Widest choices of Corrugated metal pipes

Corrugated metal pipe gets its name for its corrugated patterns around the external surface of steel pipes. As the professional designer and manufacturer of quality corrugated metal pipes, our company can provide the widest choices for our customers.

Three main patterns including annular, spiral and spiral rib patterns are available for our corrugated metal pipes.

A choice of patterns

According to its external patterns, corrugated metal pipes can be classified into three types: annular corrugated pipes, spiral corrugated pipes and spiral rib pipes. These patterns are considered important influence factors of hydraulic efficiency. For example, annular corrugated metal pipes feature parallel corrugations which may affect the flow of water even result in silt deposition if water carries sands and dirt. Spiral corrugated metal pipes are characterized by their spiral patterns for enhancing hydraulic efficiency. However, spiral rib pipes have smooth inner surface which allows liquid flow to pass through without any boundary turbulence. In addition, different patterns also affect assembly methods.

A choice of assembly methods

Corrugated metal pipes are available in three main styles - integral, assembled and lock-seamed styles as shown below:

Three main types of corrugated metal pipes including integral corrugated metal pipe, assembled corrugated metal pipe and lock-seamed types such as spiral corrugated pipes and spiral rib pipes.
  • Integral corrugated metal pipes allow for the easiest installation as each pipe is pre-fabricated prior to shipment, which eliminates pipe assembly on site.
  • Assembled corrugated metal pipe refers to a pipe constructed by bolting various corrugated plates together. They are ideal for projects requiring large diameter that exceeds the maximum diameter of integral corrugated metal pipes. Meanwhile, nestable corrugated pipes can also provide an easy assembly method and allow for easy transportation.
  • Lock-seamed patterns are normally applied to spiral pipes including spiral corrugated metal pipes and spiral rib pipes. Lock-seamed structures provide an easy assembly method just hooking up plate edges together. Meanwhile, they are easy to handle and transport.

A choice of coatings

Different types of coatings are available to enable corrugate pipes to prevent against rust and corrosion. We offer three main types of coatings - zinc coating, polymer coating and asphalt coating as shown below.

  • Zinc coating - Zinc, plated on the interior and exterior of corrugate metal pipes, can sacrifice itself to protect core material form corrosion. So they efficiently prolong the service life of corrugated metal pipes. Our products are galvanized with heavy coating more than 84um in thickness, so they can last no less than 50 years if used in an appropriate way.
  • Polymer coating - Polymer, as a tough material with great resistance against corrosive materials, is generally painted to galvanized corrugated pipes. Meanwhile, they bond well with zinc coating to form integral part without delamination. Polymer coating extends the lifespan of our corrugated pipes to the largest extent.
  • Asphalt coating - Asphalt is a common material coated on the internal and external surface of corrugated metal pipes for providing excellent protection to soil side and water side.

Corrugated metal pipes can be manufactured in different diameters and lengths upon the request of your projects. Various corrugation styles are available including 68mm × 13mm, 75mm × 25mm, 125mm × 25mm, 45mm × 60mm, 150mm × 50mm, 200mm × 55mm, 300mm × 110mm, 380mm × 140mm, 400mm × 150mm, etc. Meanwhile, a wide range of accessories can be offers including end sections, joints and fittings.

What are corrugated metal pipes used to?

Corrugated metal pipe can also be in various projects as shown below:

Corrugated metal pipes are generally used in various projects such as highway culverts, pipeline protection, arched passage and archway in a bridge.
  • Drain system.
  • Underground cable protection.
  • Underpasses.
  • Culverts.
  • Storm water detention.
  • Tunnels.
  • Coalmine vent pipes.
  • Bridges.
  • Drain pipes.
  • Agricultural irrigation.
  • Storm sewer projects.
  • Passages for wildlife and vehicles, etc.
