The difference between single-wall bellows and double-wall bellows
Plastic double-wall corrugated pipes can be widely used in highways, slopes, golf courses, etc. under heavy copy load drainage and permeation; municipal sewage; communications, power supply cable bushings and other occasions.
Single-wall corrugated pipes can be widely used for drainage and permeation under light loads such as golf courses, sports fields, etc .; interior decoration electric hundred-line bushings; automotive wire bushings; prestressed anchor cable bushings; air conditioner drain pipes.
Under the same strength and rigidity requirements, the use of double-wall corrugated pipes can save 30% -50% of materials than ordinary plastic pipes, which has better technical and economical efficiency, and is easy to transport and install, reducing the labor intensity of construction personnel. The total investment of the project is reduced, but the degree of winding is small.
3. Weight and ring stiffness
HDPE double-wall corrugated pipe is much heavier and heavier than single-wall corrugated pipe, and double-wall corrugated pipe has much higher rigidity than single-walled ring.
