What is a GI in plumbing?

What is a GI in plumbing?

Galvanised Iron (GI) Pipes are manufactured using mild steel strips of Low Carbon Steel Coils. The GI Pipes are generally used for distribution of treated or raw water in rural or urban areas. These pipes are cheaper, light weight and easy to handle.

What is GI fittings?

Galvanized iron fittings or GI fittings are malleable iron fittings used for connecting pipe ends. The Galvanized in the galvanized iron (GI) fittings imply that the iron has been coated in zinc so that the iron doesn’t corrode or rust.

What does FIP mean in plumbing?

Female Iron Pipe
F.I.P.: Female Iron Pipe. Describes an internal pipe thread end connection, verses external.

What does NPT mean in plumbing?

National Pipe Tapered Thread
The best known and most widely used connection where the pipe thread provides both the mechanical joint and the hydraulic seal is the American National Pipe Tapered Thread, or NPT. NPT has a tapered male and female thread which seals with Teflon tape or jointing compound.

Which is better GI or PVC?

More Durable – PVC Pipes are durable as compared to GI pipes. This is because GI pipe are not corrosion resistant and so they eventually rust. PVC pipes are corrosion resistant pipes. Compatible to hot & cold water – PVC pipes are not affected by warm water unlike GI pipes.

What is GI pipe class?

GI pipes (IS No: 1239; Part 1- 1990) are made from hot rolled coils of specified thickness. Medium- Class B: The pipe is marked in blue color for identification. 3. Heavy – Class C . The pipe is marked in red color for identification.

What is the difference between GI and MS pipe?

GI Pipe is “Galvanized Iron” Pipe. Material ms is mild steel and gi is galvanized steel that has been hot dipped . These days the pipe will likely be made from steel rather than iron.

What are CPVC fittings?

Chlorinated Poly (Vinyl Chloride) (CPVC) is a thermoplastic pipe and fitting material made with CPVC compounds meeting the requirements of ASTM Class 23447 as defined in ASTM Specification D1784. CPVC applications are for potable water distribution, corrosive fluid handling in industry, and fire suppression systems.

Are NPT and FIP the same?

As previously mentioned, NPT indicates the defined standard from ANSI – but many people use MPT/MIP and FPT/FIP interchangeably. FPT stands for Female Pipe Threads and FIP stands for Female Iron Pipe which both indicate a female fitting with NPT threads.

Does FIP connect to NPT?

FIP Female Iron Pipe (interchangeable with NPT) FIP, Female Iron Pipe, or Female International Pipe- Similar to FPT, FIP connect NPT pipe together with internal threads. MPT the threads are located on the outside of the pipe or fitting.

Why is NPT tapered?

The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other, as opposed to parallel/straight thread fittings or compression fittings in which the threads merely hold the pieces together and do not provide the seal.

Is NPT and MIP the same?

Yes, NPT (national pipe thread) has the same thread dimensions as an MIP (male iron pipe) and FIP (female iron pipe).

What is the ratio of Hopper throat to Hopper gate height?

In addition, a properly designed hopper produces a depth of discharged material that is slightly lower than the height of the hopper gate varying based upon the particle size and cohesion of the material. Uniform flow is achieved with the ratio of the hopper throat (T) and the hopper gate height (H) is 0.6. This ratio is expressed as T/H.

What is a drop bottom hopper?

Drop bottom hoppers, also known as bottom dump hoppers, are designed to minimize the hopper’s footprint while maximizing the storage space. Their design and features are different from a self-dumping hopper. How is a drop bottom hopper different? First, the forklift inserts are usually at the top of the hopper instead of the bottom.

What determines the size of the outlet of the hopper section?

The outlet of the hopper section must be large enough to prevent cohesive arches or stable ratholes from developing. The required outlet size depends on the cohesive strength and the bulk density of the powder. The cohesive strength is measured by shear-cell testing, as described in ASTM D-1628 [ 2] and D-6773 [ 3 ].

What is the T/H of a hopper feeder?

This ratio is expressed as T/H. Acceptable hopper design – Although a T/H of 0.6 is ideal, a T/H of 0.5 to 1.0 is acceptable. However, an acceptable design due to lack of bed depth, may necessitate a slightly larger feeder than would be required for a hopper that has an ideal design.
