Description
Technical field
The present invention relates to a kind of manufacture method of tubing, be specifically related to a kind of processing method of rubber combined steel pipe.
Background technique
Existing steel strength is high, good toughness, shock-resistant, good welding performance, is the conventional pipelines such as conveying granular material, grinding, Korrosionsmedium, but steel pipe hardness low, wear no resistance, corrosion-resistant, working life is short, cost is high.The continuous steel pipe that the seamless steel pipe of Common Straight Carbon Steel adopts mechanical device to connect, its advantage be high pressure resistant, intensity good, good rigidly, can be directed in short distance, can be used for creeping into operation, shortcoming is can not tortuous winding long-distance sand transport.The advantage of rubber pipe be high pressure resistant, be not afraid of bending, long distance without interface; Shortcoming is high-pressure rubber hose, its pipe shaft softness, poor rigidity, does not possess orientating function, can not be used for creeping into operation.Therefore, a kind of new composite pipe is needed.
Summary of the invention
The object of this invention is to provide a kind of processing method of rubber combined steel pipe, present invention process is simple, manufactures easily, and obtained pipeline corrosion resistance, heat-resisting quantity, bending is good, heat insulating ability is excellent, intensity is high, and cost of production is low.
The object of the invention is to be achieved through the following technical solutions, a kind of processing method of rubber combined steel pipe: after being cut by Steel pipe fixed length, carry out derusting by sandblasting process, to for subsequent use after the steel-pipe welding after rust cleaning; Simultaneously by natural rubber, chlorinated rubber, carbon black, synthesizing chlorinated iron, rubber antioxidant, promoter, stearic acid, light magnesium oxide and rubber chemicals banburying moulding, extruded by extruder and obtain rubber pipe; Serve as a contrast in steel pipe by rubber pipe by tractor, rubber pipe and steel pipe bond and sulfidization molding, obtain rubber combined steel pipe.
Preferably, the weight portion of described natural rubber, chlorinated rubber, carbon black, synthesizing chlorinated iron, rubber antioxidant, promoter, stearic acid, light magnesium oxide and rubber chemicals is respectively 35-45,50-65,60-70,8-12,0.5-2.0,0.3-0.7,1-3,3-7,0.5-1.
Preferably, the weight portion of described natural rubber, chlorinated rubber, carbon black, synthesizing chlorinated iron, rubber antioxidant, promoter, stearic acid, light magnesium oxide and rubber chemicals is respectively 40,60,60,10,1,0.5,2,5,0.8.
Compared with prior art, the present invention has following beneficial effect: first, rubber pipe has good plasticity before unvulcanized, with steel pipe inner wall close contact, and require low to steel pipe, can ratio-frequency welded tube be adopted, reduce costs, cylinder iron manage, roll up welded tube and then can manufacture heavy caliber pipe, and silicone rubber, fluorine rubber have high temperature resistant, high pressure, resistance to bending, the advantage that corrosion resistance is strong.Second, by the shaping reactive extrusion molding be improved in extruding and moulding new process of traditional Single screw extrusion, material constantly accepts between the external heat of barrel and screw rod and plastics, shearing friction heat between barrel and plastics, melting is that viscous state is then under the effect of extrusion system gradually, plastic melt is by the effigurate extrusion die of tool, thus obtain the effigurate tubing of tool, compared with original Single screw extrusion forming technique, reactive extrusion molding avoids Repeat-heating, monomer can be adjusted in time in process of production, the physical property of raw material, ensure quality of product, reduce cost of production.
