What is hubless cast iron pipe used for?
Scope: This specification covers hubless cast iron pipe and fittings used in sanitary drain, waste, and vent (DWV), sewer, and storm drainage applications. This system is intended for use in nonpressure applications.
What is XH cast iron?
Extra Heavy Cast Iron Pipe is a thick hub and spigot soil pipe made out of cast iron. It can also be referred to bell and spigot pipe. In other versions it can be hubless, and known as no hub pipe. Each joint is connected using molten lead and oakum, or neoprene compression gaskets.
What is hub and spigot piping?
The end connection of a fitting that is to be assembled into another fitting is called the “Spigot.” The spigot end of a fitting has the same outside diameter as pipe. The common female connection of PVC fittings is referred to as the socket or hub, and the spigot end of a fitting can be inserted into a Hub or Socket.
How cast iron pipe is connected?
There are generally three methods used for joining cast iron soil pipe. Hub and spigot cast iron soil pipe may be joined by the compression gasket or a caulked joint. Hubless cast iron soil pipe are joined by using a hubless coupling.
Are Fernco couplings code?
It is my understanding that flexible PVC couplings (e.g. Fernco) meet the definition of Mechanical Joint in the international residential code. The 2015 IRC prohibits the use of Mechanical Joints on PVC couplings above ground “unless otherwise approved”.
Can you bury a no hub coupling?
Mission and husky couplings are allowed underground here, no hubs aswell. Have to fasten to 60ibs.
What is a hub fitting?
Hub – a type of DWV fitting end that allows pipe to slide into the end. This standard allows NPT threaded fittings to fit together in a water-tight seal.
What is the difference between spigot and socket?
A socket is a fitting that simply goes over the end of a pipe. A spigot fits inside a socket, so it is the same size around as regular pipe. When you need to attach a fitting to another fitting, you use a spigot end. In their function, sockets are the female and spigots are the male.
Where does the hub go in a hubless wheel?
In a so-called ‘hubless’ wheel, the hub is actually a large thin ring that fits just inside the rim of a large bearing with the tire on its outside. The inner ring itself attaches to the vehicle’s frame.
What’s the difference between no hub and hubless pipe?
Hubless pipe and fittings are also referred to in the plumbing industry as no-hub. Hubless cast iron soil pipe and fittings are manufactured without a hub, in compliance with CISPI 301.
Can a hubless wheel be used on an electric bike?
With such an unconventional design, one of the challenges is getting power to the rear wheel. This can be done through a specially adapted chain or belt. After four years of development, Reevo Bikes has unveiled its hubless electric bike.
Who was the inventor of the hubless wheel?
The concept of the hubless wheel was in fact invented by Franco Sbarro (who has built a variety of working hubless wheel vehicles, including at least two motorcycles and a car, the 1989 Sbarro Osmos), and patented by Globeholding of Geneva.
