HDPE钢带增强聚乙烯螺旋波纹管的结构应用及与其他排水管道的性价对比Word格式文档下载.docx

1、中空壁缠绕管纯HDPE材质，在2个冷的（或者有一些温度的）矩形管之间挤出熔接料，靠缠绕时的轴向推力和焊接料的热量融化冷矩管的两侧而完成焊接过程，严格的讲，这种焊接是非等温熔接的，熔接料的热量很关键，溶解量太少或温度太低，都会因热容量不足而产生假熔接现象，在加上熔接缝太长，熔接质量很难控制，熔接处易出现开裂、漏水现象、可靠性能差。没有埋地示踪性。HDPE双壁波纹管纯HDPE材质，由机头磨具同时挤出内。外连续管坯，在熔融状态下，通过内、外气作用及水的冷却成型为内壁光滑、外壁具有同心圆环形加强肋的管材。玻璃钢管除纯玻璃钢管外，作于排水管的主要是玻璃钢夹砂管，他是一种热固性塑料制品。以玻璃纤维为增强材

2、料，以不饱和聚脂树脂为基体材料、以石英沙维填充材料二制成。管壁由内衬层。结构层、夹砂层和表面层组成，为实壁管。水泥管道材质为水泥（或内有钢筋增强）、内带钢筋的水泥管具有埋地示踪性2耐腐蚀、老化性能及使用寿命耐腐蚀性、老化性能及使用寿命HDPE螺旋缠绕波纹管由于管道材料为耐腐蚀的HDPE，因此不会被污水及废水中的酸碱及油份等腐蚀，耐腐蚀性强；同时本身惰性的HDPE管道材料中，加入了抗氧剂、光稳定剂等抗老化助剂，抗老化性能优异；加之管道的基材特性在20可有效使用50年以上，故管道使用寿命可达50年。由于管道于外界接触的材料为耐腐蚀的HDPE，因此不会被污水及废水中的酸碱及油份等腐蚀，耐腐蚀性强；加

3、之管道的基材特性在20可有效使用50年以上，故管道使用寿命可达50年由于管道于外界接触的材料为耐腐蚀的HDPE，因此不会被污水及废水中的酸碱及油份等腐蚀，耐腐蚀性强:热固性塑料构成的管材抗老化性能较好。可使用寿命50年水泥管水泥在遇到雨水（酸性）、下水。工业废水、温泉水时，容易发生劣化。特别是酸性物质（药品）等,对水泥的腐蚀破坏力很大。故作为排水管的水泥管可使用寿命一般不超过20年。3抗外力作用及耐地基不均匀沉降能力抗外力作用及耐地基部均匀沉降能力由于管道为柔性管道，受到外部冲击力时，恢复原形优越。耐地基不均匀个沉降能力强。为钢塑复合管道，管道刚柔并济，受到外部冲击力时，恢复原形优越。为柔性管

4、道，受到外部冲击力时，恢复原形一般，主要因为方管间的粘接强度低，当外力过大时，粘接处易开裂，耐地基不均匀沉降能力一般为柔性管道，受到外部冲击力时，恢复原形性能一般，主要因为，其波峰宽厚度小，受外力冲击时，波峰易塌陷。耐地基不均匀沉降能力强由于管道为刚性管道，受到稍大外部冲击力时，管道易脆。耐地基不均匀沉降能力差由于管道为刚性管道，受到大的外部冲击力时，管道易脆。4.环刚度环钢度利用小口径实壁方管作为螺旋缠绕波纹的加强结构，使管材环刚度可达到SN4KN/m，SN8KN/m钢骨架做增强体的中空环形结构，环刚度SN10KN/m，可更具工程需要生产出环刚度为SN8KN/m，SN12.5KN/m，SN1

5、6KN/m的管材方管或矩形管道通过缠绕熔接的结构壁管设计，在大口径管材上（管径800），环刚度达不到8KN/m，一般该种管材的环刚度等级仅为2KN/m，4KN/m同心圆环形结构增强设计，在大口径管材上（管径800）刚性管材5.耐磨损性能.耐磨损性能这4种管材与输送介质接触的材料均为耐磨损性能极佳的高密度聚乙烯，采用10%金刚砂（果120目沙砾/水）泥浆，以14n/s喷射速度，70倾斜角做水喷试验，其质量损失为20mg体积损失为21mm，而钢的质量损失为1081mm，造就了PSP管优异的耐磨性能，是钢管的6倍耐磨损性能一般耐磨损性能差6管材重量（运输及安装时的搬运）管材重量管材重量仅为同规格混泥

6、土的1/8，便于运输，施工方便不需使用大型施工设备。管材重量仅为同规格混泥土的10%，传统缠绕塑料结构管的70%，便于运输，不需使用大型施工设备为传统缠绕塑料结构管，管材质量为同规格混泥土管的14%小于&1000口径时与钢骨架螺旋缠绕波纹管质量相近（同环刚度），当口径&1000时，重量将比钢骨架螺旋缠绕管大。且因生产工艺、设备等原因，目前生产的最大口径为%1000约为水泥管的20%重量大，运输费用高，施工需要使用大型的施工设备作为管材，尤其是大口径管材的声场基地辐射半径为500公里。对于有一定规模的工程，HDPE螺旋缠绕波纹管、钢骨架螺旋缠绕波纹管、中空壁缠绕管可将生产设备拖到施工现场生产管材

7、。而双壁波纹管、玻璃钢管、水泥管由于生产设备及加工工艺无法做到这一点。7.连接方式及可靠性连接方式及可靠性我公司主要采用热收缩带连接、焊接连接，必要时可以结合应用两种连接方式，连接简便迅速（尤其是焊接连接方式，只需廉价的PE焊条，费用低，速度快），密封性能好，管道无渗漏，抗不均匀沉降能力强。且不会像轴承插接连接方式那样会减少管材的有效长度主要采用热收缩管（带）连接，焊接接连、哈夫套连接等方式。但因其结构原因，醉经济的焊接连接方式必须进行管材内外壁双面焊接，增加了施工难度和速度，其他同上主要采用橡胶承插连接方式。连接简便迅速，但密封性能一般，有少于渗漏。加之在线扩口技术存在缺陷，影响使用寿命。且

8、承插连接方式那样会减少管材的有效长度连接简便迅速，但密封性能一般，有少许渗漏。且承插连接方式那样会减少管材的有效长度。A国内平接口水泥管在连接处仅抹一圈混泥土密封，在施工种难于保证不泄露，密封性能差加之混泥土管为刚性管，稍有移动（土壤不均匀沉降）就可造成连接处破坏。B橡胶圈密封承插连接，由于水泥管自重会使橡胶圈的弹力法师变化，造成下面紧配合，管材上面的密封性能差，从而产生渗漏。且承插连接方式会减少管材的有效长度C水泥麻袋承插连接，自重大的刚性水泥管稍有异动9如果土壤不均匀沉降）就可造成连接处破坏。综合:由于水泥管重量重，不易生产长管道，一般为12米、根，接头多，接头密封及可靠性差，渗漏量相当大

9、，当地下水位低于管道时，渗漏将影响管道的排水量，且污水造成土壤的再次污染，当地下水位高于管顶时，将导致水土流失，管道下沉，路面塌陷，同时加大了污水处理的费用。8环保性环保性在使用过程中不结构，不生锈，不滋生藻类和替他的微生物，不需要阴极保护及其他防护措施，不会对水质或其他介质产生二次污染，管材抗渗透性强，管道接头可靠且密封性好，不渗漏，加之聚乙烯本身是无毒性可再生利用材料，不会污染环境，故环保性能好。管道接头可靠性、密封性较稍差，有少许渗漏，会造成土壤的再次污染。管道接头可靠性、密封性稍差，有少许渗漏，会造成土壤的再次污染。同时由于管道材质主要是为热固性塑料，不可再生利用在使用过程中会结垢，滋

10、生藻类和其他薇生物，需要防护措施，头则会对水质或其他介质产生二次污染，管材抗渗透性差，管道接头多，接头不可靠切密封性差，造成泄露量大，造成土壤的再次污染，水泥管为不可再生利用材料，故环保性能差（英文版 ） Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementation of comprehensive strictly strategic plan, implementation i

But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too complicated, eight prohibition,
