Serpentine coils
Provide bend radii, straight lengths, tube dimensions and the required coil arrangement.
Superheater coils and tube assemblies for boiler replacement and project supply.

Tube assembly photograph from GCB company materials; project configuration is subject to review.
Superheater surfaces transfer heat from flue gas to steam. For a replacement or new assembly, tube geometry, material requirements and connection interfaces must be considered together. Send your design drawings so the requested manufacturing scope can be reviewed.
Photographs illustrate component arrangements. Confirm the required application and configuration in your inquiry.
Provide bend radii, straight lengths, tube dimensions and the required coil arrangement.
Define the assembly envelope, support arrangement and connection locations.
Include existing drawings, photographs and any dimensional or material changes.
These are the inputs to provide, not fixed product ratings. Dimensions, materials and scope are confirmed against your project requirements.
| Tube dimensions | Outside diameter, wall thickness, bend radius and straight lengths |
|---|---|
| Materials | Required material grade and applicable material specification |
| Operating conditions | Steam pressure and temperature; relevant flue-gas conditions |
| Interfaces | Connection details, header arrangement and support requirements |
| Supply boundary | Individual coils, assemblies, quantities and required documentation |

Our workshop and company materials provide a starting point for discussing fabrication. Project-specific capability, processes and responsibilities are confirmed during technical review.
View our manufacturing page →Identify the component, interfaces and design requirements.
Agree specifications, quantities and supply boundaries.
Confirm inspections and documentation before production.
Agree transport requirements and the shipment schedule.
Material identification, bend geometry, weld inspection requirements and assembly dimensions should be agreed during technical review.
GCB’s Chinese Class A boiler component license covers serpentine tubes, headers, membrane walls and finned economizers. Other equipment inquiries require separate confirmation of applicable authorization and supply scope.

Send the latest drawings and revision information, material specification and quantities. The team will review the requested manufacturing scope before quoting.
Any material change needs technical review against design conditions and the applicable project requirements. Include the reason for the proposed change.
Provide the existing component drawings, photographs, interface measurements and required delivery date.
