Butt-Weld Elbo em i wanpela paip fiting ol i save yusim planti taim long paiping sistem, ol i save yusim long senisim daireksen bilong wara. Ol samting bilong en, ol teknikel samting na wok bilong glasim ol samting i mas bihainim ol standet i stret.
Ol samting bilong weldim elbo em i as bilong ol nupela samting na i save mekim bikpela wok long promotim na helpim wok bilong kamapim ol samting bilong hai-end. Namel long ol nupela samting, ol samting i save kamap inap olsem 85%. Taim ol i yusim ol elbo bilong butt-}welding, ol i mas stap klin olgeta taim na ol tred bilong transmisin i save gre gut long olgeta taim. Taim ol i painimaut pinis wanpela asua, ol i mas stopim masin kwiktaim bilong luksave long as bilong asua. Ol i save yusim ol elbo bilong presim na weldim long konektim tupela paip i gat wankain nominal diamita na tanim ol paip long 90 digri.
Ol samting bilong wokim
Ol i mas givim wanpela 'matirile catetific' (MTC) wantaim ol kemikal, ol samting bilong wokim ol samting (strong bilong tensen, strong bilong kaikai), na ol narapela samting.
Ol samting bilong pepa/paip samting i mas bihainim ol standet olsem ASTM A105 (ol i bin wokim ain) na ASTM A106 (paip ol i weldim).
