DOUBLE WALL CORRUGATED (DWC) HDPE PIPES
(SIZE UPTO 1500MM)
[CODE NO.3193]
The Double Wall Corrugated Pipes (DWCP) manufactured by most companies are ideal for protecting telecom and electrical cables. Normally, the outer layer has corrugation and the inner layer has smooth and plain surface that gives the best of electrical and mechanical properties for cable ducting.
We shall hereby discuss the key features of DWCP pipes. To begin with, it needs to be well noted that these pipes are stronger than the GI, RGC, PVC as well as solid wall pipes. The DWCP pipes are known to have longer life span. These pipes are easy to transport and can be handled and installed due to light weight. These pipes have low installation costs and have excellent impact strength. These pipes are known to be flame retardant, UV resistant, leak proof, made from anti-rodent material, environmentally friendly, easy installation, flexible enough to adjust to various obstacles, and much more.
The DWCP pipes and fittings are manufactured via the use of HDPE polymer. The DWCP pipes are known to be resistant to various chemicals and gases which are produced because of putrefaction of different types of ingredients flowing in the system. Most manufacturers are known to use these pipes as per IS 16098 regulations and have a smooth internal surface as well as an external surface which is corrugated. It needs to be ell understood that the corrugated external surface provides assistance to higher loads, withstands soil movements as well as provides greater stiffness.
It is important to note the best of features of DWCP pipes, such as (a) Easy to store, handle and transport, (b) Depicting superior performance than RCC pipes, (c) abrasin resistant and corrosion, (d) Anti-rodent material, (e) Available in increased length of 6m that depicts less chances of leakage, and much more. The DWCP pipes have a variety of applications such as in underground drainage, industrial liquid waste, highway and road drainage, sewage, storm water and surface water drainage, and much more.
Most manufacturers are known to produce DWCP pipes that are environmentally safe to use and are chemically inert in nature. The DWCP pipes are normally corrugated and are used in underground cable protection and management of telecom and signal. These pipes ate known to be manufactured using virgin HDPE and are used as cable protection ducts and in sewer applications. The DWCP pipes are known to depict minimum friction and have smooth inner walls. These pipes are known to have maximum load bearing strength.
There are various advantages associated with the use of DWCP pipes. These pipes: (a) Depict good resistance to corrosion, (b) Depict good abrasion resistance, (c) Good impact and strength, (d) Smooth innerwall with minimum friction, (e) Availability with anti-rodent non-flame propagating properties, and much more.
Most manufacturers have successfully expanded their business in the market offering pipes that are environmentally safe and chemically inert. The pipes are used as a cable protection ducts for drainage as well as sewer applications. These pipes depict a very good resistance to corrosion.
