(L) heating the tube ends generally have a longer cold side, and can not play the role of heat. Power Design (2) heating section to try not to exceed the limit of 10 Watts / cm. Such as the 30 cm long heated pipe, try not to exceed 300 watts power. If the design power exceeds this limit, the heating tube surface load high fire glass pipes, pipe corrosion easily oxidized, causing a short circuit. (3) For temperatures higher than 250 ℃ mold design, using heat pipes have a certain degree of difficulty. I have availed heating temperature reached 420 ℃, but this molding temperature higher quality requirements for heating, requiring constant checking patency and a short circuit or not. Since this condition heating pipes, terminals, connecting copper, steel and other media are very susceptible to oxidation quality glass pipe, causing disconnection. Therefore, the electrical transmission medium require special handling to avoid making conduction wire exposed to the air of acid glass pipe, extend the life of the wire. Iron core is also commonly used as a mold heating pipe, is characterized by high power per unit length (usually a diameter of 10mm, length 8cm specifications iron core can achieve 150 watts of output power), durability, safety, and easy to form short-circuit breakdown can be buried by drilling blind holes, the disadvantage is difficult to customize the design, replace them fragile, broken. Circuit Design indispensable insurance, air switch insurance policy held by the operation to clean, good insulation, operation diligent checking electrical failure, to prevent unnecessary danger. FRP pipe also known as the power of glass fiber reinforced plastic pipe, it is the power cable, underground facility under CNOOC through cables or by the outside world at the time of collision can play a very good protection devices. FRP pipe superior power, what does? Take a look at it! Advantages of a fiberglass tube bending elasticity of power is a good, completely solve the shortcomings of the metal pipe perishable or no flexibility, but also easy to aging or to overcome the poor impact strength deficiencies. Superiority Second, fiberglass power tube has a non-magnetic glass pipe, so to make up a steel pipe eddy current generated by the cable heat, damage defect phenomenon. Three advantages, FRP pipe handling when electricity than metal pipe and cement to be easy and convenient installation and construction is also very convenient.
