Abstract
The utility model relates to a hot winding polyvinyl composite steel-pipe, which is in particular suitable for the anticorrosive pipeline outside of the larger caliber for conveying oil gas. The composite steel-pipe is that a layer hot winding butyl rubber sheeting material is arranged on the outer surface of a metal spiral steel-pipe and adheres to the steel-pipe into the integration; three layers of hot winding polyvinyl sheeting material can be arranged outside of the butyl rubber layer; the overlapping position of each layer of sheet material is not less than 2/3; the hot winding polyvinyl sheeting material adheres to the butyl rubber sheeting material together, forming a clamping casing; the polyvinyl composite steel-pipe is formed. The composite steel-pipe has good anticorrosive property and anti-pressure and does not easily crack.
Description
The utility model relates to a kind of composite steel tube, is particularly suitable for the outer anti-corrosion pipeline of heavy caliber that oil gas is carried.
Pipe-line is outer anticorrosion at present, mainly adopts polyethylene jacket anti-corrosion pipe, because this composite steel tube is polyethylene coating jacket or whole jacket, its shell is aging easily, so normal shelling or the axial cracking of taking place; And because of this cladding jacket of radially extruding axially differs bigger with radial performance, therefore also easily cause radially and ftracture, be not suitable for the outer anticorrosion of large-diameter steel pipe especially.
For overcoming the deficiencies in the prior art, the utility model designs the outer corrosion-resistant heat of a kind of suitable large-diameter steel pipe and twines the polyethylene composite steel tube, not only have corrosion-resistant, and pressure resistance, not easy to crack.
The purpose of this utility model is achieved in that the butyl rubber sheet material that the metallic steel tube-surface has one deck heat to twine, be bonded as one with steel pipe, the polyethylene sheets that outside the butyl glue-line, has three layers of heat to twine, every synusia material lap-joint is no less than 2/3, be bonded together with the butyl rubber sheet material, form jacket, constitute the composite structure steel pipe.
The utility model is compared with existing clad type or whole polyethylene jacket anti-corrosive steel tube, because heat is twined polyethylene composite steel tube shrinkage direction and winding direction basically identical, so be difficult for producing shelling and axial cracking phenomena, twine the polyethylene jacket because of heat in addition, it is axial, radial strength is basic near consistent with specific elongation, all directions are stressed evenly, compare with coating clipping layer, are difficult for causing radially cracking; Particularly this composite steel tube is applicable to the outer anticorrosion of the outer anticorrosion of large-diameter steel pipe and spiral welding bead steel pipe.
Description of drawings is as follows:
Fig. 1 is the polyethylene compound steel pipe structure schematic representation that heat is twined;
Fig. 2 is a polyethylene jacket structural representation.
Among the figure: the 1--Spiral Steel Pipe; 2--butyl rubber sheet material; 3--polyethylene jacket
Below in conjunction with accompanying drawing the utility model is further described: the butyl rubber sheet material that the winding of one deck heat is arranged at the metallic steel tube outer surface of φ 273～720mm at treated caliber, its thickness is 0.5～1mm, with the steel pipe secure bond be one, the polyethylene sheets that has three layers of heat to twine in butyl rubber sheet material outside, every synusia material is 2/3 overlap joint, layer thickness is 1.2 ± 0.2mm, forms the polyethylene jacket, and its jacket thickness is 3.5 ± 0.5mm.
Claims (2)
1, a kind of heat is twined the polyethylene composite steel tube, mainly is made of metal steel pipe and polyethylene clipping layer, it is characterized in that the butyl rubber sheet material that the metallic steel tube outer surface has one deck heat to twine, and is bonded as one with steel pipe; The polyethylene sheets that has three layers of heat to twine outside the butyl rubber sheet material forms the polyethylene clipping layer, is bonded as one with butyl rubber sheet material and steel pipe, constitutes heat and twines the polyethylene composite steel tube.
2, heat according to claim 1 is twined the polyethylene composite steel tube, it is characterized in that every layers of polyethylene sheet material lap-joint is no less than 2/3, and layer thickness is 1.2 ± 0.2mm, and its clipping layer thickness is at 2～4mm.
