Abstract: Mortar-coated steel pipe comprise a steel cylinder having a mortar layer disposed therein, such mortar layer being free of any metallic reinforcement. An overcoat is disposed over the mortar layer and is formed from a material that is a dielectric and/or a barrier to moisture and oxygen entering the mortar layer, e.g., a polymeric material. The pipe may include a further concrete or mortar layer disposed over the overcoat, forming an outermost pipe surface. The outer layer can be cement, mortar, or other material. The mortar layer thickness is about 2 to 30 mm, the overcoat thickness is about 0.1 to 2 mm, and any outer layer thickness is about 1.2 to 4 cm. The pipe is made by compression coating method, where mortar layer and overcoat are applied simultaneously. When an outer layer is desired, it is preferably applied at the same time as the mortar layer and overcoat.

Abstract: Pressure cast lined steel pipes comprise an annular concrete or mortar liner along an inside diameter, and a metal shell surrounding the liner, wherein the liner is in direct contact with the metal shell. The wall thickness of the liner can be from 10 to 50 times the thickness of the metal shell. The pipe may be coated with a dielectric material. A mold assembly used to form the pipe includes an annular concrete or mortar composition chamber formed between the metal shell and an inner mold member. Pressurized water is used in the mold assembly to pressurize the concrete or mortar composition and exert a desired pressure force onto the metal shell while the composition cures in the mold. Once a desired degree of cure is achieved, the pressure is removed causing the metal shell to exert a desired compression force onto the cured liner.

Abstract: Poles of this invention have an annular body with a wall structure comprising a number of fiber reinforced resin layers, which can be positioned to form an inside and/or outside portion of the wall structure. A portion of the layers are oriented longitudinally within the wall structure, and the wall structure also includes radially-oriented fiber reinforced resin layers. The pole includes one or more layers or a core of a composite material or polymer mortar disposed within one or more locations of the wall structure, e.g., as an intermediate layer and/or as part of the wall inside and/or outside portion. The pole can include an outside surface resistant to ultra violet radiation. Poles of this invention can be formed using a continuous process on a rotating mandrel, making use of differently positioned stations to form the different portions of the pole as the fabrication is moved axially along the mandrel.

Abstract: Fire resistant pipes and pipe fittings include a structural pipe wall formed from helically wound reinforcing fiber that is bonded together with a thermoset polymer resin selected from the group consisting of phenolic resins, siloxane-modified phenolic resins, furan resins, and mixtures thereof. In a first embodiment, a resin rich fire resistant layer is applied to the surface of the structural pipe wall. The carrier is capable of accommodating a large amount of resin. The resin used to impregnate the carrier is selected from the same group of resins used to form the structural pipe wall. It is desired that both resins be compatible, and preferably be the same, to facilitate forming a bond between the structural pipe wall and the fire resistant layer during cure. In a second embodiment, a number of energy absorbing material layers are disposed around the structural pipe wall, and are formed from a material capable of absorbing heat energy from a surrounding outside layer to produce a thermally insulating gas therebetween. A number of fiber-reinforced resin layers are disposed around the absorbing material layers. The fire resistant layer and energy absorbing material layers are formed having sufficient wall thickness to protect the structural wall from heat induced failure produced by exposing the outermost pipe wall to a 1,000 .degree. C. flame for at least five minutes in a dry condition.

Abstract: Fiber-reinforced resin pipes and pipe fittings have a structural pipe wall formed from helically wound reinforcing fiber that is bonded together with a polymer resin. An intermediate layer is disposed around the structural pipe wall, and a fiber-reinforced layer is disposed around the intermediate layer. The intermediate layer is formed from material selected from the group consisting of impact attenuating and impact absorbing materials. The fiber-reinforced resin layer comprises layers of helically wound reinforcing fiber bonded together with a polymer resin. The materials selected to form the fiber-reinforced resin layer can be the same or different from that used to form the structural pipe wall. The pipe may comprise a single intermediate and fiber-reinforced layer disposed around the structural pipe wall, or may comprise an impact resistant jacket disposed around the structural pipe wall, wherein the jacket is made up of alternating intermediate and fiber-reinforced resin layers. Fiber-reinforced resin pipes, constructed according to principles of this invention, have improved impact resistance when compared to conventionally constructed fiber-reinforced resin pipes.
