The design calculation of the tubular heating element is generally carried out in the following three steps:
1. Calculate the required power from the initial temperature to the set temperature for a specified period of time.
2. Calculate the actual required temperature to maintain the temperature while maintaining the temperature of the medium.
3. According to the above two calculation results, select the type and quantity of the heater. The total power takes the maximum of the above two powers and considers the 1.2 coefficient.
As a salesperson of heating element, we deal with customers who need heating pipes in various industries every day. One of the first concerns many customers have is the price of the heating tube. In fact, no matter who you are, buying the same thing and paying attention to the price is a very practical problem. However, for our heating pipe industry, it is unscientific to directly compare the price of the heating pipe. Since the heating tube is a non-standard customized product, it is impossible to quote the customer for any parameters that are not clear at the first time. Therefore, all customers who purchase heating pipes pay attention to it. If you do not ask you when purchasing the heating pipe, you will be given a price directly. There is no doubt that such heating pipe sales personnel are unprofessional. Therefore, customers who purchase heating tubes should be more patient when purchasing consultations. This is definitely helpful for you to choose a heating tube suitable for your working environment.
To know the price of the heating tube, we have to figure out the following parameters:
First of all, we need to understand the working environment of the heating pipe: is it heating liquid or air drying?
Secondly, we need to know whether the customer has its own design drawings. If there is, we can directly see whether the drawing design is suitable for the working environment according to the customer's drawings. If there is no design drawing, the customer can provide us with a rough outline picture. We will help you design the heating tube size according to your pictures and your installation space.
Again, we need to understand the choice of materials, the choice of materials also has a great impact on the price of the heating pipe. From the most common material: stainless steel, stainless steel is divided into SUS201# 304 # 310 # 316 # 321#, etc. These materials can be selected according to different working environments, so the customer is consulting a number of heating pipe manufacturers. The first thing to do is to figure out what kind of material you need.
Reference: 1. Correctly select the external material of the electric heating tube. 2. Correctly select the internal material of the electric heating tube.
Finally, we have to help customers choose the wall thickness of the heating tube. Different wall thicknesses are selected according to different working environments. For relatively large pressure, thick-walled thick heating pipes are used. Different wall thicknesses also directly affect the price of the heating tube.
Therefore, we must first understand some of the above basic parameters, we have to calculate a rough price, it is recommended that customers do not blindly pursue the lowest price, but choose the most suitable heating pipe and the most cost-effective heating pipe manufacturer. Quote.
