Strong Support for Long Convection Tubes
Intermediate tube sheets are used to support and position long furnace tubes in the convection section. They are important structural parts for stable operation of tube furnaces. An product carries the tube weight. It balances thermal expansion stress. It keeps the tube bundle straight. This stops the tubes from shaking, bending, or moving under high heat and gas flow. So the product directly helps the furnace run safely for a long time. Our product has a maximum hanging length of 35 times the tube outer diameter (up to 6 meters). The support is strong, and the structure is very stable.
High Temperature Alloy Options
We offer several casting materials for our intermediate tube sheet, such as 25Cr-35Ni and 25Cr-20Ni. These alloys resist high heat, creep, and flue gas corrosion. They keep their strength and shape stability for many years in the hot convection section. The holes on the product are made with high precision. The force is spread evenly. The gap between the tube and the sheet is just right. Installation is easy, and the fit is good. We have 26 years of experience in special equipment making. We hold ISO, ASME U&S, and other international certifications. From material buying to casting to machining to testing, we control every step.
We can make the intermediate tube sheet according to your drawings, tube size, and convection section layout. We support OEM and ODM. The minimum order quantity is low. This is very good for overseas agents who need furnace parts or spare supplies. Our products use precision casting and machining. The size is consistent, and parts can be swapped. This meets batch buying and fast replacement needs. Every sheet goes through size checks, mechanical property tests, and non-destructive testing. The quality is stable. Standard products take about 3 months for delivery. Custom products take 4 to 6 months. We deliver on time for overseas projects.
