Sn4 hdpe corrugated tube

Types of SN4 HDPE Corrugated Tube

The SN4 HDPE corrugated tube comes in some variants, depending on the needs and requirements of consumers. Such variants include:

• Single-wall corrugated pipes

  The single-wall corrugated pipes are thus simple and ergonomic structures where a single layer of HDPE forms a pipe with a corrugated and smooth interior and exterior. Even though such tubes are lesser in thickness in comparison to dual-wall tubes, they are favorable for tough waters or environments. These compact tubes are often used for draining purposes including agriculture or as a construction underpinning drain. In the recent past, such pipes have become popular in sewage and wastewater management due to their flexibility and resistance to clogging.

• Double-wall corrugated pipes

  The synthetic polymer concrete pipes have two distinct layers that come with an inner smooth wall and a outer corrugated wall. This helps combine their toughness, flexibility, and resistance to high pressures or adverse environments. The inner smooth wall facilitates easy carrying or flow, while the outer corrugated wall increases sturdiness and helps in rooting. Such pipes have good erosion resistance properties and support high traffic loads. Double-wall pipes are also called lightweight pipes that are suitable for an array of application purposes which include storm drainage, sanitary sewers, and underground works.

• Single-skin pipes

  Single-skin pipes are thin pipes made of polyethylene plastic. They are linear polymers that come with high density known as HDPE. These pipes are usually categorized as non-corrugated and corrugated pipes. Non-corrugated single-skin pipes have a plain internal and external surface. Single-wall pipes have an internal and external corrugated surface. Despite the difference in structure, the common factor is that single-skin pipes are made of a single skin of HDPE.

• Biological acid-proof pipes

  Biological acid-proof pipes are a specific category of hdpe irrigation pipes designed for applications with a high concentration of corrosive substances. Such tissues are resistant to high acidic or alkaline concentrations and come in handy in wastewater treatment facilities before disposal or underground chemical transport for manufacturing organizations.

• Perforated corrugated pipes

  Perforated SN4 HDPE pipes are embedded with perforations or small holes on their surface to allow permeability. These pipes help facilitate the movement of liquids into or out of the pipe and are often applicable in drainage systems to allow water and other fluids to flow in and out. These pipes are most preferable in groundwater control and agricultural field drainage.
