Why use HDPE for corrugated pipe? HDPE is the first choice for corrugated pipe, compared to concrete, clay or metal due to the following properties: Advantages due to Double Wall Corrugation: UV properties -> Non Flame Propagating Properties - Protection with resistance to flame propagating
-> Good balance b/w mechanical strength and product weight.
-> High chemical resistance against corrosion and abrasion making it suitable for use in saline / coastal areas.
-> Withstands high loads
-> Light weight thus making it easy to transportation, handle, and install.
-> Long term performance ( > 50 years) as compared to GI, RCC and PVC pipes.
-> Environmentally friendly.
-> High flexibility to take bends and curves around obstacles.
STIPL DWC Duct:
-> STIPL is India's leading manufacturer of DWC Ducts. The outer corrugated makes the duct light weighted and imparts excellent mechanical properties. The inner smooth wall makes the duct robust and facilities frictionless insertion of Cables / Ducts. These Ducts have high degree of static & dynamic load bearing capacity.
-> STIPL Ducts are manufactured from high quality HDPE granules, using only virgin raw materials ensuring products of high precision and international quality.
-> STIPL Ducts conforms to relevant international standards like BS EN 500086, Indian standards like IS 14930 Part - II and TEC spacification GR/DWC-34/01 Sep. 2007.
-> STIPL DWC ducts are widely being used by both government & private telecom companies, indian railways, public work departments, national highway authorities, development authorities, state electricity boards, airport authorities, power distribution companies, etc.
Applications:
STIPL (DWC) duct has the following application in Telecom & Electrical Networks :-
Telecom lt used as the main duct in main-duct / sub-duct network design.
-> Protection of ducts and optics fiber cables in city networks
-> Casing of copper cables.
-> used as a casing duct for simultaneous placement of quad cables and optic fiber cables along railway tracks.
Electrical
A. Protective casing of cables pole to pole application :-
-> Street lighting
-> Metro railway track lighting
B. Protective casing application of power cables / ducts / optic fiber cables :-
-> In city distribution networks
-> Across rivers
-> Along railway tracks
-> At road crossings-> traffic control-> areas with high traffic density-> signalling systems, control wires-> sensor systems-> water supply, gas supply-> protective pipes for mains connections-> power supply-> high and low voltage lines-> communication systems-> telephone lines, cable TV lines-> municipal utilities-> street lighting, street marking-> sewerage control systems
Range:-> Anti Rodent or Rodreplelancy Properties - To avoid rodent attacks -> Anti Termite properties - To avoid termite attacks

Quality Control & Testing
STIPL DWC Ducts for Ducts for Telecom / Railway / Road or similar applications applications are manufactured in accordance to relevant national & international standards like: IS 14930, BS EN 50086 and TEC spacification GR/DWC-34/01 Sep. 2007.
Every DWC duct undergoes extensive testing & inspection at STIPL's in-house laboratory & no duct leaves the works without the seal of approval from quality control team. The tests carried out are as follows:
S. No. Test Specification 1. Visual Appearance Inside surface should be smooth & No internal or external discolorations 2. Compression Strength When reaching the deflection of 5% the applied force shall be at least 450N. After the test, there shall be no crack allowing the ingress of light or water b/w the inside and outside. 3. Impact Test 5 kgs, load is dropped from 400mm height , No cracks / split 4. Bend Test During the test samples shall not flatten. bend the sample & pass a ball (95% of ID) through the bent sample.
