Method for storing electric heating tubes

Electric heating tubes are things that we often use in our daily lives, but we rarely come into contact with them. For the use of electric heating tubes, read the relevant instructions carefully before installation and use to avoid damage. In fact, there are many types of electric heating pipes, mainly divided into single head stainless steel electric heating pipes, electronic equipment, double head stainless steel electric heating pipes, far infrared electric heating pipes, heat sink stainless steel electric heating pipes, seamless steel type stainless steel electric heating pipes, air duct heat sink electric heating pipes, heat sink electric heating pipes, mold temperature machine electric heating pipes, heat sink electric heating pipes, vulcanization machine electric heating pipes, ceramic electric heating pipes, quartz heating pipes, copper heating pipes, Annealed stainless steel electric heating tube, 304 stainless steel electric heating tube, iron heating tube, high-temperature stainless steel electric heating tube U-shaped electric heating tube.

For some electric heating pipes stored in a dry warehouse, if the surface is damp due to long-term storage, a megohmmeter should be used to measure the insulation resistance. If it is less than 1 megohm/500 volts, the electric heating tube should be placed in a 200 degree drying oven for drying. For electric heating pipes that have been used for a long time, if thick pipe scale and oil scale accumulate on their surface, they should be regularly removed, otherwise it will reduce the heat transfer performance of the electric heating pipe and cause damage to the surface heat load exceeding the rated allowable value.

For ordinary people, the calculation method of using electric heating tubes may not be necessary. But for friends who want to know some formulas, let's take a look at the formula: the power required for initial heating, KW=(C1M1T+C2M2T) ÷ 864/P+P/2

In the formula, C1C2 represents the specific heat of the container and medium (Kcal/Kg ℃), respectively

M1M2 represents the mass of the container and medium, in kilograms

T is the difference between the required temperature and the initial temperature (℃)

H is the time required to heat the initial temperature to the set temperature (h)

Heat dissipation of container at final temperature P (Kw)

Perhaps everyone feels that we cannot use these complex formulas, so when choosing electric heating tubes, we only need to find a qualified manufacturer. Choosing a high-quality and affordable electric heating tube is what we all hope for, but we must not give up safe use for the sake of affordability.
