Abstract
The utility model pertains to the pipe field, relates to a composite pipe that is widely applied in the field such as petroleum, chemical industry, municipal, building, etc. and is applicable to gas and liquid transportation, threading pipe, structural construction, etc. The utility model is characterized in that: a cement concrete enhancement layer (2) is arranged between the inner wall of an outer pipe (1) and the outer wall of an inner pipe (3) and connects the outer pipe (1) and the inner pipe (3) into one body. The cement material reinforcement composite pipe has comparatively high compressive strength, being uneasy to deform and comparatively low cost of raw material for the cement concrete has comparatively high compressive strength and low production cost. Besides, the production of the cement material reinforcement composite pipe is easy to realize industrial production.
Description
Affiliated technical field:
The utility model belongs to the pipe field, relates to a large amount of composite pipes that use in oil, chemical industry, municipal administration, building and other field, is applicable to gas liquid conveying, threading pipeline and structural architecture etc.
Background technique:
Existing composite pipe, its compressive strength depends on the compressive strength that is used for compound pipe; Compound pipe compressive strength is not high when being used for, and perhaps in order to reduce the product cost of raw material, is used for that compound pipe adopts thin wall thickness and when not possessing high compression strength, the composite pipe that is combined into is difficult to have high compression strength.
Summary of the invention:
The utility model provides a kind of cement material to strengthen composite pipe, and when being used for compound pipe self compressive strength when not too high, it still has high compression strength and not yielding; Perhaps when it reaches required compressive strength, can reduce the wall thickness that is used for compound pipe effectively, reduce the cost of raw material.
The technical solution of the utility model:
The utility model is made of outer tube, interior pipe and cement concrete enhancement layer.In interior tube outside, is the cement concrete enhancement layer with outer tube sleeve between outer tube wall and outer wall of inner tube, and the cement concrete enhancement layer links into an integrated entity interior pipe and outer tube.In addition, stiffening rib or reinforcement tube are set in the cement concrete enhancement layer, can increase the tensile strength of composite pipe effectively.
Beneficial effect:
Because cement concrete has high compression strength, fabricating cost is cheap, and cement material strengthens that composite pipe can have high compression strength and not yielding, perhaps can have the lower cost of raw material.In addition, the working process of cement material enhancing composite pipe also is easy to realize industrialized production.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is that cement material strengthens the composite pipe plan view.
Fig. 2 is that the cement material that stiffening rib or reinforcement tube are set in the cement concrete enhancement layer strengthens the composite pipe plan view.
In the drawings, the 1st, outer tube, the 2nd, cement concrete enhancement layer, the 3rd, interior pipe, the 4th, strong muscle or reinforcement tube.
Embodiment:
In Fig. 1, outer tube (1) is enclosed within interior pipe (3) outside, between outer tube (1) inwall and interior pipe (3) outer wall, form the gap of certain size, cement material is made cement slurry with other material mixture ratio after good on request, cement slurry is poured in the gap between inner and outer pipes, treats that cement slurry solidifies the back and just formed cement concrete enhancement layer (2) between outer tube (1) inwall and interior pipe (3) outer wall; Cement concrete enhancement layer (2) links into an integrated entity interior pipe (1) and outer tube (3), becomes cement material and strengthens composite pipe.
In Fig. 2, outer tube (1) is enclosed within interior pipe (3) outside, between outer tube (1) inwall and interior pipe (3) outer wall, form the gap of certain size, stiffening rib or reinforcement tube are arranged in the gap between inner and outer pipes, cement material is made cement slurry with other material mixture ratio after good on request, cement slurry is poured in the gap between inner and outer pipes, treat that cement slurry solidifies the back and just formed cement concrete enhancement layer (2) between outer tube (1) inwall and interior pipe (3) outer wall, be provided with stiffening rib or reinforcement tube (4) in the cement concrete enhancement layer (2); Cement concrete enhancement layer (2) links into an integrated entity interior pipe (1) and outer tube (3), becomes cement material and strengthens composite pipe.
Outer tube is the moulding pipe of processing on demand or buying from market, and material is metal or plastics.
Interior pipe is the moulding pipe of processing on demand or buying from market, and material is metal or plastics.
The transverse shape of inner and outer pipes is complementary, and can be circle, rectangle or other given shape.
Claims (2)
1: a kind of cement material strengthens composite pipe, constitute by outer tube (1), interior pipe (3) and cement concrete enhancement layer (2), it is characterized in that: between outer tube (1) inwall and interior pipe (3) outer wall is cement concrete enhancement layer (2), and cement concrete enhancement layer (2) links into an integrated entity outer tube (1) and interior pipe (3).
2: cement material according to claim 1 strengthens composite pipe, it is characterized in that: be provided with stiffening rib or reinforcement tube (4) in the cement concrete enhancement layer (2).
