摘要： In a joint structure, a tube member having a polygonal cross-section can be joined to a flange surface by full penetration welding with good strength margin, without imparting unreasonable force to the weld portion. The joint structure comprises a polygonal cylindrical lower guide tube joined by butt welding to a surface of a middle flange having a through-hole of the same shape as the lower guide tube, wherein at the end of the lower guide tube, within the linear portions that constitute each of the sides of the lower guide tube, there exists a weld portion welded to the surface in at least one location and an unwelded portion located separately from the weld portion, and a level difference at least as large as a distance equivalent to the weld shrinkage of the weld portion is provided between the end positions of the weld portion of the unwelded portion.

摘要： The invention relates to means and methods for rendering fire-safe, or more fire-safe, steel or like pipework which is lined with a plastic or like liner. At joints in such pipework, the liner is brought out over the flange face to form the actual seal. Consequently, the liner is vunerable to fire or other forms of external heat at the joints.In accordance with the present invention, a metal ring is provided around the periphery of the liner at each joint to protect the liner from fire. The metal ring is not intended to provide a complete seal if the seal between the liners should fail, but it does prevent any large escape of the contents of the pipework.The ring may take various forms and may be, for example, a resilient ring of either U-section or M-section. Alternatively, the ring may be of flat-section and may slide on lips formed on inserts arranged between the flanges and the liners. These inserts may be arranged to provide the additional advantage of removing the need for special flange welding and machining.

摘要： A cooling tube includes a tube member extending from a first end to a second end through an intermediate portion having an outer surface and an inner surface. The outer surface has an outside diameter. A flange is mounted at one of the first and second ends of the tube member. The flange includes a flange body extending from a first end portion to a second end portion through an intermediate section having an outer surface and an inner surface. The inner surface defines an inside diameter. The outside diameter of the tube member is between about 0.010-inch (0.0254-cm) and about 0.030-inch (0.0762-cm) smaller than the inside diameter of the flange.
