Reactors & Pressure Vessels places specific demands on the alloys that serve it. Jiangsu DZX Alloy supplies Hastelloy, Monel, Incoloy, Titanium & titanium alloys for this duty, combining 24+ years of precision-alloy manufacturing experience with an ISO9001 triple-inspection system, a 12,000 m2 self-owned factory and full batch traceability. Within Chemical Processing, reactors & pressure vessels combines these requirements in its own way.
Reactors, heat exchangers, valves and pumps handling strong acids and alkalis live or die by material selection: it determines equipment life, plant safety and product purity. Jiangsu DZX Alloy supplies Hastelloy (C-276, C-22, B2, B3), Monel (400, K500), Incoloy (825, 925), Inconel 625, titanium alloys and thermocouples for process monitoring.
General Requirements for Reactors & Pressure Vessels
- Corrosion resistance matched to the specific medium: oxidising, reducing, chloride-rich or acid.
- Verified chemistry: PMI-ready material with documented alloying elements (e.g. Mo/W in C-276).
- Fabrication reliability: wall-thickness tolerance for tube expansion, welding and forming.
- Contamination control: material purity that protects product quality.
- Supply-form fit: materials must be available in the forms fabrication requires — typically plate0.5-100mm, tube OD3-300mm / wire, tube, plate, bar / wire0.15-7.5mm, strip, plate, bar.

Application Scenario Deep Dive: Reactors & Pressure Vessels
The costliest chemical-plant material failures rarely come from wrong grade selection — they come from unverified grade identity. PMI-verified deliveries with documented alloying content turn “labelled C-276” into “proven C-276”, which is the difference between a corrosion barrier and a liability.
When C-276: Cr 14.5-16.5%, Mo 15-17%, W 3-4.5% governs the duty, Hastelloy is the typical first call; Monel is preferred where 400: Ni ≥63%, Cu 28-34% matters more. Jiangsu DZX Alloy’s engineering team can review your duty conditions and confirm the grade, condition and tolerance before ordering.
Reactors & Pressure Vessels does not operate in isolation: within Chemical Processing it sits alongside Heat Exchangers & Condensers, Valves, Pumps & Fittings, Piping & Transfer Lines, and material choices made here often share grades, documentation and inspection practice with those duties. Reviewing the neighbouring application pages is the fastest way to see where specification boundaries lie.
