Pressure test glass pipe flushing ① to reduce the increase in temporary pipeline purge, purge pressure test to save time and improve the passing rate of the purge pressure test, pipeline pressure testing, purging work as systems, patches, pressure levels were, pressure test must be prepared to guide the construction plan before the purge. ② pipeline pressure test using clean water, when attached to a stainless steel piping when testing and flushing, chloride ion content in water should not exceed 25 × 10 (25ppm), pipeline pressure testing and flushing procedures to implement the provisions of the general contractor. ③ When the pressure test, unrelated persons allowed to enter. Pressure test is completed, the pipeline can not be repaired. (L) the heating pipes at both ends usually have a longer cold side glass and steel pipe, and can not play the role of heating. Power Design (2) heating section to try not to exceed the limit of 10 watts / cm. As 30 cm long heating pipe, try not to exceed 300 watts of power. If the design power exceeds this limit, the higher the heating tube surface load, easily oxidized steel corrosion, causing a short circuit. (3) to a temperature higher than 250 ℃ mold design, the use of heat pipe has some difficulties. I have a heating pipe temperature reaches 420 ℃, but the higher the temperature of the heating pipes forming such quality requirements, and the need to frequently check the patency of a short circuit or not. Under these conditions because the heating pipes, terminals, connected with copper, steel and other media are very susceptible to oxidation, resulting in disconnection. Therefore, the electrical transmission medium require special handling, try to avoid conducting wires exposed to the air, to extend the life of the wire. Iron core is also commonly used as a glass pipe fitting mold heating pipe, is characterized by high power per unit length (typically 10mm diameter glass pipe pillow, 8cm long iron core sizes up to 150 watts of output power), durability, safety, difficult to form a short-circuit breakdown can be buried by drilling blind holes, the disadvantage is difficult to customize the design, replace them brittle, broken. Circuit Design indispensable insurance, air switch insurance policy maintained by the operation to be clean and tidy, good insulation, diligent in checking the operation of electrical failure, to prevent unnecessary danger.
