Abstract
The invention relates to a PE (Polyethylene) composited tube with an occlusion type spiral porous mesh framework, which is mainly used in building and municipal administration water supply main tubes. The PE composited tube comprises a base material (1) and a framework (2), wherein the base material (1) is made of PE. The PE composited tube is characterized in that the framework (2) is made of an occlusion type spiral porous mesh tube. The PE composited tube with the occlusion type spiral porous mesh framework has the characteristics of good toughness, high strength and internal pressure resistance, and the internal framework can not be protruded from the plane at the tube end.
Description
(1) technical field
The present invention relates to a kind of plastic steel composite pipe, be mainly used in building and municipal water supply main pipe.The urgent need bend pipe that also can be used for the heavy caliber rigid pipe in fields such as oil, chemical industry, pharmacy, food, mine, combustion gas.Belong to the composite pipe technical field.
(2) background technique
At present, be applicable to that the building and the plastic steel composite pipe of municipal water supply main pipe have two kinds of steel band skeleton PE composite pipe and steel wire mesh frame PE composite pipes.The former its steel band skeleton of steel band skeleton PE composite pipe is the partition type skeleton, does not have entire body to connect, and poor toughness, intensity are low, and internal pressure-resistant can only not be used for drainage works, is not suitable for water engineering; Though latter's steel wire mesh frame PE composite pipe good toughness, intensity height and internal pressure-resistant, can be used for drainage works, can be used for water engineering again, but because its skeleton steel wire is subjected to extraneous temperature difference influence easily, generation is expanded with heat and contract with cold, and makes the inner skeleton steel wire expose the pipe end plane, and butt joint produces to be squeezed, make the joint produce string water phenomenon, reduce pipe working life.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of good toughness, intensity height, internal pressure-resistant, inner skeleton can not expose the PE (Polyethylene) composited tube with occlusion type spiral porous mesh framework on pipe end plane.
The object of the present invention is achieved like this: a kind of PE (Polyethylene) composited tube with occlusion type spiral porous mesh framework, comprise base material and skeleton, and the base material material adopts PE, and skeleton adopts biting type spiral hole webmaster.
PE (Polyethylene) composited tube with occlusion type spiral porous mesh framework of the present invention also can be set up stiffening rib on described skeleton surface.
The invention has the beneficial effects as follows:
1, adopt the spiral hole webmaster to make skeleton, this skeleton is by band muscle hole pattern band steel spiral interlock moulding, has improved toughness, intensity and the internal pressure-resistant value of pipe greatly.
2, owing to have additional stiffening rib at the spiral hole webmaster, cushioned tube and tube and connected flexible that the back pipe is subjected to that the extraneous temperature difference causes, can not make the inner skeleton expose the pipe end plane, butt joint produces to be squeezed, make the joint produce string water phenomenon, the working life of having improved pipe.
3, owing to the high strength that change brought of skeletal structure, the present invention need not the traditional similar PE tube wall thickness of picture, also can satisfy the intensity internal pressure-resistant that the PE supply pipe should possess.So can save the PE material greatly, reduce product cost.
4, at spiral hole webmaster inner and outer surface coating hot-melt adhesive, make the spiral hole webmaster be difficult for getting rusty, and strengthened the adhesive strength of PE and steel band, improved the working life of pipe.
5, because the high strength that change brought of skeletal structure makes it can apply to the large-caliber water supply pipe, maximum can be to ￠ 1500mm.
6, owing to the change of skeletal structure, joint is handled and can be adopted electro-fusion sleeve or the butt joint of pipe hot melt, adds cast iron anchor ear or electric capacity pyrocondensation again and connects, and is more reliable, safer, reduces the hidden danger of joint explosion greatly.
This pipe can be used for feedwater.Shock resistance under the low temperature, function admirable, the material at low temperature catalytic temperature is low, uses safely in-35 ℃～-60 ℃ temperature range; The surface is unaffected during by the sunlight direct projection; When being subjected to external impact, toughness is better, can recover at once, also can not break under the situation of setting of ground.

(5) embodiment
Referring to Fig. 1, Fig. 1 is the structural representation of PE (Polyethylene) composited tube with occlusion type spiral porous mesh framework of the present invention.As seen from Figure 1, PE (Polyethylene) composited tube with occlusion type spiral porous mesh framework of the present invention, described composite pipe are to be base material 1 with PE, and the spiral hole webmaster is a skeleton 2, and hot melt adhesive 3 is a Bond.
Referring to Fig. 2, Fig. 2 is a skeleton stereogram of the present invention.What as seen from Figure 2, described skeleton 2 adopted is biting type spiral hole webmaster.This biting type spiral hole webmaster is to adopt hole pattern ribbon spiral interlock moulding, and its seaming node as shown in Figure 3.
In addition, the present invention can also save the consumption of PE thus by setting up the intensity that stiffening rib 4 is strengthened composite pipe greatly on skeleton 2 surfaces, uses PE still less to make high-strength big-diameter spiral hole webmaster skeleton PE composite pipe, as shown in Figure 4.
Claims (2)
1. a PE (Polyethylene) composited tube with occlusion type spiral porous mesh framework comprises base material (1) and skeleton (2), and base material (1) material adopts PE, it is characterized in that: described skeleton (2) adopts biting type spiral hole webmaster.
2. a kind of PE (Polyethylene) composited tube with occlusion type spiral porous mesh framework according to claim 1 is characterized in that: have additional stiffening rib (4) on described skeleton (2) surface.
