Piping and structural fabrication is the process of cutting, bending, and assembling pipes to form a specific piping system for a variety of industrial and structural uses. This process consists of several steps, including the design and planning phase, material selection based on the type of fluid and the conditions it will be exposed to, cutting the pipes to the required length, bending them to the necessary angles, and finally welding or joining them together to form a continuous path for fluid transportation. The quality of piping fabrication is crucial for assuring the integrity, safety, and efficiency of piping systems, particularly in industries such as oil and gas, chemical processing, and electricity production.
Products constructed from steel pipes that have been specially crafted or adjusted to satisfy particular specifications are referred to as steel piping fabricated products. These goods may consist of:
1. Pipe fittings (elbows, tees, couplings, etc.).
2. Pipe spools.
3. Flanges.
4. Valves.
5. Pipe supports and hangers.
6. Custom pipe assemblies.
7. Pipe racks and skids.
8. Boiler tubes and components.
9. Heat exchanger tubes and components.
10. Pressure vessel components.
11. Tank Fabrication.
Pipe Rolling and fabrication.

1. Oil and gas
2. Power generation
3. Chemical processing
4. Water treatment
5. Food processing
6. Pharmaceutical
7. Construction
8. Shipbuilding
These products are made using various techniques, such as:
1. Cutting (sawing, shearing, etc.)
2. Welding (MIG, TIG, ARC, etc.)
3. Bending (hot and cold)
4. Forming (rolling, pressing, etc.)
5. Machining (drilling, milling, etc.)
