Our products – tailor-made for your specific requirements
Solutions for Steam ReformerS+C offers a full range of products and solutions for Steam Methane Reformers (SMR), typically operated in hydrogen and synthesis gas plants. Reformers generally contain several hundred vertically oriented straight centrifugally cast tubes, commonly known as Reformer Tubes.
In order to maintain high levels of reliability, structural integrity and safety, operators would like to use the most advanced materials for their Reformer Tubes and associated Outlet components.
S+C always incorporates the latest improvements and innovations in the design of new tube materials. The very high degree of continuous improvements of S+C researchers in applying new features for the optimum and correctly balanced properties is the basis for S+C’s global leading position in this field.
Apart from Reformer Tubes, we are also specialised in the manufacturing and supply of ‘Hot’ Outlet Collectors, Tee-Pieces, Reducers, Cones, as well as other Outlet/Inlet Manifold components.
In addition to our products, we are pleased to offer our customers the foremost service and expertise in the industry, which includes aspects like non-invasive inspections, process analysis, remaining tube life assessment and top of the line materials among other things.
S+C supplies customized solutions for Steam Reformer – from fully fabricated reformer tubes up to outlet manifold components, such as centrispun tubes, tee-pieces and cones. Due to our continues efforts in material development and the comprehensive service provided we secure the highest reliability and efficiency for reformer furnaces in hydrogen and syngas plants.

New heat resistant materials for spun casting products
Optimized reformer tube configuration
The centrifugally cast materials working under severe operational conditions contain around 0.4 weight % carbon and therefore provide very good creep strength. Over the years, S+C developed special cast alloys with increased creep strength. This allows a reduction in tube wall thickness and at the same will increase the resistance by possible overheating. Thus providing a longer tube service life.
Modern alloys such as the HP- types (which are used since the early 1980`s), all contain a large amount of chromium and nickel. This contributes to strength and corrosion resistance at high temperature.
However, to obtain long-lasting high temperature strength it is important to balance the chemical composition of the alloy, since the key requirement is to achieve a most appropriate precipitation pattern.
S+C supplied Reformer Tubes in Centralloy® materials for many projects around the world and it is understood that tube life is expected to last longer and perform more reliable under adverse conditions.

Centralloy® G 4852 Micro R
The S+C special alloy with a unique creep strength for the challenges of steam reformersS+C generated a unique specification for the Centralloy® G 4852 Micro R material with substantially improved creep rupture strength compared to the conventional reformer tube materials.
In the latest generation of the HP-Microalloy material, the S+C alloy Centralloy® G 4852 Micro R, with small controlled additions of strongly carbide forming elements are causing during exposure to operating conditions the precipitation of very fine, nano sized particles which are uniformly dispersed in the matrix.
Centralloy® G 4852 Micro R
Benefits of Higher Creep StrengthThe alloy Centralloy® G 4852 Micro R is the result of a precisely balanced metallurgical composition – developed to deliver maximum performance in every application. Even today, it remains one of the most powerful materials on the market.
While maintaining the outer diameter of the reformer tube, the higher creep strength of Centralloy® G 4852 Micro R allows for a reduction in the minimum sound-wall thickness (MSW). This results in several advantages:
- Larger inner diameter, enabling higher catalyst volume and reducing the pressure drop in the tube
- Improved heat transfer – significantly enhancing the energy efficiency of the reformer furnace
- Higher resistance to the effects of potential overheating due to increased creep strength
