Tha BT4 air a chomharrachadh mar bhuidheann teòthachd Clas B, far nach eil an teòthachd uachdar as àirde airson innealan ìre T4 nas àirde na 135 ° C. Tha ìre dìon-spreadhaidh Clas C aig CT4, coimeas ri BT4, and is suitable for environments with hazardous gases such as hydrogen and acetylene, maintaining a maximum surface temperature of 135°C.
Scope of Use
BT4 is suitable for common gases including methane, ethane, peatrail, agus haidridean sulfide.
CT4 encompasses a broader range of less common spreadhach gasaichean, such as hydrogen and water gas at the CT1 level, acetylene at the CT2 level, and carbon disulfide at the CT4 level.
