玻璃纤维增强塑料,又称玻璃纤维增强塑料,其中双扣聚乙烯增强管是由玻璃纤维、不饱和聚酯树脂和石英砂填料组成的一种新型复合管材。该产品主要由计算机控制的往复交叉绕组和离心铸造而成,具有一系列优良的特性。它是美国、欧洲等发达国家广泛使用的工业管道之一,并制定了完整的管道产品标准和工程设计安装规范。
Glass fiber reinforced plastics, also known as glass fiber reinforced plastics, double button polyethylene reinforced pipe is a new type of composite pipe composed of glass fiber, unsaturated polyester resin and quartz sand filler. The product is mainly made of computer controlled reciprocating cross winding and centrifugal casting, with a series of excellent characteristics. It is one of the industrial pipelines widely used in the United States, Europe and other developed countries, and has formulated complete pipeline product standards and engineering design and installation specifications.
管壁结构由内向外:内衬层、内缠绕层、树脂砂浆层、外缠绕层、外保护层。衬里层的角色防腐、防渗,绕组层和树脂砂浆层扮演管道的强度和刚度,和外防护层起到抗衰老的作用,防腐和anti-sun,复合材料的可设计性的体现。
The pipe wall structure is from inside to outside: inner lining layer, inner winding layer, resin mortar layer, outer winding layer and outer protective layer. The role of lining layer is anti-corrosion and anti-seepage, winding layer and resin mortar layer play the role of pipeline strength and stiffness, and the outer protective layer plays the role of anti-aging, anti-corrosion and anti sun, the embodiment of designability of composite materials.

1. 运输安装方便
1. Convenient transportation and installation
A.双扣聚乙烯加强管单位长度重量约为钢管的1/4,装卸、运输、安装十分方便,无大型起重设备,各种支管安装方便,无任何限制。用户可以通过培训轻松掌握玻璃钢管的安装技术。
A. The weight per unit length of the double buckle polyethylene reinforced pipe is about 1 / 4 of that of the steel pipe. It is very convenient for loading, unloading, transportation and installation. There is no large lifting equipment. The installation of various branch pipes is convenient without any restrictions. Users can easily master the installation technology of FRP pipes through training.

b、每根PVC双扣缠绕管长度为12米,与钢管相比,减少了接头数量。长距离管道的安装可提高安装速度,减少泄漏的可能性。
b. The length of each PVC double buckle winding pipe is 12 meters, which reduces the number of joints compared with steel pipe. The installation of long distance pipeline can improve the installation speed and reduce the possibility of leakage.
2、压力测试灵活,维护方便,成本低。
2. Flexible pressure test, convenient maintenance and low cost.
A.由于采用双“0”型密封圈,实现了双通道密封,既能承受管道内较高的外压,又能承受管道内较高的内压。密封可靠,安装后可在两个止水胶圈之间进行压力试验,以缩短施工周期。
A. Due to the use of double "0" type sealing ring, the double channel sealing is realized, which can not only bear the higher external pressure in the pipeline, but also bear the higher internal pressure in the pipeline. After installation, the pressure test can be carried out between the two sealing rubber rings to shorten the construction period.
B,由于双PVC盘管腐蚀,无渗漏,不会产生二次污染地下水和土壤,不需要做内部和外部表面防腐处理,因此,在工程不需要防锈,防腐、防污、绝缘等措施和维护,长期运行维护成本低,阴极保护的埋管不需要做,可以认为玻璃钢管道基本的维护成本。
B. Due to the double PVC coil corrosion, no leakage, no secondary pollution of groundwater and soil, no need to do internal and external surface anti-corrosion treatment, therefore, in the project, there is no need for anti rust, anti-corrosion, anti fouling, insulation and other measures and maintenance, long-term operation and maintenance cost is low, the buried pipe of cathodic protection does not need to be done, which can be considered as the basic maintenance cost of FRP pipeline.
