EMT pipe bender manufacturer tells us that the building drainage pipe should use building drainage plastic pipe and fittings or flexible joint mechanism drainage cast iron pipe and corresponding fittings. Metal drainage pipes shall be used in places where the ambient temperature may be below 0 ℃; drainage pipes with continuous or frequent drainage temperature greater than 40 ℃ or instantaneous drainage temperature greater than 80 ℃.
For pressure drainage pipe, EMT pipe bender manufacturer tells you that pressure resistant plastic pipe, metal pipe or plastic coated composite steel pipe can be used. When the water flow noise of ordinary plastic drainage pipe can not meet the noise control requirements for buildings with higher building standards and places with quiet environment, corresponding air sound insulation or structural sound insulation measures should be taken, such as the selection of special anechoic pipes and pipe fittings, the use of wall pipe supports with good sound insulation effect, and the wrapping of anechoic insulating materials on the outer wall of pipes passing through the floor Materials, equipment, ventilation pipe, etc.
EMT pipe bender manufacturers tell users that when choosing plastic drainage pipes for experimental buildings, teaching buildings or hospitals that discharge acid and alkaline wastewater, they should pay attention to the erosion of the acid-base and chemical composition of the wastewater on the plastic pipe material and interface material. In high-rise buildings with building height more than 100m, the drainage pipe shall be made of cast iron pipe with flexible joint mechanism and its fittings. Plastic pipe and cast iron drainage pipe with flexible joint mechanism can be used for ventilation pipe.
