Embodiment 1

[0038] The invention discloses a production method of a composite steel pipe:

[0039] Steel coil processing: between the austenitic stainless steel plate layer (austenitic stainless steel 00Cr20Ni18Mo6CuN) and the carbon steel plate layer (carbon steel Q195), a nickel-based alloy bond with a thickness of 0.5-1 mm (preferably 0.6 mm) is deposited Layers to obtain prefabricated laminates; then put the prefabricated laminates into the heating furnace and heat at 1200 ° C for 32 minutes; finally, the prefabricated laminates after high temperature treatment were extruded on the extruder to obtain a thickness of 2 mm thick steel plate, finally put the steel plate into coil;

[0040] Then use a slitting machine to divide the steel coil into strips, and then weld the steel strips into pipes, wherein the austenitic stainless steel plate layer is the inner layer of the steel pipes, and then cut the welded steel pipes to length according to the needs of use to obtain rough steel pipes; ...

Abstract

The invention discloses a producing method for a composite steel pipe and a water-carrying deburring machine applying the same. According to the technical scheme, the producing method is characterizedby sequentially comprising the following steps of steel coil processing, steel coil striping, welding pipe forming, fixed-length cutting, and cutting opening deburring. The water-carrying deburring machine comprises a storing seat, a polishing seat arranged at one end of the upper surface of the storing seat, a driving device rotatably arranged on a rotating body of the polishing seat and drivingthe rotating body to rotate, and an inner polishing block and an outer polishing block arranged at the polishing end of the rotating body, a spacing adjusting piece is arranged between the inner polishing block and the outer polishing block, the water-carrying deburring machine further comprises a water seeping assembly arranged between the rotating body, the inner polishing block and the outer polishing block, and the water-carrying deburring machine further comprises a clamping seat, a plurality of inner clamping plates and a plurality of outer clamping plates oppositely arranged on the clamping seat through a synchronous clamping assembly. According to the processing method and the water-carrying deburring machine, a steel plate is prefabricated, then the steel plate is processed intoa pipe, the quality of the steel pipe is controlled by controlling the quality of the steel plate, the operation is more convenient, the special water-carrying deburring machine is used for polishingthe steel pipe, and the quality pass rate of the steel pipe is high.

Description

technical field [0001] The invention relates to the field of steel pipe production, more specifically, it relates to a production method of a composite steel pipe. Background technique [0002] Due to the combination of the properties of various steel materials, composite steel pipes have the advantages of good corrosion resistance and high strength compared with ordinary steel pipes, and are widely used in water conservancy, construction and other fields. [0003] The existing Chinese patent application publication number CN103216682A discloses a composite pipe and a manufacturing method thereof. The composite pipe includes a base pipe and a corrosion-resistant alloy liner mechanically combined in the base pipe. The inner circumference of the end of the base pipe is provided with a corrosion-resistant alloy surfacing layer, and the inner end surface of the corrosion-resistant alloy surfacing layer and the end surface of the corrosion-resistant alloy liner The length of the...
