01 / SYNGAS & PETROCHEMICALS
From catalyst tubes
to complete assemblies.
Paralloy supplies reformer catalyst tubes and associated parts, including inlet and outlet pigtails and complete outlet manifold assemblies.
Inlet & outlet pigtails
Associated connections for the inlet and outlet sides of the reformer tube assembly.
Outlet manifold assemblies
Complete assemblies in both hot and cold collected configurations, matched to the reformer design.
ENGINEERED AROUND THE APPLICATION
Consider the whole assembly.
Discuss the tube, connecting parts and collection arrangement together. Drawings, operating conditions and the required material specification help define a suitable supply scope.

| Grade | Alloy family | Typical application & characteristics | Datasheet |
|---|---|---|---|
| H20 | 25/20 Cr/Ni · HK40-type | Cast heat-resisting alloy for catalyst reformer tubes and general furnace components, including hangers, supports and rollers. | |
| CR32W | 20/32 Cr/Ni · Niobium-bearing | Low-carbon cast alloy for reformer outlet headers and manifolds, and for collectors and transfer lines in pyrolysis plants. | |
| H39WM | 25/35 Cr/Ni · Microalloyed | Microalloyed heat-resistant steel for steam reformer furnaces and heavy-duty pyrolysis cracker coils, combining creep strength and carburisation resistance. | |
| H39WMR | 25/35 Cr/Ni · Low-silicon microalloy | A lower-silicon development of H39WM for reformer furnaces, with enhanced creep strength for demanding tube duties. | |
| H39WM+ | 25/35 Cr/Ni · Enhanced microalloy | Developed from H39WM for steam reforming, with improved creep-rupture strength and carburisation resistance through chemistry and process optimisation. |
Grade summaries are an overview of the supplied manufacturer literature. Confirm the current datasheet revision, chemistry and design values with DPU and Paralloy. Allowable temperature, pressure, wall thickness and service life depend on the selected material, component and application.
