Abstract
The composite fire-extinguishing water pipe is one carbon steel pipe with a red anticorrosive layer special for fire-extinguishing facility painted to outer surface and a stainless steel lining layer. The composite fire-extinguishing water pipe has clear mark, light weight and no rust in its inner wall, and its use can reduce building load and engineering cost. When the pipe in made in other outer color, the pipe may be used in water supply, gas supply, petroleum industry, chemical industry and other engineering.
Description
One, technical field
The present invention relates to a kind of composite fire-extinguishing water pipe.Be suitable for using on the feedwater piping engineering of structural fire protection system, also be fit to use on the drinking-water pipe engineering.
Two, background technique
At present, also do not have pipe special, generally be to use Coating Steel Pipe to make fire-prevention pipe at the feedwater piping of structural fire protection system.The shortcoming of using Coating Steel Pipe to make a maximum of fire-prevention pipe existence is the easy corrosion of Coating Steel Pipe inwall, and when fire alarm took place, the iron rust in the pipe can stop up the shower nozzle in the fire-fighting system, makes it lose fire-extinguishing function concurrently.Secondly the connection of Coating Steel Pipe is owing to need machining screw, so wall thickness is thick partially, from heavy, make troubles and increases built-loading to construction.
Three, summary of the invention
The present invention provides and a kind ofly can overcome above-mentioned shortcoming, can solve the shortcoming of stopping up shower nozzle because of the pipe inner wall corrosion, and meets need not again that fire codes requires and be threaded, from the composite fire-extinguishing water pipe of heavy and light.
Composite fire-extinguishing water pipe of the present invention comprises carbon steel tube, it is characterized in that the outer wall of carbon steel tube scribbles the anticorrosive coat of the special-purpose look of one deck fire-fighting, and inwall is lined with one deck stainless steel lining, and the three fits tightly.
The color of carbon steel tube outer wall anticorrosive coat is red or other colors of the purposes different choice of root a tree name water pipe, and the special-purpose water pipe of fire-fighting uses red anticorrosive coat to do anticorrosion and graphical symbol.
For making the water pipe antiseptic effect better, can plate corrosion resistant metal layers such as one deck chromium or nickel earlier at the carbon steel tube outer wall, be coated with coloured anticorrosive coat again.
The wall thickness of carbon steel tube is to determine according to caliber size and voltage withstand class, caliber is big, and thickness of pipe wall increases relatively, and caliber is little, thickness of pipe wall reduces relatively, and the wall thickness of stainless steel inner lining layer is to determine according to the minimum thickness that the moulding process of stainless steel inner lining layer and equipment can reach.As make the composite fire-extinguishing water pipe of external diameter Φ 20mm voltage withstand class 1.0Mpa specification, and its carbon steel tube wall thickness is got 1.5mm, and stainless steel inner lining layer wall thickness got 0.2mm.
Composite fire-extinguishing water pipe of the present invention is to utilize thin stainless steel lining to make liner, and carbon steel tube and water are isolated, and avoids inner tube layer to generate solid-state overburden because of the water contacting corrosion, stops up fire-fighting system, guarantees that the shower nozzle in the fire-fighting system can proper functioning.Utilize red coating to make the outer field anti-corrosion protection of carbon steel tube, reached and both risen anticorrosionly, can be used as the graphical symbol of fire-prevention pipe again water pipe.Because adopt non-threaded connecting means such as socket joint pressing connection, water pipe and wall thickness only need be considered compressive strength, and need not to consider to want machining screw and the technology thickness that increases.So tube wall is thinner relatively, can reduce the deadweight and the Master Cost of water pipe, the load minimizing of building structure and the labor intensity of installing are reduced, work efficiency improves, and reaches to save the engineering cost purpose.
The present invention has the following advantages: 1, anticorrosive: the non-corroding thing pollutes the water quality be transferred, prevents the fire-fighting water pipeline phenomenon that is blocked.2, graphical symbol is clear: the pipe outer wall is that fire-fighting is special red, need not the mark lacquer during use again, and it is clear, easy to use to indicate.3, in light weight, easy construction: tube wall is thin, need not to be threaded, and can alleviate load of buildings and construction intensity.4, fireproof performance is excellent: use the noncombustible material manufacturing, can use safely in raging fire.Be applicable on the structural fire protection water supply line engineering and use, also can be used for using on drinking water pipeline and the gas transmission pipeline engineering.
Four, description of drawings
Accompanying drawing 1 is a composite fire-extinguishing water pipe structural representation of the present invention.
Accompanying drawing 2 is composite fire-extinguishing water pipe structural representations that the coat of metal is arranged of the present invention.
1 is red anticorrosive coat among the figure, the 2nd, and carbon steel tube, the 3rd, stainless steel inner lining layer, the 4th, the coat of metal.
Five, specific implementation method
Embodiment 1
Referring to accompanying drawing, with the composite fire-extinguishing water pipe of making external diameter Φ 20mm voltage withstand class 1.0Mpa specification is example, make raw material with carbon steel and stainless steel, make the carbon steel tube 2 and the tubulose stainless steel inner lining layer 3 of cut lengths respectively with steel tube shaping machine, both have the structure of seam or seamless structure, but the inside and outside wall of pipe is smooth, carbon steel tube 2 wall thickness are got 1.5mm, stainless steel inner lining layer 3 wall thickness are got 0.2mm, the external diameter of stainless steel inner lining layer 3 is slightly littler than the internal diameter of carbon steel tube 2, gets final product slidably to be inserted in the carbon steel tube 2.Stainless steel inner lining layer 3 is inserted within the carbon steel tube, and two ends flush, with the draw footpath machine caliber of carbon steel tube 2 is contracted to its inwall and presses on Stainless Steel Tube 3, both are firmly fitted tightly together.With compound pipe two ends finishing, after outer wall carries out oil removing, rust cleaning and passivation with chemical method or physical method, organic coatings such as colored red epoxide powder coating or red acrylic acid, make red anticorrosive coat, coating thickness 30 μ m, also can be behind degreasing and rust removal corrosion resistant metal such as chromium plating or nickel layer, the organic red anticorrosive coats 1 such as epoxy powder of coating Red again, antiseptic effect is better.Promptly make composite fire-extinguishing water pipe of the present invention.
Embodiment 2
Referring to accompanying drawing, the warp on the composite pipe production line with carbon steel band and Stainless Steel Band: tubulose stainless steel inner lining layer 3 moulding, at stainless steel inner lining layer 3 outsourcing carbon restoration steel band and be welded into carbon steel tube 2, compound refining moulding, realize the manufacturing of composite fire-extinguishing water pipe with the pretreatment of composite pipe outer wall, with operations such as the red anticorrosive coat 1 of hot coating thermoplastic plastics, scale cut.The thermoplastic of heat coating usefulness can be selected red polyethylene or red nylon, thick coating 0.1mm for use.Also can cut by scale after the compound pipe molding operation, the method for making red anticorrosive coat 1 with embodiment one is made again, can make composite fire-extinguishing water pipe of the present invention.
