Chlorination reactor manufacturers

Due to the highly corrosive nature of chlorine, the reactor must be constructed from corrosion-resistant alloys such as Hastelloy C276, Titanium, or Tantalum-lined steel. For lower temperature applications, Glass-lined (enamel) steel is a cost-effective alternative. You must verify that the material grade matches your specific chemical concentration and operating temperature to prevent stress corrosion cracking.

Pressure vessels must adhere to strict safety codes. Ensure the supplier provides certification for ASME Section VIII (U-Stamp) for the US market, PED 2014/68/EU (CE marking) for Europe, or GB150 for China. Additionally, look for ISO 9001 quality management systems and ATEX/IECEx certification if the reactor will be used in explosive atmospheres.

Chlorination is often an exothermic reaction, requiring precise thermal control. Evaluate the heat transfer area of the jacket (limpet coil or dimple jacket) and the efficiency of the internal cooling coils. Ensure the supplier provides thermal calculation sheets to prove the system can handle the peak heat load of your specific reaction.

To prevent toxic gas leaks, a double mechanical seal with a pressurized buffer system or a magnetic drive (sealless) is mandatory. The agitator type (e.g., hydrofoil, anchor, or gas-induction impeller) should be selected based on the gas-liquid mass transfer requirements. Specify the motor explosion-proof grade (Ex d IIB/IIC T4) based on your facility's safety zones.

Always mandate a Third-Party Inspection (TPI) by agencies like SGS, TÜV, or BV before the final balance payment. The inspection should include Non-Destructive Testing (NDT) such as Radiographic Testing (RT) for welds, Hydrostatic Pressure Tests, and Positive Material Identification (PMI) to confirm the alloy composition.

Focus on the Total Cost of Ownership (TCO) rather than just the purchase price. Negotiate for a longer warranty period (24 months instead of 12) and include a wear-parts package (gaskets, seals, O-rings) in the initial quote. For large-scale reactors, request milestone-based payments (e.g., 30% deposit, 30% after main body welding, 30% after FAT, 10% retention).

Reactors are often Oversized/Overweight (OOG) cargo. Ensure the supplier uses seaworthy vacuum packaging for sensitive components and heavy-duty steel cradles for support. Use FR (Flat Rack) or Open Top containers for shipping. Confirm that the supplier provides a detailed packing list and lifting diagrams to avoid damage during port handling.

Utilize professional B2B platforms like Made-in-China.com to verify the supplier's Audited Supplier status. Check their export history and whether they have experience shipping to your specific region. Always use Secured Payment services or Letters of Credit (L/C) for high-value industrial equipment to protect your capital.
