What is the difference between AWWA C110 and C153?
Description: Today, standard compact fittings C153 are commonly used in place of full Body fittings C110. They are designed to be to be more lightweight and more economical to use while providing better flow characteristics.
Is standard for ductile iron pipe?
ANSI/AWWA C151/A21. 51 — American National Standard for Ductile-Iron Pipe, Centrifugally Cast, for Water. ANSI/AWWA C153/A21. 53 — American National Standard for Ductile-Iron Compact Fittings, 3-inch through 24-inch and 54-inch through 64-inch, for Water Service.
What is the wall thickness of ductile iron pipe?
This value also referred to as the Minimum Manufactured Thickness, is used to select the proper pipe wall. The standardized Service Allowance for all diameters of Ductile iron pipe is 0.08 inches.
What is NSF 61 certified?
Standard Overview As an approved standard of the American National Standards Institute, NSF/ANSI 61 is the legally recognized national standard in the United States for the human health effects assessment of drinking water contact materials, components and devices.
Is Cast Iron NSF approved?
NSF International announced that The Cast Iron Soil Pipe Institute (CISPI) member companies’ soil pipe and fitting products have been certified. Cast iron soil pipe and fittings are used in building construction for sanitary and storm drain, waste and vent piping applications.
What is Tyton joint?
The TYTON JOINT is simplicity itself. A single rubber sealing type joint that employs a circular rubber gasket assures a tight, permanent seal. This “push-on” type joint is simple to assemble and fast to install. Eliminates the need for bolts, nuts and glands.
What is in ductile iron?
Ductile iron—also referred to as spheroidal or nodular iron—is actually a group of irons that exhibit high strength, flexibility, durability, and elasticity due to their unique microstructure. Cast ductile iron normally contains over 3 percent carbon; it can be bent, twisted, or deformed without fracturing.
How long does ductile iron pipe last?
A: Properly designed and installed Ductile Iron Pipe systems could easily have a life expectancy of more than 100 years. Unlike other pipe materials, the physical properties of Ductile Iron Pipe do not change with age.
Can you bend ductile iron pipe?
Ductile Iron has minimum strength requirements of 60,000 psi tensile strength, 42,000 psi yield strength, and 10 percent minimum elongation. Has Great Beam Strength Ductile Iron will bend or give considerably before it will ultimately fail.
