HDPE缠绕结构壁B型管在使用中名称为：高密度聚乙烯（HDPE）缠绕结构壁管B型、HDPE高密度聚乙烯缠绕结构壁增强管(B型)等等，执行国内最新标准为GB/T19472.2-2017。国外统称克拉管，参考的标准就比较多了，其中分为德国标准（DIN），国际标准（ISO）和美国标准（ASTM）等。

In use, the HDPE winding reinforced structural wall B-type pipe is named as: high-density polyethylene (HDPE) winding structural wall pipe, HDPE high-density polyethylene winding structural wall reinforcement pipe (B type), etc., and the implementation of the latest domestic standard is GB/T19472.2-2017. Foreign countries are collectively referred to as cratons, reference standards are more, which are divided into German standards (DIN), international standards (ISO) and American standards (ASTM), etc.

高密度聚乙烯HDPE缠绕增强结构壁B型管以高密度聚乙烯HDPE为主要原料，以相同或不同材料作为辅助支撑结构，经热缠绕工艺成型的埋地排水塑料管材。

The wall pipe of high-density polyethylene winding structure takes high-density polyethylene HDPE as the main raw material, the same or different materials as the auxiliary supporting structure, and the buried drainage plastic pipe is formed by hot winding process.

HDPE缠绕增强管（B型结构壁管）克拉管连接方式为承插电热熔连接，是当前市场上环刚度能达到最高的一种管材，HDPE缠绕增强缠绕管的最小环刚度为SN2，环刚度能达到SN32。

HDPE winding reinforcing tube (B type wall tube) is connected by socket plug hot-melt connection, which is the tube with the highest ring stiffness on the market at present. The minimum ring stiffness of the tube is SN2, and the ring stiffness can reach SN32.

HDPE高密度聚乙烯缠绕结构壁增强管(B型)应用于市政道路排水，化工园区，小区排水，机场建设，海绵城市，地下综合管廊等建设。

HDPE high-density polyethylene winding wall reinforcement pipe (Type B) is applied in municipal road drainage, chemical industry park, community drainage, airport construction, sponge city, underground comprehensive pipe gallery and other construction.

HDPE埋地式聚乙烯缠绕管最小口径为 DN300，最大口径为DN3000。生产技术源自于德国，是当前我国大型城市基础建设中运用比较广的一种管材，其外壁PP材料壁管能够支撑更高的外部压力。

The minimum diameter and maximum diameter of HDPE buried polyethylene winding pipe are DN300 and DN3000 respectively. The production technology is originated from Germany, which is a kind of pipe widely used in large-scale urban infrastructure construction in China at present. The PP wall pipe of its outer wall material can support higher external pressure.

HDPE缠绕增强结构壁B型管（克拉管）随着中国市场的竞争，也出现一些仿克拉管道，如（连续克拉管），其技术是用普通管道生产设备改进而成，外观与缠绕增强结构壁B型管基本相似，但质量和功能远不如真正的克拉管。

With the competition in the Chinese market, there are also some imitated tubes, such as continuous tubes. The technology is improved with the production equipment of ordinary pipes. The appearance of the tubes is basically similar to the B tubes of the winding reinforced structure, but the quality and function are far inferior to the real tubes.
