Ndi Mulingo Uti Wotsimikizira Kuphulika Ndi Wapamwamba, BT4 kapena CT6

Mtundu wa BT4 umayikidwa pansi pa Kuphulika kwa Gulu B lokhala ndi kutentha kwa T4, stipulating that the equipment’s surface temperature cannot exceed 135°C.

Mosiyana, mtundu wa CT6 uli ndi Class C-proof-proof rating, covering the requirements of BT4 and applicable to zones with dangerous gases like hydrogen and acetylene. T6 equipment must maintain a surface temperature no higher than 85°C.

Malinga ndi kutentha Magulu, T6 represents the highest safety level, suggesting that a lower equipment surface temperature is preferable.

Zotsatira zake, CT6 possesses a superior explosion-proof classification.
