Corrugated Furnace Machine: Add Strength and Efficiency to Cylindrical Boiler Parts with Shaped Rollers

Inside many boilers, the hottest and most stressed part is the furnace, the cylindrical chamber where the flame burns and the surrounding water takes up the heat. A corrugated furnace is shaped with waves along its length, and those waves change everything. The SBFM Corrugated Furnace Machine (OD) gives form to cylindrical bent parts by rotating them and applying pressure between rollers, adding strength to the part while helping the finished boiler work more effectively.

Quick Product Facts

• Capacity basis: Steel with a yield limit of 24 kg/mm² (about 235 N/mm²)

What Is a Corrugated Furnace Machine?

A corrugated furnace machine turns a plain cylinder into a furnace tube with a wave-shaped profile. The cylinder is first rolled and welded from plate. It is then rotated between rollers whose shape matches the wave, and pressure from the rollers presses the corrugations into the wall, a little at a time, as the part turns.

The result is a cylindrical part with a rippled outer surface that is far stiffer than a smooth tube of the same wall thickness. It is this stiffness, together with the larger surface area, that makes corrugated furnaces so valuable in boiler construction.

Why Corrugation Makes Better Furnaces

The waves work like built-in stiffening rings. They help the furnace resist the pressure of the water that surrounds it, so the wall can be thinner and lighter than a plain tube while still staying safe. They also give the furnace room to flex when temperatures rise and fall during operation, which reduces stress at the welds and joints. In addition, the larger surface area and the turbulence created by the waves improve contact between the hot gases and the wall, which supports better heat transfer. The machine is also described as providing more effective heating by changing the heating method, reducing costs while increasing efficiency, and as being friendly to the user and the environment.

Key Features and Benefits

• Rotating and pressing action that forms corrugations gradually and evenly
• Shaped roller set matched to the wave profile you need
• Added strength for cylindrical bent parts
• Capacity rated for 24 kg/mm² steel so planning is clear and consistent
• More effective heating method that lowers costs and raises efficiency
• User and environment friendly design for safe, cleaner production
• Rigid machine body with a safety guard around the working area

Materials You Can Form

Sheet bending capacity is given for steel with a yield limit of 24 kg/mm². Parts made from harder materials or higher yield limits need more force and may reduce the thickness or size you can corrugate. Always confirm capacity for your own material, wall thickness and cylinder diameter before ordering.

Applications

• Furnace tubes for fire-tube boilers
• Steam and hot water boilers
• Industrial heating and process equipment
• Heat exchangers and combustion chambers
• Flexible, stiffened cylindrical shells
• Marine and land-based boiler manufacturing

Tips for Perfect Corrugations

Start with a well-rolled, round and cleanly welded cylinder, because corrugating cannot correct a poor shape. Keep the surface free of scale and weld spatter to protect the rollers. Form the waves gradually over several turns instead of one deep pass, and check the pitch and depth against a template.
