Kauv Pipe (ssaw steel yeeb nkab): los ntawm sawb los ntawm yob txoj kev tshuab, folding kauv kev taw qhia, thiab ces ob-sided submerged arc vuam yog ua los ntawm ib tug capacitor. Kauv welded steel yeeb nkab txheej txheem ntau lawm, nws muaj feem xyuam rau feem ntau, xws li vuam thiab sab tsis ncaj ncees lawm. Txawm li cas los xij, nyob rau hauv cov xwm txheej no tshwm sim Chlamydia yog qhov nyuaj tshaj plaws los ua tus tswv kauv hlau taub qab vuam.

Lub npe hu ua trachoma: tias cov txheej txheem vuam nyob rau sab hauv qhov chaw ntawm qhov vuam los yog vuam, tsis tau muaj kev nkag mus zoo ntawm cov khoom los yog npuas, nrog rau cov duab ntawm cov xuab zeb hauv qhov chaw ntawm qhov vuam. Qhov laj thawj rau trachoma yog cov hauv qab no:
1, cov khoom siv hluav taws xob vuam thaum lub sij hawm tam sim no me me dhau lawm, lub capacitor luv dhau, lub capacitor tsis tau ua tiav tag nrho thaum vuam cov vuam nto tau hardened, yog li muaj kev nkag mus ntawm cov xuab zeb lossis tsis npuas.
2, scimitar tune rau hauv lub strip-shaped curvature ntawm lub sij hawm tsis muaj pob tw zoo, pob tw strip tsis phim raws nraim, muaj ntau dhau ntawm qhov sib txawv ntawm lub pob tw.
3, lub pob tw welded steel thaum ob sab tsis tau tshem tawm ntawm ntug ntawm lub sawb xeb lossis nplai.
4, tsis muaj kev tu ncua sij hawm ntawm cov khoom siv los ntxuav. Workbench plua plav lossis av, yuam kev poob rau hauv qhov sib txawv ntawm lub pob tw vuam ntawm cov hlau.
5, kev khiav hauj lwm kub yog tsawg dhau los yog ntub dej rhiav, uas cuam tshuam rau qhov kub thiab txias ntawm vuam cov ntsiab lus.
