Nestable Corrugated Steel Pipe: Flange-Type and Notch-Type for Easy Assembly

Nestable Corrugated Steel Pipe is an innovative piping solution designed for efficient handling, transportation, and installation. Unlike traditional corrugated pipes, these pipes feature a unique nestable structure, allowing them to be bundled and nested together for space-saving storage and easier transport. This feature is particularly beneficial for remote projects or sites with challenging construction conditions.

Nestable Corrugated Steel Pipe (CSP) is a versatile and efficient piping solution designed for a variety of construction and infrastructure applications. Available in two types—flange-type and notch-type—this pipe system offers ease of transportation, assembly, and installation.

Types of Nestable Corrugated Steel Pipes

Flange-Type Nestable Corrugated Pipe: This design features protruding flange plates with pre-drilled holes, allowing two semi-circular sections to be securely bolted together using galvanized 10mm bolts and nuts. The flange-type is ideal for installations where easy assembly and secure connections are required.

Riveting-Type Nestable Corrugated Pipe: In this design, the semi-circular sections do not have flanges. Instead, they have pre-drilled holes at both ends for simple and quick assembly using rivets. This option is more cost-effective, especially in terms of labor savings during installation.

Both types are made of galvanized steel, ensuring long-lasting durability and resistance to corrosion under normal environmental conditions. Their nestable design makes them an ideal choice for large-scale projects, including those in remote locations or areas with difficult access, as they offer significant savings in transportation and handling costs.
