What temperature can the mold single hair heat pipe withstand?
1. If the working temperature of the mold single hair heat pipe is about 100-300 degrees, the material is stainless steel 304.
2. If the working temperature of the mold single hair heat pipe is about 400-500 degrees, the material of stainless steel 321 can be selected.
3. If the working temperature of the mold single hair heat pipe is around 600-700 degrees, the pipe material should be stainless steel 310S.Whether the electric heating tube is corrosive
Heating weak acid and weak alkaline liquids: use corrosion-resistant stainless steel 316L.
Heating strong acid and strong alkaline liquids: Refer to the selection table of liquid electric heaters (stainless steel 316 + electrostatic anti-corrosion coating, generally any acid and alkaline liquids can withstand, the power per meter is generally set to about 2KW, slightly larger can.)Whether the electric heating tube is corrosive

How long does it take to heat 100L of water with an electric heating tube to increase the temperature by 10 degrees
The power of the electric heating tube required to heat 100kg of water from the initial water temperature of 10°C to 60°C in 60mins (3600s)?
Normal specific heat capacity of water: 4.2kJ/(kg·℃)
Heating temperature difference: 60-10=50℃
Required power (kw) = weight of water (kg) * temperature difference * specific heat capacity of water {kJ/(kg·℃)}/time (sec)
Substituting the formula to calculate the heat power=100*50*4.2/3600≈5.8KW
The power value of the required electric heating element can be obtained by dividing the different electric heating form by a certain thermal efficiency coefficient (such as 0.8-0.9).
