双壁波纹管和单臂波纹管有什么不一样 What is the difference between double wall bellows and single arm bellows

双壁波纹管介绍

1、高密度聚乙烯(HDPE)双壁波纹管,是一种具有环状结构外壁和平滑内壁的新型管材,80年代初在德国首先研制成功

2、经过十多年的发展和完善,已经由单一的品种发展到完整的产品系列.目前在生产工艺和使用技术上已经十分成熟

3、由于其优异的性能和相对经济的造价,在欧美等发达国家已经得到了极大的推广和应用

4、在我国,HDPE双壁波纹管的推广和应用正处在上升势态阶段,各项技术指标均达到使用标准

5、双壁波纹管内壁颜色通常有蓝色和黑色,部分品牌内壁会使用黄色

Introduction of double wall bellows

1. High-density polyethylene (HDPE) double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. It was first developed in Germany in the early 1980s.

2. After more than ten years of development and improvement, it has developed from a single variety to a complete product series. At present, it is very mature in production technology and use technology

3. Due to its excellent performance and relative economic cost, it has been greatly promoted and applied in developed countries such as Europe and the United States.

4. In China, the promotion and application of HDPE double-wall corrugated pipes are in an upward trend, and all technical indicators have reached the standards for use.

5. The inner wall of double-wall corrugated pipes is usually blue and black, and some brands use yellow.

 

双壁波纹管的优点

1、结构合理外型美观,卫生性能可靠,节能降耗

2、耐温性能-40℃-60℃,强度高,抗震性能强,耐酸碱抗腐蚀

3、阻力小,流量大,阻燃力强·使用寿命长

4、综合造价低,安装运输方便

Advantages of double wall bellows

1. Reasonable structure, beautiful appearance, reliable sanitary performance, energy saving and consumption reduction

2. Temperature resistance -40 ℃ -60 ℃, high strength, strong shock resistance, acid and alkali resistance and corrosion resistance

3. Small resistance, large flow, strong flame resistance, long service life

4. Low comprehensive cost, convenient installation and transportation

 

PVC单壁波纹管简介

PVC单壁波纹管是以PVC为主要原料,经挤出吹塑而成,PVC单壁波纹管利用其环形槽的结构,可兼备硬pvc管的刚性和软管的柔性,因此使管子具有刚中带柔的特点,可用于输送某些液体和气体以及作为预埋电线的套管。

Brief introduction of PVC single wall corrugated pipe

PVC single-wall corrugated pipe is made of PVC as the main raw material and is extruded and blow-molded. PVC single-wall corrugated pipe uses its ring groove structure to have the rigidity of rigid pvc pipe and the flexibility of the hose, so the pipe has a rigid The medium-flexible feature can be used to transport certain liquids and gases and as a casing for embedded electric wires.

 

单壁波纹管与双壁波纹管的区别

1、单壁波纹管:内、外表面均为波纹状

2、双壁波纹管:内壁平滑,外壁为波纹状

The difference between single wall bellows and double wall bellows

1. Single-wall corrugated pipe: the inner and outer surfaces are corrugated

2. Double-wall corrugated pipe: the inner wall is smooth and the outer wall is corrugated
