Review of Special No Hub Cast Iron Fittings

Before special no hub cast iron fittings, hub and spigot cast iron piping connected to fittings with hubs or bells. Plumbers joined them by melting lead or oakum and using specialized, unsafe and hard-to-use tools. Today, you have a variety of special no hub cast iron fittings to help you with any application in commercial, industrial, or residential construction.

Types of Special No Hub Cast Iron Fittings

  • Area drain
  • Backwater check valve
  • Bell trap
  • Ferrule plug
  • IPSGALV cent cap
  • Lead plug
  • Less speed flange
  • NH fittings iron body cleanout-tapped
  • Roof Drain

Uses

Use special no hub cast iron fittings for any construction drainage or pollution discharge systems.

Features

  • Flat and straight
  • High strength and density without defect
  • Easy to install and maintain
  • Long lifetime
  • Fireproof
  • Low noise rate

Standards and Specifications

  • No hub cast iron fittings:
    • CISPI 301 (Cast Iron Soil Pipe Institute)
    • ASTM A 888 (American Society for Testing and Materials)
  • No hub cast iron couplings:
    • CISPI 310 (Cast Iron Soil Pipe Institute)
    • ASTM C 1277 (American Society for Testing and Materials
    • ASTM C 1540 (American Society for Testing and Materials)

Conclusion

All 1 1/2 inch diameter and larger cast iron fittings for above and below grade soil, waste, vent lines, rainwater conductors, and storm drainage lines must comply with the above standards and specifications. When you source your special no hub cast iron fittings, look for the registered insignia that shows compliance.

Finally, check with your local jurisdictional code before installation to rule out local restrictions on hubless applications, particularly below grade.

Single Hub Cast Iron Fittings: What You Should Know

works well for water, waste lines, and venting in commercial, industrial, and some residential applications. Manufacturers cast it in a variety of sizes and styles, such as single-hub, double-hub, and no-hub. This post looks at single hub cast iron fittings a little closer.

What is a Single Hub Fitting?

A single hub cast iron fitting has a hub on one end and a spigot on the other. The spigot of one section fits into the hub of the next. You can use single hub fittings for pipe-to-fitting connections.

Advantages of Single Hub Cast Iron Fittings

Single hub cast iron fittings are very strong and durable for long-lasting performance. They offer quiet operation and fire resistance, particularly important for multi-unit buildings. Finally, single hub cast iron fittings are highly corrosion resistant and less expensive than copper.

Disadvantages of Single Hub Cast Iron Fittings

Beyond being somewhat heavy and cumbersome to work with, single hub cast iron fittings have few disadvantages unlike PVC or other materials.

Requirements for a Safe and Durable Drain, Waste, and Vent System

  • Non-combustibility
  • Strength and rigidity
  • Durability
  • Noise resistance
  • Ability to withstand traffic and trench loads
  • Ability to withstand temperature extremes
  • Low expansion/contraction
  • Abrasion resistance
  • Ex- and infiltration resistant joints
  • Corrosion resistance

Single hub cast iron fittings meet or exceed these requirements. When constructing buildings and facilities to last, single-hub cast iron fittings are the best choice.

Hubless Cast Iron Fittings and Their Uses

Standards organizations classify cast iron pipe and fittings used in the United States as either hub and spigot or hubless. Plumbers also refer to hubless pipe and fittings as no-hub.

What Are Hubless Cast Iron Fittings?

Cast iron is the industry standard material for sanitary and storm drain, waste, and vent applications in commercial and industrial construction. Plumbers used it for hundreds of years, and it is perfect for non-pressure applications where temperatures will not exceed 212 degrees Fahrenheit.

Hubless cast iron fittings connect no-hub pipes and fittings simply, quickly, and easily compared to hub and spigot couplings. In the past, hub and spigot cast iron piping required a variety of dangerous tools and methods to join. Hubless cast iron fittings are more in use today, but you can still find applications for hub and spigot.

Uses for Cast Iron Fittings

Cast iron fittings are the backbone of drain, waste, and vent plumbing systems, particularly in commercial and industrial applications. From a liability standpoint, avoiding substitutions for cast iron in your construction can be critical.

Any construction where fire-resistance is important should use cast iron. Also, cast iron reduces the noise of flowing water and waste in multi-unit buildings where sound travels. Cast iron has excellent crush strength and corrosion-resistance for buried applications.

How to Join Hubless Cast Iron Fittings

CISPI 301 requires companies manufacture cast iron pipe and fittings without a hub. To join pipes and fittings, a metal shielded hubless coupling telescopes over the plain ends. Then you torque to seal the joint.

Wall thickness of cast iron pipe and fittings varies depending on the size. There are also a wide variety of configurations for pipe sizes ranging from 1 1/2 to 15 inches.

Applications for Cast Iron Fittings

Cast iron is the premier piping material for sanitary and storm drains, waste, and vent (DWV) applications. It has served DWV applications for hundreds of years. Cast iron fittings are best used for non-pressure applications where temperatures will not exceed 212 degrees Fahrenheit.

In addition, cast iron pipes and fittings are the most durable DWV piping system available. Engineers and plumbers use them in all types of construction thanks to a high crush strength, fire resistance, and excellent sound-deadening performance.

What to Consider in Commercial Cast Iron Fitting Applications

Safety, reliability, and cost-effectiveness drive plumbing design. You also must include environmental quality, acoustics, and sound attenuation when planning commercial projects.

Value engineering can have negative effects. Excessive noise from the plumbing systems typically does not become an issue until tenants occupy the building. And at this late date, it is expensive to fix.

When to Consider Value Engineering

Identifying genuine money savings early in the design process allows you to find and rectify potential pitfalls in the design. For example, you cannot rectify unacceptably loud drain lines late in the construction process. But you can avoid them with the proper methodologies used early in the design process.

A Familiar Story

Consider a small university in the Midwest. The design engineer specified cast iron pipes for the drain lines in the dorm rooms. However, the plumbing contractor suggested they use PVC drain lines instead to cut costs. The general contractor and owner agreed.

After students moved into the building, however, they complained about the excessive noise when their dorm room neighbors flushed toilets or took showers.

There are two possible resolutions to this problem. Bore large holes in the walls and fit insulation or sound baffling around as much of the PVC pies as possible. Or remove the PVC piping and replace it with the original cast iron specified. Naturally, the school chose boring holes, which lead to significant extra time, money, and energy to carry out.

Conclusion

Dorm living is not the only fitting application where you should consider sound attenuation concerns. For example, the large hospitality industry, hospitals, convalescent facilities, nursing homes, multi-family homes, schools, prisons, and other commercial buildings should pay special attention.
