PVC缠绕管排水管道规范是啥?规格型号有什么?

作者: laobingguandao    来源:http://www.laobingguandao.com  时间:2020-09-25    人气:
常见的PVC缠绕管排水管规格关键是依据公称压力直径各自为31mm,50mm,60mm,70mm,95mm,120mm,250mm,165mm,150mm,350mm,3.15mm,350mm,600mm,大部分PVC盘绕排水管规格常有必须的差别, 这一是一切正常的。 PVC盘绕排水管道的长短一般为4米或6米,别的长短由经销商和买家商议明确。
The key to the specification of common PVC wound drain pipe is that the nominal pressure diameter is 31mm, 50mm, 60mm, 70mm, 95mm, 120mm, 250mm, 165mm, 150mm, 350mm, 3.15mm, 350mm, 350mm. Most of the specifications of PVC coiled drain pipe often have necessary differences, which is normal. The length of PVC coiled drainage pipe is generally 4 m or 6 m, and the other length shall be determined by the dealer and the buyer.
1.锯管和带槽。锯PVC盘绕排水管道的长短依据实际上精确测量自上而下明确,并与每一软管的规格紧密结合。锯管专用工具一般应应用细齿锯,切割和切管器。缝隙应平整,横截面不需有形变。待粘合的一部分折叠式成带中厚板的16o~40o槽,槽的长短通常不低于3mm,槽的薄厚应是薄厚的1 / 3~1 / 2。壁厚。除去残片。
1. SAW pipe and groove. The length of the sawn PVC coiled drainage pipe is determined from the top to the bottom according to the actual accurate measurement, and closely combined with the specification of each hose. In general, the special tools for pipe sawing shall be fine toothed saw, cutter and pipe cutter. The gap should be flat and the cross section should not be deformed. The length of the 16O ~ 40o groove of a part of folded band medium plate to be bonded is usually no less than 3mm, and the thickness of the groove should be 1 / 3 ~ 1 / 2 of the thin thickness. Wall thickness. Remove the debris.
2,维护PVC缠绕管排水管道socket插口。一般,在联接电源插座插口后,应应用纯棉纱或湿布小量甲苯擦洗挤压的黏合剂。在于黏合剂的特性和气侯标准,直至页面干固。假如在冬天应用,尽可能增加干固時间。
2. Maintain socket socket socket of PVC wound drain pipe. In general, after connecting the power socket socket, the pure cotton yarn or wet cloth should be used to scrub and squeeze the adhesive with a small amount of toluene. It depends on the characteristics of the adhesive and the weather standard until the page is dry and solid. If it is used in winter, the drying time should be increased as much as possible.
pvc盘绕排水管道的经济收益和社会经济效益
Economic and social economic benefits of PVC coiled drainage pipeline
一要大大缩短工程施工周期时间,减少工程施工难度系数:pvc盘绕排水管道品质比水泥排水管轻,有利于带上,工程施工难度系数大幅度降低; HDPE双壁钢塑复合管短至6米。
First, it is necessary to greatly shorten the construction cycle time and reduce the difficulty coefficient of Engineering Construction: the quality of PVC coiled drainage pipe is lighter than that of cement drainage pipe, which is conducive to carrying on, and the engineering construction difficulty coefficient is greatly reduced; HDPE Double wall steel plastic composite pipe is as short as 6m.
一,水泥排水管长2.3米,大大缩短了工程施工周期时间。
1、 The cement drainage pipe is 2.3m long, which greatly shortens the construction period.
二,HDPE两层平壁钢塑复合管底沟不高:因为水泥排水管是无缝钢管,为了确保电源插座的实际效果,沟的底端务必整平,更好是打下基础层,施工队伍要有絕對的义务。 pvc盘绕排水管道是这种柔性管,管沟底端不用。
2、 The bottom ditch of HDPE two-layer flat wall steel plastic composite pipe is not high: because the cement drainage pipe is seamless steel pipe, in order to ensure the actual effect of the power socket, the bottom end of the trench must be leveled, and it is better to lay the foundation layer. The construction team should have absolute obligations. PVC coiled drainage pipe is this kind of flexible pipe, which is not used at the bottom of the trench.
三,pvc缠绕管排水管道不容易毁坏地面塌陷或地壳转变; pvc盘绕排水管道的延伸率是无缝钢管的30倍左右,是PVC的6.3倍,拉伸强度十分高,延伸率很高。这代表pvc盘绕排水管道能够在土层地面沉降或地壳转变时造成摩擦阻力形变而不容易裂开。这远远地好于无缝钢管,也好于具备显著延性的PVC管。这类特性已在世界各国获得确认(日本国阪神地震沒有造成管路裂开;聚乙烯塑料管路在Zhinan的合肥庐阳区地震灾害中沒有被毁坏)。
3、 It is not easy to destroy the ground collapse or crustal transformation of PVC wound drainage pipe; the elongation of PVC coiled drainage pipe is about 30 times of that of seamless steel pipe and 6.3 times of that of PVC, and the tensile strength and elongation are very high. This means that the PVC coiled drainage pipe can cause friction resistance deformation and not easy to crack when the soil surface subsidence or the earth's crust changes. This is much better than seamless steel pipe and PVC pipe with remarkable ductility. This kind of characteristic has been confirmed all over the world (the pipeline was not cracked due to the Osaka Kobe earthquake in Japan; the polyethylene plastic pipeline was not damaged in the earthquake disaster in Luyang District, Hefei, Zhejiang Province).
四,pvc盘绕排水管道的亲水性远远低于水泥排水管,小于2%,不容易对地表水导致污染;水泥排水管是无弹性的,尽管它装有硅胶圈,但密封性实际效果差,非常由于施工队伍因水泥排水管净重大而太重,硅胶圈的工程施工不太好,并且罩衣丧失其功效,进而提升管路的亲水性。
4、 The hydrophilicity of PVC coiled drainage pipe is much lower than that of cement drainage pipe, which is less than 2%; The cement drainage pipe is inelastic. Although it is equipped with silicone rubber ring, the actual sealing effect is poor. Because the construction team is too heavy due to the net weight of the cement drainage pipe, the engineering construction of the silicone rubber ring is not good, and the cover loses its efficacy, thus improving the hydrophilicity of the pipeline.
