GI pipes are available in a variety of sizes and thicknesses to meet a range of needs. The nominal bore (NB) diameter, which represents the pipe's inner diameter, is commonly used to indicate size. Sizes between 12 inch and 6 inches or more are typical.
There are two main classifications of these pipes: medium (M) and heavy (H). The pipe's wall thickness and related strength are determined by the class. While heavy-class GI pipes are appropriate for more demanding or high-pressure applications, medium-class GI pipes are utilised for common purposes.
It's crucial to use the right installation methods while working with GI pipes, including securely attaching the pipes using threaded connections or welding. Regular upkeep and inspections are also required to look for any indications of corrosion or harm to the zinc covering.
It's important to note that although GI pipes are frequently utilised, there are other pipe materials including PVC, CPVC, and stainless steel pipes that are also available. The particular use, the climate, and the budget all have a role in the choice of pipe material.
