High‑Temperature Alloy Piping for Chemical Furnace
Application Scenarios
In the petro‑chemical, specialty chemicals, and advanced materials sectors, furnace‑integrated pipelines must endure continuous exposure to temperatures above 800 °C while resisting aggressive corrosive media. Our high temperature alloy piping for chemical furnace is engineered for:
- Steam cracking units where superheated steam transports reactants at 950 °C.
- Oxidation and calcination furnaces handling halogen‑containing acids.
- Catalyst regeneration loops that cycle between 800 °C and 1000 °C under high pressure.
- Batch reactors equipped with induction heating, requiring rapid thermal cycling.
Selecting the right alloy and design minimizes unplanned shutdowns, extends furnace life, and protects downstream equipment from metal‑borne contaminants.
Product Overview
Our high temperature alloy piping for chemical furnace is supplied as seamless or welded tubes, flanged assemblies, and custom‑fabricated manifolds. Each component is produced from alloys selected for superior creep resistance, oxidation stability, and compatibility with the most aggressive process gases (e.g., chlorine, fluorine, sulfur compounds). The product line covers standard diameters from 1 in. to 12 in. and can be tailored to meet specific pressure classes up to 250 bar.
Our engineering team works directly with OEMs and EPC contractors to deliver pipework that integrates seamlessly with furnace refractory systems, heat exchangers, and control instrumentation.
Typical Specifications (customizable per order)
| Alloy Grade | Diameter (in.) | Wall Thickness (mm) | Maximum Continuous Temp (°C) | Design Pressure (bar) |

Full Certification Portfolio – Products are manufactured under ISO 9001 and ASME‑Section III, and are CE‑marked where applicable. Documentation for API‑610 and PED compliance is provided on request.
Rapid Lead Times – Standard sizes ship within 15–45 days after purchase order confirmation; custom lengths or special heat‑treatments are accommodated within a 60‑day window.
End‑to‑End Engineering Support – Our in‑house metallurgists assist with stress‑analysis, finite‑element modelling, and on‑site welding procedures to guarantee flawless integration.
FAQ
What is the minimum order quantity (MOQ) for custom alloy pipe?
For standard dimensions the MOQ is one bundle (typically 10 m). Custom alloys or special heat‑treat cycles start at a 5 m length per grade, ensuring cost‑effective tooling.
Can the piping be tailored to non‑standard diameters or wall thicknesses?
Absolutely. Our rolling and extrusion facilities support diameters from 0.5 in. to 24 in. and wall thicknesses from 2 mm up to 30 mm, all verified by ultrasonic thickness testing.
What is the typical lead time for a fully engineered furnace loop?
Once the engineering drawing is approved, standard alloy pipe is delivered in 15‑45 days. For fully fabricated manifolds, flanged assemblies, and heat‑treated sections, the overall lead time ranges from 45 to 60 days.
Do you provide warranty or post‑sale technical support?
All products carry a 12‑month material warranty against manufacturing defects. In addition, our technical service team offers on‑site troubleshooting and performance validation at no extra charge during the warranty period.
