Fabrication of Headers and Jacketed Systems
JCMARVEL Engineering and Trading LLP executes the fabrication and supply of Headers and Jacketed Systems for various industrial applications.
Our Fabrication Processes
1. Detailing
Based on your design, we pepare the shop fabrication drawings and layouts for hoppers, bins & silos.
2. Procurement
Sourcing materials from reliable supply sources, matching Mill Test Certificates and tracking.
3. Fabrication
Various shop fabrication processes like layout generation, cutting, grinding, bends, edge preparation etc.
4. Assembly
Fabricated parts are fitup and assembled for welding in a phased manner for welding commencement.
5. Welding
Strict conformity to WPS / PQR. Use of reliable experienced welders to produce sound weld joints.
6. Testing & NDT
As per project ITP, stagewise inspection, DP, MPT, UT, RT, Dimensional Inspection Tests etc. are performed.
7. Coatings
Blasting & Painting of Steel Headers/Jacket parts as per NACE / SSPC. Passivation and/or Pickling for SS items.
8. Delivery
Loading & shipment to client on third party transport, or loading in client arranged transport vehicles.
Shapes & Parameters
Jacketed Systems: Both Piping and Tanks can be jacketed for purposes like cooling. Double walled containment tanks differ since they have no heating/cooling media in circulation.
Header Piping: These may be jacketed or non-jacketed depending on application needs, and sizes may range from small headers to larger headers for plant equipment.
Pressure Test: Jacketed systems are subjected to a pressure test to ensure that circulating media does not leak under operational pressure.
Typical Specifications
Materials: A variety of carbon steels and stainless steels grades can be used in fabrication. Usual grades are mild steel, A36, SA516, SS304, SS304L, SS316, and SS 316L.
Applications: Headers are used in plant equipment like reactors or distribution systems and may be jacketed/non-jacketed, while jacketed tanks used for heat transfer of fluid in process tanks.
Media / Fluid Types: Can handle various media and fluids like chemicals, hydrocarbons, effluent gasses, fuel, oil, air, water etc.
