What kind of bolt is used in a cast iron mechanical joint flange?
Bolts are hex-head machine bolts with regular or heavy hex nuts as specified. Studs with one hex nut each are required for tapped flanges.
Is flanged pipe restrained?
Flanged pipe is generally specified for aboveground service for water, wastewater, air, oil and other liquids where rigid, restrained joints are needed. The underground use of the flanged joint is generally not recommended due to the rigidity of the joint and as noted in appendices of appropriate ANSI/AWWA standards.
How far can ductile iron pipe span?
The beam strength of ductile iron pipe, along with the capability of certain AMERICAN joints, allows the installation of clear spans of up to 48′ or more in sizes 6”* – 64”.
What is a MJ tee?
MJ stands for Mechanical Joint. It is a type of compression joint designed for underground connection for pipe, valves and fittings. The components are comprised of a mechanical joint bell on the pipe, valve or fitting, and a mechanical joint gland, gasket and set of tee-head bolts and nuts which are supplied loose.
How much can you deflect ductile iron pipe?
Maximum deflection is 15° per joint in sizes up to and including 24-inch pipe; in sizes 30-inch and larger, maximum deflection varies from 12° to 15°.
Can you weld a flange on ductile iron pipe?
Ductile Iron can be welded successfully to produce welds that have mechanical properties comparable to those of the base iron. As with any base material, the success of welding Ductile Iron depends on suitable equipment, correct procedures, qualified welders, and effective quality control procedures.
What do you weld ductile iron with?
Gas welding can be used to join Ductile Iron components by the creation of either fusion or diffusion bonds. Gas fusion welding is a well established welding method for joining Ductile Iron. The process simply involves fusion of the base metal and filler rod by heat generated from an oxyacetylene flame.
How much does ductile iron pipe weigh?
Weight Of Thickness Class Ductile Iron Pipe And Contained Water
|Thickness Class||Nominal Size Inches||Total (Pounds Per Foot)|
Why are compact ductile iron fittings?
Why Compact Ductile Iron Fittings? Compact Ductile Iron Mechanical Joint Fittings are manufactured from a high strength, impact resistant ductile iron that offers a great margin of safety against service fail-ures and provides vastly increased resistance to breakage caused by rough handling during shipment and installa-tion. Compact fittings are manufactured from ductile iron
How much does a ductile iron pipe cost?
ElectrosteelUSA.com offers ductile iron products that range anywhere from as little as $160 to as much as $22,000 . For example, a cement lined, size 3″, length 1’0″-17’6″, wt. 26-253 (FxPE) retails for $161 to $1,375 , while the Tnemec Series 431 perma-shield PL lined, size 10″, length 1’0″-17’6″, wt. 74-721 (FxPE) retails for $427 to $3,419
What are the specifications of ductile iron pipe?
A ductile iron pipe is created from cast iron that has undergone treatment while in a molten state to enhance its relative malleability, rendering it more resistant to damage typical with traditional cast iron. Ductile iron pipes range in diameter from 3″ to 54″ in 20′ lengths.
What are ductile iron fittings?
Ductile iron is used for much of the same type of items as ductile iron, as it is also very strong and workable (or ductile). The uses for ductile iron include pipe fittings, industrial piping, liquid fittings, strainers, and more. As mentioned before, ductile iron is cheaper to produce.
