What is NP3 RCC pipe?
Non-Pressure RCC Hume pipes of class 2 are known as light-duty Hume pipes used for sewers, irrigation, and light traffic culverts. their thickness varies from 25 to 110 mm for 8cm dia and 2.2m dia respectively. for NP3 (medium duty) the thickness varies from 25 to 215mm. for 8cm dia and 2.6m dia respectively.
What is NP3 in Hume Pipe?
Types of RCC pipes. Hume pipes are available in three grades NP2, NP3, and NP4. The major difference between NP2, NP3, and NP4 RCC pipes is the load-bearing quality and flow. NP 2 RCC pipes are used for low duty load, NP 3 RCC pipes are used for medium-duty load, and NP 4 RCC pipes are used for heavy-duty load.
What is the difference between NP3 and NP4 pipes?
Basic Difference between NP2, NP3 & NP 4 is due to quality of product. The thickness is not main difference. NP 2 is used for normal flow and condition. NP 3 & NP 4 is used for heavy work for durability also prefer higher class.
What is NP4 pipe?
Non-Pressure RCC Hume Pipe is a premium product manufactured in different sizes varying by diameter and length of the individual piece. The NP4 heavy-duty, non-pressure pipes are one of a kind that can be used for irrigation, drainage and for cross drains with heavy culvert traffic frequency.
What is NP2 pipe?
‘Spigot and socket ended pipes shall be used for water mains, sewer, irrigation and culverts/cross drains Flush jointed (NP3 and NP4) and collar JOinted (NP2) pipes shall be used for culverts/cross drains only (see Fig. 1 and 2).
What is the test pressure of P1 class hummed pipes?
Explanation: Reinforced concrete pipes used in water supplies are classified as P1, P2. and P3 with a test pressure of 2.0, 4.0, and 6.0 Kg/cm2 respectively. For use on gravity mains, the working pressure should not exceed 2/3 of the test pressure.
What does NP3 stand for?
NP3 Coatings are a True Composite Coating of Electroless Nickel, Phosphorous and PTFE (Teflon). NP3 is a surface treatment for various metals and alloys that combines sub-micron particles of PTFE (Polytetraflouro-ethylene) with autocatalytically applied nickel/phosphorus.
What is full form of RCC?
The Full form of RCC is Reinforced Cement Concrete. RCC is a process when plain cement concrete which is a mixture of cement, coarse aggregate and fine aggregate is reinforced with steel bars.
What is Hume Pipe culvert?
A hume pipe is a concrete tube with reinforced bar. It was invented by the Hume brothers in Australia in 1910. A hume pipe is formed by pouring concrete into a formwork, and axially rotating it, and allowing it to compact using centrifugal force.
Which pipe has the property of brittleness?
More than 50,000 miles of cast iron pipe remain in the U.S. distribution systems . Cast iron pipe is relatively brittle and is subject to graphitization, a form of corrosion.
How is NP3 applied?
NP3 is a surface treatment for various metals and alloys that combines sub-micron particles of PTFE (Polytetraflouro-ethylene) with autocatalytically applied nickel/phosphorus. The result is an accurately applied, dry lubricated, low friction surface that is extremely hard and resistant to wear.
What is the diameter of Np3 pipe?
RCC NP3 Pipes. medium duty Reinforced concrete non pressure pipes. These are medium duty Reinforced concrete non pressure pipes with internal diameter of 300 to 2400mm and barrel wall thickness starting from 50 to 225mm.
What is the is code for RCC pipes?
