铝塑管就是由铝和塑料结合而成的，它的内外两层都是塑料，铜梁PVC管业，中间部分是铝，所以说铝塑管同时具备了金属和塑料两种属性。但由于是两种不同的材质，它们的膨胀系数不同，所以铝塑管会出现热胀冷缩的现象，PVC管业厂家，从而导致水管。而PPR管为单一材质，虽然具有低温脆性，但是相比铝塑管，对温度的变化更不敏感，更不易老化破损、更耐用。PPR管的管内很光滑，不容易出现水垢，影响水质的纯净。
做排水管时注意坡度：尤其是空调冷凝排水管，如果管子比较长，施工质量不好容易妨碍排水，导致返水至冷凝水盘漏水。解决办法：按照设计图纸标示的坡度，定好点，放好线，按照相应的间距，下料做好吊支架。
Pay attention to the slope when making the drainage pipe: especially the air conditioning condensate drainage pipe，PVC管业咨询， if the pipe is relatively long and the quality is not good， it is easy to hinder the drainage， resulting in the leakage of return water to the condensate pan. Solution: according to the slope marked on the design drawings， set a good point， set a good line， according to the corresponding spacing， do a good job of lifting support.
ppr管在电气部分：
进地下车库的电缆保护管，套管必须出墙0.5m左右，便于后期电缆封堵及外墙防水。
提前准备后期配套设施的规划图纸，如供配电施工图纸及室外管网图。这样可以缩短交房时间和节约成本。
地下车库的电气预埋前结合风管、管道图纸，避免灯具与风管和管道重叠，造成后期灯具安装时敷设明线，增加造价及影响美观。
PPR tube in the electrical part:
For the cable protection pipe entering the underground garage， the sleeve must be about 0.5m out of the wall， which is convenient for later cable plugging and external wall waterproof.
Prepare the planning drawings of supporting facilities in advance， such as power supply and distribution building drawings and outdoor pipe network drawings. This can shorten the delivery time and save costs.
Before the electrical pre burying of underground garage， the air duct and pipeline drawings shall be combined to avoid the overlapping of lamps with air duct and pipeline， resulting in the laying of open lines during the later installation of lamps， increasing the cost and affecting the appearance.
