Fabrication of Industrial Ducting and Chutes
JCMARVEL Engineering and Trading LLP executes the fabrication and supply of Industrial Ducting and Chutes for various industrial applications.
Our Fabrication Processes
1. Detailing
Based on your design, we pepare the shop fabrication drawings and as built drawings for the ducting.
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, rolling, 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

8. Delivery
Loading & shipment to client on third party transport, or loading in client arranged transport vehicles.
Shapes & Mounting
Duct shapes: These vary as per application and end user needs. Typical ducts feature components that are square, rectangular, cylinderical, conical, combo of above with connecting transition elements etc.
Thickness: While most Ducts have low/medium wall thicknesses, chutes for material transfer feature higher thicknesses or even internal wear plate linings.
Lengths & Orientation: These are highly customised as per the customers specific apllications, and feature vertical components, horiztonal components and inclined components.
Typical Specifications
Materials: Steel and Stainless Steel Ducts and Chutes are manufactured from a variety of carbon steels and stainless steels. Usual grades are mild steel, A36, SA516, SS304, SS304L, SS316, and SS 316L.
Applications: Ducts are connected to various plant process equipment to serve as inlet or outlets for gases, hydrocarbons, and air etc, while chutes are usually used in discharge of different media.
Media / Fluid Types: Chutes are mainly used in material transfer, while ducts may be used for conveying a variety of media like hydrocarbons, flue gases, air etc.
