A link-type seismic tie is provided between a steel structural support and a buckstay, and includes two horizontally arranged, parallel, and spaced apart link members, which are connected at their ends to large vertical pins. Each of the link members includes two horizontally arranged and parallel longitudinal outboard stringers and a horizontally arranged and parallel longitudinal center stringer centered between the two outboard stringers. Each link member further includes finger plates standing upright and spaced apart from each other relatively perpendicular to the longitudinal stringers. The finger plates are held between each of the outboard stringers and the longitudinal center stringer. A gusset plate connects the outboard stringers to a pin plate, which is connected to a large pin at the buckstay. The other end of the link members is connected to a large pin at the steel structural support via the ends of the outboard stringers.

A buckstay system for a membraned-tube wall of a steam generator having a first wall section which meets a second wall section at an angle to form a corner. At least one buckstay extends across at least part of each wall section. A pair of tie bars are welded to each other at the corner, an end connection corner tie is welded at the corner to the pair of tie bars, and a pair of end connection buckstay brackets are welded to each end of the buckstays. A pair of pinned end connection links, an end connection corner tie and the end connection buckstay bracket transmit forces from one buckstay to the other wall's tiebar. Bending forces which tend to bend each wall section are transmitted to each respective buckstay which resists such forces. Each buckstay is provided with at least one new anchor assembly having upper and lower support plates welded to the outside surface of the tubes and engaged with each buckstay, two pads welded to and spaced from each other on top of each support plate, and a U-shaped plate welded on top of each pad to form an aperture. A first extended standoff nearest the corner is welded directly to one tie bar and its upper and lower ends are received within apertures formed by the U-shaped plates. A second extended standoff welded to a bumper plate and also to the tie bar moves in the space between the pads. A third extended standoff's upper and lower ends are received within apertures formed by the other U-shaped plates and is engaged to its associated buckstay.

Boiler buckstay system

A support lug casting for supporting a ferritic tube from an adjacent tube comprising male and female lugs formed on a ring shaped member and engaged around but not welded to each tube. The male lug of one tube engages into the female lug of an adjacent tube. The lugs and rings are made of austenitic material which resist corrosion and heat and which avoids the problem of welding dissimilar materials to each other since no welded connection is established between the austenitic casting and the ferritic tube. The casting is axially fixed on the tube by one or more ferritic stops or weld areas which are at one or both axial ends of each casting.
