Abstract
The utility model discloses a steel wire braided net framework reinforced plastic multiple-unit tube, which comprises an internal and external plastic layer, and one layer or a plurality of layers of steel wire braided nets. The steel wire braided net applies single up-and-down braided method or double up-and-down braided method or weft knitting method, which is bonded together with the internal and external plastic layer through binding agent or the plastic directly crossing grids and tightly fixed the braided net in the plastic. The multiple-unit tube has the advantages of high intensity, corrosion prevention, excellent waterpower performance, and wide applicability, which can be used in the fields of the mineral oil, natural gas, municipal works, and industrial fluid transportation or the like.
Description
Technical field
The utility model relates to a kind of steel-plastic composite pipe, especially relates to a kind of plastic composite tube enhanced by framework of wire-cloth from steel wire.
Background technique
Steel-plastic composite pipe has intensity height, corrosion-resistant, advantages such as hydraulic performance good, simple installation, is widely used in fields such as oil, rock gas, municipal engineering, industrial fluids conveying.At present, the main kind of steel wire mesh frame plastic composite tube has the steel wire point to be welded into mesh reinforced plastic composite pipe (CN 1222418A) and steel wire wound web frame plastic composite pipe (CN 1336503A).The steel wire point is welded into the mesh reinforced plastic composite pipe and forms network framework by welding warp and parallel point of contact, with continuous extruding thermoplastic resins compound molding, and structural stability, withstand voltage anticorrosion.But welding procedure complexity, power consumption, easy scaling loss steel wire, the steel wire designability is poor.Steel wire wound web frame plastic composite pipe twines with steel wire left and right sides spiral and forms mesh skeleton, by high-performance adhesive steel-wire carcass and plastic substrate is closely linked together, and has avoided complicated welding procedure, and manufacturing efficiency obviously improves.Yet steel wire wound web skeleton mainly relies on Bond to fix, and the Bond adhesive property is required high.Along with temperature raises, the Bond performance reduces gradually, and the adhesive strength of steel wire and plastics weakens, and steel wire and plastics can not be worked in coordination with carrying, thereby influence the intensity of tubing.CJ/T 189-2004 " steel wire mesh frame plastic (polyethylene) composite pipe " standard code, steel wire mesh frame polyethylene compound pipe maximum operation (service) temperature is 60 ℃.
Summary of the invention
The purpose of this utility model provides a kind of plastic composite tube enhanced by framework of wire-cloth from steel wire, and it is easy to have an intensity height, sound construction, stable performance, production technology.
The technological scheme that its technical problem that solves the utility model adopts is: comprise by outer layer plastic layer, steel wire mesh frame and inner plastic layer and forming.Described steel wire mesh frame is for being woven into steel wire mesh frame, is bonded to one or plastics directly penetrate grid mesh grid is fixed in the plastic layer by Bond and interior outer plastic layer.
Described braided steel wire stratum reticulare number is one or more layers, and multilayer steel wire woven mesh layer is plastic layer at interval.
Described be woven into netting wire skeleton be Dan Shangdan down or two down two or weft knitting is woven into, be intertwined to form steel wire mesh frame along the tubular axis symmetry with network, the steel wire minimum separable is not less than steel wire diameter in the same way.
When described braided steel wire stratum reticulare number is multilayer, adopt identical or different braided steel wire net to combine.
The utility model is compared the beneficial effect that has with background technique: the utility model composite pipe adopts the braided steel wire network framework, forms whole, firm network framework because steel wire fills up to press mutually, is difficult for taking place slippage, stable performance; Internal and external layer adopts thermoplastic, and is corrosion-resistant, hydraulic performance good.Plastic composite tube enhanced by framework of wire-cloth from steel wire intensity height, corrosion-resistant, flexible good can be applicable to fields such as oil, rock gas, municipal engineering, industrial fluids conveying.

Embodiment
Embodiment 1:
Fig. 1 is the utility model embodiment 1 a structural representation.The left side is the sectional view after the moulding among the figure, and the centre is a steel wire 3 under the Dan Shangdan, and the right side is an inner plastic layer 4.The two-way multi-thread steel wire that is coated with Bond adopts that mode is woven into the braided steel wire net under the Dan Shangdan, twines and formerly pushes on the inner plastic layer 4 of cooling forming.Behind coated with adhesive 2 on the braided steel wire stratum reticulare, extrude outer layer plastic layer 1.Bond is bonded to one braided steel wire stratum reticulare and internal and external layer plastic layer, forms intensity height, constitutionally stable composite pipe.
Embodiment 2:
Fig. 5 is the utility model embodiment 2 a structural representation.The left side is the sectional view after the moulding among the figure, and the centre is a steel wire mesh frame 3 under the Dan Shangdan, and the right side is an inner plastic layer 4.Mode is woven into the braided steel wire net under the steel wire employing Dan Shangdan, twine and formerly push on the inner plastic layer 4 of cooling forming, extrude outer layer plastic layer 1 again on the braided steel wire stratum reticulare, outer layer plastic directly penetrates grid, with firm being fixed in the plastic layer of braided steel wire net.
Embodiment 3:
Fig. 6 is the utility model embodiment 3 a structural representation.Be followed successively by under sectional view after two rack moulding, the Dan Shangdan after steel wire mesh frame 3, the single rack moulding steel wire mesh frame 3, inner plastic layer 4 under sectional view, the Dan Shangdan among the figure from left to right.Mode is woven into the braided steel wire net under the steel wire employing Dan Shangdan, twines and formerly pushes on the inner plastic layer 4 of cooling forming.Extrude intermediate plastic layer 7 behind the coated with adhesive 2, in the winding steel wire mesh grid 3 once more of plastic layer surface, mesosphere.Same coated with adhesive 2 is extruded the outer layer plastic layer at last on braided steel wire net 3.Multi-lay winding braided steel wire net can improve tubing intensity greatly, produces the high pressure composite pipe.
