The Frame 9F DLN combustion liner provides the inner combustion passage within the designated dry low NOx system. Its cylindrical body and formed end sections establish the geometry between the head-end hardware and downstream combustion connections. OBT supports custom manufacturing projects for this component family, with the exact configuration established through technical review.
The inlet profile, formed body sections, outlet retention region and specified internal surface requirements are reviewed together. OBT develops the liner manufacturing definition around the selected 9F DLN revision and its mating head-end and downstream interfaces.
OBT combines high-temperature-alloy sheet-metal fabrication with forming, laser cutting, welding and heat-treatment resources. CNC machining can be integrated for designated interfaces, with coordinate measurement and material inspection used to verify the agreed production requirements. The fabrication route is selected to suit the approved liner design.
Please provide engineering drawings or a representative physical sample for quotation and technical review. If drawings are unavailable, OBT can evaluate the sample for reverse engineering. The material, critical dimensions, quantity and inspection requirements are agreed with the customer before production.
