Can Cast Iron Soil Pipe be used in any type of building classification?
Yes. Cast iron is non-combustible and, therefore, has no restrictions as to the type of building it can be used in. Cast iron does not burn and doesn't give off toxic fumes or produce clouds of black smoke when subjected to heat. The same cannot be said for plastics, as they are combustible and have many restrictions placed on the within the building code.
Does Cast Iron Pipe rust?
Cast iron has unique corrosion-resistant characteristics. When cast iron is exposed to corrosion, the corrosion actually leaves behind an insoluble layer of corrosion products, which actually provide somewhat of a barrier against further corrosion. To find out the effects of specific chemicals or solutions, please contact your sales representative, and they will provide you with the information you require.
How long can you expect a Cast Iron DWV System to last in a building?
Cast iron will usually outlast the life of the building. Cast iron has been in use for centuries. One of the first installations was in Versailles, France, in 1664 to carry water some 15 miles to the palace and surrounding area. This system is still functioning after 300 years of service.
I use a combination of Cast Iron and copper on my installation. How do I reduce my cost?
Instead of using copper, which is used on the 2" and 1-1/2" pipe mostly, use 2" and 1-1/2" cast iron pipe. Not only is the cast iron less expensive in almost every case, more importantly, it reduces your cost on purchasing the tools required to install copper pipe. Cast iron is faster and easier to install. For more information on 2" and 1-1/2" pipe and fittings please visit the catalogue section of our website.
Is a Cast Iron drainage system quieter than other DWV materials?
Yes. Tests recently conducted in the Domtar Acoustical Laboratories by MJM Acoustical Consultants Inc. prove that cast iron is quieter. For a complete copy of this report, contact the Cast Iron Soil Pipe Association at 519-621-8141.
What's the difference between air-tight and water-tight covers?
Water-tight means that the frame has a gasket and four bolts or more in order to prevent infiltration.
Air-tight means that by inserting a rubber o-ring between the cover and the frame, we reduce odors (covers weight, even with a rubber o-ring, is not enough to make a cover airtight.)
What is the unrestrained pressure rating for SD 4000 Husky couplings and the Regular Duty Series 2000 No-Hub coupling?
Our couplings are designed for drain, waste and vent, a gravity system. They are not pressure rated. However, Husky SD 4000 couplings conform to US standard for Heavy Duty Couplings (ASTM C 1540) and are certified to the Canadian standard CSA B602. The specified test pressure in the ASTM C 1540 standard is 30 psi for 1 ½” – 5”, 27 psi for 6”, 15 psi for 8”, 9 psi for 10” and 6 psi for 12” and 15”.
Our Regular Duty Series 2000 No-Hub couplings are certified to CSA B602. The specified test pressure in the standards are 20 psi for 1 ½” – 5”, 18 psi for 6”, 10 psi for 8”, 6 psi for 10”, 12” and 15”.
These are laboratory tests and are not for use in the field.
What kind of deflection can I expect out of the Regular Duty Series 2000 and the SD 4000 Husky couplings?
Husky SD4000 deflection range is 5 degrees per lineal foot. Our Regular Duty Series 2000 couplings deflection range is for sizes 1.5”-4” is 5 degrees, 5”-8” is 3 degrees and 10”-15” is 1.5 degrees.
What is the required torque when installing Regular Duty Series 2000 and the SD 4000 Husky couplings?
The Husky SD 4000 couplings are designed to be installed with a pre-set torque wrench calibrated at 80-inch pounds to accommodate the 3/8” hex head screw. There is a very important torque sequence that needs to be followed when installing the Husky couplings. You can view an installation video by going to our home page and clicking on the installation video.
The Regular Duty Series 2000 No-Hub couplings are designed to be installed with a pre-set torque wrench calibrated at 60-inch pounds for sizes 1.5"-10" and 80-inch pounch for sizes 12"-15" to accommodate the 5/16” hex head screw.
What is the temperature rating on the Regular Duty Series 2000 Coupling and Husky SD 4000 couplings?
The gasket for both the Regular Duty Series 2000 Coupling and the SD 4000 Husky couplings are made of Neoprene. The maximum temperature that Neoprene will accommodate with continuous service is 203 degrees Fahrenheit with a maximum intermittent temperature of 212 degrees Fahrenheit.
Are your Regular Duty Series 2000 and SD 4000 Husky Couplings Fire Rated?
No-Hub couplings are not fire-resistance rated on their own but can be used as part of an assembly of materials with a fire-resistance rating.
These couplings are also listed to ULC S102.2-10 for a Flame Spread not greater than 25 and a Smoke Developed of not greater than 50
