裝修中,常聽工人說4分管、6分管,自己卻不知道是什么意思?其實這指的是管子的外徑,4分管外徑20mm,6分管外徑25mm。選擇哪種管,pvc管業生產,要看水管的外徑來決定。管4分管,只能使用4分管。管是6分管,使用6分管、4分管都可以。另外,水管上也會標注20*2.8、25*4.2,pvc管業品牌,前面的20、25就是指管子外徑,而后面的2.8、4.2則指水管的壁厚。一般管壁越厚,水管就越---。 parameters of ppr tube decoration,潼南pvc管業, often listen to workers say 4 in charge, 6 in charge, but do not know what it means? in fact, this refers to the outer diameter of the pipe. the outer diameter of 4 branch pipes is 20 mm,&that of 6 branch pipes is 25 mm. which kind of pipe to choose depends on the outer diameter of the pipe. only four branches can be used. the management is divided into 6 branches. it is ok to use 6 branches/4 branches. in addition, 20 * 2.8&25 * 4.2 will also be marked on the water pipe. the front 20&25 refer to the outer diameter of the pipe, while the back 2.8&4.2 refer to the wall thickness of the water pipe. generally, the thicker the pipe wall is, the more durable the water pipe is.
ppr管施工后須經試壓驗收后方能封管和使用。ppr管安裝主要采用熱熔管件,熔接時間和壓力不好掌握,工藝隨機性較大,在熱熔推接過程中易產生堆料從而減小通徑,并使熔接處成為不規則的缺陷區,產生應力集中,影響ppr管價格的長期性能;對于ppr管的電熔連接,由于電熔絲主要采用促進ppr降解的銅,會加速ppr管的老化。
ppr pipe can be sealed&used only after pressure test&acceptance.the ppr pipe is mainly installed with hot-melt pipe fittings. the welding time&pressure are not well mastered,pvc管業咨詢,&the process is random. in the process of hot melt push welding, it is easy to generate stacking materials to reduce the diameter,&make the fusion joint become an irregular defect area, which produces stress concentration, which affects the long-term energy of price of ppr pipe; for the electric melting connection of ppr pipe, the aging of ppr pipe will be accelerated because copper is mainly used to promote the degradation of ppr.
