As the core component of electric heating equipment, the performance stability of electric heating pipe directly affects all aspects of molding products. For molds, kitchenware, chemical industry, food, medicine and other light or heavy industries that need solid, liquid and gas heating, the performance quality of electric heating pipe cannot be ignored ! 

Annai resistant electric heating, teamwork, professional focus, to ensure the safety of Annai resistant electric heating pipe, durability ! 

In order to ensure the product quality and reputation of themselves and their customers, only better or more suitable materials have been selected. The core components of the electric heating pipe all use high-quality imported seamless stainless steel pipes, high-purity high-temperature resistant insulating magnesium oxide powder, high-quality electric heating wire, and the temperature can reach 1100 °C. 

Through automatic or semi-automatic, pure manual way, in the seamless metal tube ( titanium tube, stainless steel tube, copper tube ) into high-quality electric heating wire, gap part, filled with good thermal conductivity and insulation of magnesium oxide powder, shrink tube, and then processed into the user needs a variety of shapes. 

Production sector 80 % of the technicians have more than ten years of industry production experience. Quality control department is an important department of the company, from raw material testing, machine, electric wire, powder filling, shrinkage, resistance detection, annealing, modeling, drying, water pressure test, voltage test, polishing, welding, fastener installation, finished product testing, packaging and delivery. Each link has a dedicated control, each product is tested according to the process, through the high temperature and high pressure test, internal through, before sending to customers. Try to ensure zero defects

Marking 

Electric heating pipe flange laser marking according to customer requirements, clear writing, clear content. 

Pressure detection 

Measure between the charged parts and the easily touched metal parts, 1800V setting current 5mA, 3mins without flicker and breakdown. 

Input power 

Measured power tolerance + 5 %, -10 % ( or as per customer order ) 

Leakage current 

≤ 0.5mA 

Insulation resistance value 

> 1000MΩ 

Electrification test 

After the electric heating tube is energized, it is dried for 1-2 minutes to ensure that the heating tube heats evenly and there is no abnormal heating phenomenon. 

Resistance value 

The measured values should meet the requirements of drawings 

Creepage distance between the extraction rod and the wall of the heating pipe should be greater than 1mm 

Water pressure test 

Under the pressure of 1.2 Mpa, the welding parts of the heating pipe shall not have leakage, water seepage phenomenon, holding time of 5 minutes 

Packaging should meet transportation requirements.

Set up a professional electric heating tube product laboratory to summarize the past products and practice the new technology
