Galvanized Steel Pipe (GSP) is one of the most commonly used materials in plumbing, fire fighting, and industrial piping systems. It offers excellent corrosion resistance, durability, and strength — making it suitable for both indoor and outdoor installations. In this post, you’ll find essential details, specifications, and a free AutoCAD DWG download of GSP pipe and fitting details for engineering design.
What is a GSP Pipe?
A GSP (Galvanized Steel Pipe) is a mild steel pipe coated with a protective layer of zinc to prevent rust and corrosion. It’s commonly used for:
- Water supply systems
- Fire protection networks
- HVAC piping
- Industrial fluid lines
This zinc coating improves service life and ensures leak-free operation when installed with the right fittings and joint methods.
Types of GSP Fittings
Below are common fittings used with GSP pipes:
- Elbow 90° and 45° – for changing pipe direction
- Tee and Cross Fittings – for branching pipelines
- Reducer and Bushings – for connecting different pipe sizes
- Union and Coupling – for disassembly and maintenance
- Flanges – for easy joining and dismantling of pipe sections
Each fitting type follows standard dimensions such as BS EN 10255, ASTM A53, or ASME B16.9, depending on project specifications.
GSP Pipe Standard Sizes
Typical galvanized pipe sizes range from ½ inch to 6 inches, with Schedule 40 and Schedule 80 being the most common wall thicknesses.
