Abstract
The utility model relates to a stainless steel composite steel pipe for the delivery of liquid and gas and wire conduction, which is composed of a stainless steel inner pipe and an outer steel pipe. No agglomerant is needed, under the condition of normal temperature and pressure, the stainless steel inner pipe is inlaid and appressed with an inner wall of the outer steel pipe by means of a purelymechanical working method, and the outer steel pipe comprises a galvanized steel pipe. The utility model is characterized in that structure is simple and reasonable, the inner wall is smooth, the utility model has good corrosion resistance, stability, impact resistance and durability and long service life, scale deposit can not be produced, the secondary pollution of water supply procedure can not be caused, etc.
Description
The utility model relates to a kind of stainless steel composite pipe that is used for liquid, gas delivery and electric wire transporting.
At present, traditional water supply line, its deficiency is: easy scaliness, cause the secondary pollution in the water supply process, influence people's quality of life.In addition, sell plastics and the composite pipe thereof that uses in the existing market, owing to heat resistance, stability, durability, poor impact resistance and cost an arm and a leg and fail generally to use.
The purpose of this utility model is exactly that a kind of simple and reasonable, performance good, quality of water supply is high stainless steel composite pipe is provided in order to overcome above-mentioned deficiency.
The utility model is to be made of pipe 1 and outer steel pipe 2 in the stainless steel, and the interior pipe 1 of stainless steel is inlayed and is close in the inwall of outer steel pipe 2.Outer steel pipe 2 comprises the employing Coating Steel Pipe.
Below in conjunction with accompanying drawing the utility model is done progressive description:
Fig. 1 is a cross section structure schematic representation of the present utility model.
Referring to Fig. 1, the utility model is without any need for Bond, under the situation of normal temperature, normal pressure, processing method by pure machinery, pipe 1 in the stainless steel is inlayed and is close in the inwall of outer steel pipe 2, because pipe is to adopt stainless steel material and inner wall smooth in it, thereby when flowing to draining and fire-fighting water, can not produce phenomenons such as corrosion and incrustation scale in the pipe.Because outer tube is to adopt steel pipe (comprising Coating Steel Pipe), therefore, the utility model is that the advantage of traditional Coating Steel Pipe of collection and Stainless Steel Tube is an one, simultaneously, has overcome the insurmountable drawback of plastics and composite pipe thereof again in addition.
The utility model also can be widely used in fields such as other cold and hot liquids (as chemical industry, food, solar energy, medicine etc.), gas delivery and electric wire transporting.
Characteristics of the present utility model are: simple and reasonable, inner wall smooth has good (salt acid soak 30 days is complete for good high temperature resistant property (can≤450 ℃), corrosion resistance Good), stability, shock-resistant property (hydraulic pressure can reach 5MPa) and durability, and do not have Malicious, tasteless, not living bacterium, non-scaling, long service life (can reach 80 years).
Claims (2)
1, a kind of stainless steel composite pipe that is used for liquid, gas delivery and electric wire transporting is characterized in that being made of pipe (1) and outer steel pipe (2) in the stainless steel, and the interior pipe of stainless steel (1) is inlayed and is close in the inwall of outer steel pipe (2).
2, stainless steel composite pipe according to claim 1 is characterized in that outer steel pipe (2) comprises the employing Coating Steel Pipe.
