High-temperature pipework & fittings
Hot gas lines at 500–900 °C grow, creep and scale. We specialise in designing and building the whole run: pipework, expansion joints, supports and split flanges that stay tight through thermal cycling.
| Service temperaturetypical | 500–1,100 | °C |

Typical = indicative range. Every unit is sized to your material and duty, and confirmed on the quote.
High-temperature pipework, designed as a system
Pipework design
Routing, stress and thermal growth worked out before fabrication.
Expansion joints
Bellows and expansion joints selected and fitted to absorb movement.
Pipe supports
Fixed, sliding and spring supports designed for hot lines.
Split flanges
Our own split flange design for access and maintenance without cutting.
Fittings and spools
Bends, reducers, tees and spools in 253MA, 310S and 800HT.
Refractory-lined lines
For the hottest duties and large diameters.

What is the lead time?
Typically 6–16 weeks from an approved general arrangement drawing.
Can you fit it to our existing plant?
Yes. We survey the site, draw the interface and build to suit your flanges, heights and controls.
Do you install and commission?
Yes. We deliver, install, wire, test and commission, or supply for your own team to fit.
