1. Straight Type Electric Tubular Heating Elements rated power deviation. According to the provisions of 4.3.2 of JB/T 2379-1993, under the condition of sufficient heat, the deviation of the rated power of the component shall not exceed the following specified range: ±10% for components with rated power less than or equal to 100W; Components larger than 100W are +5% to -10% or 10W, whichever is greater.


2. The operating voltage of the Straight Type Electric Tubular Heating Elements is not enough. According to the calculation formula, it can be known that the working voltage is proportional to the power when the Electric Industrial Spiral Coil Tubular Heater Element resistance value is fixed. If the actual operating voltage is lower than the rated voltage, then the actual operating power is definitely lower than the rated power.


3. In the production process of the Electric Industrial Spiral Coil Tubular Heater Element, in order to ensure the compaction of the insulating magnesium powder in Electric Industrial Spiral Coil Heating Element, a processing process of shrinking the pipe is required (see the Electric Industrial Spiral Coil Heating Element production process for details). In the process of shrinking the tube, the heating wire in the Stainless Steel 304 Industrial Tubular Heateris squeezed and becomes thicker, so that the resistance value becomes smaller and the power becomes larger. Therefore, in the production, the resistance value of the heating wire is increased according to the instrument setting and production experience, so that the Stainless Steel 304 Industrial Tubular Heater after the completion of production is close to all the power required by the customer.


4. After the production of the Copper Industrial Tubular Heating Element, sometimes the phenomenon of “false resistance” occurs, that is, the resistance value is found to be inconsistent with the setting at the time of production. In case of this phenomenon, our factory will advise the customer to preheat the Copper Industrial Tubular Heating Element, that is, energize the electric heating tube for 3-5 minutes, then cut off the power and then detect the resistance value. The result thus detected will be comparable to the preset resistance value produced.


       With the increasing number of heating pipes and Dryer Tubular Heater Element enterprises, the competition of domestic Dryer Tubular Heater Element enterprises is also constantly upgrading. Nowadays, the scope of Dryer Tubular Heater Element enterprises must include market research, product development or improvement, manufacturing, sales, After-sales service until the whole process of recycling, involving the entire life cycle of the heat pipe products, always pay attention to the concept of serving customers all the way, all-round. Under the same product quality conditions, who can do more in the after-sales service, to a certain extent, determines who can win more market share. At the same time, whether it is to improve quality, increase prices, or adopt trade protection measures, take a diversified route, and increase the value-added road, all aim to enhance their influence and status in the heat pipe market.

         In recent years, the country's investment in industrial industries, electrical appliances, and automobiles has been increasing, and it has gradually driven the development of related heating pipe industries, making the heating pipe enterprises a good applause. At the same time, we must also clearly understand that the guaranteed growth of the entire industry does not mean that all the heating pipe companies can be safe. In order to meet the needs of the industry growth, domestic heating pipe enterprises must actively adjust the product structure and achieve strategic transformation. Starting from the direction of specialization, clustering and grouping, we will explore the creative value of enterprises and gradually develop into brand advantages to achieve different market occupations in different fields of low, medium and high.
