Shenhai Explosion-Proof
Te tapea nei na tuhaa e piti nei i te hoê tatuhaaraa T4 anuvera, no reira, e tupu te taa - ê - raa i rotopu ia Zone A e Zone B. E mea rahi a'e te mau haamau'araa i ni'a i te BT4 i to te AT4.
| Te huru o te taata | Te tatuhaaraa i te mau m | Te mau mana'o tauturu no te haapiiraa | Te ito o te ore e nehenehe e faaohipahia |
|---|---|---|---|
| I raro a'e i te apoo | I | Methane | 0.280MJ |
| Te mau fare hamaniraa tauihaa i rapaeau mai i te apoo | IIA | Propane | 0.180MJ |
| IIB | Ethylene | 0.060MJ | |
| IIC | Hydrogen | 0.019MJ |
Te vai nei te hoê taa-ê-raa rahi i rotopu i te haapiiraa ii.a e te piha haapiiraa ii.b. Class ii.b, te ti'araa teitei a'e, is typically designated for fuels like Te mau mana'o tauturu no te, Te mau mana'o tauturu no te, and crude oil; Class ⅱa, i te tahi pae, applies to standard explosion-proof areas, such as for propylene.
It primarily depends on whether a substance falls under Class ⅱa or Class ⅱb. Equipment rated for Class ⅱa can be utilized in Class ⅱa environments; Te mau mana'o tauturu no te, Class ⅱb environments cannot employ Class ⅱa equipment.
