1, ua ntej qhov kev sib txuas ntawm qhov txuas, cov yeeb nkab thiab yeeb nkab yuav tsum raug kuaj xyuas raws li cov qauv tsim, thiab yuav tsum nyob rau hauv qhov kev tsim kho qhov muag pom, raws li qhov yuav tsum tau siv. Cov khoom tseem ceeb muaj xws li cov qib siab, qhov zoo ntawm sab nraud, kev sib thooj, sib luag ntawm cov ntaub ntawv, thiab lwm yam.
2. Cov khoom siv cua sov tshwj xeeb yuav tsum tau txais los ntawm ntau hom ntawv sib txawv, thiab tsis qhib hlawv taws cua kub thiab fittings yuav tsum siv.
3, kev siv txoj hlua txuas nrog lub raj xa dej, nws yog qhov tsim nyog siv tib hom khoom yeeb nkab thiab fittings, rau cov khoom zoo sib xws yuav tsum dhau qhov kev xeem, tus neeg tsim nyog muaj peev xwm nqa tau.
4, yeeb nkab thiab cov yeeb nkab yuav tsum muab tso rau hauv qhov chaw tom qab siv qee lub sij hawm mus txuas, kom cov yeeb nkab thiab cov yeeb nkab tsis muaj xwm txheej
5, hauv kev nyab xeeb txias (hauv qab - - 5 degrees) thiab cua hlob zoo rau kev sib txuas, yuav tsum siv kev ntsuas los tiv thaiv txoj kev sib txuas.
6, qhov txuas kav raj xa dej yuav tsum huv, txhua hnub thaum lub tshuab no yuav tsum yog ib ntus ntsaws ruaj ruaj, tiv thaiv kom txhob muaj khib nyiab rau hauv lub raj.
7, tom qab kev sib txuas ntawm lub raj xa dej yuav tsum yog qhov kev tshuaj ntsuam xyuas, tsis tsim nyog ua haujlwm tam sim ntawd. Yog thawj txheej ntawm fused fittings hauv yeeb nkab, thiab siv cov ciaj ciam ntawm qhov vuam tshuab raws li cov cai ntawm lub sijhawm (lub sij hawm thiab qhov hluav taws xob) mus rau fais fab tua hluav taws xob yog lub zog, lub sab nraud ntawm sab hauv ntawm cov yeeb nkab thiab kab hluav taws xob melting yeeb nkab fais cua kub hlau nyob hauv txoj hlua khi, tom qab cua txias thiab fittings uas fused ua ke. Nws tus cwj pwm yog tias txoj kev txuas yog yooj yim thiab ceev, kev sib koom tes zoo zoo, qhov tseem ceeb tshaj yog cuam tshuam me me, tab sis tus nqi hluav taws xob melting yeeb nkab fittings yog ob peb zaug ntawm ntau zaus cov yeeb nkab fittings (lub me me caliber yog , qhov loj dua qhov txawv),
