グラフから想定されることを回答いたします。
圧力の測定間隔（何秒置きの測定）が不明ですが、
グラフを見る限りでは瞬間的な最大圧力は50kg/cm2程度なので、問題ないと思われます。
また、詳しい運転条件がわかりませんが、16：57あたりから圧力が下がっていることに関しては、
流量を増やした直後はエレメントの温度が低かったため圧損が高かったが、樹脂の発熱などにより、
だんだんとエレメントが温められて圧損が下がっていたと考えれば、ありえると考えます。

I will answer referring to the graph.
Although pressure measurement interval (How often in minute it is measured.) is not clear as long as I can see in the graph, impetus maximum pressure is 50kg/cm2, it seems no problem.
Also, I cannot get detailed operation condition, regarding the pressure is down at 16:57, just after increasing its flow, as the element's temperature was low, the pressure was high, but by resin's heat, the element is gradually warmed up and its pressure loss was lowered, it seems it happened.

I will answer by what I can see from graph.
I do not know interval of measuring pressure (measuring by second).
But as long as I see the graph, maximum pressure at an instant is 50 kilograms /cm2. For this reason, we do not have a problem.
I do not know condition of operation in detail. But regard the fact that pressure has been going down from at around 16:57, it is possible if we think as follows. The pressure was high since temperature of element was low immediately after increasing volume of flow, but the element had been warmed gradually due to generation of heat, which caused pressure loss lower.

I will answer based on the assumption from graph.
Measurement period (measurement was every how many minutes) of pressure is unknown but as long as I see the graph, maximum pressure is about 50kg/cm2 and it should be no problem.
Also I don't know the detailed running condition, but as for pressure start decreasing from around 16：57, it could be happen if element temperature was low straight after current amount was increased, and pressure damage was high, or due to the heat generation of resign etc,element was gradually warmed up and pressure damage was decreased.
