Soundproofing Qualities of Cast Iron Pipe and Fittings
The use of neoprene gaskets and hubless coupling with cast iron pipe and fittings significantly reduces noise and vibration. Because of the composition and structure of cast iron, sound is muffled rather than transmitted or amplified. The neoprene separating the pipe from the fitting suppresses contact-related sound.
Economic Advantages of Cast Iron Pipe and Fittings
The properties of cast iron soil pipe and fittings and the various joining methods demonstrate that cast iron affords a number of economic advantages. These advantages include performance, versatility, low cost installation, and product availability.
Performance of Cast Iron Pipe and Fittings
The performance and durability of cast iron pipe and fittings are superior to any other product used for sanitary and storm drain, waste, and vent piping. When it comes to performance, cast iron has no equal.
Versatility of Cast Iron Pipe and Fittings
Cast iron pipe and fittings are the most versatile sanitary and storm drain, waste, and vent piping material on the market. They are available with a variety of joining methods, allowing for efficient installation, both above and below the floor and underground. They are also adaptable for use in all types of building construction.
Low Cost Installation of Cast Iron Pipe and Fittings
Cast iron pipe and fittings offer the advantages of low-cost installation.
- A compression gasket joint and hubless coupling joint can be made quickly and efficiently.
- Ten-foot pipe reduces the number of joints in a plumbing system
- Reduced waste
- Smaller outside diameter fits well within conventional 2 x 4-foot stud walls as compared to plastic pipe.
- Ease of fabricating in your shop
Product Availability of Cast Iron Pipe and Fittings
Orders can be filled on short notice. Cast iron pipe and fittings are readily obtainable from our Foundry in Charlotte, NC.
Types of Cast Iron Soil Pipe and Fittings
Cast iron soil pipe used in the U.S. is classified as either Hub and Spigot or No Hub, or Hubless.
- Hub and Spigot pipe and fittings have hubs into which the spigot (plain end) of the pipe or fitting is inserted. The joint is sealed with a rubber compression gasket or molten lead and oakum.
- Hub and spigot pipe and fittings are available in two classes of thickness: Service (SV) and Extra Heavy (XH).
- Hubless cast iron pipe and fittings are manufactured without a hub in accordance with ASTM A 888 or CISP 301, and are available in 1 ½” through 15” sizes.
- The method of joining hubless pipe and fittings utilizes a shielded hubless coupling which consists of a neoprene rubber sleeve and a stainless steal shield that slips over the end of the pipe and fittings and is tightened with a torque wrench.
Cast Iron Pipe and Fittings' Resistance to Abrasion
Cast iron pipe and fittings are highly resistant to abrasion from sand, gravel, garbage disposal residue, dishwasher discharge, and debris carried in suspension along the lower portion of the sewer or drain.
Uses
Cast iron soil pipe and fittings are used primarily in building construction for sanitary and storm drain, waste and vent piping applications.
In buildings, cast iron pipe and fittings are installed within the partitions and serves the tub, lavatory, and water closet fixtures. The main line in this assembly is the cast iron soil stack, which runs vertically from the building drain up through the structure and through the roof. Waste lines are connected to this main soil stack, and vent lines may also be tied in at a point above the highest fixture. In some installations, vent lines are connected to a separate vent stack, which acts as the main source of air to and from the roof.
Cast iron soil pipe and fittings are also used for storm drainage from roofs, yards, and courtyards in building construction. At present, cast iron soil pipe and fittings are the preferred material in high-rise structures for drain, waste and vent and sewer – without concern for building height.
Requirements for a Safe and Durable Drain, Waste and Vent System
A safe and durable drain, waste and vent piping system requires that the material possess the following important characteristics:
- Strength and rigidity
- Durability exceeding expected life of building
- Quiet operation, resistant to noise transmission
- Noncombustible and does not contribute to the spreading of flames
- High crush strength and ability to withstand traffic and trench loads
- Ability to withstand temperature extremes
- High corrosion resistance
- Low coefficient of expansion and contraction
- High abrasion resistance
- Leak-free joints that resist infiltration and exfiltration
Performance
For hundred of years, cast iron has been the premier piping material throughout the world for drain, waste and vent applications. Unique corrosion resistance characteristics make cast iron pipe and fittings ideally suited for plumbing applications. When exposed to corrosive conditions, cast iron leaves behind an insoluble layer of corrosion that provides a barrier to additional corrosion.
