Integral Galvanized Corrugated Steel Pipes

Integral corrugated metal pipe, as its name implies, is characterized by its monoblock annular structure made of quality corrugate metal sheet and welded in a roll welding. It has high strength, durability, versatility as well as a strong structure that ensures long life. Most of all, it is easier and quicker to be installed on site compared with assembled corrugated metal pipes. Thus, integral corrugated metal pipes are ideal for projects in severe construction conditions, such as severe sedimentation areas. However, integral corrugated metal pipe are not convenient to transport, so it is recommended to be applied to projects in a short transportation distance.

As a professional manufacturer, we offer two types of integral corrugated metal pipes as shown in the following two pictures.

Twelve integral corrugated metal pipes with welded flange plates for easy installation.

Inserted type integral corrugated metal pipes without flange plates.

Welded flanges with punched holes are designed for easy connecting integral corrugated metal pipes together. However, our patented inserted type pipes feature punched holes at both ends of pipes for easier installation, higher leak tightness as well as higher anti-press strength. In addition, inserted type pipes have no flange plates let alone open welding of flange plates.
