Bomba la chuma la SCH40 GI lenye ncha zenye miiba linamaanisha bomba la chuma linalotengenezwa ili kukidhi kiwango cha SCH40 cha unene wa ukuta na limetengenezwa kwa chuma cha mabati. "GI" inawakilisha "chuma cha mabati" ikionyesha kwamba bomba limefunikwa na safu ya zinki ili kuilinda kutokana na kutu.
Neno "ncha zilizopasuka" linaonyesha kwamba ncha za bomba zimeundwa kwa mifereji ili kurahisisha usakinishaji wa viunganishi au vifaa vya mitambo. Ncha zilizopasuka hutumiwa kwa kawaida katika mifumo ya ulinzi wa moto, mifumo ya HVAC, na matumizi mengine ambapo miunganisho ya haraka na salama inahitajika.
