This means that the flames themselves come into contact with other fuel sources which also catch fire. It can contain tiny solid particles, gas particles, and even minute fluid particles (which are most likely to be water). Since the washover pipe is relatively thin-walled and large in diameter, and may be prone to sticking itself, the washover operation is usually reserved as a measure of last resort before abandoning the fish altogether. How do we protect the steel structure from fire? In nonbarrier situations it may be bedrock cliffs, glacial drift, or even man-made structures such as seawalls. So, though it may seem counterintuitive - smoke is a real fire hazard and . Email: hello@cpd.email Meaning of washover.
