Refinery and gas duty combines high temperature, hydrocarbons and a documentation regime. The engineering is usually straightforward; the qualification and certification are what take time.
Applications and the products that suit them
| Application | Product |
|---|---|
| Crude, naphtha and product transfer | Braided corrugated hose in 316L with armour guard |
| Burner and pilot gas connections | Braided corrugated hose in 321 for temperature |
| Loading arm and jetty connections | Braided corrugated hose with whip check and bend restrictor |
| Furnace and heater expansion | Hinged / gimbal joint in two- or three-hinge systems |
| Compressor suction and discharge | Pressure-balanced joint to protect the nozzle |
| Flare and vent lines | Axial expansion joint in 321 |
| CNG and CGD station connections | Braided corrugated hose high-pressure, DN6–DN25 |
| Hot gas ducting and exhaust | Interlock hose in 321 |
Specification notes for this sector
- 321 where sustained service exceeds 450 °C
- Third-party inspection and manufacturing data books are routine on this work
- Hydrogen service is assessed case by case — send us the conditions
What to send with an enquiry
Bore, medium, pressure, temperature, movement and both end connections. The reasoning for each is on how to specify an assembly.
