水路改造需要改變水路方向，一定注意配件的質(zhì)量，配件牌子也要注意，避免工人以次充好，選擇同品牌配件，不同廠家用料配方肯定是不同的，即使熱熔到一起也會留下隱患。配件也分熱水管和冷水管，記得注意。另外，還有水閥、保溫棉、卡扣等配件。

The water road needs to change the direction of water road， pay attention to the quality of accessories， and the brand of accessories. Avoid workers to fill the same brand parts with inferior ones. The material formula of different manufacturers must be different， even if the hot melt together will leave hidden dangers. Accessories also include hot water pipe and cold water pipe. Remember to pay attention. In addition， there are water valve， heat preservation cotton， other accessories.

根據(jù)耐腐蝕性能來參考?

具體來說，PPR管材耐腐蝕與防結(jié)垢性能則施工項目管道的基本需求，優(yōu)良的PPR管材的耐化學腐蝕性能更好，其能夠抵抗水中的化學元素的腐蝕，與此同時，其表面則可避免水垢的形成，以此可以促使輸送的水更加潔凈與衛(wèi)生。

According to the corrosion resistance

Specifically，Corrosion resistance and anti scaling performance of PPR pipe are the basic requirements of building project pipeline. Excellent PPR pipe has better chemical corrosion resistance， which can resist the corrosion of chemical elements in water. At the same time，PVC排水管制造， its surface can avoid the formation of scale， which can promote the transmission of water more clean and sanitary.

給排水管的支吊架，孝感PVC排水管，有的施工人員為了節(jié)省費用，選擇的型鋼偏小，布置的數(shù)量沒達到要求，或者布置的位置不合理。解決辦法：在橫管三通和彎頭附近的地方一般要設(shè)置支吊架（此處一般受水流沖擊力大些）。另外，對于upvc管而言，橫管吊架設(shè)置的間距和它的dn直徑相同，比如dn40的管吊架間距就為40cm。

For the supports and hangers of water supply and drainage pipes，PVC排水管咨詢， some workers choose small parts steel in order to save costs， the number of layout does not meet the requirements， or the location of layout is unreasonable. Solution: the support and hanger should be set near the cross pipe tee and elbow (the impact force of water flow is greater here). In addition， for UPVC pipe，PVC排水管代理， the spacing of horizontal pipe hanger is the same as its DN diameter， for example， the spacing of Dn40 pipe hanger is 40cm.
