What holds together the sections of a cast iron sectional boiler?

The sections of a cast iron sectional boiler are held together by tie rods. These tie rods provide the necessary tensile strength to maintain the structural integrity of the boiler by tightly clamping the different cast iron sections together. This ensures that the sections are securely connected, allowing the boiler to efficiently contain the high pressures and temperatures associated with its operation.

Tie rods are essential as they allow for thermal expansion of the boiler sections without compromising the strength or stability of the entire assembly. By securing the sections tightly, they also help prevent leaks where the sections meet, contributing to the overall safety and efficiency of the boiler system.

While steel studs, stay bolts, and cast iron pipes are components associated with different boiler systems or applications, they serve different purposes. Steel studs may be found in other types of constructions or bolted connections, and stay bolts are primarily used in pressure vessels and steam boilers for structural support. Cast iron pipes are components for fluid transport, not for connecting boiler sections.
