For the hotel, hospitals, office buildings, residential and other buildings, for the wire tube material selection, there is no relevant specification is clearly what material? Whether it is PVC pipe or galvanized pipe, or other materials, in the unknown. Detailed, I will give more points more
Ordinary building wiring, there is no clear provisions that use PVC pipe or galvanized pipe, these two materials can be applied.PVC pipe is characterized by light, not rust, cheap, easy construction. Disadvantages is the strength than the galvanized pipe To be bad. And burning smoke, must use the flame-retardant pipe. Galvanized pipe high strength, can not burn, but the construction of PVC pipe is not convenient, the price is relatively high. Also pay attention to the use of metal signal tube, Use shielded signal lines, so as not to form a shielding effect, resulting in signal transmission failure.
Of course, with PVC pipe, because PVC pipe insulation effect of flame retardant, and inexpensive, is generally no substitute for other materials! The The
The problem you are talking about is a matter of fire. Generally for the use of public places in the wire pipe, the fire department is provided, need to achieve a certain fire rating. If you meet the fire rating, use galvanized pipe or use PVC pipe can be. In other words, if you are using a PVC pipe, you need to send this pipe to the fire department. If it is allowed to use, but can not be used - this is the quality of the material problems. In addition, if the building property designated construction unit must use galvanized pipe, also need to use galvanized pipe construction. Of course, the use of galvanized pipe to do wire tube, in the fire more easily through the acceptance. Specific details, direct access to the relevant fire regulations.
