Abstract
The invention discloses a method for processing rubber composited steel pipes. The method includes performing fixed-scale cutting on the steel pipes, then performing sand blasting treatment on the steel pipes to derust the steel pipes and welding the derusted steel pipes for standby application; internally mixing and pressing, by weight, 35-45 parts of natural rubber, 50-65 parts of chlorinated rubber, 60-70 parts of carbon black, 8-12 parts of synthetic ferric chloride, 0.5-2.0 parts of rubber aging inhibitors, 0.3-0.7 part of accelerators, 1-3 parts of stearic acid, 3-7 parts of light magnesium oxide and 0.5-1 part of rubber auxiliaries, and squeezing the natural rubber, the chlorinated rubber, the carbon black, the synthetic ferric chloride, the rubber aging inhibitors, the accelerators, the stearic acid, the light magnesium oxide and the rubber auxiliaries to obtain rubber pipes; lining the rubber pipes in the steel pipes by the aid of a traction machine, adhering the rubber pipes with the steel pipes and vulcanizing and shaping the rubber pipes and the steel pipes to obtain the rubber composited steel pipes. The method has the advantages that a process is simple, the rubber composited steel pipes are easy to manufacture, and the manufactured pipes are good in corrosion resistance, excellent in heat-insulation performance, high in strength and low in production cost.
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, can be directed in good rigidly, short distance, can be used for creeping into operation, shortcoming is tortuous winding to carry at a distance.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 for creeping into operation.Therefore, need a kind of new composite pipe.
Summary of the invention
The processing method that the object of this invention is to provide a kind of ultra high molecular polyethylene composite steel tube, technique of the present invention is simple, manufactures easily, and pipeline corrosion resistance, the heat-resisting quantity making, 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: will after Steel pipe fixed length cutting, carry out derusting by sandblasting processing, to standby after the steel-pipe welding after rust cleaning; By natural rubber, chlorinated rubber, carbon black, synthesizing chlorinated iron, rubber antioxidant, promoter, stearic acid, light magnesium oxide and rubber chemicals banburying moulding, by extruder, extrude and obtain rubber pipe simultaneously; Rubber pipe is served as a contrast in steel pipe by tractor, and rubber pipe and steel pipe bonding 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 does not have good plasticity before sulfuration, with steel pipe inner wall close contact, and low to steel pipe requirement, can adopt ratio-frequency welded tube, reduce costs, cylinder iron manage, roll up welded tube and 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 traditional single screw extrusion molding, be improved to the reaction extruding and moulding in extruding and moulding new process, material is constantly accepted between the external heat and screw rod and plastics of barrel, shearing friction heat between barrel and plastics, melting is viscous state then under the effect of extrusion system gradually, plastic melt is by the effigurate extrusion die of tool, thereby obtain the effigurate tubing of tool, compare with original single screw extrusion molding technology, Repeat-heating has been avoided in reaction extruding and moulding, can adjust in time monomer in process of production, the physical property of raw material, guarantee quality of product, reduce production costs.
