Abstract
The invention relates to an anti-collision stainless steel composite pipe which is provided with a reinforcing bar, comprises a stainless steel composite pipe body and an anti-collision part, and is characterized in that: the stainless steel composite pipe body is composited from ductile cast iron and stainless steel through a centrifugal casting method; both ends of the stainless steel composite pipe body are provided with flanges; and the anti-collision part comprises the reinforcing bar which is arranged on the outer wall of the stainless steel composite pipe body and a round of reinforced steel bars with both ends being fixed on the flanges which are uniformly distributed outside the stainless steel composite pipe body. The anti-collision stainless steel composite pipe overcomes the defects of an existing water supply pipeline, and has the characteristics of anti-corrosion, no easiness in breakage, no chemical reaction, no rust, no scale, long service life, low cost and the like.
Description
One, technical field
The present invention relates to a kind of composite pipe, especially a kind of anti-collision stainless steel composite pipe.
Two, background technique
As water pipe, use after several years, produce a large amount of rust deposites in the pipe, the yellow water of outflow not only pollutes sanitary equipment, and is being mingled with the bacterium that rough inwall grows, and corrosion causes in the water content of beary metal too high, the health of serious harm human body.In the past, the pipeline that is used to supply water mainly is a cast iron tube.The outdoor main sand mo(u)ld cast iron tube of using, indoor is zinc-plated cast iron tube.But be easy to generate a large amount of rust deposites afterwards in several years owing to use, breed bacteria, the health of serious harm human body, we often have such experience, several days no ones of family, the tap of fetching boiling water, this is the best illustration of tubing polluted water to flow out yellow rust.Healthy water use, from pipe, a kind of health, safe, durable water pipe are modern people's needs.
Advantages such as that copper pipe has is corrosion-resistant, the bacterium that disappears be the prime quality in the water pipe, but a shortcoming of copper pipe are that heat conduction is fast, and another shortcoming is exactly that price is expensive; And traditional galvanized pipe easily gets rusty, perishable, easy fouling, grows microorganism easily, produces secondary pollution, threatens health; The composition of plastic tube has the chemical additives phthalein, and is very big to kidney in the human body, liver, testis influence, can cause cancer, kidney to damage, and destroys bodily fuctions's manufacturing system again, and influence is grown, and plastic tube easily breaks.To this, people need a kind of health, safe, durable water supply line to substitute them.
Three, summary of the invention
The objective of the invention is to solve the deficiency of above-mentioned existing water supply line, a kind of anti-collision stainless steel composite pipe be provided, make its have corrosion-resistant, be difficult for breaking, characteristics such as no chemical reaction, non-corrosive, non-scaling, long service life and cost are low.
The objective of the invention is to adopt following scheme to realize: a kind of anti-collision stainless steel composite pipe, it comprises stainless steel composite pipe body and anti-collision parts, be characterized in: described stainless steel composite pipe body is composited with centrifugal casting process by spheroidal graphite cast iron and stainless steel, at stainless steel composite pipe body two ends flange plate is housed all; Described anti-collision parts are included in the stiffening rib on the external wall of stainless steel composite pipe and are fixed on reinforcing bar on the flange disc at the equally distributed circle two ends of external of stainless steel composite pipe.
Above-mentioned stainless steel composite pipe body is by spheroidal graphite cast iron and stainless steel is compound forms, promptly earlier be cast as body with ductile cast iron material with centrifugally cast method, when casting temperature arrives 1400 ℃-1800 ℃, also cast the last layer stainless steel again with centrifugally cast method at inboard wall of tube body.
Above-mentioned stiffening rib is vertical bar shaped stiffening rib or spirality stiffening rib, and it is on the outer wall of Stainless Steel Tube, and it can reduce the Stainless Steel Tube gross weight, strengthens the Stainless Steel Tube structural strength, keeps the Stainless Steel Tube rigidity.
Above-mentioned flange plate also plays fixedly action of steel bars except that the connection that is used between the Stainless Steel Tube.
The two ends of above-mentioned reinforcing bar can directly be welded on the flange disc and also can be fixed on the flange plate with screw.Be contained in the external circle reinforcing bar of stainless steel composite pipe the encirclement of stainless steel composite pipe body is protected, can prevent effectively that Stainless Steel Tube from being broken.Need prevent heat dissipation when stainless steel composite pipe uses in the heating place, adorn foam this moment between reinforcing bar and stainless steel composite pipe body, constitute foam heat-insulation layer, and foam heat-insulation layer can not only be incubated the effect that can also play second protective layer.
The present invention adopts the beneficial effect of such scheme to be: the 1) use of stiffening rib and reinforcing bar has guaranteed the safety of Stainless Steel Tube can prevent effectively that Stainless Steel Tube from being broken; 2) Stainless Steel Tube has advantages such as acid-alkali-corrosive-resisting, weathering resistance, anti-sweep of gases, anti-ash cutting, anti-floating rust, and it is simple to operate, automaticity is high, equipment is simple; 3) stainless steel composite pipe that is formed with spun casting by spheroidal graphite cast iron and stainless steel has stainless characteristics; 4) inner-walls of duct of stainless steel composite pipe is smooth, so do not deposit paraffin, polymer and other sediments basically, guarantees not pollute the product that is transferred simultaneously.In addition, because internal face is smooth, friction factor is little, so under the transmitting power effect that equates, strengthened the passing capacity of pipeline widely, has reduced the conveying cost.
