Overburden depth higher plea. Under ordinary roadway SN5000 grade glass pipe most shallow covering not less than 0.8m; the deepest casing is not greater than 3.0m; SN2500 grade glass pipe most shallow covering not less than 0.8m; the deepest casing not more than 1.2m (12mm thick steel plate and pipe a minimum The deepest 0.7m respectively overburden and 4.0m). FRP pipe has been installed in the open three, construction repair cracks in pipes, pleading similar conditions inside the plant completely dry and the construction when the use of resin and fiber cloth need 7-8 hours of curing, and on-site construction and general Buxiu difficult to achieve this plea. Backfill shall not be rich than 50mm of brick, stone and other hard objects to avoid damage pipe wall. There are currently no large-scale water department to see about the country's large-scale use reported glass pipe, and the pipe because the glass pipe is new, therefore, glass pipe market space is broad. (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 tube glass pipe, try not to exceed 300 watts of power. If the design power exceeds this limit glass pipe, heating tube surface load high glass pipe manufacturers, steel pipes corrode 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, resulting in disconnection. Therefore, the electrical transmission medium require special handling to avoid making conduction wire exposed to the air, to extend the service 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, glass pipes, difficult to form strike wear short 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.
