Pipe bridge fabrication — steel structures for overhead pipeline crossings
Pipe bridges are elevated steel structures that carry piping over roads, rail lines, existing plant areas, or open ground between two parts of a facility. They combine trestle or portal supports with longitudinal trusses or beams sized for piping weight, thermal movement, and maintenance access. Sun Corporation fabricates pipe bridges in our Hyderabad workshop and erects them with our own site teams across India.
Fabrication scope
We supply the structural steel only unless the contract includes pipe shoes, guides, or secondary supports shown on the structural drawings. Shop work includes cutting, drilling, assembly, coded welding to qualified WPS, NDT per the ITP, blast/prime or full painting, and dispatch in logical erection sequences.
| Element | Notes |
|---|---|
| Supports / bents | Built-up or rolled sections; base plates and anchor bolt templates |
| Longitudinal members | Trusses, plate girders, or composite beams per design |
| Bracing | Vertical and horizontal bracing for wind and seismic loads |
| Access | Maintenance walkways and platforms when shown on GA |
| Codes | IS 800:2007; IS 2062 material; project-specific corrosion protection |
Coordination with piping and civil
Pipe bridge erection usually follows foundation completion and precedes piping stress finalisation on site. We review lift plans and bolt-up sequences with the EPC construction team before dispatch. For related rack work in the same contract, see pipe rack fabrication.
