Appl. No.:

9/468017

Inventors:

Fred D. Wilson - Pasadena TX

International Classification:

F16L 5518

US Classification:

138172

Abstract:

A method and apparatus for providing metal or non-metal vessels, including straight and curved pipes and various pipe connections, such as T's, elbows, swages, etc. , and pressure containing vessels such as tanks, with an external composite lining of a webbing of biaxial or triaxial weave preferably composed of fiberglass which is pre-impregnated with a high temperature heat curable polymer composition capable of being heat cured at a temperature range of from about 275. degree. F. to about 375. degree. F. The vessel is prepared for bonding by abrasive cleaning and by solvent cleaning. Metal imperfections are then filled with an epoxy. A small amount a quick setting epoxy is employed to attach one end of the web to the external surface of the vessel in oriented position for wrapping of the web in intimate surface-to-surface contact with the vessel. During wrapping only enough tension is applied to the pre-impregnated webbing to eliminate any wrinkles. The number of layers of the impregnated webbing will be determined by the safe pressure containing capability of the pipe or vessel and its composite lining.

Abstract:

An electrically insulative chemically resistant support pedestal is provided for supporting heavy mechanical objects, such as chlorine cells which are positioned above a support floor. Each support pedestal is defined by a body of epoxy material for chemical resistant and structural support, which defines a central vertical passage intersecting the upper and lower surfaces of the pedestal. Leveling bolts extend from the lower portion of the epoxy body and function both to anchor the body in assembly with the support floor and to level it. The epoxy body is positioned in assembly with the floor and leveled, after which a quantity of uncured epoxy material is caused to fill the central passage of the body and fill the space between the epoxy body and the support floor to thereby establish grouted contact between the pedestal and the support floor. When positive pinned connection is required between the support pedestal and the supported structure, flexible grout, supporting a locator pin, fills the upper portion of the passage thus allowing minor shifting of the locator pin for proper registry with the locator pin opening in the supported structure.
