Abstract
The utility model relates to a composite steel pipe with a high-intensity hollow helical stirrup structure. A polyethylene anti-corrosion layer is formed on the outer wall of a steel pipe body, and aresin adhesive bonding layer is coated between the polyethylene anti-corrosion layer and the outer wall of the steel pipe body. The utility model adopts the innovation point that tubular hollow polyethylene helical stirrups are wound at the outer part of the polyethylene anti-corrosion layer. The utility model with scientific and reasonable structural design integrates the high intensity and highelasticity modulus of steel materials with the advantages of light weight, small resistance factor, corrosion resistance, strong conveyance power of water, good sealing performance, long service life,convenient transportation and installation as well as fast construction of polyethylene, thereby having the remarkable advantages of high ring stiffness, material conservation, easy installation, moderate cost, etc.
Description
Technical field
The utility model belongs to the composite steel tube field, particularly a kind of high strength hollow spiral ribbed steel wire structure composite steel tube.
Background technique
For a long time, the water supply in city and gas transmission pipeline net work adopt the tubing of steel pipe as fed sheet of a media mostly, but traditional steel pipe is an individual layer steel tubular goods structure, and there are many drawbacks in it in engineering is used, be mainly reflected in that intensity is low, wall is coarse, perishable, working life is short etc.Therefore, for overcoming the existing deficiency of above-mentioned monolayer steel pipe, improved steel pipe all adopts the composite steel tube that is shaped on the plastics anticorrosive coat, it has advantages such as intensity height, wall be smooth, corrosion-resistant, therefore on engineering, use comparatively general, but there is the deficiency that pipe thickness is big, pipe is great in this kind structure composite steel tube, causes composite steel tube to occur destabilization problems easily, increases difficulty of construction.In existing high-density polyethylene plastics tubing manufacture field, the hot Wrapping formed mode of existing employing is made polyethylene evagination spiral at the tube wall outer circumferential face and is strengthened rib, improve the tubing ring stiffness thus, solve destabilization problems, but the made polyethylene evagination of its tube wall of above-mentioned plastic tube spiral is strengthened rib and is solid rib, if be used for the steel pipe field then can further increase steel pipe pipe thickness and Guan Chong, thereby increase construction cost and difficulty, therefore be unsuitable for being applied to the steel pipe field, also exist the polyethylene consumption big simultaneously, the high deficiency of cost of production is unfavorable for the raising of economic benefit of enterprises.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and twine the high strength hollow spiral ribbed steel wire structure composite steel tube be shaped on the hollow structure spiral ribbed steel wire at outer wall of steel pipe, its have intensity height, wall thickness little, in light weight, be convenient to outstanding advantages such as construction, cost be low.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of high strength hollow spiral ribbed steel wire structure composite steel tube, be shaped on polyethylene anticorrosive coating at steel pipe body outer wall, between polyethylene anticorrosive coating and steel pipe body outer wall, scribble the resin glue adhesive layer, it is characterized in that: be wound with cannulated structure polyethylene helical rib in the polyethylene anticorrosive coating outside.
And, evenly be coated with the internal plastic coating layer in the steel pipe inner body wall.
And the sectional shape of described cannulated structure polyethylene helical rib is circular pipe, square tubular, laddertron, triangle tube.
Advantage of the present utility model and good effect are:
1. this high strength hollow spiral ribbed steel wire structure composite steel tube adopts and has the stiffening rib of the spiral ribbed steel wire of cannulated structure as composite steel tube, adopt solid spiral ribbed steel wire, it is about 30% to reduce thickness of steel pipe, and it is about 20% to alleviate steel pipe weight, significantly reduces construction labor intensity thus.
2. this high strength hollow spiral ribbed steel wire structure composite steel tube is because employing has the stiffening rib of the spiral ribbed steel wire of cannulated structure as composite steel tube, on the basis of satisfying the required minimum wall thickness (MINI W.) of fed sheet of a media pressure, guarantee the tubing ring stiffness, thereby avoid tubing unstability to occur, simultaneously have root resistance effect again, solved pipeline vertical shift problem.
3. the utility model scientific structure design is reasonable, advantage separately such as high strength, high elastic modulus and the polyethylene of steel is in light weight, that resistance coefficient is little, corrosion-resistant, conveyance power of water strong, good seal performance, long service life, easy transportation and installation and speed of application are fast integrates, have outstanding advantages such as ring stiffness height, material saving, easily installation, moderate cost, also have green clean simultaneously, advantages such as the maintenance source quality is not contaminated help improving drinking water quality and people ' s health level.

Embodiment
The utility model is described in further detail by specific embodiment below in conjunction with accompanying drawing.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of high strength hollow spiral ribbed steel wire structure composite steel tube, be shaped on polyethylene anticorrosive coating 2 at steel pipe body 4 outer walls, between polyethylene anticorrosive coating and steel pipe body outer wall, scribble resin glue adhesive layer 3, its innovative point is: be wound with cannulated structure polyethylene helical rib 1 in the polyethylene anticorrosive coating outside, the sectional shape of this spiral ribbed steel wire is circular pipe, square tubular, laddertron, triangle tube, as shown in Fig. 1-4, can certainly be the cannulated structure of other arbitrary shape.Be shaped on internal plastic coating layer 5 in the steel pipe inner body wall, this internal plastic coating layer is a polyurea layer, can improve the degree of finish of steel pipe inner body wall, has anti-corrosion function simultaneously.
Add man-hour at this composite steel tube, at first the steel pipe body is carried out sand blast; Adopt the hot Wrapping formed production technology of polyethylene then, will from flat strip that the extruder mouth is extruded and cannulated strip by the precalculated position side by side uniform winding scribbling on the steel pipe body outer wall of resin glue, carry out the resin glue coating simultaneously in winding, polyethylene anticorrosive coating and the hot once-through of cannulated structure polyethylene helical rib thus, have higher welded seam quality, and by resin glue adhesive layer and steel pipe body outer wall secure bond.The pitch of spiral ribbed steel wire pipe can be adjusted according to different requirement of engineering.After polyethylene anticorrosive coating and spiral ribbed steel wire twine and finish, carry out the internal layer spraying and mould, make the internal plastic coating layer.
