Industrial and commercial use resistive heating system Part 2. system design, installation and maintenance Application Guide1 ScopeGB/T 32348 in this part of the resistive heating system design in industrial and commercial applications, installation, maintenance and repair made Detailed recommendations. This section does not include potentially explosive atmospheres in any application. This section applies to electric heating system relates to the factory or assembly site (construction site) mounting assembly, and has been in accordance with the manufacturer's Series and parallel with the surface of the heater or heater assembly out and/or terminated (with heating pads and hot plate). Some of the products covered by the appropriate technical training personnel trained to install, and can only be performed by trained personnel especially critical Work, such as joints and the end of the installation. Installation required under the supervision of a qualified electrician perform the electrician should have received electric heating system complements Charge training. This section does not include induction, impedance or skin effect heating. Electric heating system can be divided into different types of applications under different conditions after installation and installation need to meet different test requirements. Electric heating systems are generally applicable to a specific type of device or application. Typical applications of different types of installation include, but are not limited to. a) piping, vessels and associated equipment for heating surface heating device applications include. --- Freeze protection and temperature; --- Hot water pipes; --- Petroleum and chemical pipeline; --- Sprinkler systems. b) outdoor open space heating devices, applications include. --- Roof de-icing; --- Drains and sewers de-icing; --- Sump and drain; --- Track heated. c) heating systems with embedded devices, applications include. --- Snow; --- Warm; --- Prevent ice expansion; --- Underground thermal energy storage system; --- Doorframe. d) conduit or pipe with an internal heating system installation, applications include. --- Snowmelt (in conduit); --- Frost protection (in conduit); --- Warm (in conduit); --- Energy storage system (in conduit); --- Internal piping drinking water heating; --- Closed drains and sewers. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 32348.2-2015_English be delivered?Answer: Upon your order, we will start to translate GB/T 32348.2-2015_English as soon as possible, and keep you informed of the progress.
