTMA53GR.B
1. Malangizo osamala mukamagula
Mukamagula chitoliro chachitsulo chosasunthika cha ASTMA53GR.B, muyenera kulabadira mfundo zotsatirazi:
(1) Sankhani opanga nthawi zonse kuti muwonetsetse kuti zinthu zili bwino;
(2) Yang'anani ngati zofunikira, miyeso ndi makulidwe a khoma la chitoliro chachitsulo zikukwaniritsa zofunikira;
(3) Yang'anani mtundu wa pamwamba pa chitoliro chachitsulo kuti muwonetsetse kuti palibe zolakwika kapena kuwonongeka koonekeratu;
(4) Sankhani zipangizo zoyenera za chitoliro chachitsulo ndi zofunikira zake malinga ndi malo ogwiritsira ntchito ndi zofunikira zake.
2. Njira zodzitetezera pokonza
Mukamagwiritsa ntchito chitoliro chachitsulo chopanda msoko cha ASTMA53GR.B, muyenera kulabadira mfundo zotsatirazi:
(1) Kuyang'ana ndi kusamalira mapaipi nthawi zonse kuti mupeze ndikuthana ndi mavuto munthawi yake;
(2) Sungani mapaipi oyera komanso ouma kuti mapaipi asawonongeke mkati ndi kunja;
(3) Pa nthawi yoyendetsa ndi kukhazikitsa, chisamaliro chiyenera kuperekedwa pa kuteteza payipi kuti isagunde kapena kuwonongeka;
(4) Mapaipi achitsulo owonongeka ayenera kusinthidwa ndikukonzedwa nthawi yake kuti pakhale chitetezo ndi kukhazikika kwa dongosolo la mapaipi.
Mwachidule, chitoliro chachitsulo chosasunthika cha ASTMA53GR.B ndi chitoliro chokhala ndi magwiridwe antchito abwino kwambiri komanso malo ogwiritsidwa ntchito ambiri. Mukachigwiritsa ntchito, muyenera kusamala ndi nkhani zogula ndi kukonza kuti muwonetsetse kuti dongosolo la mapaipi ndi lotetezeka komanso lokhazikika. Ndi chitukuko chopitilira cha sayansi ndi ukadaulo, chitoliro chachitsulo chosasunthika cha ASTMA53GR.B chidzagwiritsidwa ntchito m'magawo ambiri, zomwe zimabweretsa zosavuta komanso zabwino pakupanga ndi moyo wa anthu.
