Recently, CCEWOOL® shipped seven pallets of ceramic fiber blankets to a customer in Pennsylvania, USA. The shipment included two sizes, 1″ × 24″ × 300″ and 2″ × 24″ × 150″, for replacing the backup insulation in the radiant-section walls and roof of a petrochemical hydrogenation furnace. Upon arrival, the blankets will be prepared for cutting and installation according to the actual furnace dimensions.

Radiant-Section Wall and Roof Backup Insulation: Ceramic Fiber Blankets Provide Continuous Thermal Insulation

The walls and roof of a petrochemical hydrogenation furnace's radiant section are continuously exposed to high-temperature flue gases and radiant heat. The furnace lining must not only meet the temperature requirements of the hot-face working layer but also limit heat transfer to the furnace shell. In lining systems that use refractory materials or ceramic fiber modules as the hot-face layer, ceramic fiber blankets are installed behind them as backup insulation. The blankets provide additional thermal resistance, while their flexible structure allows them to conform to furnace walls, roofs, and local structural details.

The CCEWOOL® Refractory Ceramic Fiber Blanket supplied for this project has a classification temperature of 2300°F and a specified operating temperature of 2012°F. Its intended application is backup insulation for the radiant-section walls and roof, rather than a direct replacement for the refractory working lining or an unprotected hot-face material. Material selection must be based on the long-term interface temperature at the blanket layer, considering the hot-face lining thickness, overall lining configuration, temperature fluctuations, and design safety margins.

Two Thickness Options and On-Site Cutting: Matching Supply Dimensions to Backup Insulation Requirements

This shipment includes 1-inch and 2-inch blanket thicknesses to accommodate different insulation space requirements in the furnace walls and roof. The customer can arrange cutting according to the existing lining configuration, actual dimensions after removal of the old insulation, and required backup insulation thickness. In addition to thickness, the installation plan should account for blanket width, cutting length, number of layers, corner overlaps, and staggered joint arrangements.

Before replacing the backup insulation, the condition of the furnace shell, retained hot-face lining, anchors, and available installation space should be inspected after removal of the existing lining. Cutting dimensions should then be determined based on equipment drawings and on-site measurements. For multilayer installation, staggered joints and perimeter closures should be incorporated into the layout to avoid continuous through-joints. Where compression is required, cutting dimensions must reflect the specified installation compression, rather than treating the nominal thickness of an uncompressed blanket as its installed thickness.

U.S. Warehouse Supply: Local Support for Maintenance Materials and Future Procurement

This shipment was dispatched through the CCEWOOL® U.S. warehouse distribution network. Warehouse products are manufactured within CCEWOOL®'s own production system under consistent product standards and quality control, following a manufacturer-direct supply model. For North American industrial customers, combining manufacturing capabilities with local warehousing makes it easier to coordinate product grades, inventory quantities, and delivery schedules.

CCEWOOL® operates U.S. warehouses in Charlotte, North Carolina, and Youngstown, Ohio, allowing shipments to be coordinated according to project location, available inventory, and delivery requirements. The warehouse product range includes ceramic fiber blankets, boards, modules, papers, bulk fibers, ropes, soluble fibers, polycrystalline wool, insulating firebricks, and related insulation products. This supports regular replenishment and multi-product procurement. Customers with recurring purchasing needs or annual maintenance schedules can also discuss advance stock planning and staged collection based on estimated consumption and project milestones.

In addition to local supply, CCEWOOL® can assist customers in evaluating material grades, thicknesses, densities, and product combinations based on furnace type, installation location, operating temperature, and engineering drawings. The primary focus of this seven-pallet Refractory Ceramic Fiber Blanket shipment is to provide the required specifications for replacing the radiant-section wall and roof backup insulation. Meanwhile, the dual-warehouse network and broad product inventory offer additional support for future maintenance and replenishment needs. Specific quantities and delivery schedules are subject to confirmed inventory availability and logistics arrangements at the time of order confirmation.
