CARAT STRUCTURED WALL HDPE PIPE SYSTEM
Carat-structured wall HDPE pipe is a type of plastic pipe that is made from high-density polyethylene (HDPE). It is characterized by its spirally wound construction, which gives it a high degree of strength and flexibility. It is now considered the frontrunner in replacing traditional pipe system materials like concrete, CMP (corrugated metal pipe), and PVC (polyvinylchloride).
The standard length is 6 meters, making it easier to store, handle, and transport.
Pipes can be manufactured in different sizes – 600mm up to 3500mm – and in different ring stiffness’s
Where to use it?
WALL PIPE FEATURES AND BENEFITS
Carat Structured wall HDPE pipe offers a number of advantages over traditional materials, such as concrete and steel. It is lightweight, corrosion-resistant, and has a long service life. Structured wall pipe is also relatively easy to install, which can save time and money on construction projects.
Here are some of the benefits of using Carat Structured wall pipe:
- It is lightweight: Carat Structured wall pipe is much lighter than concrete or steel pipes, which makes it easier to transport and install.
- Corrosion-resistant: Carat Structured wall pipe is resistant to corrosion from chemicals and other environmental factors.
- Long service life: Carat structured wall pipe has a long service life (100 Years in Service), which can save money on replacement costs.
- Easy to install: Carat Structured wall pipe is relatively easy to install, which can save time and money on construction projects.
- Carat Structured wall pipe is a versatile and reliable material that can be used in a variety of applications. It is a good choice for projects where weight, corrosion resistance, and long service life are important considerations.
DEFLECTION IS SAFETY
The deflection of flexible pipes is controlled by the settlement of the soil. After settlement, traffic and other loads do not affect the pipe deflection anymore. When pipes are relatively more rigid than the soil, traffic and other loads have to be resisted by the pipe. Many years of practical experience have shown that flexible pipes (b) can resist traffic and other loads more effectively than flexural-resistant pipes (a) made of concrete or other rigid material. As shown in the drawing, the flexible pipes elude a selective strain by deflection. This means the surrounding soil absorbs this strain.
ELECTRO FUSION JOINT
The most preferred joint system, as the whole pipe system becomes a homogenous unit. A welding wire that is included in the socket or spigot is heated with the help of a special welding device, whereby the two pipe ends (socket and spigot) are joined together. The electro-fusion jointing technique is a very favourable, simple, and secure method to install pipes in even very narrow trenches in a short time. This technique of heat fusion joining for suspended piping, where space and pipe movement are limited, is heated internally by a wire coil at the interface of the joint.
ELECTRO FUSION JOINTING TOOLS:
Pipe Diameter
HDPE Easily manufactures through a semi-automated process; with sizes and internal diameter (ID) ranging from DN 600mm to DN 3000mm.
Load Bearing and Non-Load Bearing
1. NON-LOAD BEARING (NLB)- Are products which are intended for use and are capable of withstanding Dead/Earth Loads and Surcharge/Permanent Loads.
2. LOAD BEARING (LB) - Are product which are intended for used are capable of withstanding Dead/Earth Loads and Surcharge/Permanent Loads, and Live Loads (such as, but not limited to traffic Loads from heavy Vehicles.)
TEST RESULT FOR MECHANICAL & QUALITY
Structured Wall HDPE Pipe Embedment
The recommendations presented here detail how to install a dependable subsurface drainage or groundwater control system. Installation with proper backfill materials, compaction levels, and placement procedures are essential to achieve long term system performance.
These recommendations assume that the drainage designer used design criteria available from ASTM F449 and ASTM F2648 Trench Detail Under Pavement.
- Only native soil meeting class I, II, or III, as described in Table 1, are acceptable backfill materials.
- Class I materials can be dumped around pipe. Lightly tamp or knifed to ensure voids are eliminated.
- Non-cohesive sand, sand/gravel mixes and other Class II or III materials must be compacted to remove voids.
