SS 310S / 310H High Temperature Refractory Pipes
25% Chromium and 20% Nickel austenitic alloy engineered for extreme thermal furnace, burner, and kiln environments.
ASTM A312 TP310S / TP310H Furnace & Heat Exchanger Pipe
Starlight Tubes is a specialized manufacturer and supplier of ASTM A312 TP310S / 310H high-alloy refractory stainless steel pipes. Combining 25% chromium with 20% nickel, Grade 310S exhibits remarkable resistance to oxidation, scaling, and thermal cycling in continuous service up to 1150°C in mildly cyclic conditions.
Our 310S/310H pipes are available in seamless and heavy-wall welded executions with full NDT certification. They are standard equipment in heat recovery steam generators (HRSG), cement kiln burners, petrochemical flare tips, annealing covers, and ore processing fluidized beds.
