01 · STRAIGHT SPIRAL DUCT

Choose Your Forming System

Compare the two spiral duct routes using your actual diameter list and material mix.

Material & Thickness
Actual grade, sheet thickness and surface requirements.
Diameter Portfolio
Recurring diameters and the supplied tooling or molds.
Changeover & Cutting Scope
Confirm setup, cutting, discharge and material handling.

Select one straight-duct forming system. Included molds, tools and complete utility requirements are confirmed for the quoted package.

02 · SEGMENTED ROUND ELBOW

A Connected Equipment Route

Choose one cutting route and one elbow-forming option. Rolling and spot welding sit between them.

STEP 01

Plasma or Laser Blank Cutting

These are alternative blank-cutting methods. They are not two compulsory machines in the same route.

Plasma Cutting Machine

Plasma Cutting Machine equipment reference

Select process conditions for the actual sheet grade, blank geometry and accepted edge quality.

View Plasma Cutting
Conceptual developed sheet-metal blank for a round elbow segment

Develop the fitting blank first

The finished elbow diameter, angle, radius and segment layout define the blank. Agree the cut drawing before rolling.

STEPS 02–03

Shape and Prepare the Segments

Review the rolled shape and specified joint before the final elbow-forming operation.

Plate Rolling Machine

Plate Rolling Machine equipment reference

Roll the cut blank to the required segment curvature. Confirm grade, thickness and working width.

View Plate Rolling

Spot Welding Machine

Spot Welding Machine equipment reference

Prepare the specified segment joint with suitable overlap, electrode access and settings.

  3. Single rolled segment with a prepared longitudinal jointPrepared segment joint

This row shows single prepared segments. A complete elbow is formed in the next stage. Spot welding alone does not establish a continuous sealed joint; agree the finished joint and inspection requirement.

STEP 04

Choose Your Round Elbow Machine

Match material, diameter, elbow angle, radius and joining tooling to the finished fitting.

03 · COMPLETE EQUIPMENT PACKAGE

Confirm the Workshop Scope

Straight duct forming and elbow fabrication are separate jobs; select the equipment that belongs in your project.

Straight duct route

One spiral duct system, matched diameter tooling or molds, and the confirmed cutting and handling scope.

Elbow route

One blank-cutting method, plate rolling, spot welding and one electric or hydraulic elbow machine.

01

Material & Thickness

Specify grade and the actual thickness range.

02

Duct Diameter Range

List the recurring straight-duct and fitting sizes.

03

Elbow Angle & Radius

Provide segment layout and complete geometry.

04

Joint / End Connections

Agree seam, mating fit and finished joint.

05

Batch Mix & Utilities

Define recurring orders, site power and handling.
