Latest Patents
Lawrance holds a patent for a "Head closure apparatus for heat exchanger." This invention introduces a novel head closure apparatus specifically designed for shell and tube-type heat exchangers. The apparatus is engineered to be substantially resistant to thermal stress cracking, featuring an internal closure chamber that effectively withstands and dissipates thermal stresses caused by rapidly changing thermal gradients. Additionally, it allows for full access to the entire interior volume of the head closure and the head closure inner tubesheet surface, facilitating maintenance and repairs. The invention also includes a compact and efficient retaining key apparatus that constrains the end-cover of a cylindrically-shaped head closure member against internal working pressures. This design leads to significant reductions in the masses of the retaining keys, head closure member, and end-cover, making the apparatus simpler and more economical to manufacture and maintain.
