Abstract
The method for making metal composite pipes, including two-component external composite special pipe made of carbon steel pipe, thin wall stainelss steel pipe and non-ferrous metal pipoe, two-component internal composite special pipe and three-component internal-external composite special pipe is characterized by adopting hydraulic balloning combination method and implemented said method in hydraulic balloning combination high-pressure sealing equipment.
Description
Technical field the present invention relates in a kind of stainless steel tube that adopts carbon steel tubing and wall as thin as a wafer and the outer compound circular tube shape tube of the binary that nonferrous metal tube is made, the binary manufacture method of the metal composite pipe of compound circular tube shape tube inside and outside the compound circular tube shape tube and ternary.
Background technology is present, what both at home and abroad the method for the long-term anti-corrosion treatment of metal pipe material surface air surrounding medium is adopted usually is that metal material is carried out surface treatment, as: paint spray dress, plastic-blasting, spray zinc, aluminium-plated, aluminium-plated magnesium alloy, spray allumen etc., these methods can't reach long-term anticorrosion protection.The metal surface anticorrosive treatment technology receives concern both domestic and external in recent years, the domestic technology such as adopting galvanizing, hot-dip aluminizing and hot-dip aluminizing that develops into, these methods only are limited in the surface treatment of micro metal member, and the fluid delivery pipeline adopts methods such as PVC is compound, epoxy resin, cement mortar.External situation is roughly the same, but has adopted Dacromet Technology (DACROMAT) to make the surface anticorrosion etching technique of large-scale metal tube reach a new height in recent years.The decorative engineering pipe of domestic application is 304 stainless steel tubes, makes the tube wall attenuation in use for reducing cost, when being subjected to clashing into, can occur the distortion of structural instabilities such as concavo-convex hole, fracture, bending, not attractive in appearance, not firm, cost is high.And fluid-transporting tubing requires anticorrosive, compression resistance, and thick to the tube wall requirement, cost is then higher.
Summary of the invention the objective of the invention is to be purposes such as decoration device, fluid conveying, heat abstractor, and a kind of employing manufacture method of the metal composite pipe of compound circular tube shape tube and the inside and outside compound circular tube shape tube of ternary in the outer compound circular tube shape tube of binary made of wall stainless steel tube and carbon steel tubing and nonferrous metal tube, the binary as thin as a wafer is provided.
The manufacture method content Description of metal composite pipe of the present invention:
The manufacture method of metal composite pipe of the present invention is characterized in that: adopt waterpower blow-up composite algorithm, carry out on waterpower blow-up composite high pressure sealing device, the concrete practice is:
1, at first will be polished or blasting treatment by the composite surface of compound metal body, again it is set with each other, be placed on the waterpower blow-up composite high pressure sealing device, the two ends, the left and right sides of sealing device are the dense block locking structures, left end is the fixing locking mechanism of adjusting, and right-hand member is a car body operation locking mechanism;
2, will be inserted in the sealing ring of left end by the endoporus of compound metal body, the car body operation, front-wheel, trailing wheel roll, the metal body endoporus of right-hand member is locked dolly after inserting sealing ring, rotation tensioner handwheel is close to the back fixed mount, nut compressing sealing ring in the time of the pulling tension shaft;
3, adjust micro-handwheel, be close to preceding fixed mount, promote the fine setting screw mandrel and drive sealing flange simultaneously, make and to be reached high-intensity sealing by compound metal body;
4, the clear water of low pressure and mass flow in the left end fixture flush port, self-locking behind body internal memory Qing Dynasty water, open the right-hand member high pressure intake, pour the water that pressure is 15～20Mpa according to material, caliber, deformation force parameter, 10 seconds of voltage stabilizing, make to be reached radially by compound metal body, vertically full distortion is finished compound;
5, get rid of by the water in the compound metal tube after the pressure release.
The manufacture method of metal composite pipe of the present invention, the deficiencies in the prior art have been overcome, compound pipe workpiece quality is reliable, and compression resistance is strong, adopts that waterpower blow-up composite algorithm has that recombination velocity is fast, metal is even, corrosion resistance is good, long service life, elegant in appearance, characteristics that cost is low.
Description of drawings Fig. 1 is a waterpower blow-up composite high pressure sealing device
Among Fig. 1: 1 be by compound metal body, 2 for sealing ring, 3 for car body, 4 for the tensioner handwheel, 5 for tension shaft, 6 for nut, 7 for micro-handwheel, 8 for the high pressure intake, 9 for preceding fixed mount, 10 for the back fixed mount, 11 for lining, 12 for front vehicle wheel, 13 for rear wheel, 14 for sealing flange, 15 for the fine setting screw mandrel.
Specific embodiment embodiment one
Stainless steel tube material 304 φ, 76 * 0.2 * 6000mm and carbon steel tubing A3 φ 75 * 2 * 6000mm are combined into outer multiple tube by the blow-up composite methods, at first the outer surface of carbon steel tubing are taken turns mechanical grinding with round steel wire, remove scale on surface; Again with the giant flushing, be enclosed within on the carbon steel tubing after the oven dry after the inner surface of stainless steel tube purified with detergent; Be placed on that to carry out blow-up on the waterpower blow-up composite high pressure sealing device compound; Will be inserted in the sealing ring of left end by the endoporus of compound metal body 1, car body 3 operations, front-wheel 12, trailing wheel 13 roll, the metal body endoporus of right-hand member inserts sealing ring 2 back locking dollies, rotation tensioner handwheel 4 is close to back fixed mount 10, and nut 6 compresses sealing ring 2 in the time of pulling tension shaft 5; When having trace not tight when sealing, can adjust micro-handwheel 7, fixed mount 9 before being close to promotes fine setting screw mandrel 15 and drives sealing flange 14 simultaneously, makes and will be reached high-intensity sealing by compound metal body; The clear water of low pressure and mass flow in the left end fixture flush port, right-hand member high pressure intake 8 is opened in self-locking behind body internal memory Qing Dynasty water, according to material, caliber, deformation force CALCULATION OF PARAMETERS, pours the water of certain pressure, and pressure is 18Mpa, voltage stabilizing 10 seconds.Make to be reached radially by compound metal body, vertically full distortion is finished compound; By compound metal tube finish compound after, pressure release is got rid of by the water in the compound metal tube, flows to rear water box.
