Embodiment Construction

[0034] figure 1 Shown is an embodiment of a pipe segment or part of a pipe section 10 in which the rubber and reinforcing material are included in separate layers, the pipe section 10 thus comprising a material compatible with the liquid transported in the pipe The inner rubber layer 11. The inner rubber layer 11 is surrounded by a first reinforcing layer 12, in the illustrated case: a woven wire mesh, the wires on which have a winding angle of about 54° in both wire directions. The first reinforcing layer 12 is surrounded by an intermediate rubber layer 13 whose thickness is generally greater than that of the inner rubber layer 11 . The middle rubber layer 13 is surrounded by a second reinforcement layer 14 . Although in the case of the illustrated embodiment the second reinforcement layer is identical to the first reinforcement layer 12, it could also be different from the first reinforcement layer and still be within the contemplation of the present invention, and the sec...

Abstract

A corrosion-resistant and fire-resistant pipe system suitable for sprinkler systems and the like in the offshore industry and also on military and civilian seagoing vessels, and generally as sprinkler systems in official buildings and in industrial buildings. The pipe system is characterized in that the pipe system includes rigid and cold-formable pipe sections (10) that have one or more tubular rubber layers (11, 13, 15) and reinforcement layers (12, 14) that surround or embrace one or more of the tubular rubber layers (11, 13, 15). The reinforcement layers are comprised of wires or ribbons that have been wound, braided, knitted or formed in some other way so as to cross each other, wherein each of the wires or ribbons defines with the longitudinal axis of the pipe section a winding or spiraling angle that imparts the greatest possible strength to the reinforced, tubular rubber layers (11, 13, 15). In the present case, the system also includes branch connections (18) for connecting a pipe section (10) to another pipe section in a multi-path coupling.

Description

technical field [0001] The invention relates to a corrosion-resistant and fire-resistant piping system, which is suitable for sprinkler fire extinguishing systems in marine industries, military and civilian marine ships, and sprinkler fire extinguishing systems in public buildings and industrial buildings. Background technique [0002] Traditional steel pipe systems are not suitable for transporting corrosive liquids such as sea water and industrial waste liquids and other similar waste liquids. In the offshore industry, for example where seawater pipes for cooling and fire-fighting purposes (sprinkler systems) are highly required, attempts have long been made to replace traditional steel materials by other, hopefully more suitable, materials. In this regard, a great deal of work has been done. In order to switch to more expensive metal materials, such as steel materials with higher alloy content, such as SMO steel, which is an acid-resistant chromium-nickel alloy steel con...
